• Running out of LowMem with Ubuntu PAE Kernel and 32GB of RAM

  - by magneticMonster

  I'm running a Java data import process on a 32-bit Ubuntu 10 PAE kernel machine. After running the process for a while, the oom-killer zaps my Java process. After some Googling and digging through docs, it looks like the system is running out of LowMem. I started the process for the third time and am watching free -lm show me Low: 464 386 77 with the free value (77MB) slowly decreasing. Why am I running out of lowmem and how do I increase it? Some details: $ cat /proc/sys/vm/lowmem_reserve_ratio 256 256 32 $ free -lm total used free shared buffers cached Mem: 32086 24611 7475 0 0 24012 Low: 464 407 57 High: 31621 24204 7417 -/+ buffers/cache: 598 31487 Swap: 2047 0 2047

• Puppetmaster don't notice changes to site.pp

  - by tore-

  Hi, I've just setup a new production environment with puppet. Using 0.25.4 in client/server. Ruby is at 1.8.5, CentOS 5.4. I've made a simple manifest for configuring yum-updatesd, but the puppetmaster doesn't seem to notice changes done to site.pp: err: Could not parse for environment production: Could not match 'node' at /etc/puppet/manifests/site.pp:1 err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not parse for environment production: Could not match 'node' at /etc/puppet/manifests/site.pp:1 Notice, it says line 1. But line 1 contains an import statement: # cat -n /etc/puppet/manifests/site.pp 1 import "update-notification" 2 3 node default { 4 include update-notification 5 update-notification::configure() 6 } I've tried to reboot the server, delete and recreate site.pp, start and stop puppetmaster and puppet, with no luck. What am I missing?

• what service to restart for /var/log/auth.log to start

  - by Bond

  Here is a situation since the log files on my server had grown to several Gigabytes I took a backup of directory /var/log and then manually when to each subdirectory of /var/log and the files which were big in size I did cat > /var/log/file_which_is_big press 2 times enter key (basically over wrote those files with a blank space) and then Ctrl+C So basically I over wrote those files to be blank. Now when I open /var/log/auth.log I don't see any entry (which is expected also since I over wrote) but when I exit the SSH session and login again then also I do not see any entry in auth.log is there any way other than rebooting the machine to make sure I keep getting the entries in /var/log/auth.log I am not sure which service writes in this file. This is a Ubuntu 10.04 server.

• Can't resolve localhost on Mac OS X Server

  - by iainbeeston

  I have a server running OS X Server 10.5 and it can't resolve localhost to 127.0.0.1. When I try ping this is what happens: ping localhost ping: cannot resolve localhost: Unknown host SSH and web browsers get similar results (uknown host). If I try using 127.0.0.1 or the ip address assigned on the LAN all of the above work. Here's the contents of my /etc/hosts file: cat /etc/hosts ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost I have no local DNS service running. Does anyone have any idea why this might be happening or how I can fix it?

• Why don't I have write permission to my vmware virtual network device?

  - by Robert Martin

  I want to allow my VMWare machine to force the virtual network it's on into promiscuous mode so I can play around with honeyd. I received an error message that told me to go to http://vmware.com/info?id=161 to allow this behavior. Based on their advice, I did: $ groupadd promiscuous $ cat /etc/group | grep promiscuous promiscuous:x:1002:robert $ usermod -a -G promiscuous robert $ id robert uid=1000(robert) gid=1000(robert) groups=1000(robert),....,1002(promiscuous) $ chgrp newgroup /dev/vmnet8 $ chmod g+rw /dev/vmnet8 $ ls -l /dev/vmnet8 crw-rw---- 1 root promiscuous 119, 8 2012-03-29 10:29 /dev/vmnet8 Looks like I gave RW permission to the promiscuous group, and added myself. Except that VMWare still gives me an error message that says I cannot enter promiscuous mode. To try out the group thing, I tried: $ echo "1" >/dev/vmnet8 bash: /dev/vmnet8: Permission denied That really surprised me: It makes me think that I still haven't properly given myself the correct permissions... What am I missing?

• Windows with putty via USB serial cable to Linux serial port - output ok, input isn't

  - by Aharon Robbins

  I am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5). I have /sbin/agetty -L 9600 ttyS0 in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control. I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but cat < /dev/ttyS0 just prints out weird characters from what I type. Any and all suggestions will be welcome. Thanks!

• setting ulimit and ubuntu 8.04

  - by Wizzard

  Hi there, We have two ubuntu 8.04 servers. With the database server I set the table_cache to 1000 however when I restart mysql the status only shows 257 and the open files limit says 1024 I adjusted ulimit by doing ulimit -n 8192 and then restarting mysql; this seemed to do the tick however after a few hours I did ulimit -n and saw it had returned back to 1024 Bit of a worry. I edited the /etc/security/limits.conf and added mysql soft nofile 8192 mysql hard nofile 8192 then rebooted, no change. I then edited and change mysql to * rebooted, no change I then edited and changed it to one line * - nofile 8192 and rebooted, no change. cat /proc/sys/fs/file-max gives me 768730 sysctl fs.file-max gives me fs.file-max = 768730 I am at a bit of a loss to how I can set and keep the ulimit value set so I can increase the table cache properly on mysql.

• sudo -i not behaving as expected

  - by jpdoyle

  Why sudo -i command is not setting the TERM, PATH, HOME, SHELL, LOGNAME, USER and USERNAME on my fresh Ubuntu 12.04.1 LTS as decribed in the manual? # sudo -u johnny -i echo $HOME && echo $USER /root root Using -H is not setting $HOME either. And my user does exist with a home : # cat /etc/passwd [..] johnny:x:1000:1000::/home/johnny:/bin/bash Update : Why am I having this issue? Because I am trying to create an ubuntu upstart job for multiple unicorn applications & I am using user installation of RVM + Bundle : without $HOME being properly evaluated, RVM do not find ~/.rvm.

• Version `GLIBCXX_3.4.15' not found in CentOS (in file /usr/lib/libstdc++.so.6)

  - by George Kastrinis

  I try to use a program and I get the following error. /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found Under /usr/lib64 the libstdc++ I see is libstdc++.so.6.0.13 (and a soft link).

Should I install some new packages and if yes which ones?

• Stopping an specify Apache instance

  - by user1435991

  I have two Apache instances setup in my server (Solaris 10): Instance 1: /etc/apache2 Instance 2: /etc/apache2-instance2 To start the instance 1, I execute the following command: /usr/apache2/bin/apachectl -f /etc/apache2/httpd.conf And instance 2: /usr/apache2/bin/apachectl -f /etc/apache2-instance2/httpd.conf Both instances run perfectly, however the problem comes when I want to stop the instances. I have not been able to find a parameter to indicate what instance I want to stop. if I execute this command: /usr/apache2/bin/apachectl -k stop It will stop always the Instance 1 (the default one). The only solution that I could find to stop the instance 2 was to do this: kill -TERM 'cat /var/run/apache2-instance2/httpd.pid' Is this the only way to do it? or what is the best solution? I remember that I did something similar in Ubuntu setting a the global variable APACHE_CONFDIR before calling apachectl

• How can I kill and wait for background processes to finish in a shell script when I Ctrl+C it?

  - by slipheed

  I'm trying to set up a shell script so that it runs background processes, and when I ctrl+C the shell script, it kills the children, then exits. The best that I've managed to come up with is this. It appears that kill 0 -INT also kills the script before the wait happens, so the shell script dies before the children complete. Any ideas on how I can make this shell script wait for the children to die after sending INT? #!/bin/bash trap 'killall' INT killall() { echo **** Shutting down... **** kill 0 -INT wait # Why doesn't this wait?? echo DONE } process1 & process2 & process3 & cat # wait forever

• /etc/enviorment not being read into PATH variable

  - by Dan

  In Ubuntu the path variable is stored in /etc/enviorment. This is mine (I've made no changes to it, this is the system default): $ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" but when I examine my PATH variable: $ echo $PATH /home/dan/bin:/home/dan/bin:/bin:/usr/bin:/usr/local/bin:/usr/bin/X11 You'll notice /usr/games is missing (it was there up until a few days ago). My /etc/profile makes no mention of PATH. My ~/.profile is the default and only has: if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi This only happens in gnome, not in tty1-6. This is missing from both gnome terminal and when I try to call applications from the applications dropdown. Anyone know what could be causing this? Thanks.

• How to securely generate memorable passwords?

  - by Tim

  Whenever I need new passwords I use some tools to generate those, preferable memorable passwords, but I've been wondering how secure this might actually be. Using The xkcd random number generator is probably pretty bad, cat /dev/random is probably pretty good, but generating memorable passwords seems a bit more tricky. Whenever a program generates a memorable password, it only uses a subset of the total password space available, and it is not clear to me how big this space is. Of course a long password should help in this case, but if the `memorable' part of the program is too predictable, your passwords are not very good in the end. TL;DR: how secure are memorable password generators, given the fact that `memorable' passwords are a subset of total password space? Some tools I know of: pwgen -- seems ok, but passwords are not too memorable Mac Password Assistant - generates memorable passwords but it is unclear to me how this works.

• sSMTP Unable to send message using external mail server SMTP

  - by OrangeGrover

  I'm trying to finish up my Nagios install by having it email me. It was emailing me using /bin/mail so it always got sent to my spam folders. I installed sSMTP to try to send a request to my work's email server to be able to send out a message from an authenticated user. Here is my /etc/ssmtp/ssmtp.conf file: mailhub=10.200.120.148:25 UseTLS=NO AuthUser= [email protected] AuthPass=PASSWORD So far I've been using the following command, and it will still arrive to my email inbox as root@localhost which causes it to go to my spam folder (with the exception of one email provider I have). cat message |ssmtp [email protected] I've looked at a few examples online, and they all seem to have pretty much the same as me. Does anybody see the any mistakes that I'm making? Just to clarify, [email protected] is a user on the mail server that my work uses.

• Slab uses 88Gb of 128Gb available. What could cause this?

  - by Joris Meys

  We run a debian 2.6.26-2-amd64 x86_64 GNU/Linux on a server with 128 Gb. Recently it our available memory became rather low. Looking at the /proc/meminfo showed that the Slab was using 88Gb, which is counted in the used memory off course. Is this a problem? I suspect that memory will be freed when necessary, but I don't know if that could have unwanted side effects. Why would Slab need that much memory? Is there a clear cause for that? can we avoid this to happen in the future? How can we free this memory? thank you in advance > cat /proc/meminfo MemTotal: 132304500 kB MemFree: 26669388 kB Buffers: 237504 kB Cached: 11881136 kB SwapCached: 48 kB Active: 5244640 kB Inactive: 11714308 kB SwapTotal: 5751228 kB SwapFree: 5750436 kB Dirty: 24 kB Writeback: 0 kB AnonPages: 4840256 kB Mapped: 163968 kB Slab: 88314840 kB SReclaimable: 88275644 kB SUnreclaim: 39196 kB PageTables: 80852 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 71903476 kB Committed_AS: 6818332 kB VmallocTotal: 34359738367 kB VmallocUsed: 505724 kB VmallocChunk: 34359231963 kB

• Dovecot throws obsolete warnings, even though dovecot.conf updated on Ubuntu 11

Dovecot is running: ps -A | grep 'dovecot' 9663 ? 00:00:00 dovecot But I can't seem to get that elusive "dovecot-auth" process. Anyone know what's going on?

• PostgreSQL timezone does not match system timezone

  - by Martin C.

  I have several PostgreSQL 9.2 installations where the timezone used by PostgreSQL is GMT, despite the entire system being "Europe/Vienna". I double-checked that postgresql.conf does not contain timezone setting, so according to the documentation it should fallback to the system's timezone. However, # su -s /bin/bash postgres -c "psql mydb" mydb=# show timezone; TimeZone ---------- GMT (1 row) mydb=# select now(); now ------------------------------- 2013-11-12 08:14:21.697622+00 (1 row) Any hints, where the GMT timezone could come from? The system user does not have TZ set and the /etc/timezone and /etc/timeinfo seem to be configured correctly. # cat /etc/timezone Europe/Vienna # date Tue Nov 12 09:15:42 CET 2013 Any hints are appreciated, thanks in advance!

• Good ways to restart all the computers in a remote cluster?

  - by vgm64

  I have a cluster that I manage and from time to time I get emails from each node (and head node) begging to be restarted after an automatic upgrade. Currently, my best solution so far is a shell script like: $> cat cluster_reboot.sh ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot I end up just typing the root password six times, but it works, I guess. Is there a better way? Can I force the head node to reboot the computers for me?

• LFD always stops working after ~30 days, until I give /etc/csf/csf.pl -r

  - by gus

  When I give /etc/csf/csf.pl -r , I see lots of lines flushing, then I begin to get the notification emails again, (several emails per day), for example: Time: Wed Sep 12 08:39:47 2012 +0800 IP: 221.13.104.162 (CN/China/-) Failures: 5 (sshd) Interval: 300 seconds Blocked: Permanent Block Log entries: Sep 12 08:39:25 MyHost sshd[9677]: Failed password for root from 221.13.104.162 port 51106 ssh2 Sep 12 08:39:28 MyHost sshd[9712]: Failed password for root from 221.13.104.162 port 51690 ssh2 Sep 12 08:39:32 MyHost sshd[9739]: Failed password for root from 221.13.104.162 port 52128 ssh2 Sep 12 08:39:36 MyHost sshd[9778]: Failed password for root from 221.13.104.162 port 52670 ssh2 Sep 12 08:39:40 MyHost sshd[9821]: Failed password for root from 221.13.104.162 port 53155 ssh2 And then after about 30 days, the emails stop coming, it is as if something has filled up, and requires flushing again. I don't know much about CSF/LFD, but I would have imagined that this would work in a FIFO manner, so it should be able to run indefinitely within finite space. My /etc/csf/version.txt says 4.83 My cat /proc/version says Linux version 2.6.18-028stab066.8 (root@rhel5-64-build) (gcc version 4.1.2 20070626 (Red Hat 4.1.2-14)) #1 SMP Fri Nov 27 20:19:25 MSK 2009

• Ubuntu only boots with USB plugged in

  - by Ben

  I'm new to the Linux world so please bear with me! :-) I installed Ubuntu via USB drive onto my hard drive. If I boot the PC without the usb drive I used, Ubuntu will not load. After booting I can unplug without any consequences. I looked on the hard drive and there is a boot folder. On the USB drive, this is the tree contents: /media/disk$ tree . |-- adtext.cfg |-- boot.cat |-- f10.txt |-- f1.txt |-- f2.txt |-- f3.txt |-- f4.txt |-- f5.txt |-- f6.txt |-- f7.txt |-- f8.txt |-- f9.txt |-- initrd.gz |-- isolinux.bin |-- isolinux.cfg |-- ldlinux.sys |-- linux |-- menu.c32 |-- menu.cfg |-- po4a.cfg |-- prompt.cfg |-- splash.png |-- stdmenu.cfg |-- syslinux.cfg |-- text.cfg |-- ubnfilel.txt |-- ubnpathl.txt `-- vesamenu.c32 Am I correct in my assumption that the boot aspect is associated to the USB drive? If so, how do I get it to boot without the USB? I'm guessing copying into some location and modifying grub?
