Going to describe this entry a bit later, but in short "ubuntu server edition can't be plain installed on a server via serial console connection, but with custom made iso/cdrom, which is not always an option".

I went to see The Queers last night in concert. It was a decent show, and TA80 was there from Tucson (a great bunch, BTW), as well as The Leftovers (from Maine; also a cool bunch).

Hi Everybody, I am using our only serial port(/dev/ttyS0) for pppd. We are also getting console output through serial. So, to get things going I blocked getty in inittab. I am currently connecting my box via ssh and then i can run pppd, chat script etc.Can I have a setup so that I can give exlusive access of serial to pppd when it runs and when it exits it will unblock it?

Currently we are in the F-11 bootstrap phase. Once that is done, expect to see some technical problems and probable solutions for new packages that we attempt to bootstrap on ARM.

I have installed OpenSolaris on my Core2 Duo E4600 with 1gb of RAM.
What i don't understand, why is it considerably slower in gui, than linux running on the same configuration?

Solaris runs gnome as the default WM, and linux - kde 4.2 from debian-unstable.

How to find Syscall table...

Submitted by jmaladrie
on November 10, 2008 - 2:39am

I needed to recompile my code to test it against UML but it always complained about the unlock_kernel() function. The original code comes from subversity.net

So I decided to slightly modify the code to make it works for UML and x86. I did not have the chance to test it for other architectures.

Fiddling with sys_call_table in Linux Kernel 2.6.21.5

Submitted by Eus
on October 14, 2008 - 3:52am

A friend of mine would like to try to implement a new system call based on the example in Chapter 8 of Linux Kernel Module Programming Guide 2.6 Series (http://www.dirac.org/linux/writing/lkmpg/2.6/lkmpg-2.6.0.html) in Linux kernel 2.6.21.5. The example requires that the kernel exports `sys_call_table' symbol. Although Linux kernel 2.4.x, on which the guide is based, still exposes that symbol, Linux kernel 2.6.x does not do that anymore for it is harmful (e.g., it is unimaginable if a module replace the system call of `link' with `unlink' via the table). The guide comes with a patch to expose the table in Linux kernel 2.6.x. However, the patch does not work in particular for Linux kernel 2.6.21.5. So, I helped him to do so.
