Linux Telnet & FTP

[Hawki]

Keep in mind I have never done this before and all of the books I have read act as if the information I need is a big secret. I need help in configuration, Red Hat 7.1, of three areas:

1. Telnet: I need this so I can telnet to my Linux server from an NT server. I can ping the Linux server but can’t telnet to it.

2. FTP: Need to know what steps I need to take to make it work.

3. After connecting to the Linux server can I start an x-windows session via a telnet session. Also I have Hummingbird 6.1 software. How do I configure it so I can use it to work with Linux from NT server.

starting up with using telnet is a simple change of the

/etc/xinetd.d/telnet

file. There is a line that says

disable=yes

which needs to be changed to

disable=no

.

However, you would be better advised to leave telnet off as it passes information across your network in clear text format, and to use SSH... RedHat 7.1 comes with a OpenSSH server and client software installed, and there are multiple Win32 apps out there that support SSH. I use SecureCRT from

FTP is similar as well, but you need to ensure that your installation has installed a copy of WU-FTPD (the default FTP server with RH7.1). As long as this is installed you should be happy...

I am not sure to the answer to the third question... I use SSH, SecureCRT and the X-Win32, and this has always worked for me properly.

Hope this helps.

Hi,

With Redhat 7.x you probably need to do two things : (i) activate the xinetd server(s) - as above you can edit /etc/xinetd.d/telnet & /etc/xinetd.d/wu-ftpd to change 'disable=yes' to 'disable=no' or rather simpler you can just do '/sbin/chkconfig telnet on' & /sbin/chkconfig wu-ftpd on' which does the same thing for you. (ii) make sure the redhat firewall is not stopping you - enter 'lokkit' as root and follow the screens to allow ports 21 (ftp) and 23 (telnet). Out of the box the FTP server should allow logons using existing linux userids. If you want anonymous ftp or a more secure setup theres more to it...

For exceed, I can't check right now how mine is configured but it can definitely be done. You have to do 'xhost +ntbox' on linux as the user you are going to connect as. Then its a matter of configuring the exceed client. Have a look at -->
