well
here at the university we have a unix box (server)(it runs RH7.2) and we telnet to it.
the other machines run win2000 pro.
my machine sees all the machines on the network but not the linux server.
and thats whats giving me headache
any one who can help ?
cheers
are you using the "tcp/ip" protocol if so you have to be able to ping to youre server.
try this at command line
>ping server
where server is the name or ip address of the linux server.

You should try making sure it is connected to the network. Can any other box see it? Can the GNU/Linux box see the network? And is the Win 2000 box connected also? What have you tried?
By see I hope you don't mean listed in "my network places" as that will not happen unless the linux box is running SAMBA, or something similar. If you can ping the machine by IP (or if there is local DNS running by machine name) then it is on the network. All you have to do at that point is type telnet {machine/ipaddress}.
well the ping doesnt run
the other 2000 boxes in the room can see the server, and my machine can see the other 2000 machines (therefore its connected to the network)
we are using the tcp/ip protocol.
cheers
check to see what kind of file sharing is set up on the RH box.... if your not equipped with a configured package your not going to see it in network neighborhood.... as far as not being able to ping it but being able to telnet in your most likely dealing with firewall software, check the config of that as well as samba or some similar package may be running but the ports themselves could be blocked.
best of luck
Hi,
Have you check on Linux server DNS configuration I think you need to add your machine "name" to your Linux Server DNS configuration, so you can do telnet to it.
It's mean no communication between your comp and your serverQuote:
well the ping doesnt run
Just my opinion though..I could be wrong
Cheers
Check what subnet the server is on, you are on and also the network 2k box's, they are probably all on different subnets and access is only allowed to the server from the w2k subnet.
Did you ping it by name or by numerical address? If you can successfully ping by
numerical address but not by name, then the name isn't resolving into an
address. Since only this one machine can't see the linux server, I'd guess you
either aren't accessing the DNS server (if there is one), or your hosts file needs
an entry naming the server. Look in c:\winnt\system32\drivers\etc\hosts.
I may not have that path right for your system, but it's something like that
You see addresses, followed by names.Code:# Copyright (c) 1998 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP stack for Windows98
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
192.168.0.1 rcgreen
192.168.0.2 stacy
192.168.0.3 acer
This is absolutely essential if the network doesn't have DNS.
:cool:
Well , first make sure that you can ping the server like said before.To be on the safe side make sure that the telnet service or whatever service your trying to connect to is open and listening , cause it would kinda suck spending headaches on a simple problem.

When you say that the other 2000 boxes can see the server, what exactly do you mean? Are you saying that they can see it in Network Neighborhood, or are they just able to ping and telnet to the server? I think that part needs to be clarified for us to help you more. Also, maybe you could give us an idea of what else is running on the Linux server???Quote:

We'd like to help, but give us more information if you can.
another suggestion to add...
try and ping the box you are having trouble with FROM the server as well as pinging to the server, if your server can ping your box it still could be a server issue, do you have a firewall enabled on the 2k box at all?
2 firewalls can cause hell with this kinda setup, so that could also be a problem, the firewall on linux could be blocking your machines ip as well, could really be a number of things but these 2 are the most common
Without speaking to your original problem, when you are able to telnet in, you'll want to (seriously) consider cutting over to OpenSSH, testing it, then shutting off telnet. It's insecure.
