I have a sparcstation with sunos 4.1 at home. I also have a NT maskin that I connect  to internet with throw a modem.
How to I do to get the sparc to use the proxyserver on the NT maskin so I can telnet and ftp directly from the sparc.

Do you have any network connection between the NT machine and the sparcstation? What do you really mean with proxyserver? In my understanding a proxy-server can't be used for telnet.

Yes I have a network connection between the NT machine and the sparcstation.

On the NT I have a proxy software running. I can telnet on my Win95 machines through the proxy on my NT server. But how do I do to get the sparc to use the proxy ??

It is the client (telnet, ftp, web browser), which must have the ability to use a proxy service. For example you can configure the Netscape browser to use proxies (also for FTP). And the ftp command of the SunOS can handle proxy requests (you ftp-connect to the NT machine and then you enter e.g. "proxy open <remote-machine>". However this is uncomfortable and you better use netscape or look for public domain software.

Concerning telnet: although the SunOS telnet command doesn't support proxy connections, you can try to give the portnumber of your proxy services ("telnet <nt-machine> <port>"). Maybe this works, but I doubt it.

What you really need is a routing or gateway software for the NT server. Then you configure the SparcStation with the command

route add default <nt-machine> 1

to send all outgoing traffic to the nt-machine, which will forward them via the modem to the internet. However, this will only work if the nt-machine also propagates that it can deliver packages back to your SparcStation. It must therefore become an active router.

In case we will go into further discussion, here are some questions: what kind of identification do you use within your LAN? Do your Win95 machines have IP numbers? Do you have a subnet? Can you anyhow connect from the PCs to the Sun (telnet or ftp) and viceversa? What kind of ISP do you use, what restrictions does the ISP imply? Do you have a fixed or dynamic IP-address?


Hope this helps,

Peter
