I am building a new server. It will be a temporary firewall of sorts.
I am well into the config, made a lot of changes; almost ready to set it up in the target networks, but now....
The system hangs trying to start sendmail. I was thinking hard about disabling sendmail, but thought I needed it for internal functions, so did not. yet.
So is there someway to get the system working so I can change something like disable sendmail?
The system has no cdrom, diskette, etc. In fact the kybd/monitor require a special temp setup. Perhaps I can edit the kernel line in grub to disable something?
If necessary, I can pull the drive and put it in a system that does support cdrom. That is the way I did the initial harddrive install.
At startup, you will see a message that say Press I to run in interactive mode, there you can reject starting sendmail when you are prompted.

Now this is something to add to my Linux support/admin notes.
THANKS!

Make sure that the system has an entry for itself in /etc/hosts. This will allow the system to boot up even if DNS is unavailable.

It was there, but the host name only. Not the FQDN. I KNEW that....
Ya know, it really doesn't help knowing the insides of all those RFCs. The time sitting with Vixie, Mockapetris and others at an IETF bar. When it comes down to it, you just have to do the work and dot those Is and cross those Ts.

sendmail is waiting for dns resolution of its hostname/name. Fix that and it will not 'hang'. Or just wait for the dns queries to timeout (could take a while...i cannot remember...5 mins?)
