Hi,
I am not all that certain as to how much of a
problem this is however I do think that it is curious.
If you more or cat the /etc/passwd and pipe it to login,
notice that in /var/adm/messages or /var/log/messages
will produce the following error.
Aug 19 10:54:19 xxxxxxx.xx.xxxxxxx.xxx login: REPEATED LOGIN FAILURES ON /dev/???
NOTE: The xxxxxxx.xx.xxxxxxx.xxx is to hide the host.
--How to repeat:
PROMPT> more /etc/passwd | login
NOTE: you get booted when it it done.
Log back in, or have a second window and type
PROMPT> tail /var/adm/messages OR /var/log/messages
in the messages you will see
Aug 19 10:54:19 xxxxxxx.xx.xxxxxxx.xxx login: REPEATED LOGIN FAILURES ON /dev/???
I do not have time to look into this further however I hope that someone else here does. I am very curious as to why this is happening. Systems that I have tested this on: Sun Microsystems Inc. SunOS 5.6 Generic August 1997
Hope this is nothing serious..
Sincerely,
Adriel T. Desautels
