Linux client via MS Proxy Server

[wing]

Hi All,
I use a RedHat7.1 Linux system in a Windows NT LAN. The NT server runs MS Proxy Server 2.0 and it offers HTTP, FTP and Telnet services but no Socks. All the computers in the LAN. must access Internet webs via the proxy server. In Windows2000 I can browse the Internet with IE through the proxy server but I fail again and again when I try Mozill or Netscape or Konqueror in Linux even after correctly filling the informations such as IP address and Port number of the proxy server. Take Netscape for example, at Edit-->Preference-->Advanced-->Proxies, I fill the IP of the proxy server 192.168.167.3 (inner IP in the LAN.) and Port 80 just like those in Windows. But when I give a URL to Netscape there is no response for a long time. It is said that if your proxy server is a MS Proxy Server you can access the Internet only in Windows environment only with IE because there is no Client of MS Proxy Server for Linux. Is that the truth? Please do me a favour and any assistance will be greatly appreciated.

Id you have a dhcp server runnung try setting the nic on the linux box to use dhcp to get all the info. You nic needs to know the dns server's IP address. if you don't have a dhcp server, on one of the win boxes goto the command prompt and type ipconfig/all and use that info to set up your linux nic.

Yeah, that's a good point. Make sure your network card is setup correctly. Can you ping 192.168.167.3? Can you ping the IP address of www.yahoo.com (http://www.yahoo.com) (64.58.76.178)? Can you look up the IP address of www.yahoo.com (http://www.yahoo.com) in a DNS server (nslookup www.yahoo.com)? (http://www.yahoo.com)?) (Note: the two IP addresses may be different because Yahoo! has a lot of web servers scattered about)

I am sure that I setupped the Earth Card and DNS correctly. I can ping 192.168.167.3 and any other machine in the LAN. When I ping www.linuxnewbie.org (http://www.linuxnewbie.org) I get a response like "Ping www.linuxnewbie.org (http://www.linuxnewbie.org) (63.236.73.208) from 192.168.167.198: 56(86) bytes of data." but all the packets transmitted from 192.168.167.198(the inner IP of my machine) are all lost. It seems that my system administrator makes that impossible, maybe for the security reason. But I am sure that the HTTP port (80) of the proxy server is open. Is it the problem of MS? Windows vs Linux, IE vs Netscape, too many stories.

It is possible that you can only use MS proxy server with IE. That would be very stupid, but MS does stupid things all the time. What happens if you try to telnet to port 80 of the proxy server?

I would ask the proxy server admin about it, if you can.

telnet 192.168.167.3 80 and it returns something like
Trying 192.168.167.3...
Connected to 192.168.167.3.
Escape character is '^]'.
Then the cursor stay in the beginning of a new line flashing to wait for input. When I send a command "GET HTTP/1.0" it returns an error code 500.

It seems that I cant pass the user authentication. I use the username and password in Linux just the same as those in Windoze but the server doesn't seem to recognize them. So I believe it is the problem of MS. To confirm that I downloaded a copy of Netscape (version for Windoze) and installed it in a Win2k box. What I got then? It really didn't work at all! Is my Linux foredoomed to be a lonely penguin in a isolated island?

I hate to say it, but this is about the tenth time I've seen the Linux through MS Proxy question, and well, I've never seen nor found and answer. MS Proxy 2.0 should work with any Cern complaint browser, but it dosen't. Also, you should be able to use the socks client with the socks server on MS Proxy to access www, but well, no one can get that to work either. I've heard that you can use MS Proxy to allow remote access to a Unix box on your LAN, but have never heard anyone successfully using it to allow a Linux client to browse the net. I suspect MS authentication to be the problem, but I have also heard that there is an incompatability between the socks 5 client and Proxy 2.0. Maybe SAMBA would help to atleast get the box on the domaim, but I'm not sure as I have never tried it. If anyone has the answer to this one, I'd be glad to hear it too. :( :(

So there is no hope? Damn it! There are so much proxies for choice, why just MS Proxy Server? Just like what you said, I searched this topic with the engine of google.com and found some informatinons but NOOOOOOO answer.
I am so disappointed.
