I seem to be able to connect to it:

srdjan@nietzsche:/plato-home/srdjan$ uml_mconsole wWko45
(wWko45) config eth0
ERR No get_config routine defined
(wWko45) cad
OK 

although cad didn't do anything.


It worked yesterday with 2.4.22-5um-1, I only could not make network go, which I hoped to resolve today (but then I upgraded...:)
I've installed kernel-patch-skas, but it refused to patch my 2.4.22 kernel. Any suggestions?

Thanks,
srdjan

| Apparently, tt mode is broken.  I use skas, which is working fine in
| 2.4.22-7um-1, but I can reproduce your failure with mode=tt.
