Telnet error

[mgrun]

HI All

Does anybody know what I must do to get rid of the following error when I telnet:gethostbyaddr: No such file or directory

This is the output of my telnet command

root@lotus ~# telnet red 13782
Trying 172.17.30.1...
Connected to red.
Escape character is '^]'.
gethostbyaddr: No such file or directory
Connection closed by foreign host.

Thanks

Hi mgrun,
Are you attempting to telnet to red on port 13782?

Try using the command "telnet red" or "telnet red 23"
OR "telnet red.domainname" "telnet red.domainname 23".

Hi

Telnet on port 23 works ok. I have a problem with an application that uses that port

A colleague offers;
This might be due to the "corrupted" telnet device files. Try to recreated them, see if it helps ..
# cd /
# rm /dev/pty/*
# rm /dev/pts/*
# insf -e
# cd /dev
# insf -d telm
# insf -d tels

What does insf do?
I am using solaris 8 and I couldnt find that command

Dang, it's an hp-ux command "install special files"....

I'm not sure, but they might get recreated at boot.
You could make a backup copy and see if a boot recreates.

I will try it later, since I cant reboot the machine right now.
I will update you.

Micha,
I think (but I haven't used Solaris in four years) that you have to create an empty file in / to create device files.

Maybe it's called /configure but I'm not sure. Devices won't be created without it. (Unless they changed it).

Nearly right, Henrik. In fact, Micha needs to create an empty file called reconfigure in the root directory. An alternative is to boot using boot -r from the OK prompt. Cheers.
