Make two modification:-
(1) comment everything in /etc/resolve.conf
Interesting. That change alone fixed it. So I tried copying resolv.conf from one of my OL 5.6 machines, but that did *NOT* fix it. And of course, that alone is not a viable solution because resolve.conf gets regenerated at every boot up.

I take it there is a typo there, as there is no file by that exact name:
So I went with the second, and made made this change:
HTML Code:
[root@vblnxsrv02 etc]# grep UseDNS ./ssh/sshd_config
UseDNS no
That worked *after* a reboot - which of course reset the resolv.conf. So either of the two is sufficient independent of the other, and of course the second (sshd_config) is the only one that is persistent.
Which then led me back to compare with my OL 5.6 installation. It had the same setting as we started with on the 6.3 :
So at this point I have a workable solution, but no explanation of why it is *different* on the 6.3 machine - why it *needs* to be different. I suspect the answer is in the output of the 'route -n' commands I posted earlier but I'm not enough of a net admin to understand what we're looking at there.

I stupidly changed the shell of the root user to one that does not exist, and now when I try to lgon it says it cannot find the path to my shell and will not let me proceed any further. Is there any way I can get round this without re-installing the OS?

We have an OpenServer 5.0.5 system that has worked forever, but I'm hearing complaints of logon delays for users now. Normally they would telnet in and the logon screen would pop up, but now it sometimes takes a minute or more, and the user must hit the enter key to get it to appear. Everything... (11 Replies)
I'm having an issue with SSH on a server that hasn't had any configuration changes made on it in a long time.

You'd have to excuse me a bit, as I'm a noob. I really try to avoid asking questions and do research for whatever linux issues that may arise.
I am experiencing a long wait for the shell to come up when I ssh or telnet into a Sunos 5.10 environment.
It takes 70 seconds to give me... (12 Replies)
