PM Software Stack
PMSS, short of PM Software Stack is a compilation of scripts to manage single server side seedbox configuration, turning instantly and conveniently an regular Debian 6.0/7.0 server into a seedbox. The PMSS does not contain multi-server management utilities nor clustering support out-of-box, but does include PM Master GUI automatic remote update features. Debian 6.0 squeeze support is considered stable. PMSS currently only supports rTorrent+ruTorrent stack. Multi-Server management is done via API with central server, with strict authentication and limited scope for security.

- 3.4 Changes 2011
- Semi-automatic installation
- Fast and easy creation of new user accounts with quota and rTorrent resource limits, etc.
- Easy user resource reconfiguration
- Autonomous, idempotent Lighttpd configuration
- Autonomous configuration of basic server features
- Compiling rTorrent + libTorrent + Quota + XMLRPC from source.
- Multiple redundancy levels for rTorrent
- Lighttpd redundancy / autorestart
- Basic server optimizations to maximize performance
- Terminate, Suspend/Unsuspend users
- Webdav for users
- Other basic management scripts
- Another rTorrent update, there was a regression on thread names, this is now fixed
- rtorrent config: Bumped for larger range of possible scgi ports for rtorrent
- Added dhtPort variable for lib rtorrentConfig.
- New rtorrent config template file, added the new config variable, max uploads global into the template, and increased range of ports
- Changed allocations for less upload slots per unit of ram, since RAM amounts have quadrupled since originally setting this while disk speeds are practically the same.
- lib/rtorrentConfig: Added readConfig and readUserConfig methods
- lib/rtorrentConfig: Updated headers, version, copyright.
- lib/rtorrentXmlrpc: Beginnings of rtorrent communication lib
- rtorrent compile: changed this to happen in /tmp, there is a regression where trying to compile libtorrent elsewhere will fail, probably rtorrent too!
- new rtorrent version is based on the last one, with few select updates manually applied
- install.sh changed to reflect the updated version
- lib/rtorrentConfig: Order of setting variables was incorrect, leading to a configuration bug which would lead to rTorrent not starting
- util/update-step2: Removed old .rtorrent.rc updates (umask etc. related, very deprecated), and added new configure update based on the readConfig (scgi port won't change etc.!). However with local template it's likely no practical changes happen.
- Added first piece of callback data for new management system, diskUsage under util/remote
- Minor revisions to install.sh and code cleanup
- Update to latest rTorrent, 0.9.4/0.13.4
- terminateUser.php: added groupdel as well for the user group
- Slight refactoring of terminateUser.php
- terminateUser.php: --confirm now first, before username
- Update on versioning issue with installing libmediainfo, mediainfo and libzen. fixed and these will be now installed on wheezy as well.
- libdigest-sha1-perl pkg doesn't exist on wheezy so it was preventing several other packages from installing
- libdigest-sha-perl pkg now installed on wheezy
- Styling of info tab, info.php/stats.php
- pulsedBox upload: Fixed for new style urls, should work with both subdomain and subfolder setups now.
- Installer package updates so that PMSS should install into Debian 7 without a hitch now, previously 2 packages were missing.
- userTransfer.php: Tries to retry 20 times with 15-120sec delay. Necessary since OVH has introduced new bw limitations: Connections are cut at random, exact rules unknown but result is that transferring user data connections are cut at random. This has been tested via multiple DCs to be true, from multiple OVH DCs.
- userTransfer.php: At the end display user's old server password IN CASE the 20 retries is not sufficient.
- install.sh: updated libxmlrpc URI to the new one.
- update-step2: Added wheezy repos
- update-step2: Made wheezy repo update
- update-step2: Some refactoring in regards of repo updates
- cron/trafficLog: Updated traffic parsing to support wheezy
- install.sh: Moved apt-get install rar unrar to it's own command due to OVH wheezy template issues
- install.sh: Removed some commented out things, blast from past type of things
- install.sh: Updated queue read ahead to double size
- install.sh: Updated header comments
- install.sh: moving around php5 installation due to continuing OVH template issues
- install.sh: looks like the OVH Debian 6 wants to install apache2 with php5-geoip, so moved around the php5 modules and after their installation remove apache2
- install.sh: Added code for removing OVH installed Apache2 which is quite hard to get fully removed, and causes PMSS installation to fail
- update-step2: Added packages required for autodl irssi
- update-step2: Added creation of /etc/autodl.cfg
- trafficStats month data traffic is now for the past month, not since beginning of calendar month.
- addUser: fixed typo (use of undefined constant)
- addUser: fixed argv optionals checking
- userConfig: added several checks for user existing
- created userTrafficLimit under utils to set the traffic limit
- addUser: fixed typo in pathname for traffic limit data
- userConfig: added setting traffic limit
- userConfig: now restarts rTorrent (near instant)
- created trafficLimits cron which checks traffic limits. Communications module is still required before traffic limits can be enabled
- update-step2: added smartmontools to pkgs to be installed
- trafficStats now parses 23k lines before 1st of August, 2013 because the traffic logging speed has been lowered at 17th April update -> showing just 1½ weeks initially. Time limit for that so it will not slow down always.
- Added lib/traffic.php for trafficStatistics class
- Refactoring showTraffic
- stats.php shows this traffic data on info page now
- Added cron/trafficStatistics.php which saves traffic data to .trafficData periodically (once per hour)
- Decreased traffic data saving to once per 5 minutes
- Also now monitoring since beginning of the month
- showTraffic now uses the "cached" data saved by trafficStatistics
- util/userTransfer.php now puts in request for rTorrent restart after transfer is complete
- addUser optional argument for traffic limit in TBs
- update-step2 now checks, creates and chmods a bunch of required directories
- Added new remote calls to serverApi, had forgotten this
- Dropped traffic logging to 4 min intervals, unfortunately this means showTraffic for 15mins is totally skewed, and maybe noticeable skew on the hourly
- updateQuotas cron now every second minute
- checkInstances now every 10mins from 15mins, making faster 2nd level redundancy for rTorrent
- changed updateQuota cron's API calls to base the call time to modify time of /scripts ie. roughly time the system was installed. This way the requests don't get pooled up at same minute from all servers
Release of 10th of Jan features as well. Several bug fixes in this release.
- showTraffic now prunes erroneous data from the log
- trafficLog cron now checks for erroneous data and logs it
- updateQuotas sends the user quota and df data only once per hour
- Absolute path to iptables on setupNetwork + makeMonitoringRules so it actually works on boot time :)
Waiting for release, pending server side support.
- updateQuotas now reports user quota to API server as well
- updateQuotas reports df to API server
- lib/users.php error message when issues with /home
- setupNetwork won't try to enact empty ruleset anymore
- fileCopy updated help message. This is pretty much useless nowadays in any cas and might be deprecated/removed in future release
One of the DCs changed debian installation template so fixes for that. Issues with rTorrent compilation, lighttpd etc.
- Changes on install.sh package removals (apache2 not getting removed??)
- Removed munin installation from install.sh
- Added installation of pkg-config make openssl
- Fixed on update-step2 rtorrent compilation
- Install.sh now executes /scripts/update.php but does not do API key setup, it's done on the update script
Quick performance related hot-fix, and one performance update.
- trafficLog now deletes the traffic log file from tmp, this was causing slowdowns etc.
- rTorrent peers better configuration, min from 14 to 6 and max from 21 to 32 per "resource block" (Resource block=250Mb of rTorrent ram). This affects only new accounts, reconfigured and recreated.
Work on the new API - note this is still largely untested so far
- API create jobs dir + chmod added
- API function to make calls to server added
- API function to create authorization for remote calls added
- API make call userTraffic added
- trafficLog cron fix users check
- trafficLog reports traffic to server
- serverApi typos fixed (had not been tested before)
- serverApi create dirs bugs fixed
- serverApi logger was missing newline and has been added
- serverApi some commenting added
- fixed timestamp on scriptsInc writeLog
- trimming some elements in serverApi which due to unrelated reasons have newline at end
This update also releases the changes of 7/12/2012 which were postponed due to QA reasons.
- Removal of netcat packages in update-step2 and install script
- Added count checks for users in makeMonitoringRules and recreate lighttpd rules scripts
- Copied some standard packages from update-step2 to install.sh
- Removed some apt packages from update-step2 which has been on install.sh for a *Really* long time
- Removed some irrelevant apt-get lines from install -> duplication
- Added p7zip-full package to update-step2 installation
- Fix showtraffic weekly data, was only considering ~2/5ths of the data
- ShowTraffic compares now user count, not the string returned in order to determine if there is users setup
- More uniform ShowTraffic display output, which is also programmatically easy to parse

- setupRootCron both cron force-reload and restart to ensure new cron will be enabled
- Temporarily disable all QoS & Fair share, unintentional effects
- Display traffic used per user on week, daily, hourly and 15min basis. Note: 15min is slightly inaccurate due to datalogging delays (2min interval), hourly is within acceptable error margin

- Removal of cpuload + autotools rutorrent plugins. CPULoad being misleading at best, autotools haven't worked for ages and developer is MIA.
- Changed fetching libmediainfo packages from pulsedmedia.com instead of sourceforge.
- Choosing libmedia info + libs based on debian version. Now Debian 6.0 should be fully supported in updates.

- Fixed some typos in update-step2
- Added iotop and cfv to be installed from apt repo.
- Added -m toggle for htpasswd because for some reason this is not default in Debian Lenny
- Added SSL support (self signed cert), just change http to https

- Update-step2 creates SSL key automatically utilizing the server hostname, removes old deprecated key
- Added .irssi/config to user dirs, autojoining to #PulsedMedia on Freenode when irssi is launched
- Updated GUI IRC links, Chat tab and Adobe download links, with other small additional information and updates.
- Removed Network Storage tab from GUI because Dropbox is blocking pageviews coming from our system for unknown reason.
- Added Proxy information on GUI
- Update-step2 sees if .irssi/config exists and if it does not copies it there
- Chosen rTorrent SCGI port range increased from 4k to 8k.
- "fractional blocks" for config. Resource calcs are based on number of blocks, and fractions were not allowed prior.
- During update also update user crontabs. Added to both update.php and step2, to be removed from step2 after this update has seen significant adoption.
- Restarting lighttpd during update, also done doubly for now
- Moved setup api key to regular update script. In several months it will potentially be removed from update all together as it's a installation step, and included to update older nodes.
- Scripts permissions update
- updateQuotas.php -> cron to update all user quotas, as discreet user from central cron to ensure it gets updated.
- Updated root & user crontabs to reflect updateQuotas
- quotaFix now removes aquota*new files to avoid collision and thus failed update via quotacheck
- userTorrents.php : Lists the count of torrents each user has, for quicker analysis usage stats
- Permissions setup script added, which is utilized by recreateUser.
- recreateUser.php fixes
- Created recreateUser.php which recreates home dir, preserving data+session if existing. ALPHA
- Fixed saving API Key.

- recreateLighttpd backup fixed
- Added access format of: servername/user-username/, for example: localhost/user-johndoe/. Thus supporting non FQDN setups
- addUser.php calls recreateLighttpd instead of just adding the hostname, this ensures lighttpd config is always up-to-date.
- Added to both update steps recreateLighttpd. It will remain on step2 for the next ~6months to ensure every system out there will have the update update.php
- Removed the default "testing" torrents
- Upload slots global, by default 6 times the non-global upload slots. It is "forcefully" inserted even if template does not it have for the moment. this forcefull insert will be removed in the future.
- checkInstances now also checks rtorrent configs, and if changed lists them on /root/changedConfigs for admin review
Streamlined installer for faster setups :) First release of API, just one command now. Some things moved to BETA status and considered feature complete. Many bug fixes, additional commenting etc. also added
- fixed userTransfer chowning lacking -R, thus UID was transferred for many files from the other server causing incorrect permissions
- wrapped vnstat install into if !file_exists to see if vnstat is installed already.
- added username 'srvadmin' to filter list on systemUsers
- removed from installer editing munin.conf -> if used can be done manually. Interim solution.
- put install vim as first thing on installer
- setting node hostname straight after installing vim
- moved setting up lighttpd as last thing
- scripts, skel, etc are installed earlier in installation
- SSL cert + quota as last items on setup
- Executing update-step2 on installer (so you don't need to execute updater after setup to get everything in)
- /scripts/util/setupRootCron.php -> creating root conf moved out of update.php
- setupSkelPermissions.php, same reason as root cron setup
- added setupRootCron and setupSkelPermissions to installer
- Idempotent lighttpd configurator feature completed. Backups the config first.

- checkHttpd timer increased to 3 seconds before restarting lighttpd
- terminateUser timer increased to 5 seconds after trying to kill all user processes
- setupApiKey -> creates node key for API. Invoked upon setup.
- added authorization key
- removed /var/www/index.lighttpd.html
- added /var/www/index.php redir to pulsedmedia.com
- added beginnings of remote API for easier remote control management, by default in debug mode for now
- Was not actually completing shell userdeletion
- Added killing user processes (forgotten)
- added sleeping 2 seconds to allow time for rTorrent/other processes by user to die
- Added 2nd attempt to userdel after data removal
- Fixed some typos in texts
- Added check for user actually exists
NOTE: Still Alpha, non feature complete and not recommended for production use.
- checkHttpd.php added sleep between lighttpd kill and restart, to avoid PID file mismatch scenario
- First time being used
- update.php moved cron & ftp config stuff AFTER step2
- Install vnstat + vim (vim not by default on Debian 6)
- Setup interface for vnstat
- Configure vnstat for Debian 6
- Make vnstat cron jobs for Debian 5: twice a minute update (thus no support for 1GigE interface)
- Debian 5 add cron jobs to root.cron.additional config, create if needed
- GUI welcome page checking if proper quota information was passed has been added.
- GUI welcome page malformed serialized data fix
- GUI welcome page quota percentage missing % char
- GUI welcome page quota text styles: White and location
- GUI update script quota checking added (doesn't try to update when user is over quota burst limit, no more blanking GUI when update happens!)
- Users default quota information update rate has been increased to 10mins
- HDD Quota plugin commenting added
- HDD Quota plugin parser bug with bursted amounts fixed
- HDD Quota now shows USED/QUOTA instead of FREE/QUOTA. Makes more sense.
- HDD Quota "title" fixed (showing quota info) to be whole area of the meter
- Welcome page quota meter added :) Basic graph, larger and constantly visible text for quota info :)
- Basic idempotent lighttpd configurator (alpha, not suitable for production, TESTING only)
- terminateUser.php http password deletion fix, text fixes, executability.
- checkHttpd.php output lighttpd output, killall -9 lighttpd to ensure shutdown, http fetch mute removed so error gets logged
- update.php: removed apt updates because soft.sh already does this
- crons: increased check http to 4 minute intervals (avoid http timeout period issues)
Temporary fix to bypass userDb until fully utilized. You may use this update or use /scripts/util/populateUserDb.php to fix the issue.
- Changed listUsers.php to always use systemUsers.php, as fixing userDb saving introduced a bug where ie. checkInstances was not working fully (using userDb, which lacks most users in most servers)
Few bug fixes and minor features introduced.
- Update script order of items.
- Update script apt-get options for additional package installation lacked auto confirm.
- Update script support for "step 2", /scripts/util/update-step2.php is included if present, thus supporting dynamic updates
