Can't telnet to SCO

[Guest_imported]

I'm new to SCO, had some settings to enter from a software provider. After doing that and rebooting I can't telnet to the SCO machine. I still can ping the IP address though.
Any ideas what to look for ?

The commands were:
# ./idtune -f SEMMNS 750
# ./idu tune -f SHMMAX 16777216
# ./idtune -f SHMMNI 500
# ./idtune -f SHMSEG 15
# ./idtune -f SHMALL 1000
# ./idtune -f ARG_MAX 30720
# ./idtune -f SFSZLIM 0x7FFFFFFF
# ^[ 
# ./idtune -f SFSZLIM 0x7FFFFFFF
# ./idtune -f H
# ./idtune -f
# ./idtune -f HVMMLIM 0x7FFFFFFF
# ^[ 
# ./idtune -f HVMMLIM 0x7FFFFFFF
# ./idtune -Sff S
# ./idtune -f LOTSFREEBYTES 25600000
# ./idtune -f MINFREEBYTES 12800000
# ./idtune -f DESFREEBYTES 6400000
# ./idbuild -B

The unix kernel will be rebuilt now.
This will take some time. Please wait.

what does the console screen say?
can you log in there?
did you cut and paste the idtune info that you posted?
there are a number of control codes embedded in it.
when all else fails, if you shutdown the unix box and when it comes up to the boot: prompt type in the following:

hd(40)unix.old

once the system boots you will have your old kernel back
then you can check the /etc/conf/cf.d/stune file for your changes.

hope this helps

Thanx for your help,
I can start the server and login to it from the console, nothing looks different.
I found out that inetd service is not up by runing
ps -ef |grep inetd

then I try to run

sacadm -s -p inetd

then I get
Can not contact SAC

Any ideas ??

Thanx

well since sacadm is a sunos utility not an sco one it would be my guess that is why it cant find it.

inetd not running:
this is a function of the tcp start script
/etc/tcp (linked from /etc/rc2.d/S85tcp)
which runs /etc/inetd if it exists and is executable.
# sd starts inetd with no LUID for
# high security systems
/usr/bin/sd inetd < /dev/console &
once inetd starts it reads its configuration by default from /etc/inetd.conf

You might want to check your /etc/inittab file for corruption if it was rebuilt when you rebuilt your kernel.

Hope this helps
