• Redirecting or routing all traffic to OpenVPN on a Mac OS X client

  - by sdr56p

  I have configured an OpenVPN (2.2.1) server on an Ubuntu virtual machine in the Amazon elastic compute cloud. The server is up and running. I have installed OpenVPN (2.2.1) on a Mac OS X (10.8.2) client and I am using the openvpn2 binary to connect (in opposition to other clients like Tunnelblick or Viscosity). I can connect with the client and successfully ping or ssh the server through the tunnel. However, I can't redirect all internet traffic through the VPN even if I use the push "redirect-gateway def1 bypass-dhcp" option in the server.conf configurations. When I connect to the server with these configurations, I get a successful connection, but then an infinite series of error messages: "write UDPv4: No route to host (code=65)". Traffic routing seems to be compromised because I am not able to access anything anymore, not even the OpenVPN server (by pinging 10.8.0.1 for instance). This is beyond me. I am finding little help on the web and don't know what to try next. I don't think it is a problem of forwarding the traffic on the server since, first, I have also took care of that and, second, I can't even ping the VPN server locally through the tunnel (or ping anything at all for that matter). Thank you for your help. Here is the server.conf. file: port 1194 proto udp dev tun ca ca.crt cert ec2-server.crt key ec2-server.key # This file should be kept secret dh dh1024.pem server 10.8.0.0 255.255.255.0

• How to show what will be updated next pull?

  - by ???

  In SVN, doing svn update will show a list of full paths with a status prefix: $ svn update M foo/bar U another/bar Revision 123 I need to get this update list to do some post-process work. After I have transferred the SVN repository to Git, I can't find a way to get the update list: $ git pull Updating 9607ca4..61584c3 Fast-forward .gitignore | 1 + uni/.gitignore | 1 + uni/package/cooldeb/.gitignore | 1 + uni/package/cooldeb/Makefile.am | 2 +- uni/package/cooldeb/VERSION.av | 10 +- uni/package/cooldeb/cideb | 10 +- uni/package/cooldeb/cooldeb.sh | 2 +- uni/package/cooldeb/newdeb | 53 +++- ...update-and-deb-redist => update-and-deb-redist} | 5 +- uni/utils/2tree/{list2tree => 2tree} | 12 +- uni/utils/2tree/ChangeLog | 4 +- uni/utils/2tree/Makefile.am | 2 +- I can translate the Git pull status list to SVN's format: M .gitignore M uni/.gitignore M uni/package/cooldeb/.gitignore M uni/package/cooldeb/Makefile.am M uni/package/cooldeb/VERSION.av M uni/package/cooldeb/cideb M uni/package/cooldeb/cooldeb.sh M uni/package/cooldeb/newdeb M ...update-and-deb-redist => update-and-deb-redist} M uni/utils/2tree/{list2tree => 2tree} M uni/utils/2tree/ChangeLog M uni/utils/2tree/Makefile.am However, some entries having long path names are abbreviated, such as uni/package/cooldeb/update-and-deb-redist is abbreviated to ...update-and-deb-redist. I deem I can do with Git directly, maybe I can configure git pull's output in special format. Any idea?

• allow spoofing when using tun

  I have a working openvpn setup with a server and a number of clients. How would i go around allowing IP spoofing through the openvpn server? (to demonstrate security concepts)? A normal ping from client to server goes through all right: root@client: hping3 10.8.0.1 HPING 10.8.0.1 (tun0 10.8.0.1): NO FLAGS are set, 40 headers + 0 data bytes len=40 ip=10.8.0.1 ttl=64 DF id=0 sport=0 flags=RA seq=0 win=0 rtt=124.7 ms root@server:/etc/openvpn# tcpdump -n -i tun0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun0, link-type RAW (Raw IP), capture size 65535 bytes 10:17:51.734167 IP 10.8.0.6.2146 > 10.8.0.1.0: Flags [], win 512, length 0 But when spoofing a packet, it does not arrive at the openvpn server: root@client: hping3 -a 10.0.8.120 10.8.0.1 HPING 10.8.0.1 (tun0 10.8.0.1): NO FLAGS are set, 40 headers + 0 data bytes root@server:/etc/openvpn# tcpdump -n -i tun0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun0, link-type RAW (Raw IP), capture size 65535 bytes My current config files server.conf local X.Y.Z.P port 80 proto tcp dev tun ca ca.crt cert server.crt key server.key # This file should be kept secret dh dh1024.pem server 10.8.0.0 255.255.255.0 push "redirect-gateway def1 bypass-dhcp" keepalive 10 120 comp-lzo persist-key persist-tun persist-local-ip status openvpn-status.log verb 3 client.conf client dev tun proto tcp remote MYHOST..amazonaws.com 80 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key ns-cert-type server comp-lzo verb 3

• Is there a monitoring software suite that will alert me if it has received no activity in a time period?

  - by matt b

  This might be a very basic question, but I am not very familiar with the exact features of Nagios versus Munin versus other monitoring tools. Let's say we have a process that needs to run daily for some very important infrastructure reasons. We've had cases where the process did not run or was otherwise down for a number of days before anyone noticed. I'd like to set up a system that will enable me to easily know when the daily run did not take place for some reason. I can set up this process to send an email on every successful run (or every failed run), but I do not trust that the people receiving this email would notice an absence of an "I'm OK" message. What I am envisioning is some type of "tripwire" service which this V.I.P. (very-important-process) can send a status message to each time it runs, whether successfully or not; and if the "tripwire" service has not received any word from the VIP within a configurable amount of time, it can then send an alert to someone. (The difference between what I envision and the first approach I outlined is a service that sends a message only in abnormal conditions, rather than a service that sends messages each day that the status is normal/OK). Can Nagios be set up to send an alert like this, if it has not heard from a certain service/device/process in N days? Is there another tool out there which does have this feature?

• Window too big to fit the screen!

  - by syockit

  I'm using Windows 7 on a 8.9' monitor with 1280x768 screen resolution. Using the might of arithmetics, I'm able to determine that my dpi (actually ppi) should be 167. Win7 is really helpful in that it doesn't have to restart to apply new dpi settings, unlike its predecessors (though I'd rather it applies straight away). The problem with small monitors in Windows is that when you come across windows too big to fit the screen, you can't move the title bar far above it. In X window managers I used in the past, you could alt-drag the window to anywhere you want, but in Windows, even if you alt-space and select move, it will automatically push the window back until the title bar is visible. I'm looking for a solution that either: allows me to move window freely without regard to titlebar visibility, or attach a scrollbar to existing window, or EDIT: create virtual desktops that allow me to span windows over 2 desktops, or EDIT 2: allow me to set larger virtual resolution, then pan & scan. EDIT 3: I found some progs that might do some of the above: 1) AltDrag allows me to drag, resize using alt and left/right mouse button. Neat! Best solution so far. 2) GiMeSpace Desktop Extender is supposed to allow me to scroll desktop. Didn't work. The other new version, GiMeSpace Ultimate Taskbar worked, but it destroys my Superbar, replacing it with its map.

• Is there any reason this cronjob would fail in cron, but not on the command line?

  - by Treffynnon

  I have written a little one liner that will email me when a list of files changes - I used sha512 to generate a list of hashes and then periodically check that those hashes still match. */5 * * * * /usr/bin/sha512sum --status -c /sha512.sumlist && echo "Success" > /dev/null || echo "Check robots.txt and index.html in /var/www as staging sites are now potentially exposed to the world and the damned googlebot" | /usr/bin/mail -s "Default staging server files have changed" [email protected] It works fine on the command line with: /usr/bin/sha512sum --status -c /sha512.sumlist && echo "Success" > /dev/null || echo "Check robots.txt and index.html in /var/www as staging sites are now potentially exposed to the world and the damned googlebot" | /usr/bin/mail -s "Default staging server files have changed" [email protected] As soon as I run it as a cronjob though it emails every time it runs with the failure message instead of only when the sha512sum check should fail. Is there something silly I have missed in a rush? I forgot to mention that I am running an Ubuntu machine.

• Almost All Logical Volumes Disappeared - Recovery?

  - by Alex

  We had a hard disc crash of one of two hard discs in a software raid with a LVM on top. The server is running Citrix xenserver. On the hard disk which is still intact, the volume group gets detected well, but only one LV is left. (some hashes replaced by "x") # lvdisplay --- Logical volume --- LV Name /dev/VG_XenStorage-x-x-x-x-408b91acdcae/MGT VG Name VG_XenStorage-x-x-x-x-408b91acdcae LV UUID x-x-x-x-x-x-vQmZ6C LV Write Access read/write LV Status available # open 0 LV Size 4.00 MiB Current LE 1 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0 root@rescue ~ # vgdisplay --- Volume group --- VG Name VG_XenStorage-x-x-x-x-408b91acdcae System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 4 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 698.62 GiB PE Size 4.00 MiB Total PE 178848 Alloc PE / Size 1 / 4.00 MiB Free PE / Size 178847 / 698.62 GiB VG UUID x-x-x-x-x-x-53w0kL I could understand if a full physical volume is lost - but why only the logical volumes? Is there any explanation for this? Is there any way to recover the logical volumes? EDIT We are here in a rescue system. The problem is that the whole server does not boot (GRUB error 22) What we are trying to do is to access the root filesystem. But everything was in the LVM. We have only this: (parted) print Model: ATA SAMSUNG HD753LJ (scsi) Disk /dev/sdb: 750GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 750GB 750GB primary boot, lvm And this 750GB LVM volume is exactly what we see on top.

• Removing HttpModule for specific path in ASP.NET / IIS 7 application?

  - by soccerdad

  Most succinctly, my question is whether an ASP.NET 4.0 app running under IIS 7 integrated mode should be able to honor this portion of my Web.config file: <location path="auth/windows"> <system.webServer> <modules> <remove name="FormsAuthentication"/> </modules> </system.webServer> </location> I'm experimenting with mixed mode authentication (Windows and Forms). Using IIS Manager, I've disabled Anonymous authentication to auth/windows/winauth.aspx, which is within the location path above. I have Failed Request Tracing set up to trace various HTTP status codes, including 302s. When I request the winauth.aspx page, a 302 HTTP status code is returned. If I look at the request trace, I can see that a 401 (unauthorized) was originally generated by the AnonymousAuthenticationModule. However, the FormsAuthenticationModule converts that to a 302, which is what the browser sees. So it seems as though my attempt to remove that module from the pipeline for pages in that path isn't working. But I'm not seeing any complaints anywhere (event viewer, yellow pages of death, etc.) that would indicate it's an invalid configuration. I want the 401 returned to the browser, which presumably would include an appropriate WWW-Authenticate header. A few other points: a) I do have <authentication mode="Forms"> in my Web.config, and that is what the 302 redirects to; b) I got the "name" of the module I'm trying to remove from the inetserv\config\applicationHost.config file; c) I have this element in my Web.config file: <modules runAllManagedModulesForAllRequests="false">; d) I tried a <location> element for the path in which I set the authentication mode to "None", but that gave a yellow exception page that the property can't be set below the application level. Anyone had any luck removing modules in this fashion?

• zfs pool error, how to determine which drive failed in the past

  - by Kendrick

  I had been copying data from my pool so that I could rebuild it with a different version so that I could go away from solaris 11 and to one that is portable between freebsd/openindia etc. it was copying at 20mb a sec the other day which is about all my desktop drive can handle writing from the network. suddently lastnight it went down to 1.4mb i ran zpool status today and got this. pool: store state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scan: none requested config: NAME STATE READ WRITE CKSUM store ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c8t3d0p0 ONLINE 0 0 2 c8t4d0p0 ONLINE 0 0 10 c8t2d0p0 ONLINE 0 0 0 it is currently a 3 x1tb drive array. what tools would best be used to determine what the error was and which drive is failing. per the admin doc The second section of the configuration output displays error statistics. These errors are divided into three categories: READ – I/O errors occurred while issuing a read request. WRITE – I/O errors occurred while issuing a write request. CKSUM – Checksum errors. The device returned corrupted data as the result of a read request. it was saying low counts could be any thing from a power flux to a disk event but gave no suggestions as to what tools to check and determine with.

• upstart scripts: run a task after networking goes up

  - by The Journeyman geek

  I'm working on moving my current server setup to newer hardware, and migrating from ubuntu karmic koala to lucid lynx. Currently i'm using gw6c (compiled from the gogo6 website, as opposed to the version from the repositories) to get ipv6 access for my systems. On the karmic koala system, i used simple init.d script to get the ipv6 client started #! /bin/sh /usr/local/gw6c/bin/gw6c -f /usr/local/gw6c/bin/gw6c.conf I figured since this runs at any runlevel, it should translate to respawn console none start on startup stop on shutdown script exec /usr/local/gw6c/bin/gw6c -f /usr/local/gw6c/bin/gw6c.conf emit free6_ipv6_started end script this works fine started from initctrl, but it apparently fails to start when it boots. - its status being stop/waiting. It works fine (and respawns) when started otherwise.Any ideas on where i'm going wrong, and what would be the appropriate 'start on' arguement? EDIT: the exact error is 'init: gw6c main process (xxx) ended with status 8' followed by the process respawning , with xxx being a PID i suspect. I'm also half suspecting this is cause gw6c starts before networking does, and i need my eth0 up before gw6c is

• Upstart multiple instances of service not working.

  - by Dax

  I started playing with MongoDB on Lucid. Now I would like to run a DB and Config server on the same box. They both use the same binary to launch, but with different config files and running on different ports. All directories for log and lib is split so one goes to mongodb and the other to mongoconf. Each process can be started without any problems on their own. start mongodb stop mongodb start mongoconf stop mongoconf But if I try to start both, the second one would just start and exit. Using 'initctl log-priority debug' I got the following in the logs. Jan 6 12:44:12 mongo4 init: event_finished: Finished started event Jan 6 12:44:12 mongo4 init: job_process_handler: Ignored event 1 (1) for process 5690 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) main process (5690) terminated with status 1 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) goal changed from start to stop Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) state changed from running to stopping man 5 init shows that you can use instance names to differentiate the two. I tried using 'instance mongoconf' in the on upstart script and 'instance mongodb' in the other one, and it still fails. I can manually start the other process, so there is definitely no conflicts on port numbers or directories. Any ideas on what to try or how to get output on why it is 'terminated with status 1'? Thanx

• Shell replacement for kiosk environment with desktop icons

  - by tuesprem

  I have to deploy around 80 touch-screen terminals for my company. We're going to run several Windows applications on those terminals and they'll be operated by touch input only. I basically want those machines to run in a kiosk mode, so employees won't be able to launch any programs than the ones they're supposed to (also, this will hide the task bar/start menu, which will give it a much nicer, corporate look). There's usually one app that should automatically launch on startup and other apps that can be launched from the desktop. I've tried to accomplish this (under Windows 7 Pro) with a custom shell replacement. This removes the task bar/start menu like I described earlier. I used an AutoHotKey script for this, because it's easy to, for instance, define hotkeys so admins will still be able to launch stuff like Windows Explorer (okay, I know I could just launch it from the task manager [Ctrl+Shift+Esc] but I'm considering locking that as well). So far so good. Some problems though: No desktop icons. Needed to launch apps from the desktop. No wallpaper. Required for CI. Is there any way around this? I wouldn't mind using another shell replacement, as long as it's reasonably lightweight. I'd love to get the wallpaper and desktop icons to show with something like AutoHotKey though. Thanks!

  Whenever I enable TCP/IP connections on my SQL Server Express 2008 database server running on Windows XP SP3, I cannot restart the service, it simply states "The request failed or did respond in a timely fashion". Any suggestions of what I may have configured incorrectly? [update] Here is the applicable part of the Error Log: MSSQL$SQLEXPRESS Server failed to list on 'any' 3060. Error: 0x2747. To proceed, notify you system administrator. MSSQL$SQLEXPRESS TDSSNIClient initialization failed with error 0x2747, status code 0xa. Reason: Unable to initialize the TCP/IP listener. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.

• Windows 7 clean install becomes corrupt after reboot (repeated many fresh installs)

  - by pjotr_dolphin

  My laptop keeps crashing on boot after clean Windows 7 install. Ok, here is the story, and some fact. Computer: Samsung NP900X3C-A04HK (256GB SSD, 8GB RAM) OS to install: Windows 7 Ultimate SP1 (not from Samsung, own fresh Win) I purchased this laptop about a year ago, never booted it into the Windows Home that was installed on it, installed directly Ubuntu on the machine. Full disc encryption was the selected install, so of course it wiped the complete disc (including Samsung Recovery Partition). After some time, I felt like going back to Windows, as Windows 7 is actually quite nice. So I went to buy a fresh Windows 7Ultimate with SP1. Now to the tricky part. Windows installs perfectly, and after installing all Windows updates, drivers from Samsung, software I need, it is time for shutting it down and go to bed. Starting it up again, and it is not booting, these are the type of errors I have gotten so far (fresh installed it more then a dozen times now, and tried different suggestions from threads on the net). Windows failed to start... Status: 0xc000000f Info: The boot selection failed because a required device is inaccessible. File: /boot/bcd Status: 0xc000000f Info: an error occurred while attempting to read the boot configuration data. And some other errors, not all the same. Not memory of this. I have run different disc checks, and all says my SSD is in perfect shape. Note: Soft reboots from Windows menu works, never gets corrupted. But if I Shutdown and then start it up again, this is when it happens. Can someone help me not get back to Ubunut? What can be the cause, and how can it be fixed so I do not get there problems again?

• Invisible Apache redirect

  - by Guilhem Soulas

  I would like subdomain.mydomain.com to invisibly redirect to https://[myServerIP]:2083. (There is an SSL issue here). So far I managed to do it, but the redirection is visible and I don't want it: RewriteCond %{HTTPS} off RewriteCond %{HTTP_HOST} ^subdomain.\.mydomain\.com$ RewriteRule ^ https://[myServerIP]:2083/ Would it be a way to achieve the same redirection while maintaining permanently my beautiful "subdomain.mydomain.com" in the address bar? EDIT with the ProxyPass directive: I tried some variations with ProxyPass but it will still change the URL in the address bar: ServerName subdomain.mydomain.com <Location /> ProxyPass https://[myServerIP]:2083/ ProxyPassReverse https://[myServerIP]:2083/ </Location> RewriteCond %{HTTPS} off RewriteCond %{HTTP_HOST} ^subdomain\.mydomain\.com$ RewriteRule ^ https://[myServerIP]:2083/ EDIT2: It still doesn't work: #non SSL ServerName subdomain.mydomain.com #SSL! <Location /> ProxyPass https://[myServerIP]:2083/ ProxyPassReverse https://[myServerIP]:2083/ </Location> EDIT3: It now works using the SSLProxyEngine directive: SSLProxyEngine on ServerName subdomain.mydomain.com <Location /> ProxyPass https://[myServerIP]:2083/ ProxyPassReverse https://[myServerIP]:2083/ </Location> I can now access my login interface (cPanel). However, once I'm logged in it doesn't redirect to the next page subdomain.mydomain.com/cpsess5850710203/.

• No "New Folder" button in windows 7

  - by user1125620

  My sibling's laptop is running windows 7 x64. The torrents folder in Documents doesn't show the New Folder button. ctrl+shift+n doesn't work either. I tried EVERYTHING here: Can't create new folder from anywhere in Windows 7 ..but nothing worked. As with the OP there, running the .reg file brings an error that says something about not being able to change the registry value while something is using it. I removed one entry at a time in the .reg file until I narrowed down the ones that were causing the problem, which were in HKEY_CLASSES_ROOT/CLSID. The only different reg value, however, was in HKEY_CLASSES_ROOT\CLSID{11dbb47c-a525-400b-9e80-a54615a090c0}\InProcServer32, for which the default value was %SystemRoot%\system32\explorerframe.dll and the value trying to be set ExplorerFrame.dll. I'm on windows 7 32bit and that's the same value I have for the entry, so I doubt that's it. The only thing I think is slightly off is that there is a user group with a strange name that only has execute and read access, and I can't grant it full control. Every time I try, it acts as if it works, but doesn't change it. I tried booting into safe mode and changing it, but it did the same thing. It is the folder where utorrent puts any new downloads, so it's possible utorrent did something, though that's never happened to me before. edit: I had renamed the folder to something else to avoid the problem, and then went onto my own computer to try to figure out what was wrong (I personally don't like using the touchpad on laptops). While searching, my sibling starting watching a movie. I minimized the movie and saw that the same thing had happened to the folder I renamed. Also changed was the file layout. It showed the different days and the files modified on those days. So, I was able to fix it by doing: Clicking Organize Layout Menu Bar On the menu bar clicking View Arrange By Folder

• Strange focus bug in Firefox (chrome vs content)

  - by Marius

  Here is a strange bug I'm experiencing in Firefox: I can only use either the chrome, or the content, not both at the same time! For example, I can click on tabs and the toolbar icons, focus the search bar and write in it as well as the address bar, but if I try to click on anything in the content (eg a link or a textfield to write something), then nothing happens. The mouse pointer doesn't change either, it just stays a pointer when I hover over things, and the links I hover don't react either. But if I alt-tab to another program (or click on it in the taskbar), then back to Firefox, then I can use the area that I click on. So if I click somewhere on the webpage to get focus back to Firefox, then I can click on links and write things (like this text), but I cannot click on tabs or refresh or anything else in the chrome. I can't even click on the minimize, restore and close icons! To get focus back on the chrome I have to alt-tab to another program, and then click on the chrome to get back to Firefox to be able to use the chrome again. I've tried closing and starting it again, but the bug is still there. I have experienced this before, but I don't remember what I did to fix it. This bug seems to occur sometimes when I wake up the computer from standby, but I leave by computer in standby all the time, so that is not the only factor.

• IE8 page reload hangs

  - by Rod

  When a 7mb HTM file is first opened (by clicking on the file icon or using Open With), both IE8 and Firefox display this browser file quickly. After the file is closed, Firefox will reopen this file quickly, but IE8 appears to hang during the reopen. Clearing the IE cache does not help. However, IE will reopen the file quickly again only if the File/Open/Browse feature of the menu bar is used (clicking on the file icon can be used only once between computer reboots). Testing suggests that the problem relates to the number of HTML hyperlinks pointing to another part of the file. There are many hyperlinks, but they are not a problem during the first load of the document (between computer reboots). What needs to be fixed to avoid use of the workaround? Using Windows XP SP3 Update 6/23/12 - Controlled testing shows that the number of hyperlinks is not the problem. The way this large file is opened is the difference: 1) from the IE menu bar, File/Open/Browse is consistent and fast (but not as fast as FF). 2) clicking on the file name in the folder (even when IE is the default program for this file type) causes a much delayed load of the file. Creating a smaller file demonstrates the delayed load, but verifies that the load eventually occurs.

• Windows XP to remote server 2008 R2 shares - awful response times

  - by nick3216

  I have a network infrastructure of Windows XP clients (a mix of XP and 64-bit XP), that are accessing a network share on a Windows 2008 R2 server. Whenever users type the address of a folder into the address bar of Windows Explorer it's as snappy at determining the contents of the current folder and presenting them to you in the address bar as if you're working on a local drive. But if you open one of the subfolders users get the animated red torch and 'Searching for items...' dialog, typically for 45 seconds. Similarly when using the open folder dialog to try and select a subfolder on this share it takes, on average, 45 seconds for the dialog to expand each node and show the subfolders of each node. Also, while the Explorer instance accsesing the network share is running slowly users notice that the performance of all other Explorer windows suffers. So while Explorer is searching for files on the network share they can't switch to another task and navigate around their local drive using Explorer because it's now as slow as a dead dog at accessing anything. Are there any settings we can change which will improve the performance accessing network shares?

• Python script is exiting with no output and I have no idea why

  - by Adam Tuttle

  I'm attempting to debug a Subversion post-commit hook that calls some python scripts. What I've been able to determine so far is that when I run post-commit.bat manually (I've created a wrapper for it to make it easier) everything succeeds, but when SVN runs it one particular step doesn't work. We're using CollabNet SVNServe, which I know from the documentation removes all environment variables. This had caused some problems earlier, but shouldn't be an issue now. Before Subversion calls a hook script, it removes all variables - including $PATH on Unix, and %PATH% on Windows - from the environment. Therefore, your script can only run another program if you spell out that program's absolute name. The relevant portion of post-commit.bat is: echo -------------------------- >> c:\svn-repos\company\hooks\svn2ftp.out.log set SITENAME=staging set SVNPATH=branches/staging/wwwroot/ "C:\Python3\python.exe" C:\svn-repos\company\hooks\svn2ftp.py ^ --svnUser="svnusername" ^ --svnPass="svnpassword" ^ --ftp-user=ftpuser ^ --ftp-password=ftppassword ^ --ftp-remote-dir=/ ^ --access-url=svn://10.0.100.6/company ^ --status-file="C:\svn-repos\company\hooks\svn2ftp-%SITENAME%.dat" ^ --project-directory=%SVNPATH% "staging.company.com" %1 %2 >> c:\svn-repos\company\hooks\svn2ftp.out.log echo -------------------------- >> c:\svn-repos\company\hooks\svn2ftp.out.log When I run post-commit.bat manually, for example: post-commit c:\svn-repos\company 12345, I see output like the following in svn2ftp.out.log: -------------------------- args1: c:\svn-repos\company args0: staging.company.com abspath: c:\svn-repos\company project_dir: branches/staging/wwwroot/ local_repos_path: c:\svn-repos\company getting youngest revision... done, up-to-date -------------------------- However, when I commit something to the repo and it runs automatically, the output is: -------------------------- -------------------------- svn2ftp.py is a bit long, so I apologize but here goes. I'll have some notes/disclaimers about its contents below it. #!/usr/bin/env python """Usage: svn2ftp.py [OPTION...] FTP-HOST REPOS-PATH Upload to FTP-HOST changes committed to the Subversion repository at REPOS-PATH. Uses svn diff --summarize to only propagate the changed files Options: -?, --help Show this help message. -u, --ftp-user=USER The username for the FTP server. Default: 'anonymous' -p, --ftp-password=P The password for the FTP server. Default: '@' -P, --ftp-port=X Port number for the FTP server. Default: 21 -r, --ftp-remote-dir=DIR The remote directory that is expected to resemble the repository project directory -a, --access-url=URL This is the URL that should be used when trying to SVN export files so that they can be uploaded to the FTP server -s, --status-file=PATH Required. This script needs to store the last successful revision that was transferred to the server. PATH is the location of this file. -d, --project-directory=DIR If the project you are interested in sending to the FTP server is not under the root of the repository (/), set this parameter. Example: -d 'project1/trunk/' This should NOT start with a '/'. 2008.5.2 CKS Fixed possible Windows-related bug with tempfile, where the script didn't have permission to write to the tempfile. Replaced this with a open()-created file created in the CWD. 2008.5.13 CKS Added error logging. Added exception for file-not-found errors when deleting files. 2008.5.14 CKS Change file open to 'rb' mode, to prevent Python's universal newline support from stripping CR characters, causing later comparisons between FTP and SVN to report changes.

The body of get_login is in a try block because I was getting strange errors saying there was an unhandled exception in callback_get_login. Never figured out why, but it seems fine now. Let sleeping dogs lie, right? The username and password for get_login are currently hard-coded (but correct) just to eliminate variables and try to change as little as possible at once. (I added the svnuser and svnpass arguments to the existing argument parsing.) So that's where I am. I can't figure out why on earth it's not printing anything into svn2ftp.out.log. If you're wondering, the output for one of these failed attempts in svn2ftp.debug.log is: 2012-09-06 15:18:12,496 INFO svnftp.start 2012-09-06 15:18:12,496 INFO svnftp.done And it's no different on a successful run. So there's nothing useful being logged. I'm lost. I've gone way down the rabbit hole on this one, and don't know where to go from here. Any ideas?
