The Self-Hosted Cloud

For a while I’ve wanted to do a series on how to set up your own “cloud” services, written from a newbie perspective. The goal is to help the common computer user extricate themselves from commercial and ad-supported services that tend to have your data and content surveilled, monetized by AI, and censored.

Just writing up some rough notes on where I think the direction of this project should be. This is a work in a progress:

Tips, Tricks, and Notes on running RAID1 and RAID5 on XCP-NG: Part 2

This is a continuation of a series. See Part 1 here.

Now that I have the base system installed on a RAID1 array, along with a Local Storage Repo residing there, I want to create an array for “bulk” storage. I have 3 8TB disks I want to put into a RAID5 array. This will give me a 16TB block device I can use as a sort of home NAS. Since this is RAID5, we can more efficiently expand this storage just by adding another 8TB+ disk. Additionally, I can use LVM to effectively split this storage between NAS storage and another Local Storage Repo for larger VM disk allocations.

Prep the disks

Before we do anything, we need to adjust the device timeouts on EACH drive you have installed. It’s not uncommon for SATA to take a long time to recover from an error, and if this results in a controller reset, you can risk RAID array failure and data loss. For more info on this, I would recommend reading . This article mentions setting the timeout on the disks. In my case, even though the command to set the timeouts didn’t fail, it never seemed to work, as the timeout values could not be listed and verified. Instead, to be safe, I’d recommend applying the 180 second (3 minute) timeout to all the drives you have in your system using this command:

for disk in `ls /sys/block/*/device/timeout` ; do echo 180 > $disk ; done

Then add a udev rule so that it applies on startup AND when new drives are inserted:

cat << EOF > /etc/udev/rules.d/60-set-disk-timeout.rules.test

# Set newly inserted disk I/O timeout to 3 minutes
ACTION=="add", SUBSYSTEMS=="scsi", DRIVERS=="sd", ATTRS{timeout}=="?*", RUN+="/bin/sh -c 'echo 180 >/sys$DEVPATH/timeout'"

systemctl restart systemd-udevd

Next, I would recommend removing all partitions on each disk and re-setting the disk labels to GPT. Beware! This and pretty much everything to follow is destructive. Be sure you are working with the correct disk! Checking the “dmesg” command output after inserting a new disk is usually how I verify.

parted /dev/sdz

# Respond with Y to confirm all data on the disk will be lost

Partition the drives (replacing /dev/sdz with your disk) . Repeat this for each of your disks:

echo -en "mklabel gpt\nmkpart primary ext4 0% 100%\nset 1 raid on\nalign-check optimal 1\nprint\nquit\n" | parted -a optimal /dev/sdz

RAID5 and LVM Setup

Now, let’s build our RAID5 array:

mdadm --create --verbose /dev/md6 --level=5 --raid-devices=3 /dev/sdx /dev/sdy /dev/sdz

# Set up mdmonitor mail
# In /etc/ssmtp/ssmtp.conf:

# In /etc/mdadm.conf:

Then partition the resulting md device to have one large LVM partition

gdisk /dev/md6

# Commands within gdisk...
# You should see no partitions

# Hit Enter (3x) when asked for partition number, first, and last sectors
# Use a Hex code of 8e00 for the filesystem type of Linux LVM
# You should then see something like this as your partition table, with a different size, obviously:
Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048     31255572446   14.6 TiB    8E00  Linux LVM

# Write partition table and exit gdisk:

# Answer "Y" to confirmation to write GPT data

To clarify the above, here are the commands that are run in gdisk:

(p)rint partition tables
(n)ew partition
(enter) Use partition number 1 (default)
(enter) Start at first sector on device (default)
(enter) End at last sector on device (default) 
(8e00) Linux LVM partition code
(p)rint the partition table
(w)rite the partition table and exit 

Next, let’s set up LVM using the partition:

# Tell the kernel to reload the partition table
partprobe /dev/md6

# Create the Physical Volume
pvcreate --config global{metadata_read_only=0} /dev/md6p1

# Create the Volume Group "BulkStorage00"
vgcreate --config global{metadata_read_only=0} BulkStorage00 /dev/md6p1

# Set the volume groups active so they come back up on reboot
vgchange --config global{metadata_read_only=0} -ay

### ??? Edit /etc/grub.cfg and remove "nolvm" from the "XCP-ng" menu entry

# Not sure if this is needed, but doesn't hurt (rebuild init ram fs)
dracut --force

Activating Volume Groups on Boot

Disclaimer: I know, I know. This is admittedly a hack. There’s probably a better way of doing this that fits within the design of XCP-NG that I’m not aware of. If someone suggests a better way of handling this, I’ll gladly update here.

When we need to reboot, our Logical Volumes won’t be active. I believe this has something to do with XCP-NG/XenServer’s unique handling of LVM. I’ve banged my head on this problem for far too long, so begrudgingly, here’s the workaround to it:

# Make rc.local executable
chmod u+x /etc/rc.local

# Enable the rc.local service
systemctl enable rc-local

# Add our vgchange activation command to rc.local
echo "vgchange --config global{metadata_read_only=0} -ay ; sleep 1" >> /etc/rc.d/rc.local

Local Storage Repository

Now let’s create a 200GB logical volume (start small as we can expand later)

lvcreate --config global{metadata_read_only=0} -L 200G -n "RAID_5_Storage_Repo" BulkStorage00

And create the Storage Repo in XCP-NG (using the “ext” filesystem for thin provisioning)

xe sr-create content-type=user device-config:device=/dev/disk/by-id/dm-name-BulkStorage00-RAID_5_Storage_Repo host-uuid=<tab_to_autocomplete_your_host_uuid> name-label="RAID 5 Storage Repo" shared=false type=ext

And that’s it! The above creates another set of LVM layers on top of your existing BulkStorage00/RAID_5_Storage_Repo logical volume which consists of a physical volume, volume group, and logical volume that are natively managed by XCP-NG. You should now have a 200GB storage repo named “RAID 5 Storage Repo” in XCP-ng Center and/or XOA. Next, let’s set up a bulk store to share out via SMB/CIFS…

Bulk Storage Share Setup

First let’s allocate 500GB of that space for another Logical Volume named “BulkVolume00”

lvcreate --config global{metadata_read_only=0} -L 500G -n "BulkVolume00" BulkStorage00

And lets format it with EXT4

mkfs.ext4 /dev/BulkStorage00/BulkVolume00

Let’s set up /etc/fstab (edit with vi or nano) to mount the device by adding the following line to the end of the file

/dev/BulkStorage00/BulkVolume00 /opt/BulkVolume00       ext4    rw,noauto        0 0

And lets create a mount point for the device and mount it

mkdir /opt/BulkVolume00
mount /opt/BulkVolume00

We’ll also want to set this up to mount on boot (note, as above with our Storage Repository, we have to use a workaround to mount this AFTER the logical volumes have been activated

echo "mount /opt/BulkVolume00" >> /etc/rc.d/rc.local

And lastly, lets get that shared out via SMB

# Install Samba server
yum --enablerepo base,updates install samba

# Make a backup copy of the original SMB configuration (just in case)
cp -rp /etc/samba/smb.conf /etc/samba/smb.conf.orig

Then edit /etc/samba/smb.conf, erasing the contents and using this as your template:

        workgroup = MYGROUP
        # This must be less than 15 characters.
        # Run "testparm" after editing this file to verify.
        netbios name = XCP-NG-WHATEVER
        security = user
        map to guest = Bad User

	comment = Bulk RAID5 Storage Volume
	path = /opt/BulkVolume00
	guest ok = yes
	writable = yes
        read only = no
	browseable = yes
        force user = root
	create mode = 0777
	directory mode = 0777
	force create mode = 0777
	force directory mode = 0777

Note that this is set up to be very permissive for use on a secured/home network. Setting this up for more elaborate security is beyond the scope of this tutorial.

Next let’s (re)start samba, and poke the required holes in the firewall

# Verify your smb.conf is sane
# Enable and start samba services
systemctl enable smb.service
systemctl enable nmb.service
systemctl start smb.service
systemctl start nmb.service

# Edit "/etc/sysconfig/iptables" and add the following lines below the port 443 rule:
-A RH-Firewall-1-INPUT -m conntrack --ctstate NEW -m udp -p udp --dport 137 -j ACCEPT
-A RH-Firewall-1-INPUT -m conntrack --ctstate NEW -m udp -p udp --dport 138 -j ACCEPT
-A RH-Firewall-1-INPUT -m conntrack --ctstate NEW -m tcp -p tcp --dport 139 -j ACCEPT
-A RH-Firewall-1-INPUT -m conntrack --ctstate NEW -m tcp -p tcp --dport 445 -j ACCEPT

# Then restart iptables to apply
systemctl restart iptables

Finally, test this share in Windows (or your favorite SMB/CIFS client) by opening the URI to your server’s IP, ex: \\\BulkVolume00\

The next installment of this series will be a rough collection of tips on managing this XCP-NG RAID5 combo. Stay tuned.

Disabling the Windows 10 “This app is preventing you from restarting/shutting down/logging off” screen

Sometimes Microsoft befuddles me. Scratch that. Not sometimes. Usually.

Take for example the “new” log-off/shutdown/restart behavior. Used to be by default in Windows 7 that when you shut down, you’d receive prompts about applications that were preventing shutdown. In most cases, this would be an unsaved document. You could simply click desired option (Save, or Don’t Save), and Windows would continue logging you out, unless it came upon another unsaved document. Rinse and repeat until you’ve closed all your unsaved documents, and Windows would finally log you out.

Now in Windows 10, you get that generic blue screen with a list of apps left to shut down, with only two options: Shutdown anyway, or Cancel. Neither of these are good options. One stops your shutdown, and you have to manually go through all your open apps and close them one by one. The other simple force closes all your apps, losing anything you might not have saved.

Thankfully, this setting is easily reverted to the legacy behavior with either a registry entry change, or a Group Policy change (which affects the same registry entry). To apply, use this reg file: Enable-AllowBlockingAppsAtShutdown.reg

Windows Registry Editor Version 5.00


You can also find this setting in the Group Policy editor (Start, Run: gpedit.msc) under Computer Configuration > Administrative Templates > System > Shutdown Options > Turn off automatic termination of applications that block or cancel shutdown:

Override Windows Explorer Win Key Hotkeys

For years now I’ve been using an awesome clipboard manager utility by JoeJoe Soft called ArsClip. One of the nice features of the program is the ability to set a custom hotkey for the clipboard manager clip list. In my case, I like to use the Ctrl+Win+V combo to invoke this feature. This can be set in the ArsClip INI file with these variables set:



There’s one problem though: Apparently Microsoft reserves the use of the Win key. If, as in my case, you start using Win+Something and it works for a while, a Windows 10 update could suddenly replace your cool clipboard functionality with something like, say, their own lame clipboard manager, or in my case, something completely useless and dumb like “Shoulder Taps“.

I suspect that there may be a clean way of having AutoHotKey take over these hotkeys and re-route them to ArsClip (or whatever application you want), however I couldn’t figure out how to make that happen.

There is a solution however. If you can start your app before the Explorer shell gets a chance to, then you effectively reserve those hotkeys for your app, and Explorer can’t use them. For a while, I’d do this by killing the explorer.exe process, run ArsClip, then re-start Explorer. Not ideal, but workable. I eventually came up with a better solution: Fire up ArsClip upon login, before Explorer starts, by using the Userinit registry key and a batch file to manage the timing. Here’s the batch file (C:\USERINIT.BAT):

@echo off
REM Start ArsClip and continue
start "" "C:\Program Files (x86)\ArsClip\ArsClip.exe"
REM Wait 2 seconds for ArsClip to start up and register hotkeys
timeout /t 2
REM Start the Explorer shell via UserInit.exe

Save that to C:\USERINIT.BAT
Then make this Registry modification (or save this to a .reg file and run):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]

Now when you log off and back on, ArsClip will start before Explorer, and your Win+Ctrl+V hotkey will work! Dirty hack? Maybe. If you know a better solution (such as some AHK magic as mentioned above) I’d love to hear about it.

Note that this modification will apply to all users of your computer. If you needed it to apply to just yourself, you may need to wrap it in some batch file logic, like so (untested):

@echo off
if '%username%' == 'myusername' goto hotkeyapps
goto userinit

start "" "C:\Program Files (x86)\ArsClip\ArsClip.exe"
timeout /t 2
goto userinit


Good luck!

Tips, Tricks, and Notes on running RAID1 and RAID5 on XCP-NG: Part 1

Note: This article series is specifically written with XCP-NG in mind, however if you are using XenServer, it is possible that some if not all of this is still applicable. YMMV.

Recently when installing XCP-NG on my home server, I ran into some persistent issues with setting up RAID1 on my boot disks, and setting up RAID5 for my secondary/bulk Local Storage Repository. Here are my notes and tips on succeeding with an installation such as this.

I have a chassis with 2x400GB SATA disks in a RAID1 array used for the boot disks that hold the OS and the first Local Storage Repository, and 3 8TB SATA disks in a RAID5 array with LVM on top, serving as both a Local Storage Repository as well as a bulk storage served via SMB/CIFS/NFS as a sort of NAS.

Installation Prep

Starting from scratch, we might want to wipe all the partition tables, boot records, and/or RAID superblocks on each target disk. This is optional, but if you know you don’t care about the data on your disks, it should help ensure success in case you had a prior installation of a RAID superblock or the GRUB bootloader on any of the disks. If you care about the data on any of the disks in your system, power off, unplug those disks, and start over. Boot up the installation disk, and type Alt+F2 to get to the console, then run the following:


for dev in `ls /dev/md*` ; do mdadmin --stop $dev ; done

for dev in `ls /dev/sd[a-z]+` ; do echo "Wiping Partitions and MBR on $dev" ; dd if=/dev/zero of=$dev bs=512 count=1 ; done

Next, reboot to start the installer over again, ensuring we start with a clean slate. Run the following to verify:


You should see no partitions or raid labels (ie, md127) on any of your target disks. If you do, you may need to re-run the above and try again.


Proceed as normal with the installation prompts, selecting the Software RAID option when it comes up.

Select the two (or more) disks you wish to add to the RAID1 array, then enter Create

Select your RAID disk as the install target (usually md127)

Select your RAID disk for your local storage (usually md127)

Proceed as normal with installation

When the install starts, type Alt+F2 to go to the CLI console

Run this to see the RAID resync process:

while true ; do tput clear ; date ; mdadmin --detail /dev/md127 | grep -v ^$ | grep -e ^ -e "Resync Status.*"; sleep 10 ; done

You should see a line starting with “Resync Status” indicating the percentage complete.

You may type Alt+F1 to go back to the installation progress screen.

Once the installation is complete, DO NOT REBOOT YET! I suspect this was the cause of an issue I had on one of my attempts doing this. The RAID1 array needs to finish syncing, or else you may be missing the required MBR/GRUB information on one of your disks, and your system may fail to boot if the non-synced disk happens to be the first in your BIOS/HBA boot order. Type Alt+F2 to go back to the CLI console and re-check the Resync Status progress. Once it reaches 100% complete and is in a State of “clean”, you may proceed.

Type Alt+F1 and finish the installation as normal.

A new era, a new look

Well, the Atathualpa theme has served me well since I first migrated my blog to WordPress from Slashcode (yeah, crazy). However we live in a new world now, with a growing majority of web traffic coming from mobile devices. It’s time I got with the times and used a responsive design theme. So I’ve made a switch to the TwentyFifteen theme. I’m going minimalist for now, and will likely bring modifications back in as I see value.

Jetpack Broke My Comments


So apparently “JetPack Comments” broke my comments, causing recent comments to get posted to the wrong thread. They claim it’s not their fault, saying that it’s due to a lack of implementation of the comment_form() function in WordPress, but Atahualpa seems to support this just fine. Well, anyhow, for now I’ll be disabling JetPack Comments on my blog. So if you want to comment, you’ll have to sign up. I know. It’s a pain. I’ll get it fixed.

Update 6/10/2015: After switching themes to TwentyFifteen, the problem seems to be gone. JetPack Comments re-enabled.

Adfree Breaks Pinterest on Android

If you’re like me, you like keeping your Android device screen free from ads. AdFree from BigTinCan is an invaluable tool in assisting with this by customizing your hosts file on a rooted Android phone so that any ad network links get redirected to your phone, effectively disabling ads. The side effect of using host-based ad blocking is that sometimes valid sites get blocked as well.

“I don’t always do Pinterest, but when I do, I prefer pinning homebrew stuff.” And unfortunately, Adfree blocks pinning on Android. You’ll notice this when doing any pin outside of a re-pin (ie, within your pin feed). The app will churn saying it’s finding images, but then finally fail with the popup error “Sorry, couldn’t find any pinnable images on this page”. The issue is that the Pinterest app requires access to a few hostnames that Adfree hijacks:


This solution to this is fairly simple. Thankfully, BigTinCan offers an option to set up a customizable exception list but of course you’ll have to register for a free account. Once you have registered, add exceptions for each of the hosts above. Then sign in to your account on the AdFree android app and update your hosts. You should now be able to pin to your heart’s content.

Let me know if this helped you!

Pebble Smartwatch Skins

One of my biggest beefs with the Pebble is the plastic case. These guys have a solution to not only the scratchability of the case, but the plain black style. The woodgrain one looks really nice, and is probably the one I would go with if I were to get a Pebble.

HowTo Resolve StartSSL (StartCom) Domain Blacklisted: Domain appears on a blacklist

Does this look familiar to you?


Welcome to my world. Not sure at this point how I got on this list, how to get off it, or even where this list is. But perhaps my findings will help you resolve the same issue for your domain. At this point, my suspicion is that it’s due to and odd report from Google Safe Browsing that “Yes, this site has hosted malicious software over the past 90 days. It infected 0 domain(s), including .”. It would be great if I knew what the malware/badware is/was so that I could remove it. Even more odd is that my supposed infection infected no other sites.

Oh well. More to come…

Update: I’ve emailed “Certmaster” and they responded letting me know that they see my domain on Google’s Safe Browsing blacklist results. Oddly enough, here are the results:

I see the report that “Yes, this site has hosted malicious software over the past 90 days. It infected 0 domain(s), including .” What’s odd about this is that when I check my Google Webmaster tools, the site reports that “Google has not detected any malware on this site.”, and it seems I’m not the only one. Not sure if I’m just bitten by a previously unseen issue that I’ve since cleaned up with WordPress updates or what.

Given the date that is shown above (2013-05-04), I’d guess that the “past 90 days” implies I’ll have to wait until 2013-08-04 for this status to clear. I guess that’s the penalty I pay for lack of diligence in monitoring the updates and health of my server up until then. If you’re saying to yourself “I can’t wait that long!”, you do have the option of paying StartSSL the fee required for them to manually intervene in what would otherwise be an automated process. I choose to wait it out: I don’t really need SSL for anything practical. For my purposes, it’s just for the sake of writing articles like this: research and writing howto’s based upon my experiences. So I’ll be waiting out the presumably prerequisite “90 days” for the sake of research.

See you on 8/4 with an update!

Update 8/15: As the saying goes: “Time heals all wounds”. I’m now off the naughty list for Google. Now to (re-)try obtaining a cert from StartSSL…

Solution to the NVidia Gray/Grayscale Screen Problem

Today I came in to work to find that the video output for my Dell Latitude e6520 laptop’s NVidia head was displaying in black and white. At first I thought that the problem was a driver bug, something wrong with the video memory, or a faulty display. But eventually I found out that, somehow (without any user interaction with the applicable setting), the “Digital Vibrance” setting was set to 0%, when it should be 50%. Below you’ll see a simple annotated screenshot showing where you can quickly fix this.

Streaming RTMP with VLC and RTMPDump

This quick post is as much for your benefit as for the benefit of my memory…

To stream RTMP with VLC, you’ll need rtmpdump, which you can get here: I used, though you may be able to use the latest version. I also had VLC 2.0.6 32-bit installed. Once installed, you can run the following from a cmd window:

rtmpdump.exe -r “rtmp://” -v -o – | vlc.exe –

This worked nicely for me. YMMV. Good luck!

FFMPEG “Server error: Not Found” with Short URLs

Just a quick post about a problem I helped a buddy of mine resolve. He was setting up a Helix media streaming server, and was trying to capture the stream data to a file with the following command:

ffmpeg -i “rtmp://” out.flv

The result was this error in the output:

[rtmp @ 0x28e1dc0] Server error: Not Found

Oddly enough, the connection information shown on the Helix console showed that a strange URL was being requested. Upon further investigation with Wireshark, I found that this was the request being made.


Note that “\360” is a hex character. For some odd reason, it would appear that ffmpeg improperly handles short URLs, inserting a string of “\360xw0”. If you pad the URL with the current directory “./”, then the request succeeds:

ffmpeg -i “rtmp://” out.flv

This results in a request of


Which worked fine in our environment.

For future reference, I was running this ffmpeg version (on CentOS 6.4 x86_64):

ffmpeg version N-53616-g7a2edcf Copyright (c) 2000-2013 the FFmpeg developers
built on May 29 2013 00:19:54 with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-3)

So if you’re running into the “Server error: Not Found” error on a known good URL, try padding the path of the stream with “./” and see if that fixes it for you. I’m guessing this is an ffmpeg bug, but don’t really have the access to a streaming server to troubleshoot and submit a bug report. From the time that I did have, it appears that it’s related to the .flv extension in the rtmp URL. If you drop the extension, the URL can be of any size.

Recovering the PPP Username and Password from a Centurylink Actiontec C1000A

Some time ago I wrote up a similar procedure to recover a password from an Actiontec M1000 back when Centurylink was known as Qwest (gotta love rebranding). Back then, Actiontec left the operating system a bit more open, actually placing the PPP credentials in a flat file in /var/tmp/. Nowdays, Actiontec tries to obfuscate/encrypt the password in a config XML, making it just difficult enough for most people to give up on the idea of recovering the password.

In addition to this, it would appear to the casual telnet console user that the commonplace busybox shell had been removed or made inaccessible, removing the ability to peer into the embedded linux operating system underneath, and replacing it with a stripped-down properietary shell with limited commands. However, dig a little deeper by trying the undocumented “sh” command, and you’ll find that busybox is alive and well on this device, exposing the configs and services that support the router’s functions. Since the configs contain the encrypted password, we can’t directly extract them from there, however fortunately for us, pppd (the service that authenticates and creates the DSL connection) requires the password to either be kept in plain text in a flat config file (not the case here) OR have the password specified on the command line. The “ps” command on these devices has been handicapped to only display 80 columns, leading to output similar to this:

1623 admin      1144 S   pppd -c ppp0.1 -D 0 -i ptm0.0 -u “your___username@qwe

At first, when I saw this, I figured it was another dead end, until I realized that “/proc/(pid)/cmdline” displays the command line of any running process. And fortunately for us, Actiontec left “pidstat” enabled in busybox, making reading those command line arguments fairly simple with a single command:

 > sh -c “/usr/bin/pidstat -l -C pppd”
Linux 2.6.30 ((none))   05/23/13        _mips_  (2 CPU)

14:59:38          PID    %usr %system  %guest    %CPU   CPU  Command
14:59:38         1623    0.00    0.01    0.00    0.01     1  pppd -c ppp0.1 -D 0 -i ptm0.0 -u “” -p “AbCDEfgH” -f 0 -k -P “AbCDEfgH” -M 1492

And there you have it! In this case, I’ve altered the password output (shown as AbCDEfgH) to protect my own privacy, but it’ll look similarly like jumbled letters and numbers on your command line. Also note the “” username. Qwest used to be the LEC in my area, and likely the transition hasn’t been made to the newer branding in the back-end systems. Your situation may be different.

Also, in case you hadn’t figured it out by now, you’re going to need telnet console access. My modem’s console admin password was not the default “admin”, nor the admin password listed on the box. I had to log into the web UI, enable remote console, and (re)set the console password. After that, you should be able to log into the telnet console with “admin” and the password you’ve set.

Lastly, one might ask “Why would I want to obtain this password?”. My personal reason is that eventually I want to replace this leased modem with one I’ve purchased, and use it in transparent bridging mode (using RP-PPPOE to terminate the PPPoE connection and it’s leased static IP on my firewall). When that day comes, I’d like to be able to do the swap without interacting with Centurylink. Call them by whatever new brand they’ve been changed to, Ma’ Bell is always a pain to talk to.

Good luck to you!

Welcome to the rest of your week…

Where the hell is this global warming I’ve been hearing so much about.
