• apache2 + mod_fastcgi + suexec + php5.2 = unstable on high load

  I am hosting several (~30) different sites on one server with apache2+fastcgi+suexec+php5. Sites have different loads and different execution times of their scripts (some of them process request for 5-7 seconds, some <1sek). Sometimes when single site receives very high load (all php instances of this site are created and used) - whole apache server hangs. Apache (worker mpm) creates new processes up to the upper limit. It looks like it is starting to queue ALL new request for EVERY site, not only the one that has high load and quickly achieves process limits... restart of apache solves the problem... config: FastCgiConfig -singleThreshold 1 -multiThreshold 10 -listen-queue-depth 30 -maxProcesses 80 -maxClassProcesses 12 -idle-timeout 30 -pass-header HTTP_AUTHORIZATION -pass-header If-Modified-Since -pass-header If-None-Match (earlier have default -listen-queue-depth = 100, but it didn't change anything...) Any suggestions? Another question - how is implemented this listen queue? is it one queue for whole apache, or unique queue for every defined php apllication (suexec site)? I would like to achieve something like this: when one site receives high load and its queue is full - server bounces next request, but only for this one site.. Other sites should work properly...

• Simultanious process mysteriously ending

  - by Matt

  I'm trying to run a large air quality model, written in FORTRAN, setup with bash scripts, and run in a work queue (slurm.) The first part of the modeling is to run an "entry" model, this runs with MPI in the work queue but only on one process. At one point in the logs, there's a mysterious FORTRAN STOP, and then later the model fails because something wasn't set up properly. This FORTRAN STOP isn't from the main process, which continues running. This is a huge model, but as far as I know there should not be any other processes running at the same time. It consistently fails at the exact same spot. (I can move it by adding debug, but the debug is in the main process) How can I determine what this process is? I've tried added a call to strace -feprocess $SHELL in the run script, but I'm new to this, so if it has offered any info, I haven't been able to use it yet. The is no trace output around the FORTRAN STOP. The whole process occurs so fast that I can't seem to observe it by using ps. Is there a way I can somehow monitor all the processes being initiated from the time the work queue starts? Or some other way I can figure out what is failing? This is running on CentOS 6.4, with Slurm, compiled with PGI 13.

• PHPMyAdmin: "General relation features: Disabled"

  - by Simón

  I've been looking around for something like this for a while, and I've found some tips on similar issues, but not exactly the same. I really don't know what to do. I downloaded and installed WAMP, and I have a MySQL and PHPMyAdmin setup according to common indications that can be found everywhere (securing MySQL root account, etc.). When I log into PHPMyAdmin (either as root or as pma), I see the following message at the bottom of the page: The additional features for working with linked tables have been deactivated. To find out why click here. And when following the link, got a page with the following: Server: localhost $cfg['Servers'][$i]['pmadb'] ... OK $cfg['Servers'][$i]['relation'] ... OK General relation features: Disabled $cfg['Servers'][$i]['table_info'] ... OK Display Features: Disabled $cfg['Servers'][$i]['table_coords'] ... OK $cfg['Servers'][$i]['pdf_pages'] ... OK Creation of PDFs: Disabled $cfg['Servers'][$i]['column_info'] ... OK Displaying Column Comments: Disabled Bookmarked SQL query: Disabled Browser transformation: Disabled $cfg['Servers'][$i]['history'] ... OK SQL history: Disabled $cfg['Servers'][$i]['designer_coords'] ... OK Designer: Disabled Somebody please explain to me, why the heck if all settings are "OK" the features remain "Disabled"? Note: at first all the settings were "not OK" and I managed to add the settings to config.inc.php, and then created the tables using scripts/create_tables.php. Of course I have already tried restarting the server or clearing the browser cache (several times, so I am sure the problem comes elsewhere).

• Domain names timing out after VPS IP change

  - by Fourjays

  I rent a CentOS 5 VPS from a UK-based provider, with DirectAdmin also installed. On Thursday night, they carried out planned maintenance to changed the two IPs I had been assigned to two new ones. On Friday, after the change had taken place, I updated my domain name records to reflect the IP change. Since then, all of the domains pointing to the VPS are timing out. Additionally, DirectAdmin was also not responding, but was was resolved by running the ipswap scripts as found in the DirectAdmin knowledgebase. It did not fix my domains though. I have contacted the VPS provider but I have been waiting for a response for some time now. I have checked again, and again, and all the IPs referenced in DirectAdmin are correct. If I go to the server IP in my browser it responds with "Apache is functioning normally." Email accounts on the server are also functioning correctly. But if I access a domain itself, it times out. Running a ping and a DNS look-up, I can confirm the nameserver IPs are correct. If I run a trace route it reaches an IP that is similar to my VPS IPs (last 2 blocks are different) before timing out (it never shows my server IP). I am relatively new to VPS management so don't have a vast wealth of experience with troubleshooting problems on them. I have checked all of the httpd configuration files, which don't seem to have any IP references in them at all. Looking in the Apache error logs, what errors there are do not coincide with times I have tried to access the site. Is this issue at my provider's end? Is there anything else I can check or test, to rule out post-IP-change problems with my server configuration? It was all running fine prior to the IP change.

• Using mod_rewrite to mask /cgi-bin/abc as /def

  - by Alois Mahdal

  I have a seemingly easy task, but somehow I just can't get it to work: Some interesting lines from my httpd.conf: ... DocumentRoot "D:/opt/apache/htdocs" ... ScriptAlias /cgi-bin/ "D:/opt/apache/cgi-bin/" ... <Directory "D:/opt/apache/htdocs"> Options Indexes FollowSymLinks ExecCGI AllowOverride None Order allow,deny Allow from all </Directory> <Directory "D:/opt/apache/cgi-bin/"> AllowOverride None Options ExecCGI Order allow,deny Allow from all </Directory> (I know it's dumb but it's only a testing machine :D.) Now, I have d:\opt\apache\cgi-bin\expired.pl and I expect GET /licensecheck.php?code=123456. And I wish to fake client into thinking it speaks with /licensecheck.php, but actually return data by \expired.pl. What I tried was setting following at the end of http.conf: RewriteEngine on RewriteRule ^/licensecheck.php$ /cgi-bin/expired.pl [T=application/x-httpd-cgi,L] ...but it keeps 404-ing me, looking for cgi-bin directory (not cgi-bin\expired.pl) in my DocumentRoot! [error] [client 127.0.0.1] script not found or unable to stat: D:/opt/apache/htdocs/cgi-bin /cgi-bin/expired.pl and all other scripts in /cgi-bin/ work as expected, Only way I could make it work was actually putting the \expired.pl to DocumentRoot, but I don't want this, I want my cgi-bin neatly separated :)

• Replicated MongoDB server slower than simple shards

  - by displayName

  I tried to compare the performance of a sharded configuration against a sharded and replicated configuration. The sharded configuration consists of 8 shards each running on three different machines thereby constituting a total of 24 shards. All 8 of these shards run in the same partition on each machine. The sharded and replicated version is 8 shards again just like plain sharding, and all 8 mongods run on the same partition in each machine. But apart from this, each of these three machine now run additional 16 threads on another partition which serve as the secondary for the 8 mongods running on other machines. This is the way I prepared a sharded and replicated configuration with data chunks having replication factor of 3. Important point to note is that once the data has been loaded, it is not modified. So after primary and secondaries have synchronized then it doesn't matter which one i read from. To run the queries, I use an entirely different machine (let's call it config) which runs mongos and this machine's only purpose is to receive queries and run them on the cluster. Contrary to my expectations, plain sharding of 8 threads on each machine (total = 3 * 8 = 24) is performing better for queries than the sharded + replicated configuration. I have a script written to perform the query. So in order to time the scripts, I use time ./testScript and see the result. I tried changing the reading preference for replicated cluster by logging to mongo of config and run db.getMongo().setReadPref('secondary') and then exit the shell and run the queries like time ./testScript. The questions are: Where am i going wrong in the replication? Why is it slower than its plain sharding version? Does the db.getMongo().ReadPref('secondary') persist when i leave the shell and try to perform the query? All the four machines are running Linux and i have already increased the ulimit -n to 2048 from initial value of 1024 to allow more connections. The collections are properly distributed and all the mongods have equal number of chunks. Goes without saying that indices in both configurations are the same.

• Shared files folder in Amazon Elastic Beanstalk environment

  - by por

  I'm working on a Drupal application, which is planned to be hosted in Amazon Elastic Beanstalk environment. Basically, Elastic Beanstalk enables the application to scale automatically by starting additional web server instances based on predefined rules. The shared database is running on an Amazon RDS instance, which all instances can access properly. The problem is the shared files folder (sites/default/files). We're using git as SCM, and with it we're able to deploy new versions by executing $ git aws.push. In the background Elastic Beanstalk automatically deletes ($ rm -rf) the current codebase from all servers running in the environment, and deploys the new version. The plan was to use S3 (s3fs) for shared files in the staging environment, and NFS in the production environment. We've managed to set up the environment to the extent where the shared files folder is mounted after a reboot properly. But... The Problem is that, in this setup, the deployment of new versions on running instances fail because $ rm -rf can't remove the mounted directory, and as result, the entire environment goes down and we need restart the environment, which isn't really an elegant solution. Question #1 is that what would be the proper way to manage shared files in this kind of deployment? Are you running such an environment? How did you solve the problem? By looking at Elastic Beanstalk Hostmanager code (Ruby) there seems be a way to hook our functionality (unmount if mounted in pre-deploy and mount in post-deploy) into Hostmanager (/opt/hostmanager/srv/lib/elasticbeanstalk/hostmanager/applications/phpapplication.rb) but the scripts defined in the file (i.e. /tmp/php_post_deploy_app.sh) don't seem to be working. That might be because our Ruby skills are non-existent. Question #2 is that did you manage to hook your functionality in Hostmanager in a portable way (i.e. by not changing the core Hostmanager files)?

• Problem restoring from tar backup: why are there /dev/disk/by-id/ symlinks and how can I avoid them?

  - by SK.

  Hello, I'm trying to make a bare-bone backup system with the most basic tools available on openSUSE 11.3 (in this case: bash, fdisk, tar & grub legacy) Here's the workflow for my scripts: backup.sh: (Run from external system, e.g. LiveCD) make an fdisk script ($fscript) from fdisk -l's output [works] mount the partitions from the system's fstab [works] tar the crucial stuff in file.tgz [works] restore.sh: (Run from external system, e.g. LiveCD) run fdisk $dest < $fscript to restore partitioning [works] format and mount partitions from system's fstab [fails] extract from file.tgz [works when mounting manually] restore grub [fails] I have recently noticed that openSUSE (though I'm sure it has nothing to do with the distro) has different output in /etc/fstab and /boot/grub/menu.lst, more precisely the partition name is for example "/dev/disk/by-id/numbers-brandname-morenumbers-part2" instead of "/dev/sda2" -- but it basically is a simple symlink. My questions about this: what is the point of such symlinks, especially if we're restoring on a different disk? is there a way to cleanly prevent the creation of those symlinks and use the "true" /dev/sdx everywhere instead? if the previous is no, do you know a way to replace those symlinks on the fly in a text file? I tried this script but only works if the file starts with the symlink description (case of fstab, not menu.lst): ### search and replace /dev/disk/by-id/... to /dev/sdx while read oldVolume rest; do # get first element, ignore rest of line if [[ "$oldVolume" =~ ^/dev/disk/by-id/.*(-part[0-9]*$)? ]]; then newVolume=$(readlink $oldVolume) # replace pointer by pointee, returns "../../sdx" echo /dev/${newVolume##*/} $rest >> TMP # format to "/dev/sdx", write line else echo $oldVolume $rest >> TMP # nothing to do fi done < $file mv -f TMP $file # save changes I've had trouble finding a solution to this on google so I was hoping some of the members here could help me. Thank you.

• Can MS Services for Unix be deployed and accessed from a shared drive?

  - by Ian C.

  I'm interested in experimenting with replacing our dependency on MKS with MS' Sevices for Unix toolset. I was wondering if anyone has any experience with deploying SFU on a shared drive? We like to, wherever possible, host our dev tools on one central NAS and call to the NAS to access the tools instead of rolling stuff out to each and every desktop. I'm not interested in the NFS support or ActiveState Perl. Really, none of the daemon technology is required here. I'm looking for replacements for the coreutils/binutils stuff you find in Linux (and MKS on Windows): sed, awk, csh, bash, grep, ls, find -- the meat-and-potates command line apps that our build and test scripts are built around. If I limit the install to just the Interix GNU Components (and maybe the Remote Connectivity components) will is run nicely from a shared location? To head off some questions: Yes, I've looked at Cygwin. Unfortunately it's performance in our build and test environment is poor. It runs considerably slower than MKS and it's not a direct drop-in replacement for MKS (thanks to its internal pathing and limitations with commands like 'ps'), so it's a tougher sell. Yes, I'm looking at the MinGW offering in parallel to this.

• iptables, blocking large numbers of IP Addresses

  - by Twirrim

  I'm looking to block IP addresses in a relatively automated fashion if they look to be 'screen scraping' content from websites that we host. In the past this was achieved by some ingenious perl scripts and OpenBSD's pf. pf is great in that you can provide it nice tables of IP addresses and it will efficiently handle blocking based on them. However for various reasons (before my time) they made the decision to switch to CentOS. iptables doesn't natively provide the ability to block large numbers of addresses (I'm told it wasn't unusual to be blocking 5000+), and I'm a bit cautious over adding that many rules into an iptable. ipt_recent would be awesome for doing this, plus it provides a lot of flexibility for just severely slowing down access, but there is a bug in the CentOS kernel that is stopping me from using it (reported, but awaiting fix). Using ipset would entail compiling a more up-to-date version of iptables than comes with CentOS which whilst I'm perfectly capable of doing it, I'd rather not do from a patching, security and consistency perspective. Other than those two it looks like nfblock is a reasonable alternative. Is anyone aware of other ways of achieving this? Are my concerns about several thousand IP addresses in iptables as individual rules unfounded?

• Managing an application across multiple servers, or PXE vs cfEngine/Chef/Puppet

  - by matt

  We have an application that is running on a few (5 or so and will grow) boxes. The hardware is identical in all the machines, and ideally the software would be as well. I have been managing them by hand up until now, and don't want to anymore (static ip addresses, disabling all necessary services, installing required packages...) . Can anyone balance the pros and cons of the following options, or suggest something more intelligent? 1: Individually install centos on all the boxes and manage the configs with chef/cfengine/puppet. This would be good, as I have wanted an excuse to learn to use one of applications, but I don't know if this is actually the best solution. 2: Make one box perfect and image it. Serve the image over PXE and whenever I want to make modifications, I can just reboot the boxes from a new image. How do cluster guys normally handle things like having mac addresses in the /etc/sysconfig/network-scripts/ifcfg* files? We use infiniband as well, and it also refuses to start if the hwaddr is wrong. Can these be correctly generated at boot? I'm leaning towards the PXE solution, but I think monitoring with munin or nagios will be a little more complicated with this. Anyone have experience with this type of problem? All the servers have SSDs in them and are fast and powerful. Thanks, matt.

• Setting up Windows network on Xen

  - by samyboy

  I'm trying to install a Windows XP server in a Xen environment. The OS is booting fine. Unfortunately I can't figure out how to set up the network settings. Dom0 is a Debian Lenny currently hosting around 10 Linux virtual servers. Windows tells me I have a "limited connection". It can't get any DHCP response, nor access other hosts in the network Here is the Xen's client config file: kernel = '/usr/lib/xen-3.2-1/boot/hvmloader' builder = 'hvm' memory = '1024' device_model='/usr/lib/xen-3.2-1/bin/qemu-dm' acpi=1 apic=1 pae=1 vcpus=1 name = 'winexchange' # Disks disk = [ 'phy:/dev/wnghosts/exchange-disk,ioemu:hda,w', 'file:/mnt/freespace/ISO/DVD1_Installation.iso,ioemu:hdc:cdrom,r' ] # Networking vif = [ 'mac=00:16:3E:0A:D0:1B, type=ioemu, bridge=xenbr0'] # video stdvga=0 serial='pty' ne2000=0 # Behaviour boot='c' sdl=0 # VNC vfb = [ 'type=vnc' ] vnc=1 vncdisplay=1 vncunused=1 usbdevice='tablet' Server config (/etc/xen/xend-config.sxp) (network-script network-bridge) (network-script network-dummy) (vif-script vif-bridge) (dom0-min-mem 512) (dom0-cpus 0) (vnc-listen '0.0.0.0') Since I use Debian I had to create a link like this: /etc/xen/qemu-ifup - /etc/xen/scripts/qemu-ifup What did I do wrong?

• init.d script runs correctly but process doesn't live when booted fully up

  I have a problem with an init.d script #!/bin/bash ES_HOME="/var/es/current" PID=$(ps ax | grep elasticsearch | grep $ES_HOME | grep -v grep | awk '{print $1}') #echo $PID #exit 0 case "$1" in start) if [ -z "$PID" ]; then echo "Starting Elasticsearch" echo "Starting Elasticsearch" /var/tmp/elasticsearch su -m elasticsearch -c "${ES_HOME}/bin/elasticsearch" exit 0; else echo "Elasticsearch already running" echo "Elasticsearch already running" /var/tmp/elasticsearch exit 0; fi ;; stop) if [ -n "$PID" ]; then echo "Stopping Elasticsearch" kill ${PID} echo "Stopped Elasticsearch" exit 0; else echo "Elasticsearch is not running" exit 0; fi ;; esac The scripts runs just file, as I can see in /var/tmp/elasticsearch a new line is added after every boot, but if I run: /etc/init.d/elasticsearch stop Just after the server is booted, I get "Elasticsearch is not running", ergo somehow the process does not stay alive. My question is why? and what am I doing wrong? Thanks in advance.

• How to check DVD integrity at max read speed of DVD writer

  - by ashishsony

  I need to check the integrity of burned DVDs so that I can be sure about my backed-up data. I use DL-DVDs to take the backup. Earlier I used VSO Inspector software for the same but the day I switched to DL-DVDs the VSO Inspector gives me errors upon checking. I think the errors are because the switching of layer writing involves some dummy data somewhere. Secondly, it's damned slow for checking. I believe if there is a utility that can read all files (not the disk surface) and report if some files are unreadable would do the job. But it should be quick! Nobody wants to sit for disk checking for 3-4 hours after a quick 30 min data burn! I am looking for such a utility on Windows or Linux. Even scripts (python, etc) will do. I just want to be assured that the data is safe. Can someone help me in this? Thanks.

• Any non-custom way to manage iptables with fail2ban and libvirt+kvm?

  - by Peter Hansen

  I have an Ubuntu 9.04 server running libvirt/kvm and fail2ban (for SSH attacks). Both libvirt and fail2ban integrate with iptables in different ways. Libvirt uses (I think) some XML config and during startup (?) configures forwarding to the VM subnet. Fail2ban installs a custom chain (probably at init) and periodically modifies it to ban/unban probable attackers. I also need to install my own rules to forward various ports to servers running in VMs and on other machines, and set up rudimentary security (e.g. drop all INPUT traffic except the few ports I want open), and of course I'd like the ability to add/remove rules safely without restarting. It seems to me iptables is a powerful tool that's sorely lacking some sort of standardized way of juggling all this stuff. Every project, and every sysadmin, seems to do it differently! (And I think there's lots of "cargo cult" admin going on here, with people cloning crude approaches like "use iptables-save like so".) Short of figuring out the gory details of exactly how both of these (and potentially other) tools manipulate the netfilter tables, and developing my own scripts or just manually executing iptables commands, is there any way to safely work with iptables while not breaking the functionality of these other tools? Any nascent standards or projects defined to bring sanity to this area? Even a helpful web page I missed that might cover at least these two packages together?

• Estimating compressed file size using a list parameter

  - by Sai

  I am currently compressing a list of files from a directory in the following format: tar -cvjf test_1.tar.gz -T test_1.lst --no-recursion The above command will compress only those files mentioned in the list. I am doing this because this list is generated such that it fits a DVD. However, during compression the compression rate decreases the estimated file size and there is abundant space left in the DVD. This is something like a Knapsack algorithm. I would like to estimate the compressed file size and add some more files to the list. I found that it is possible to estimate file size using the following command: tar -cjf - Folder/ | wc -c This command does not take a list parameter. Is there a way to estimate compressed file size? I am also looking into options like perl scripts etc. Edit: I think I should provide more information since I have been doing a lot of web search. I came across a perl script(Link)that sort of emulates the Knapsack algorithm. The current problem with the above mentioned script is that it splits the files in their original state. When I compress the files after splitting them, there are opportunities for adding more files which I consider to be inefficient. There are 2 ways I could resolve the inefficiency: a) Compress individual files and save them in a directory using a script. The compressed file could provide a best estimate. I could generate a script using a folder of compressed files and use them on the uncompressed ones. b) Check whether the compressed file's size is less than the required size. If so, I should keep adding files until I meet the requirement. However, the addition of new files to the compressed file is an optimization problem by itself.

• finding the best network latency between two countries

  - by Yoav Aner

  I know there are many tools to test for bandwidth and latency, but they all rely on having at least one host from which you can run those tests. I wonder whether there's an online source or some other way to guestimate the latency or speed between two countries (in general). For example, would a customer in Japan get lower latency if the server is located in Singapore or Australia? Is a user in India likely to get higher download speed from a server in the UK or in the US? Are there any online resources or some clever ways to answer those questions with a reasonable degree of accuracy? [UPDATE]: Thanks for the great suggestions from Raffael Luthiger. I didn't know about those looking glass servers. The submarine cable maps were also really cool to discover (Thanks to Jesper Mortensen). Also seems really wise if I could ask those network professional in the area for their experience, but obviously I don't have access to those. At least some of them are on SF :) However, I'm still a little unsure how to combine those resources to give me some measurements. This is the information I have: Two countries (A,B). I do have IP addresses of customers in country A (I can obtain those from the web server log files for example). Presumably I can find some looking glass servers in country B and run a trace to those IPs. What's the best measurements to use? Are there any scripts that help automate at least some of this process?

• Scriptable BitTorrent clients?

  - by James McMahon

  In an effort further automate all the little computer house keeping tasks that can waste my time I am looking into BitTorrent clients that have the ability to script common tasks. I've done some Googling and it looks like Transmission might have some of said such capabilities, but there site wasn't very clear on the details. Things I am looking to do; Prioritize and label torrents based on trackers Set seed length based on trackers and filesize Set additional seed time when a torrent's seed time expires based on a number of factors, like time spent seeding, remaining disk space and ratio. Move torrents to appropriate places post seeding based on labels and tracker Basically, while I could Python or Bash script things like moving torrents around and other simple actions, I need away to talk to the client to figure out things like the torrent seed time, tracker, labels, filesize, etc. Is there any client out there that would allow me to all or a subset these actions? I have access to Linux, Mac and Windows and am not tied to any particular torrent client. I am a programmer so I have no problems writing scripts, but examples of torrent scripting would also be helpful.

• Excluding files from web logs

  - by Ray

  I originally tried this question on StackOverflow, but it was suggested that serverfault was a better choice. So, here it is... Looking through my web logs, I see a lot of entries that don't interest me. Some of them are commonly used images, css files, and scripts, which I can easily exclude by un-checking the 'log visits' check box in IIS for the folder properties. I would also like to exclude log entries for certain common requests which are not in their own folders. Mostly, 'favicon.ico'. 'scriptresource.axd', and 'webresource.axd'. These (especially scriptresource.axd) make up almost a third of a typical log file on my site. So, the question is, how do I tell IIS not to log these requests? And is there any reason that this is a bad idea? The purpose of doing this is to reduce the log file size and the amount of work the server has to do, to make the log file more manageable when I need to dig in to them for troubleshooting, and for my own curiosity. I realize that log file parsers can skip the junk, but I am interested in reducing the raw files, before parsing.

• systemd: enabling cherokee service as a `unit file`

  - by Calvin Cheng

  So I am learning how to use systemd to initialize my services automatically on server reboot. So of course, I first make sure I have systemd and some optional systemd related packages installed. pacman -S systemd initscripts-systemd Installation seems to go well and checking, I can see that systemd and its dependency libsystemd are installed. And the optional package initscripts-systemd is also installed:- [root@li280-195 ~]# pacman -Ss systemd extra/libsystemd 44-5 [installed] systemd client libraries extra/systemd 44-5 [installed] system and service manager extra/systemd-sysvcompat 2-2 sysvinit compat symlinks for systemd community/initscripts-systemd 20120412-1 [installed] Arch specific systemd initialization/bootup scripts for systemd community/systemd-arch-units 20120412-2 Arch specific Systemd unit files Next, I ensure that systemd is loaded up when my server reboots, via grub in grub's /boot/grub/menu.lst file like this:- kernel /boot/vmlinuz root=/dev/xvda ro init=/bin/systemd Rebooting my server to check, all loads up well and I can check that systemd is operational via:- systemctl list-unit-files However, I don't see my cherokee initialization script (which is simply created at /etc/rc.d/cherokee when I installed cherokee earlier via pacman -S cherokee) being listed as one of my unit files. So the question is, how do I do that? How do I put my cherokee initialization script under systemd's control?

• Monitoring whether Google Apps email address is reachable

  - by Acorn

  Backstory: I bungled things a bit the other day, and inadvertantly deleted the DNS overrides for my domain including the MX records that point to Google Apps, causing 2 days of lost emails. What I want: I want to be able to monitor the email address/account so that I can be alerted if for any reason something has gone wrong and emails aren't arriving. Thoughts: I was thinking there might be a way to test the email without having to send an actual message. Does this exist? This wouldn't help if the DNS has reset itself to a different mailserver would it? The other idea was sending periodic emails to check the address it working. How would you automate this? You'd need to somehow check that the email address had arrived as well as checking if it had bounced. Are there any scripts that exist that would do something like this? What would be the best method? Maybe a combination of checking that the MX records for the domain are set to what they're supposed to be set to, and sending automatic test emails to check that things are still functioning on the Google Apps end?

• Connecting jconsole using SOCKS to Amazon EC2

  - by freshfunk

  I'm trying to use jconsole to view stats on an EC2 instance by using a socks proxy created by SSH. I've tried the various scripts mentioned in the links below but to no avail: http://simplygenius.com/2010/08/jconsole-via-socks-ssh-tunnel.html http://gabrielcain.com/blog/2010/11/02/using-ssh-proxying-to-connect-jconsole-to-remote-cassandra-instances/ I'm running ssh -f -ND 8123 myuser@mymachine and verified that at least Firefox goes through it as a proxy. I then run jconsole -J-DsocksProxyHost=localhost -J-DsocksProxyPort=8123 service:jmx:rmi:///jndi/rmi://ec2-XX-XX-XXX-XXX.compute-1.amazonaws.com:8080/jmxrmi I run netstat -n on my EC2 instance and I see a connection created by my machine. However, the connection eventually disappears and I get a 'channel 2: open failed: connect failed: Operation timed out' from my ssh tunnel. I've opened the jmx port through the security group and I've checked the port on the EC2 instance to make sure it's open (by telnet-ing to it). I'm not sure where to look next. Are there some properties in sshd_config or ssh_config I need to enable for tunneling? Or anything in Mac OS X? I feel like a serious noob but sys administration is really not my strong point. I've spent several hours and can't get this to work.

• Can I get all active directory passwords in clear text using reversible encryption?

  - by christian123

  EDIT: Can anybody actually answer the question? Thanks, I don't need no audit trail, I WILL know all the passwords and users can't change them and I will continue to do so. This is not for hacking! We recently migrated away from a old and rusty Linux/Samba domain to an active directory. We had a custom little interface to manage accounts there. It always stored the passwords of all users and all service accounts in cleartext in a secure location (Of course, many of you will certainly not think of this a being secure, but without real exploits nobody could read that) and disabled password changing on the samba domain controller. In addition, no user can ever select his own passwords, we create them using pwgen. We don't change them every 40 days or so, but only every 2 years to reward employees for really learning them and NOT writing them down. We need the passwords to e.g. go into user accounts and modify settings that are too complicated for group policies or to help users. These might certainly be controversial policies, but I want to continue them on AD. Now I save new accounts and their PWGEN-generated (pwgen creates nice sounding random words with nice amounts of vowels, consonants and numbers) manually into the old text-file that the old scripts used to maintain automatically. How can I get this functionality back in AD? I see that there is "reversible encryption" in AD accounts, probably for challenge response authentication systems that need the cleartext password stored on the server. Is there a script that displays all these passwords? That would be great. (Again: I trust my DC not to be compromised.) Or can I have a plugin into AD users&computers that gets a notification of every new password and stores it into a file? On clients that is possible with GINA-dlls, they can get notified about passwords and get the cleartext.
