Operating Systems SCO how to give Telnet access Post 302486129 by nicke75 on Friday 7th of January 2011 05:05:34 AM

Hi, thanks for your replies.

I totally agree about SSH but in this case a program has been written by somebody who has left the company that accesses the server using Telnet and then runs some macros. This program only needs to run on a couple of admin PCs and it would be good if I can just resolve this Telnet issue until such time as we can achieve the same goal using SSH. All other PCs on the network use an SSH client to access the application running on the Sco server.

Also I would like to understand the problem. If I just go to my boss and say "Well, we should be using SSH" then, although that is true, I'm more or less saying that I don't understand the issue and can't solve it, and it should be so simple.

When I Telnet to the server from my Windows PC I get a login prompt and can successfully log in, no problems. When my colleague tries the same thing she does not even get a login prompt, just a blank CMD window with a flashing cursor which then times out. If I change her PC's IP address to the IP address on my PC she can Telnet to the server with no problems, so it is an IP address restriction.

My colleague can ping the server and access it using SSH so there are no communication issues. As to firewalls that is what I don't know about as I'm very new to UNIX. There are no firewall rules configured between the host and the server that might be blocking the connection but as to what is running on the server itself I don't know. Before I joined this forum I read about TCP wrappers but these don't seem to be configured so I'm stumped.

Cheers,
Nick

rusersd

rusersd(1M)															       rusersd(1M)

NAME

       rusersd - network username server

SYNOPSIS

       log_file]

DESCRIPTION

       is an RPC server that returns a list of users on the network.  The command prints this information (see rusers(1)).

       invokes through (see inetd(1M)).

   Options
       recognizes the following options and command-line arguments:

	      Log any errors to the named log file,
			     log_file.	Errors are not logged if the option is not specified.

			     Information  logged  to the file includes date and time of the error, the host name, process ID and name of the func-
			     tion generating the error, and the error message.	Note that different services can share a  single  log  file  since
			     enough information is included to uniquely identify each error.

	      Exit after serving each RPC request.
			     Using the option, the security file can control access to RPC services.

	      Exit only if

				  o  dies (see portmap(1M)),

				  o  another registers with or

				  o  becomes unregistered with

			     The option is more efficient because a new process is not launched for each RPC request.  This option is the default.
