The Classic Linux environment has always been, and will continue to be, oriented towards “old-timers” who prefer a command-line computing environment. Thus the classic Linux environment tries to provide useful command-line tools including programs for reading Usenet news and electronic mail. It's expected that as a user in this environment you don't mind reading online manuals now and then (with the “man” command), and you write, or would some day like to write, shell scripts or procmail recipes.

If you just want a friendly web-hosting environment where you do most operations from a web control panel, please take a look at our DirectAdmin environment.

Running 32-bit Red Hat 7.2, to be phased out during October or November 2009:

• mauve.rahul.net
• green.rahul.net (unstable)

Recently permanently removed:

• azure.rahul.net, was running 32-bit CentOS 4.x.
• violet.rahul.net, was running 32-bit Red Hat 7.2.

How to connect:

• You can connect to individual machines listed above with ssh as usual.
• Also, from outside our network, you may ssh on any of the ports 22, 80, and 443 to the virtual fault-tolerant host called red.rahul.net. This will lead you one of the above servers. If one server is inaccessible it will connect you to the other one.

Running 64-bit CentOS 5.x:

• oxygen.rahul.net (Recommended.)
• hydrogen.rahul.net
• nitrogen.rahul.net
• helium.rahul.net (Recommended.)
• silicon.rahul.net (Experimental — most changes will be made and tested on this machine first, then propagated to others. Use this machine entirely at your own risk.)

The servers labeled as 'Recommended' are more likely to be reliable. The remaining servers might be in a state of still being configured or being updated.

How to connect:

• You can connect individual machines listed above with ssh as usual.
• Also, from outside our network, you may ssh on any of the ports 22, 80, and 443 to the virtual fault-tolerant host called neon.rahul.net. This will lead you one of the above servers. If one server is inaccessible, it will connect you to another one.

The following machines also run 64-bit CentOS 5.x:

• aqua.rahul.net
• maya.rahul.net

These machines will access your old inbox and will be used solely as a transition aid during our mail system migration 2009.
