• clam anti-virus is slowing down my server performance

  - by Scarface

  Hey guys, I just installed clam av http://sourceforge.net/projects/php-clamav/ for scanning file uploads on my linux VPN running php. The problem is that for some reason just initiating the extension in the php ini file slows down my entire network. Regular requests such as changing pages that should take less than 1 second take 5. Has anyone ever experienced this before or have a good virus scanning alternative for scanning file uploads? extension=clamav.so [clamav] clamav.dbpath="/usr/share/clamav" clamav.keeptmp=20 clamav.maxreclevel=16 clamav.maxfiles=10000 clamav.maxfilesize=26214400 clamav.maxscansize=104857600 clamav.keeptmp=0

• What do you use to loadbalance IPv6 services?

  - by Michael Renner

  Hi, the current Linux software environment for IPv6 load balancing looks a bit grim. IPVS has rudimentary support for IPv6 but it's far from complete. NAT for IPv6 seems to be a no-go. Are there any other projects which aim for this goal? Does the IPv6 support in other OS look better? Are there any commercial products which have been successfully used in production environments with non-trivial load patterns? Or is it just that the time for IPv6 hasn't come... yet? ;) best regards, Michael

• How can I create persistent SSH connection to "stream" commands over a period of time?

  - by Darth

  Say that I have an application running on one PC that is sending commands via SSH to another PC on the network (both machines running Linux). For example every time something happens on #1, I want to run a task on #2. In this setup, I have to create SSH connection on every single command. Is there any simple way to do this with basic unix tools without programming custom client/server application? Basically all I want is to establish a connection over SSH and then send one command after another.

• Using the right folder for the right job. Article link, please?

  - by Droogans

  There are specific folders designed for specific tasks. /var/www holds your web sites, /usr/bin contains files to run your applications...yet I still find myself putting nearly all of my work in ~. Is it possible to overuse my home directory? Will it come back to haunt me? Anyone have a good link to an article of best practices for organizing your files so that they are placed in their "correct" place? Is there even such a thing in Linux? I am referring specifically to user-generated content. I do not compile applications from source, I use apt-get for those tasks. This article has a great introduction to what I'm looking for. Table 3-2, "Subdirectories of the root directory" is the sort of thing I'm looking for, but with more details/examples.

• How to increase max FD limit for a daemon process running under a headless user?

  - by Ameliorator

  To increase the FD limit for a daemon process running under a headless user on a Ubuntu Linux machine we did following changes in /etc/security/limits.conf soft nofile 10000 hard nofile 10000 We also added session required pam_limits.so in /etc/pam.d/login. The changes got reflected for all the users who logged out and logged in again. Whatever new processes are starting under those users are getting new FD limits. But for the daemon which is running under a headless user the changes are not getting reflected. what is the way by which the changes can be reflected for the daemon which is running under headless user ?

• Re-assembling the RAID-5 array reboots my CentOS-5 machine

  - by xraminx

  I have 3 HDD's, each divided into 3 partitions. I had created a RAID-1 for boot partition md0 created from sda0, sdb0 and had also created two RAID-5 arrays: md1 created from sda1, sdb1, sdc1 md2 created from sda2, sdb2, sdc2 It used to work fine but one day I had to power off the machine (cold reboot) to get any response from the machine. After that, when the system started booting, it tried for a while to reconstruct the RAID arrays but after a few minutes it crashed silently. I booted the system in linux rescue mode from the DVD and tried to re-assemble the RAID devices manually. I was able to re-assemble md0 and md1 using: mdadm --assemble --scan /dev/md0 mdadm --assemble --scan /dev/md1 But when I try to re-assemble md2 using: mdadm --assemble --scan /dev/md2 the system reboots silently again. How can I fix this problem?

• What is the difference between /sbin/nologin and /bin/false?

  - by Michael Hampton

  I have often heard it recommended that a user account should be disabled by setting its shell to /bin/false. But, on my existing Linux systems, I see that a great number of existing accounts (all of them service accounts) have a shell of /sbin/nologin instead. I see from the man page that /sbin/nologin prints a message to the user saying the account is disabled, and then exits. Presumably /bin/false would not print anything. I also see that /sbin/nologin is listed in /etc/shells, while /bin/false is not. The man page says that FTP will disable access for users with a shell not listed in /etc/shells and implies that other programs may do the same. Does that mean that somebody could FTP in with an account that has /sbin/nologin as its shell? What is the difference here? Which one of these should I use to disable a user account, and in what circumstances? What other effects does a listing in /etc/shells have?

• Compiling to a binary from source

  - by Chords

  I'm using WKHTMLTOPDF on a 64-bit Linux server and I'm running into problems with the version. Seen here: http://code.google.com/p/wkhtmltopdf/downloads/list There's slim pickins when it comes to pre-compiled binaries. I started with version 0.9.9 which has a few bugs. I upgraded to 0.11.0 RC 1 to find a slew of new problems, namely the following: http://code.google.com/p/wkhtmltopdf/issues/detail?id=730 I think 0.10 RC 2 would work, and the thread above suggests compiling from the source has a fix for the error I'm getting, but I don't know how to do that. Can anyone explain how I can create a static binary myself, or would anyone be willing to create and post one for the countless people waiting for this fix?

• Webserver security, intrusion detection, and file intregrity

  - by enfield

  I would like to add some type of tracking / alerting on some linux webservers running PHP and Apache. In doing searches I have come across a lot of info from 2006-2009. Would like to revisit things and see what others are doing now. The main purpose here is to track when any files are changed and if so alert me somehow. The same goes for IDS and hopefully something that can reside on same server? Since some of these are small scale projects I would prefer opensource/free solutions that are really effective. Although I would still like to hear of other alternatives if someone has the experience and the cost can be justified.

• setting nproc in /etc/security/limit.conf prevents ssh login

  - by omry

  I am trying to use /etc/security/limit.conf on Linux (Debian) to limit the number of processes per user. for starters, I tried to limit my own user processes by adding this to /etc/security/limit.conf: omry hard nproc 100 this locked my user out of ssh. I could open new processes (verified with su omry), but could not log into ssh with that user : sshd reported this in it's log: fatal: setreuid 1000: Resource temporarily unavailable also, I am certain my user is not running anything near 100 processes (actually 6). what can be the reason for this?

• Segfault with rtorrent on Debian Lenny

  Hi, My debian lenny server keeps segfaulting with rtorrent, it happens once every 24 hours. Libcurl has been recompiled to the latest version and it still seems to happen. I'm not the best when it comes to linux server admin but if you require more info about the system I'll try and get it for you. lib/rtorrent are 0.8.5/0.12.5 Any help would be appreciated as I'd like rtorrent up 24/7 Caught Segmentation fault, dumping stack: 0 rtorrent [0x439686] 1 rtorrent [0x43e06a] 2 /lib/libc.so.6 [0x7f73ce780f60] 3 /usr/lib/libcurl.so.4 [0x7f73d04f4431] 4 /usr/lib/libcurl.so.4 [0x7f73d04f47da] 5 /usr/lib/libcurl.so.4(curl_multi_remove_handle+0x341) [0x7f73d050acb1] 6 rtorrent [0x480221] 7 rtorrent [0x482915] 8 /usr/local/lib/libtorrent.so.11 [0x7f73d02b1f95] 9 /usr/local/lib/libtorrent.so.11 [0x7f73d02b1fea] 10 /usr/local/lib/libtorrent.so.11 [0x7f73d02b4cfc] 11 rtorrent [0x48058a] 12 rtorrent [0x439f49] 13 /lib/libc.so.6(__libc_start_main+0xe6) [0x7f73ce76d1a6] 14 rtorrent(_ZNSt8ios_base4InitD1Ev+0x71) [0x40ea99]

• What is the EGG environment variable?

  - by Randall

  A user on our (openSuSE) linux systems attempted to run sudo, and triggered an alert. He has the environment variable EGG set - EGG=UH211åH1ÒH»ÿ/bin/shHÁSH211çH1ÀPWH211æ°;^O^Ej^A_j<X^O^EÉÃÿ This looks unusual to say the least. Is EGG a legitimate environment variable? (I've found some references to PYTHON_EGG_CACHE - could be related? But that environment variable isn't set for this user). If it's legit, then I imagine this group has the best chance of recognizing it. Or, given the embedded /bin/sh in the string above, does anyone recognize this as an exploit fingerprint? It wouldn't be the first time we had a cracked account (sigh).

• Kickstart virtual console: No 'Shell prompt' at Alt-F2

  - by Stefan Lasiewski

  I am installing Scientific Linux 6.1 via kickstart, and I am trying to debug a problem. According to Tips and tricks for anaconda and kickstart, I should have several virtual consoles available: What the different terminals display Alt-F1 The installation dialog when using text or cmdline Alt-F2 A shell prompt Alt-F3 The install log displaying messages from install program Alt-F4 The system log displaying messages from kernel, etc. Alt-F5 All other messages Alt-F7 The installation dialog when using the graphical installer The Virtual Consoles Alt-F1, F3, F4 & F5 all work and show various logging information. However, the Virtual Console at Alt-F2 does not do anything. I could really use access to the shell prompt (Alt-F2), however there is no Shell prompt available at the second virtual console (Alt-F2). All I have is a blinking '_'. Can I forge Alt-F2 to show me a shell prompt?

• Dummy HTTP server for debugging

  - by Andrea

  This is more or less the inverse of my previous question. I need to debug some HTTP requests that I am making. Since these requests arise from the use of some external libraries, sometimes I am not sure of what is the actual data I am sending. Is there some dummy server (for Linux) that accepts HTTP requests and just prints them somewhere so that I can inspect them? I would like to be able to see in plain text the full request, like POST /foo HTTP/1.1 Host: www.example.com Accept: text/xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Language: en-gb,en;q=0.5 Content-Type: text/plain Content-Length: 11 Hello world

• Measuring cumulative network statistics per user or per process

  - by zsimpson

  I've been googling for hours -- Under Linux I want to know the cumulative bytes sent and received by user or by process over all ip protocols. The best I've found in my searches is that it's possible to use iptables to mark packets for a user, for example: iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner test -j MARK --set-mark 1 It appears that "tc" can then shape traffic with that but I just want the statistic -- I don't want to shape the traffic. I want something like: "user U has transmitted used XMB since time Y". I can't figure out how to get statistics from these marked packets. Also, I've looked at nethogs but they seem to be measuring the instantaneous flow and I need cumulative counts. Anyone have ideas?

• Automatically encrypting incoming email

  - by user16067

  I have a small website and would like to encrypt incoming email using gpg. Is there a way to force sendmail to check email and encrypt it if its not already encrypted? I'm using GPG on a linux server. Thanks [added]Someone asked what I hope to accomplish. My intent is for the users of the email to become more familiar with seeing thier own email encrypted and losing that fear of the unknown. The side benefit is that the email can't be looked at later down the road. If the email isn't encrypted on its way in, I'm unable to do anything about it. I'm assuming most email would be nosed around with once its already on my hard drive, so GPG would protect against those issues.

• Make own dial-up ISP using broadband connection [on hold]

  - by SkylarMT

  So, I see no reason why this wouldn't be possible. I have a Linux server (a Raspberry Pi to be exact) connected via Ethernet to a broadband ISP. I want to be able to dial a number, have it go through the normal telephone network, onto the Internet via a VoIP provider (I know you can call a Skype user from a landline), to my Raspberry Pi, and then have the Pi connect me to the Internet. I've found guides on making your own ISP, but they all involve a dedicated phone line on the server end. Is there a way to do this with no modem on the server end? I live in an area with a lot of people still on dialup, and if I pull this off I could make some extra money. Thanks!

• Sending UDP/514 data magically appears in syslog without rsyslog running

  - by ale

  I’m using a programming language without a library to log to rsyslog over UDP. I thought I was going to need to write a library but I discovered something weird. If I send data on UDP/514 with the port open on the server then the data appears in the server’s syslog. rsyslogd isn’t running so syslog isn’t doing this. Data doesn’t get formatted into a syslog message so rsyslogd really isn’t doing this (only raw text enters syslog). Linux must see the data coming in on this port and know that it should go into /var/log/messages? If I do the same on another port (e.g. UDP/515) then nothing appears in the log! What is doing this? Some CentOS feature? The kernel?

• Making TT-RSS cache images

  - by Piku

  Due to Google Reader's untimely demise, I've installed tiny-tiny RSS on my Linux machine under Apache 2. It's mostly a good enough replacement and I can at least go back to reading RSS feeds in my web browser at work. Can I configure or hack TT-RSS to cache all the images it finds in its feeds? There is an option when adding a feed, but it doesn't seem to actually do anything. If I view (for example) today's XKCD comic in TT-RSS it still loads the image from the XKCD website. What I want is the image to be cached in TT-RSS and served from there instead.

• Using rsync to take backup of folder

  - by Ali

  Hi, I have a server (Linux) with NAS which is mounted as folder "mount" I have website in "public_html" folder. I want to take backup of website in mount folder automatically at certain intervals for e.g. every hour. I read that there is something called "rsync" which is used to make two folders sync. And it doesn't copy all files every time and instead matches if the file has been changed and then only update changed files. How do I use it to make automatic backups? I have root access to server. Thanks

• List of MD /Raid/LVM (Devices) = How to mount them without any further information available?

  - by Jens

  Hello Expets, I do not have much skills in linux and installed a system two years ago that I now had to reboot, but it seems I did not automate everything with start-scripts... My Problem: I miss some mountpoints. I have a list of my raids (excerpt:) md3 : active (auto-read-only) raid1 sda6[0] sdb6[1] 97659008 blocks [2/2] [UU] md4 : active (auto-read-only) raid1 sda7[0] sdb7[1] 250099776 blocks [2/2] [UU] and it seems md3 and md4 are NOT mounted. However i do NOT have any entries for them fstab file. What should I do next. I do NOT know which filesystem they have (most likely ext3). =Can I savely try to mount them with (mount -t ext3 /dev/md3 /mnt/mymntpoint) or will the lead to corrupted data, in case they are not ext3? What should I do next (based on the information given above). The goal is to remount these Devices again, but I do not know anything about them anymore... Thank you very much Jens
