FTP and TELNET not working, dont think it's inetd problem

[samd_1]

Ok all of sudden neither of these services are working on my HPUX 11.0 K machine....If I try to connect to either from a remote machine (same subnet) all I see is the cursor sitting there. Therefore it connects, there is just no response. I have tryed to FTP and TELNEt from the console and it works so these services are running. This verifies that INETD is running, correct? Haven't checked the machine in a while so I'm not sure when it stopped working. All I can think of is maybe something didn't start back up after a recent reboot...Also another Oracle instance was added recently. Maybe this is a kernel configuration issue. However Oracle is working fine. I can connect to all the instances just fine.

There's not a whole lot of info here. It could be a number of things...
Here's a few things you could check on.
1. You check ps -ef | grep inetd and it is up and running (and you have restarted it to ensure this)
2. You have confirmed it is not a bad name/ip resolution by doing nslookup on name & ip. You are sure it is not a dup ip.
3.. You telnet in and it hangs for a couple minutes before it gives you a login:
Telnets from the PCs take about 100 seconds to get a login prompt
because the K-box attempts to resolve the name of the incoming PC.
The K-box doesn't resolve it because it is not in the hosts file.
The K-box then it passes it to the DNS server, which it doesn't have
it registered either. The DNS server finally sends the usuccessful
result back to the K-box which then will give the PC a login prompt.

The way to fix this problem is to make entries in the named.boot file
on the DNS server for each leased IP that the dhcp box serves out.

Note: Restart named.

It doesn't matter what name he gives for the alias of the IP, it
can be pc1 through pc100, if there were that many boxes. Next time
the pc telnets, the DNS box will have a successful lookup and the
login prompt will appear much faster.
4. You may want to double check that rpcbind was started properly: Check the last entry of this thread:

5. You may want to make certain your special files are ok.
Rebuild the special device files at the command prompt as follows:

insf -d ptys -n 512 512 being the number you set NPTY in SAM (10.20 and
11.0)
insf -d ptym -n 512 (10.20 and 11.0)

insf -d pts -s 512 -e -v (for 11.0 only )

That's it, your sessions have been increased to 512.
6. Ensure that /var/adm/inetd.sec hasn't somehow been set to deny ftp &/or telnet privileges.

Just a couple thoughts,
Rita

As soon as I corrected my IP in the hosts file on the K I could connect. It wouldn't wait a few minutes like you said. I know that my IP had changed recently but I know before that I didn't have to have a machine in the K's hosts file for telent or FTP ro work...hmm..I'll read me what you mention.
