telnet question

Ragni Singh — Wed, 03 Apr 2002 17:49:10 GMT

Hello, I'm trying to telnet to a SCO server and giving me connection refused message. The server is up and running and we are able to ping to it. I do have the the routes added as well. I'm not understanding why I'm not able to telnet to this box. Any help will be greatly appreciated.

Not having a SCO server in five years, I can't exactly tell you how, but what you need to do is set up telnetd on your SCO box to allow you in. Hopefully you have another way to get access to this box.

On your SCO box, in root, put a "+ +" in .rhosts file, then try rlogin, just to test the routing. Then of course remove the entry, lest you want everyone on your network to be able to login as root.

Sanman,

If you are able to ping to the server and if you are still getting refused messages, I could think of any of the following reasons.

1. inetd is not running on the server
2. There might be tcp_wrappers/inetd.sec configured on the server that is blocking your IP/network to connect to.
3. May be firewalls in between that are filtering the TCP traffic.

You should go to your SCO server and ensure that telnetd is running. A lot of SCO installations prior to 5.0 did not have the TCP/IP stack included, so there is a good chance that there is no networking there at all. This was common when dumb terminals were used instead of networked PC's.

See if you can telnet from the SCO box to your HPUX box.

Most importantly, drop the SCO and install LINUX!

Go to console, verify telnetd is running, if not start telnetd (not sure about syntax of this in SCO)

Hi Sanman,

You need to login to the SCO server & ps -ef | grep telnet to detrmine whether the telnetd daemon is running.
This is one of those times where I wish HP-UX could ping a port as AIX can do .

Rgds,
Jeff

Login to the SCO server at the console and telnet to the same machine. If it works, it means there's a routing / TCP-IP / firewall problem.
If not, telnetd is probably down.

Do all users have a problem telnetting to the SCO box or is it only a few of them?

We are using the SCO just to run the enguard application and noone but myself really needs to get to it. Teh only thing I can do for now is to run the telnetd daemon in debug mode. It seems the telnet daemon refuses to run. When I do a ps -ef on telnetd, it doesn't seem tot be running either. I'm a HP-UX fan myself but since operatons staff uses enguard to monitor some systems, we have to have SCO running. I can do things when I'm directly logged in through he console but but need to be able to telnet to if needed. Thanks for all your help.

hi,

What does the syslog messages in SCO box show ?? Corresponding to every telnet attempt , there should be a message logged in the syslog giving the probably reason for failure.

telnetd is called by inetd; So, i am not sure whether you can run it standalone. The problem may not be with telnet, but somewhere else. Is ftp working? Is rlogin working? Can you telnet from another system to the SCO?
