FTP problem

diudiu_1 — Wed, 25 Oct 2006 19:37:12 GMT

I have a Hpux server,Named A.And there is another Hpux server Name B.
I can ftp and rlogin from A to B.
But I can't ftp or rlogin from B to A.
while it's error message:
ftp(B to A): 421 Service not available, remote server has closed connection.
rlogin(B to A):rcmd: Lost connection.
I(B)ping server A,It's no problem.
And I tried to use 'inetd -l' on server A.
Nothing appears.
How could I solve this problem ?

Thank you very much.

It sounds like the services may be turned off on server A. Check /etc/inetd.conf and see if the lines for FTP and the R* commands are commented out. If they are then those services are not usable. If you need them, remove the '#' characters from the beginning of the appropriate lines. Then do an 'inetd -c' to have inetd re-read inetd.conf.

Thanks, But I checked the '/etc/inetd.conf' again just now, and 'inetd -c'.
there is nothing happend the same.
But I can 'telnet' to the server A ,from windows system(My PC),and also Ftp works well from my PC to server A.

But only unix system are all failed to 'ftp' and 'rlogin' to sever A.

Tnank you.

Hi!

Try ftp -v Host A
and post the output here.

Can you ftp rlogin from A to A? If not, then make sure there's a listener. Try to compare inetd.conf of host B and A to see what may have been missed.

Hi, all.
I can 'ftp' and 'rlogin' from A to A.No problem.

And also use 'ftp -v A', the same error message appears.

Check for a /var/adm/inetd.sec file and see if that is restricting who can access your system.

You can specifically allow or deny certain hosts access to your machine via this file.

Check on both A and B if file /etc/hosts.allow exists. If so, you should configure it to allow access from B to A.

Thank you very much.
I forget to edit file'inetd.sec'
It works well now!
