hi
 You go to /etc/xinetd.d and see the file wu-ftpd. If there is any entry
like "disable yes". You just comment this line and reboot the system.

Re: FTP problems in RH 7.1

2002-03-08 Thread Dan Simoes

Thanks for the reply.  It's not quite that simple, but in replying to
your note you actually helped me work through a few things in my mind
(some sleep helped too!)

As I mentioned before, ftp is enabled and runs if I ftp localhost.
I can also telnet to port 21 on the box.

I've since remembered that ftp uses control and data ports, which is why
telnet to port 21 works.  Things I have tried are overriding DNS reverse
lookups in /etc/ftpaccess, and I am looking into some of the passive
mode configurations.

I see the exact same behavior on my home system which running 7.2.
My home box is addressed as 192.168.1.10.  On that box, I can ftp to
localhost, but if I try to ftp to the box from another client on the
network, the connection is "closed by remote host."  syslog shows only:

Mar  8 07:17:02 cyclops ftpd[1499]: lost connection to 192.168.1.101
[192.168.1.101]
Mar  8 07:17:02 cyclops ftpd[1499]: FTP session closed

The machine does not have a FQDN, is addressed as 192.168.1.10.
The client is using a DHCP address which also does not exist in DNS.
I tried adding the DCHP address to /etc/hosts and it now allows the
connection, though it is still quite slow to connect.

Should I try grabbing wuftpd source and recompiling without DNS support,
or are there other config parameters I should explore?

Thanks.
