What is linux server version

How do I find out what version of Linux I’m running?

Is there a way to determine what version (distribution & kernel version, I suppose) of Linux is running (from the command-line), that works on any Linux system?

I’d just like to point out for the record how stupid it is that this is a question which needs asking. This is really quite an indictment on the state of every linux distro.

The kernel is universally detected with uname :

$ uname -or 2.6.18-128.el5 GNU/Linux 

There really isn’t a cross-distribution way to determine what distribution and version you’re on. There have been attempts to make this consistent, but ultimately it varies, unfortunately. LSB tools provide this information, but ironically aren’t installed by default everywhere. Example on an Ubuntu 9.04 system with the lsb-release package installed:

$ lsb_release -irc Distributor ID: Ubuntu Release: 9.04 Codename: jaunty 

Otherwise, the closest widely-available method is checking /etc/something-release files. These exist on most of the common platforms, and on their derivatives (i.e., Red Hat and CentOS).

$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=9.04 DISTRIB_CODENAME=jaunty DISTRIB_DESCRIPTION="Ubuntu 9.04" 

But Debian has /etc/debian_version :

$ cat /etc/debian_version 5.0.2 

Fedora, Red Hat and CentOS have:

Fedora: $ cat /etc/fedora-release Fedora release 10 (Cambridge) Red Hat/older CentOS: $ cat /etc/redhat-release CentOS release 5.3 (Final) newer CentOS: $ cat /etc/centos-release CentOS Linux release 7.1.1503 (Core) 

$ cat /etc/gentoo-release Gentoo Base System release 1.12.11.1 

I don’t have a SUSE system available at the moment, but I believe it is /etc/SuSE-release .

Slackware has /etc/slackware-release and/or /etc/slackware-version .

Mandriva has /etc/mandriva-release .

For most of the popular distributions then,

will most often work. Stripped down and barebones «server» installations might not have the ‘release’ package for the distribution installed.

Additionally, two 3rd party programs you can use to automatically get this information are Ohai and Facter.

Note that many distributions have this kind of information in /etc/issue or /etc/motd , but some security policies and best practices indicate that these files should contain access notification banners.

How can I configure permanent arp entries on Red Hat Enterprise Linux?

I’m configuring a Red Hat Linux server which will be sending UDP packets out but never receiving ARP responses. So a static arp entry is required.

The obvious way to do this is.

arp -s 10.0.0.1 distant_server 

However that won’t survive a network restart or a reboot. I could put it in the rc.local but that doesn’t survive an ifdown && ifup.

The way I’ve found which seems to work is:

Add an entry to /etc/ethers along the lines of:

And create a /sbin/ifup-local:

This feels really hacky, is there a better way?

This is the proper way to both store a permanent arp entry, and to run a command on interface start.

A less hacky way would be to have ARP working properly on the network.

You can do this with nethook, a daemon that runs scripts when network interfaces change state.

Do I compile Ubuntu Source code on Red Hat System?

If we install the Red Hat System then can we compile the other distros of linux on the Red Hat server system? If so, please provide me the tutorials and links.

First If by that you mean creating a custom Ubuntu or other distros yes you can and this action is not entirely distro-specific (i.e in your case Redhat).
For that you could use two diffrerent approaches. Either use automation tools such as linuxcoe and other different tools or go native and start by LFS (Linux From Scratch). Either way you have three things to consider:

For the third option you could use other distros tools also (or write your own)

Or you meant to compile codes for other platforms which is something else and has more to do with your make and build environment and coding skills (writing config files for example). you code do it in Jail env. or Virtual machine if you like.

Or perhaps you meant to access other distros inside a running RedHat.
In this case what you should consider the most is the arch of the Host and target system. This could be done by chroot ing. Consider that you have the live image of some distro in /mnt/distro . first you should mount your /proc , /dev and /sys Then chroot to /mnt/distro .

mount -t proc proc /mnt/distro/proc mount --rbind /sys /mnt/distro/sys mount --rbind /dev /mnt/distro/dev 

Then for chroot ing part you need to specify your environment completely to avoid problems in future.

chroot /mnt/distro /bin/env -i TERM=$TERM /bin/bash 

Note: It is the base idea and the path and env would be different in your case

The simplest and the most proper variant today is to install a target system as a virtual guest, using any kind of virtualization (from a simple chroot through LXC and up to VirtualBox , VMWare , etc.) and then use distro-specific native tools.

You should think of some cross compilation without virtualization under very extreme circumstances.

How to determine what version of .Net Framework is being used by server?

I’ve seen a couple of items on the web about going to regedit and looking at HKLM>Software>NET Framework Setup>NDP and seeing what version folders exist to determine the running version. On the machine I’m working on, I have v2.0.50727, v3.0, v3.5, v4, and v4.0.

I’m trying to run v4.5, and I have installed it via the online download. I do not know if there should be a v4.5 folder at the registry location I mentioned, but it seems like there should be.

The problem I’m having is when I run an sdpx page off the server, I get an error stating unrecognized attribute ‘targetframework’. So, this I assume is telling me that the server is not using the 4.5 framework. If I take out the targetFramework attribute from the config.web files, I get another error saying it cannot locate System.Web.Extensions v4.0.0.0. I have the site’s application pool set to .Net 4.0.

Any help would be greatly appreciated.

Maybe your app not using default pool, if using default app pool, it should work or saying net 4 error.

Just make sure what is app pool name used by your app (site or virtual directory), which net version used by this app pool
