Howdy, 

I basically have *no* time at the moment, so I just had a very very quick
look at these things. 

Thanks for that quick look! :-)

The biggest file you can find on this machine in this directory is a
gzipped file which probably contains a rootkit of some sort. The SuSE
list is still trying to figure out what the rest does/is and how this
fits into the "big picture".

'i' is a statically linked version of the do_brk() local root exploit. 
Both i.txt and ii.txt appear to be some php injection 'exploits'. 

'n' is a statically linked version of netcat. 

'rhs' appears to be a statically linked version of the 'rs.c' thingy, which
kicks back a shell to a host/port that you specify. 

The perl scripts are amazingly lame backdoors. 

I have too much work to look at the rootkit, sorry.

This is already more than I have hoped for. Thanks VERY much!

I haven't had the chance to look at something like this in the past so
these pointers really are speeding up things. Thanks.

kind regards from Brussels,

Tobias W.
