Hello, I'm beginning to give up on making Linux-HA's heartbeat work for my environment (CentOS x86_64) and am wondering what other option have I got to help me: 1. Use IPVS to maintain a cluster of virtual servers, either master/slave or load-balanced. 2. Use DRBD in master/slave fashion to keep a home-grown application highly-available. The first thing I stumbled upon is RedHat Cluster

Hello, I'm having a yum problem updating a system on Centos 5.3, 64-bit ... i.e. 'yum update' returns "No Packages Marked for Update". Problem appears to be related to connecting to the mirrors where the repositories are located but I could be wrong in that. What's confusing me is that I have another system (Centos 5.5, 32-bit) that's working fine. Best way to

Hi folks, I've followed a set of instructions I found on http://www.linuxtopia.org/online_books/centos_linux_guides/centos_enterprise_linux_sysadmin_guide/ch-diskless.htmli which describes using system-config-netboot to set up PXE booting.

hi i'm trying to solve this problem, i've came up with a solution, but i don't think that this is the best availibe method for this problem i read about that samba does provides a 'preexec' call that can prevent a share to be accessed, and i figured out, that with this i can reject access to a share if the user have already logged in from another maschine. and if i wrote the

Hi all, I've noticed that OpenSSH 7.7 adds stricter validation of user environment strings from authorized_keys files. While strict validation is a good thing from a security perspective, this new change specifically blocks underscores which are common to include in a user environment string. This results in the key being rejected outright. Including underscores in a user environment is a

Hi all, If I have a dual-boot machine (Linux and Windows) would I have any good tools under Linux that would allow me to look at the content of the Windows boot partition, administer it, clean up the registry, remove viruses if any, etc? The Windows installation seems to be so defective as to be quite useless so I am trying to think of a good strategy for dealing with the situation. Thanks in

Is there any way to configure Mongrel''s logging? Specifically, I''d like to get it to output to syslog. Our Rails apps already do this (via SyslogLogger) - is there any way to persuade Mongrel to do the same? Thanks! -- paul.butcher->msgCount++ Snetterton, Castle Combe, Cadwell Park...

I'm having problems getting a SAMBA share on a remote (Windows XP) machine to allow me write access to files. I can copy/paste whole files OK from my CentOS 5 box, but can't do any editing of files on the Windows XP machine, which I use as a file server for most of my domestic data (historical reasons for using Windows!). I've tried re-setting permissions to allow write access to the

Hi, I''ve been following documentation provided at [1] in order to setup a firewall to use two internet connections with different providers.

I am trying to configure a firewall, but nailing down the configuration is eluding me. The box is running Debian stable. Basically, I have a rackmount server with six network cards. eth0 is the internal network, eth1 is a kiosk network, eth2 is a DMZ/wireless network.
