Problem with Telnet, FTP to machine in LAN

Hi ALL,

I am trying to establish a mini LAN with a router connected
to internet. I have three machines connected to router. All the
machines are able to connect to internet. I have linux on two of them
and a windows machine. I am able to ping each of the other machine
with respective IP address. But the problem is i am not able to
connect to the linux machines using telnet from windows machine, even
though xinetd server [telnet server ] is running. nmap reports telnet
port to be open. But connection is not getting established. I would
like to know the exact reason for the problem.


Regards,
Madhur

/etc/hosts.allow and /etc/hosts.deny?

firewall? "iptables -L" as root to see

I would expect telnet to be more or less crippled by default as it's not
secure on the opne internet (login and password go unencrypted). Most peple
use ssh (daemon + client on linux, Putty ssh client on windows).

Can't help you, unless it's the router that blocks telnet, or a firewall
on the Windows machines?


The use of telnet is discouraged, these days, for security reasons.
FTP ditto.

If you want to exchange files between Win and Linux without to much
hassle, I'd suggest 2 solutions:
1. Create a Win share, and access it from Konqueror using smb://win_pc as
address. No install required, in a lot of distro's.
2. Get WinSCP somewhere. It will allow you to exchange files in much the
same way as ftp, but using the secure ssh/scp protocol. Again, no config
required.

Solution 1 will use allmost the complete bandwidth. Solution 2 is slow,
about 1.8MB/s in a 100Mb/s LAN, instead of 10MB/s.



Beyond that, you can define SMB shares in Linux, for the more regular
exchanges. In SUSE, Yast will do the config for you.
