'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.
Hope that helps,
