Red face not able to get ftp access to aix 5.2 from windows pc


i got a new rs/6000 server with 5.2, ftp is not working when i try to connect from windows pc. but i am able to use ftp in the p615 server to get files from others. i believe some security enhancement in 5.2 is stopping me. anyone can guide me please.

There's no specific security enhancement, but it sounds like ftp is disabled on your server.

1. Look in /ec/inetd.conf for the line "ftpd". Check it is uncommented, and uncomment it if not. Then type "refresh -s inetd".
2. Check the file /etc/ftpusers : the user you are trying to connect as must not appear in this file.
3. Check that you can connect using other means from your PC to the server (e.g. telnet or ssh).

Sounds like either your PC or the AIX server is having some sort of network slowdown. Could be a routing issue (try using traceroute to check). Could also be a DNS problem - e.g. the server trying to do a DNS lookup when it can't access the DNS server - check in /etc/resolv.conf.

If FTP is working from Reflections but not the DOS command line, that suggests that part of the problem might be on the client (maybe they have different default timeout settings, or something like that).

Johnypat, first of all have a look at the hardware connexion.
issye the command
ping <ipaddres>.
Let the command run a couple of seconds and stop it with Ctrl-C.
The command should show some packets sent, some packets received, and no packets lost. And also the time for each packet should be 0 ms or 1ms.
If not, you have physical layer problems (hardware problems), and then you have to check your Ethernet cable, and/or all the cables between your PC, the switches, and the AIX box.

I just experienced the exact same symptoms with telnet and ftp to our AIX servers (5.1).
Found out we lost the DNS server that was configured in resolv.conf.
Changed nameserver entries in resolv.conf to a working DNS server and everything is fine now.

I'm still trying to figure out why DNS is involved when I was using the IP address to FTP.

I also experienced something very similar to this in which DNS was the culprit.
