similar to: Slightly OT: which hardware for CentOS file server (Samba, 2 To storage, 50 users)?

Hi, I'm currently installing a CentOS 5 desktop as a public internet access point. The machine shuts down every day automatically at 22:30. Is there a way I can display a message in GNOME at 22:15 warning the user that the machine will shutdown in 15 minutes ? Any suggestions ? Niki Kovacs

Hi, Up until now, I've only installed Linux either on "desktop" hardware, meaning one of the desktop PCs in the LAN acted as a server machine for the network, or I rented some dedicated server somewhere in a datacenter. Last week I bought some server hardware, a used HP Proliant ML150. It's the first time I am dealing with this sort of hardware. The hardware was sold

Hi, I'm currently writing an install script for an application, and my already limited Bash skills are a bit rusty. I want to check if a group exists, and if it doesn't, then create it. Only thing I found is: if [ grep medintux /etc/group ]; then continue else groupadd medintux fi Apparently I can't seem to "negate" the test, e. g. something like if !(grep medintux

Hi I have read instructions for udev, I also found many example on how to do this. I want to lock in the SDA/SDB/SDC for my drives and I came up with a rule like this KERNEL=="sd?", SUBSYSTEM=="block", ENV{ID_SERIAL}=="ST500DM002-1BC142_W2A56H8A", NAME="sda", RUN+="/usr/bin/logger ID_SERIAL=$ENV{ID_SERIAL} set to /dev/sda ",

Hi, I want to slowly migrate from Debian to CentOS, so I setup a multiboot on my main machine. There's a Debian Etch install on /dev/hda, and GRUB is also installed on the Debian side. On /dev/hdb, I have CentOS 5. I fdisked the drive manually, then chose manual partitioning during install. The setup for CentOS is: hdb1 -> swap hdb2 -> /boot, ext2 hdb3 -> / , ext3 After

I really only ever suggest ntpd unless you?re running an NTP server that provides NTP service to your network, and needs to

Hi, This question is not exactly CentOS-related strictly speaking, but here goes. I'm running a few newsletter servers for myself and a handful of clients on public CentOS servers with PHPList. For the last twenty years or so I've followed the basic rule that mails should have no formatting whatsoever, only simple text. And now I wonder if that basic rule of netiquette also applies to

Hi, I'm currently fiddling with G4U (Ghost for Unix), and I need to setup a local FTP server in order to get it to work. # yum groupinstall "FTP Server" --> installed vsftpd Here's what I'd like to do : * no anonymous access * only one user (user 'install' / pass 'install') The machine I'm installing it on has a static IP ok

Hi, I recently made a CentOS install on a machine with an unsupported network card. I had to add the driver for it later, once I finished the install. For now I have this: [kikinovak at localhost ~]$ hostname --fqdn localhost.localdomain Q: how would I change this to something like calimero.local? Here's what I *would* do, but I prefer to ask before. 1) edit /etc/sysconfig/network and

Hi, I'd like to use SSH without password so I can use it in scripts (for example in combination with rsync to do backups). I have Carla Schroder's "Linux Cookbook" and I'm trying out the various receipts, but the one for SSH without a password doesn't work. The book is slightly dated, and I wonder if SSH included in CentOS works differently. Any suggestions? Niki

Hi, I have a bit of a tricky question about rsync. Let's say I want to backup a bunch of configuration files with rsync, in a script. What I don't want to do : a full snapshot of /etc. What I want to do : backup only those files I need, in an otherwise empty directory tree. In my script, I'd begin with a list of the files I effectively want to backup. Something like :

Hi, I'd like to get my microphone to work (mainly to use it with Skype). I've just been looking for a simple audio recording app, as I vaguely remember having seen such a thing before, only I can't seem to find it anymore. I'm using the default GNOME desktop with the latest CentOS 5. Any suggestions? Niki

Hi, On a minimal (e. g. without X) server install, one of the first things I do is add 'vga=788' to the 'kernel' line in /boot/grub/menu.lst, so I can use the framebuffer in 800x600 mode and have a better readability in console mode. However, I tried this on my minimal CentOS 5 install, and right after GRUB, the screen just blanks. I add that this (test) machine ran maybe a

Hi, The title says it all. One of my clients showed me a 120 GB hard drive that his daughter accidentally formatted, according to him. I booted the first CD I had at hand - a Slackware 11.0 install CD - and launched cdfdisk /dev/hda. cfdisk informed me that there was even no partition table. So much for reformatting. cfdisk only shows me 120 GB of free space. Any way to retrive data on this

Hi, I have to install a small network in a school in a nearby village. The network will be Linux-only, one server and fifteen desktops. Here's the idea. 1) Authentication should be managed centrally on the server. 2) User home directories should also be on the server. 3) Users should all have disk quotas, something like 1 GB per user. 4) Some shared directories should be read/write for

Hi, I'm currently installing and configuring CentOS 7 on a public server. The machine will host a few small-to-midsize projects that are currently running on a handful of Slackware servers: public library databases, our public school's agenda, a small webradio, OwnCloud for myself and a local non-profit, etc. Until recently I've mostly used self-signed SSL certificates for stuff

Hi, One of our local town halls has asked me to implement a wiki-based website dedicated to ecological farming. The wiki is supposed to host a variety of documents in text, video and audio format. I've never used any wiki engines myself. Is there any one you can recommend in particular ? I'm using CentOS 5 on the server, so I would be glad to use a solution where I don't have to
