CentOS 5 :: What Does Rsyslog (using Yum) Install And How To Handle Conflicts With Syslog

Aug 21, 2009

I am thinking about installing rsyslog using yum, but I only want to try it out first and don't want to create conflicts and problems that will be hard to revert. When I ask yum on CentOS 5 about rsyslog, I get this (note much older version - it's too bad that even the latest STABLE rsyslog isn't in the repository):

CentOS 5 :: Syslog-ng Remote Clients But No Local Logs?

May 13, 2010

I installed syslog-ng so I can receive remote logs. this is working however since I disabled syslog on my syslog-ng server I am not logging in /var/log/messages cron and some others.locally)I know this is because my syslog-ng.conf only references remote and not local.How can I edit the syslog-ng.conf file so that I can receive remote and local? I tried this however when adding in portions of the default config, I only receive local and not remote logs anymore. I am forwarding my config.

# syslog-ng configuration file.
# This should behave pretty much like the original syslog on RedHat. But

Ubuntu Servers :: Setting Up Home Server With Backup Imaging For Clients?

Jan 31, 2010

I'm trying to setup a server at home, it has some practical implications, but largely it is just to take a stab at it. But I need the help of someone with more experience than I in defining exactly what I'm looking to do.

Here's what I have: old PC running Gutsy server connected to router. Several laptops at home connected via wifi to router. All laptops running either Windows or Ubuntu. Here's what I'm looking for: The server centralizes file storage for all clients. I would likely incorporate a RAID and some synchronised imaging of the files. I also want the server to create disk images of the clients hdd, regardless of client OS.There would also be some shares that would be publicly accessible (myself and friends accross the country would be able to access the same drive).

So I was thinking something like what corporate environment would be nice, you log into a profile that exists on the server. Like a dumb client...all data would be stored on the server. But I'm thinking that's more like a network boot and wouldn't work via wifi (or would it?). Also that wouldn't lend itself well to laptops used on the road in areas without net access. now I'm thinking each client would have its own locally installed OS, and they would just access networked shares. I could store sensitive files on the shares, but that wouldn't provide complete backup solution for each client.

Without rambling on anymore, anyone care to throw out some ideas? I'm really just looking to see if I can do what I want. The focus is on centrallizing files, securley backing up data and client OS's and ability to restore said images quickly.

Ubuntu Servers :: Run A DHCP Server On Home Network To Enable PXE Booting For Ethernet Clients

I'm attempting to run a DHCP server on my home network to enable PXE booting for ethernet clients, but I'm having quite a few issues getting it all up and running. I'm not entirely sure what is wrong, but I keep encountering errors in syslog as follows:

Feb 27 02:26:46 servnerr-1 dhcpd:

Networking is not exactly my strong suit, but I would like to get this up and running if at all possible.

Ubuntu Servers :: Handle Splitting Services Up Between Two Servers?

May 29, 2010

I got my hands on a couple old servers. An HP tc2021 and a Proliant ML110. Sure they're ancient, but I thought they would make a couple of great Ubuntu Servers for a new "start up" business I'm trying out. Now I've got to decide the best scenario to distribute the load between the two servers. I'm going to make an internal domain and will probably be running the following: Kerberos, Samba, Apache, Postfix, mysql, bind, dhcp, SVN, GCC, and Nagios. So in summary, I'll have the following roles; domain controller, web server, file server, and network monitoring services. how they would handle splitting these services up between two servers?

Jul 23, 2010

i would like to know how many connections per sec/min/hour, xampp can handle. I'm going to run SMF forum on my box, because i'm not ready yet with real server solution. System stats are: G31M-S2C; 2x2GB Kingston@920Mhz; E5200@3500Mhz; 500GB@7200 Seagate, all powered by Lucid x64. In a time i will migrate to a quad, mobo with raid support, etc. but at that point i'm want to know how much connections can xampp handle. Because of the forum nature, i think of auto deleting topics witn no new replys in 5 days for saving place (there will be minimum 1 and maybe max 5 photos per thread, maximum size 2Mb for each).

Ubuntu Servers :: Handle Webroot Permissions When Uploading?

Jul 29, 2011

I have been plagued by this for some time. How many times do you need to run chown -R user:www-data or similar to your webroot directory.I have been searching via Google and this forum. I have yet to find a definite answer to handle uploading and creating new files usable by apache2.Scenarios can vary. Some folks put there webroot inside a /home directory. Some users leave the default location as /var/www.I have a two part question.. Why do I often read "Apache runs as user=www-data, therefore files need to be readable by such (www-data)", but the default install in Ubuntu includes an index.html with the following?

ls -l /var/www
total 4

Fedora Servers :: Syslog Listening On Port 514 For Both Firewall And IDS Logs?

Jan 17, 2010

Currently Im having a syslog server that consolidate firewall logs on port 514 udp. Im also having a IDS device that I wish to push its logs to this particular syslog server so that I can retrieve my IDS logs on this server as well.

Is it possible to do so?Having syslog listening on port 514 for both firewall and IDS logs? If it is possible will the logs be recorded in a single log file?Or will it be recorded in a separate log file ie. firewall.log, IDS.log etc?? I wish to have them in separate individual log files or else there will be hard time segregating the log entries in a single file. Can anyone advice on how to achieve this??

Ubuntu Servers :: Webmin And Syslog-ng Won't Start On Boot After Upgrade From 8.04 To 10.04

Sep 16, 2010

I recently upgraded a Ubuntu server from version 8.04 to 10.04 and after a reboot the webmin and syslog-ng server do not start at boot anymore. I can start them manually by doing /etc/init.d/webmin start and /etc/init.d/syslong-ng start and everything works fine until I root again. Granted this machine is rarely rebooted but when it is, I don't want to have to remember to start these services. I have tried a full removal of syslog-ng and reinstall but to no avail. The entries are in the rc directories like they should and the links are valid.

Ubuntu Servers :: Kernel Errors - Syslog Output At Random Intervals

Jan 28, 2011

I am running a headless Ubuntu 10.04 server with the 2.6.32-28-generic kernel. For what I can figure out no single direct cause I get a high load average and the following syslog output at random intervals. Generally the load average will drop back down to normal however the kernel errors will still continue What little I have been able to find has pointed to memory issues. I am not totaly convinced this is the cause as the server will be showing >50% free when the errors are happening.

Ubuntu Servers :: Syslong-ng -> Mysql For Cacti Syslog Plugin Setup?

Aug 16, 2011

I guess with major changes to syslog-ng, php-syslog going to licensing cost, and major overhaul to the syslog plugin with cacti - alot of documention was either disjointed, outdated or I just couldn't find it.this was performed on an 11.04 Ubuntu Server tall. I already had Cacti up and running and just needed to make it also a syslog collector.This guide assumes you already have mysql running, and cacti is already in place. If something looks wrong - please correct me. I am doing this from memory - trying to remember what all I had to do, and not a super admin.Required ubuntu install packages:libdbd-mysql syslog-ngcacti install packages:[URL]

Stop syslog-ng if you want. Changes should not take effect until you restart it.Should save the default syslog-ng configuration if you want to be safe. Below is the absolute minimum you need to get this working.Configuration on ubuntu is location in /etc/syslog/syslog-ng.conf Also make sure you fill in the proper username and password for mysql.

@version: 3.1
#Bare minimum syslog-ng configuration

Ubuntu Servers :: Kvm Libvirt Lvm VM Consistent Backup - Online And Offline

Apr 12, 2011

What are the solutions to consistently backup a set of VMs stored in disk images (qcow2 or raw) on a filesystem on a lvm volume (with possible snapshots).

- Online : Ideally, I would like to send a sync to all VMs before pause and snapshot, but it seems that it's not possible with KVM (it was with XEN). The save command seemed to be an option, but it crashes some VMs. So, what do you recommend to backup these VMs online ?

- Offline : Is there a command to shutdown all vms, and start them back after snapshot/backup ?
