SuSE 8.0 ftp & telnet problem
I have a new HP 750n computer with a fresh SuSE 8.0 professional install. It is connected to my home LAN then to a Linksys router/dsl to the Internet. Also on this same network is an older computer running SuSE7.3. Both of these computers have access to the Internet and work very well. My problem: I desire to ftp, xftp, or telnet inside my LAN from one computer to the other for the purpose of using the older computer as a data storage device for backup of data from the HP machine. Here is what works. I can ftp or telnet from the HP (SuSE 8.0) computer TO the older (SuSE 7.3) computer but NOT from the older computer to the HP. I can ping both machines from one to the other. Eliminating the router/dsl leaving only the local LAN does not solve the problem. Both machines have ftp and telnet turned "on". Both machines have the command rcinetd start initiated as part of the boot sequence and "TOP" shows them running. The error messages I see when attempting to connect FROM the "old" computer TO the HP are: telnet 193.168.1.100 (address of the HP computer) "connection closed by foreign host". When I try the same command with ftp I get "421 Service not available, remote server has closed connection". If I go from the HP to the old computer everything works. By the way, substituting the correct name (harry) instead of the 192.168.1.100 causes exactly the same error messages. I have read everything I can find searching SuSE support, info pages, man pages, and google search but nothing I try will make it work. After two weeks of trying to solve this on my own, It is obviously beyond my comprehension. Can anyone help or point me in the right direction? Thanks in advance... Harry Wert Physicist

From what I see in my /etc/inetd.conf, telnet services are handled by tcpd these days. man tcpd informs me that it uses the /etc/hosts.* files for access allowance/denial. As far as I remember, SuSE 7.3 did not used tcpd (but I could be wrong, it's been a while:). Perhaps tinkering with the /etc/hosts.* files will get your telnet/ftp up and running? Hope this helps, Pieter

Have you checked the firewall settings on your 8.0 machine? Do you have telnet and ftp daemons installed on that machine? I don't think that either telnetd or vsftpd are installed by default, so you might want to check on that. Have you tried using ssh? Is sshd installed? Kevin

Some points to check: 1. inetd.conf (or xinetd.conf) if ftp or telnet is enabled 2. if these programs are available 3. if there is a hosts.* file that cause the problem 4. if a firewall rule prohibits the access Good luck! bye Ronald
