Linux telnet Network... "HELP!!!"

[Stuart Mckiggan]

Hi everyone, im a novice with linux and ive been asked to set up a network between two linux systems using telnet, any ideas how i would go about solving the problem, any help would be appreciated, thanks, stuart

Hi Stuart,

I'm not sure how the Linux box's are connected to the network (if at all) at the moment.
In order to be able to telnet you will need to have the telnet server & client installed on both machines.
If you are using RedHat linux 7.x you can do a
rpm -qa | grep telnet
If the output is
telnet-
telnet-server-
then you have both installed, if one is missing you need to install the RPM for it (If you are using RedHat network you can just write up2date telnet telnet-server to install them both).
After you have them both installed go to /etc/xinetd.d and edit the telnet file.
Change the disable line to no and save the file.
Now in order for the changes to take effect restart the xinetd service by giving the command (under root): service xinetd restart

Hope this helps.

Telnet into Linux is discouraged. This is an
insecure protocol. If
you are on a firewalled network,
then your risk may be lower.

I would recommend ssh. Open-ssh is available for
most distributions. It includes scp (copy) and
sftp (secure-ftp).

Check the documentation at www.tldp.org.

Try ntsysv on RedHat Linux.

hi, thanks, this seems to have spread some light on the subject. But to take the problem one step further, any ideas how the linux terminal could be connected to the citrix mainframe which is run on a windows NT server through an ethernet connection, many thanks, stuart.

Stuart,

I'm sorry but I think you need to be more specific. Tell us what your end goal is and then give all of the supporting details.

You might want to think about hiring a consultant if you are not sure where you are going with this.

sorry. The end goal is to replace the Windows NT servers with Linix Servers as current reports suggest linux is a much more stable operating system and much more cost effective, rite now the department is in the experimental stages with linux and we are looking at various ways of integrating it into the current set-up if not totally replacing the current NT server enviroment completely. We use Citrix to log users on to the existing network. thanks. stuart

Hi,
If I understand your last post,
you want to connect to linux and the users should be authentified by a NT server which is running also Citrix ?
Little explanation :
If you want to use Linux as worstation like a winterm, you can do it with Citrix or Terminal Server : Ica client exists on Linux and there's also rdp client (open project rdesktop) - to avoid Citrix which is very expensive !!!!.
If the goal is to replace NT server, you should consider the services provided by these servers :
If it's just file sharing and printing, Linux + Samba can do it, authentication can be done by Linux (It may be a primary domain controler with samba)
- For all the network services (dhcp,dns,proxy,active directory, http, routing/firewalling ...) there are solutions on Linux.
- To replace Citrix, Linux is using X11 which is standard on Unix. But by this way, you cannot run any specific windows (client side) products: for example, Microsoft word cannot work on Linux without an emulator....

In fact : To use Linux as a server, you can do quite all you want,
But to use Linux as a worstation, it's really more difficult (training of users, new clients products.....)

I'm not sure I have properly answer your question, but hope that help !
regards
Benoit

thank you for the information, as the end goal will be to replace the NT servers with linux servers we are at the stage of testing file sharing and printing, and also remotely logging into the linux machine, security at this point is of no issue, i am aware that samba can be used for F&P sharing but how would i go about the remote log in to the linux system, thanks. stuart

For File and Print sharing
Samba is your solution.
Samba allows Windows domain
validation, as well as user
validation on a per server
basis. Samba can also be
you Windows domain server.

For users that need shell
access to the server, you
can use ssh for a command
line shell, or VCN for
X-Window display.
