  • zabbix monitoring mysql database

    - by krisdigitx
    I have a server running multiple instances of mysql and also has the zabbix-agent running. In zabbix_agentd.conf i have specified: UserParameter=multi.mysql[*],mysqladmin --socket=$1 -uzabbixagent extended-status 2>/dev/null | awk '/ $3 /{print $$4}' where $1 is the socket instance. From the zabbix server i can run the test successfully. zabbix_get -s ip_of_server -k multi.mysql[/var/lib/mysql/mysql2.sock] and it returns all the values However the zabbix item/trigger does not generate the graphs, I have created a MACRO for $1 which is the socket location {$MYSQL_SOCKET1} = '/var/lib/mysql/mysql2.sock' and i use this key in items to poll the value multi.mysql[{$MYSQL_SOCKET1},Bytes_sent] LOGS: this is what i get on the logs: 3360:20120214:144716.278 item [multi.mysql['/var/lib/mysql/mysql2.sock',Bytes_received]] error: Special characters '\'"`*?[]{}~$!&;()<>|#@' are not allowed in the parameters 3360:20120214:144716.372 item [multi.mysql['/var/lib/mysql/mysql2.sock',Bytes_sent]] error: Special characters '\'"`*?[]{}~$!&;()<>|#@' are not allowed in the parameters Any ideas where the problem could be? FIXED {$MYSQL_SOCKET1} = /var/lib/mysql/mysql2.sock i removed the single quotes from the line and it worked...

  • Empty /var/log after running cron bash script

    - by Ortix92
    I wrote a little bash script and all of a sudden my /var/log folder is completely empty except for the log I created for the bash script. This is the script I'm running every hour with cron: #!/bin/bash STL_DIR=/path/to/some/folder/i/hid LOGFILE=/var/log/stl_upload.log now=`date` echo "----------Start of Transmission----------" 2>&1 | tee -a $LOGFILE echo "Starting transfer at $now" 2>&1 | tee -a $LOGFILE rsync -av -e ssh $STL_DIR [email protected]:/users/path/folder 2>&1 | tee -a $LOGFILE echo "----------End of transmission----------" 2>&1 | tee -a $LOGFILE printf "\n" 2>&1 | tee -a $LOGFILE I want to be clear that I'm not 100% certain this is related to the empty logs folder. So if anyone could give me a pointer as to what could be going on about the reason why my log folder is empty, that'd be great.

  • ProFTPd server on Ubuntu getting access denied message when successfully authenticated?

    - by exxoid
    I have a Ubuntu box with a ProFTPD 1.3.4a Server, when I try to log in via my FTP Client I cannot do anything as it does not allow me to list directories; I have tried logging in as root and as a regular user and tried accessing different paths within the FTP Server. The error I get in my FTP Client is: Status: Retrieving directory listing... Command: CDUP Response: 250 CDUP command successful Command: PWD Response: 257 "/var" is the current directory Command: PASV Response: 227 Entering Passive Mode (172,16,4,22,237,205).

  • What can go wrong with a GLIBC upgrade?

    - by Sevenless
    I recently installed a piece of software that my group needs for a research project starting next September. Turns out the software has a known crash bug when used with glibc 2.12.1. My boss asked if we can upgrade glibc on the server that's supposed to run it. Cue my skeptical silence.... At some point, I got it into my brain that messing with glibc was about as good an idea as messing with a hungry puma; however, I've been unable to determine the source of this belief. So, if I go ahead with this: Am I doing something flagrantly stupid (e.g. I won't fix my problem, I will brick my server, or I will initiate a zombie apocalypse)? What can go wrong? What is likely to go wrong? How do I avoid the answers to 2 and 3?

  • activate wireless chip on ubuntu

    - by Charles
    I am currently using ubuntu 10.10 on my laptop , the model of my wireless chip is broadcom BCM4312 802.11b/g LP-PHY . I tried to activate the driver for the chip by clicking menu bar System - Administration - Additional Drivers . and activated Broadcom STA wireless driver. But the laptop can't detect any wireless signal still. Do I have to do any additional work to make the chip work ? Or how can I test if there is physical damage to the chip itself

  • How do I securely execute commands as root via a web control panel?

    - by Chris J
    I would like to build a very simple PHP based web based control panel to add and remove users to/from and add and remove sections to/from nginx config files on my linode vps (Ubuntu 8.04 LTS). What is the most secure way of executing commands as root based on input from a web based control panel? I am loathe to run PHP as root (even if behind an IP tables firewall) for the obvious reasons. Suggestions welcome. It must be possible as several commercial (and bloated, for my needs) control panels offer similar functionality. Thanks

  • Alsa hardware volume with PulseAudio

    - by Jan Hudec
    Before installing pulseaudio, I was able to control volume for the front (meaning on the front panel, the "headphone" jack) and rear (meaning on the back panel, the "line out" jack) separately. When I installed pulseaudio, it became possible to control volume for each playing process separately, but the individual controls for outputs disappeared. While the default device in alsa now routes via pulseaudio, the sysdefault device provides access to the hardware. But kmix does not seem to let me show them now. Is there any way to beat kmix into showing the sysdefault device too? Or something else X-based that would not fight with kmix too much? The system is Debian Jessie (testing) amd64, updated, KDE version 4:4.13.3-1.

It exits without error, but no "Hello" appears int the output of: dmesg I am using a Fedora 9, and it seems that there is no syslogd/klogd daemon running. However, all my kernel messages are succesfully written in the dmesg buffer. Any idea?

  • KVM Guest not reachable from host

    - by Paul
    Hello, I'm running Ubuntu server 9.10, installed KVM etc. Created the bridge network following instructions on help.ubuntu.com/community/KVM/Networking Created a windows 2008 guest using virt-install command line (using virt-manager GUI from a remote Ubuntu desktop would not let me select the ISO location). I can however use a remote virt-manager to connect to the guest and complete the windows install. Within windows 2008 I changed the IP address but cannot ping from outside world. The bridge network appears fine - I'm not sure what else to look at! Here is the interfaces file: The loopback network interface auto lo iface lo inet loopback The primary network interface auto eth0 iface eth0 inet manual # auto br0 iface br0 inet static address 60.234.64.50 netmask 255.255.255.248 network 60.234.0.0 broadcast 60.234.0.255 gateway 60.234.64.49 bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 auto eth1 iface eth1 inet static address 192.168.12.2 netmask 255.255.255.0 broadcast 192.168.12.255 The ip of the windows server is 60.234.64.52 What else should I check? Regards Paul.

  • hosts.deny not blocking ip addresses

    - by Jamie
    I have the following in my /etc/hosts.deny file # # hosts.deny This file describes the names of the hosts which are # *not* allowed to use the local INET services, as decided # by the '/usr/sbin/tcpd' server. # # The portmap line is redundant, but it is left to remind you that # the new secure portmap uses hosts.deny and hosts.allow. In particular # you should know that NFS uses portmap! ALL:ALL and this in /etc/hosts.allow # # hosts.allow This file describes the names of the hosts which are # allowed to use the local INET services, as decided # by the '/usr/sbin/tcpd' server. # ALL:xx.xx.xx.xx , xx.xx.xxx.xx , xx.xx.xxx.xxx , xx.x.xxx.xxx , xx.xxx.xxx.xxx but i am still getting lots of these emails: Time: Thu Feb 10 13:39:55 2011 +0000 IP: 202.119.208.220 (CN/China/-) Failures: 5 (sshd) Interval: 300 seconds Blocked: Permanent Block Log entries: Feb 10 13:39:52 ds-103 sshd[12566]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=202.119.208.220 user=root Feb 10 13:39:52 ds-103 sshd[12567]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=202.119.208.220 user=root Feb 10 13:39:52 ds-103 sshd[12568]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=202.119.208.220 user=root Feb 10 13:39:52 ds-103 sshd[12571]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=202.119.208.220 user=root Feb 10 13:39:53 ds-103 sshd[12575]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=202.119.208.220 user=root whats worse is csf is trying to auto block these ip's when the attempt to get in but although it does put ip's in the csf.deny file they do not get blocked either So i am trying to block all ip's with /etc/hosts.deny and allow only the ip's i use with /etc/hosts.allow but so far it doesn't seem to work. right now i'm having to manually block each one with iptables, I would rather it automatically block the hackers in case I was away from a pc or asleep

  • php processes owned by ppid 1 after X amount of time

    - by Kristopher Ives
    I have a CentOS server running WHM that uses FastCGI (mod_fcgid) running PHP 5.2.17 on Apache 2.0 with SuExec. When I start Apache it begins fine and serving requests. If I run ps on the terminal as root I see the php processes and they are owned by their httpd parent processes. After X amount of time - different from time to time, not much longer than a few hours typically - the server will begin spawning PHP jobs owned by the init process ID (1) Example of good listing: 12918 18254 /usr/bin/php 12918 18257 /usr/bin/php 12918 18293 /usr/bin/php 12918 18545 /usr/bin/php 12918 18546 /usr/bin/php 12918 19016 /usr/bin/php 12918 19948 /usr/bin/php Then later something like: 1 6800 /usr/bin/php 1 6801 /usr/bin/php 1 7036 /usr/bin/php 1 8788 /usr/bin/php 1 10488 /usr/bin/php 1 10571 /usr/bin/php 1 10572 /usr/bin/php The php processes running owned by (1) never get cleaned up. Why would these processes be running? We don't use setsid or anything beyond basic PHP in the code this server is running. Cheers & Thanks

  • Website memory problem

    - by Toktik
    I have CentOS 5 installed on my server. I'm in VPS server. I have site where I have constant online ~150. First look on site looks OK. But when I go through links, sometimes I receive Out of memory PHP error. It looks like this Fatal error: Out of memory (allocated 36962304) (tried to allocate 7680 bytes) in /home/host/public_html/sites/all/modules/cck/modules/fieldgroup/fieldgroup.install on line 100 And always, not allocated memory is very small. In average I have 30% CPU load, 25% RAM load. So I think here is not a physical memory problem. My PHP memory limit was set to 1500MB. My apache error log looks like this [Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Out of memory, referer: http://www.host.com/17402 [Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Premature end of script headers: index.php, referer: http://www.host.com/17402 [Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Out of memory, referer: http://www.host.com/17402 [Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Premature end of script headers: index.php, referer: http://www.host.com/17402 [Thu Sep 30 17:49:00 2010] [error] [client 91.204.190.5] File does not exist: /home/host/public_html/favicon.ico Past I have not met with this on my server and the problem appeared itself. Besides this I'm receiving some server errors on mail. cpsrvd failed @ Fri Sep 24 16:45:20 2010. A restart was attempted automagically. Service Check Method: [tcp connect] Failure Reason: Unable to connect to port 2086 Same for tailwatchd. Support tried, and can't help me...

  • Setting background color in gvim

    - by petersohn
    I use a terminal with white text on black background (I just like it better), so I wrote the following line in my .vimrc file: set background=dark However, gvim has black on white text. How do I do either of the following: Set the background of gvim to black Check in .vimrc if I'm using gvim I tried this: I started up gvim, and typed echo &term. The answer was "builtin_gui". So I wrote the following into .vimrc: if &term == "builtin_gui" set background=light else set background=dark endif Somehow, it didn't work.

  • idle proccesses and high memory bad? uwsgi/django

    - by JimJimThe3rd
    I have a VPS with 256MB of ram. I'm running nginx, uwsgi and postgresql on Ubuntu 12.04 for a soon to be Django site. About 200MB of ram are being used despite the website not being active, the uwsgi processes seem to just be idling. Is this bad? I once heard that having a bunch of free memory isn't necessarily a good metric because it is possible that the memory in use can easily be freed up. I mean, it is possible that the server is storing commonly used "stuff" in case it is accessed but is more than happy to dump it if the ram is needed. But I'm really not sure, hence me asking this question. If it is bad I could set some of the application loading options for uwsgi like "cheap" or "idle" mode. Screenshot of my htop

  • How to make new file permission inherit from the parent directory?

    - by Wai Yip Tung
    I have a directory called data. Then I am running a script under the user id 'robot'. robot writes to the data directory and update files inside. The idea is data is open for both me and robot to update. So I setup the permission and owner group like this drwxrwxr-x 2 me robot-grp 4096 Jun 11 20:50 data where both me and robot belongs to the 'robot-grp'. I change the permission and the owner group recursively like the parent directory. I regularly upload new files into the data directory using rsync. Unfortunately, new files uploaded does not inherit the parent directory's permission as I hope. Instead it looks like this -rw-r--r-- 1 me users 6 Jun 11 20:50 new-file.txt When robot tries to update new-file.txt, it fails due to lack of file permission. I'm not sure if setting umask helps. In anycase the new files does not really follow it. $ umask -S u=rwx,g=rx,o=rx I'm often confounded by Unix file permission. Do I even have a right plan? I'm using Debian lenny.

  • Simple NNTP clent for Ubuntu

    - by Alexander Gladysh
    I need to download a particular NNTP group. I do not need to setup any crons, put group contents in /opt and other stuff. Just run <fetch-nntp> <server> <group-name> <output-dir> and be done with it without putting a lot of garbage in the system. If that <fetch-nntp> would not fetch the same messages on the second run — fine. But I can live without it. All NNTP clients that I've looked at are trying to be a NNTP server as well. Is there something simpler that is suitable for my needs?

  • Xinetd , vncserver memory requirement

    - by JP19
    Hi, I am installing the following on a low memory system: vnc4server xinetd xterm openbox obconf I will only occasionally be logging into the vncs for some admin work. My question is: 1) Does xinetd take memory / cpu even when vncserver is not running? If so, can I "run" xinetd on demand (how)? And if no, any idea how much memory it will take when vncserver is not running? 2) Does vncserver take substantial memory when no clients are connected? 3) Do openbox/obconf take memory when vncserver is running but no client are connected? 4) Do openbox/obconf take memory when no vncserver is running? thanks JP

  • Updating Network Solutions Virtual Private Server

    - by Peter Turner
    Just got a VPS from Network Solutions, it's got Red Hat 4, PHP 5.16, Java 1.4, no Yum and a whole bunch of packages I'd expect to have from a fresh install. Anyway, obviously I sound like a spoiled Ubunutoligist, but do I seriously have to manually update all this stuff, is there a shortcut, I'm used to Fedora, so I'm not sure what the differences are between using Yum in Redhat and Fedora. Should I just demand that Network Solutions give me a server that's not 4 years old or is there a way to update this thing that won't take all week?

  • Reboot VPS by reaching memory limit

    - by Ali
    When a server uses memory more than available RAM, the system will shut down the virtual machine. Then, it is only possible to boot from outside (VPS control panel, e.g. vePortal or SolusVM). However, it should be possible to plan a reboot before possible shut down. What is the best practical method to check the used memory, and reboot the system upon reaching e.g. 90% of the allowed RAM? Is there a common program or script to do so? I am using Debian/Ubuntu.
