Hello Ronelle,
All,
I am relatively new to AIX - having come back to it after a 12 year
hiatus - and I am experiencing some strange ssh and NIS issues that I
can't find answers to on the net.
The server is running AIX5.3 and it is a P6.
SSH (but sounds like NIS really)
For some reason I can't ssh to the server as myself (a nis user) - I
get a "permission denied" from a unix server and an unexpected close
on putty from my desktop.
The following is in /var/log/secure:
Jul 11 17:11:35 uxcpti02 auth|security:info sshd[618816]: reverse
mapping checking getaddrinfo for ranger.cpt.intecbilling.com
[158.155.41.43] failed - POSSIBLE BREAK-IN ATTEMPT!
Jul 11 17:11:42 uxcpti02 auth|security:info sshd[618816]: Accepted
password for vanniekr from 158.155.41.43 port 52394 ssh2
Jul 11 17:11:42 uxcpti02 auth|security:crit sshd[614696]: fatal:
permanently_set_uid: was able to restore old [e]gid
And this is the only difference of a debug output to one that works:
debug3: channel 0: status: The following connections are open:
#0 client-session (t3 r-1 i0/0 o0/0 fd 4/5 cfd -1)
debug3: channel 0: close_fds r 4 w 5 e 6 c -1
Connection to uxcpti02 closed by remote host.
Connection to uxcpti02 closed.
debug1: Transferred: stdin 0, stdout 0, stderr 79 bytes in 0.2 seconds
debug1: Bytes per second: stdin 0.0, stdout 0.0, stderr 505.4
debug1: Exit status -1
I can su from root into any users, and some nis users can log in - the
ones who do not have to have their home directories automounted
(although automount obviously works when su'ing.)
The following is the entry in my /etc/passwd file:
+::0:0:::
My server is also totally inaccessible when I reboot the nis server -
I have to hard boot it
What am I missing?
-Ronelle van Niekerk
what does your server lookup for ranger.cpt.intecbilling.com?
Simply do:
host ranger.cpt.intecbilling.com
and
host 158.155.41.43
Do you have wrong entries in your /etc/hosts file?
Are you using the right DNS?
Cheers,
ku

I beg your pardon General Solo, but that just

Proper???
