Greetings forumers,
Sorry about the off topic issue (although it involves a Solaris box),
but I am stuck with this and this is a really great forum.
I will summarize.
- Secure Shell A.03.81.002 ;
- Can login by ssh from any hosts, no problem here;
- Cannot login to anyhost, even to localhost;
- known_hosts is not being populated; No idea why;
First Scenario:
- Get the "Host key verification failed" message whenever I try to
login;
A piece of the log is below. The coplete log, as well as sshd_config and
ssh_config is attached.
Any help would be much appreciated. Thanks in advance, folks!
Filipe.
