Hi,
I had a strange effect: I tried to debug a program with GNU debugger
when very strange messages appeared on the screen. Like:
(gdb) Undefined command: "3". Try "help".
(gdb) Undefined command: "". Try "help".
(gdb) Undefined command: "". Try "help".
(gdb) Undefined command: "". Try "help".
I found out that a co-worked security-tested the machine with SAINT.
Thus the syslog said this about SSH:
rkdvmhp3 sshd[4041]: Bad protocol version identification 'QUIT
rkdvmhp3 sshd[4095]: Did not receive ident string from 132.199.206.2.
The truely odd thing is that gdb seems to work normally when
I try to capture the output via "script", so it might be a terminal
thing. Anyway I succeeded to capture the output:
/opt/gdb/bin/gdb ~windl/src/C++/HCM/HCMextract

To make things worse, the gdb runs normally if I log in directly as
"v11adm".
In the previous attempt I logged in as "root" and did a "su -
v11adm". Rather
puzzled. Can anybody make any sense in this?
