FTP: Connection closed by remote host.

[Yan Berube_1]

Hi all,

If I try to ftp my hp-ux server ( 11.11 ) from any other hp-ux hosts, it's working fine, but if I try to ftp it from wintel hosts, i always get connection closed by remote host ( same if I'm using hosts or ip. And msg in syslog.log is not giving me more information ( ie.: Ftp connection closed. ). Is someone able to help me, plz ?

inetd.conf :

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -a -l -u 000

No inetd.sec in /var/adm.

I already try to do inetd -c and inetd -k.

Telnet is working fine...

I don't know where to look now, can you help me, plz ?

Yan,

Make sure your wintel machines have IIS installed, and ftp configured.

Hi,

I'm not trying to ftp a wintel ftp server, but trying to ftp an hp-ux ftp server from a wintel wks.

Thanks !

Hi,

Are you making use of ftphosts (/etc/ftpd)?
Are you using IPFILTER?
What does your logfile say?

/var/adm/syslog/syslog.log
/var/adm/syslog/ftpd.log
/var/adm/syslog/xfer.log

Do you have a long delay when connecting to the host? Try adding the client IP to the /etc/hosts table.

Here is the content of syslog.log:

Jan 17 06:28:17 catia20 ftpd[3440]: FTP session closed
Jan 17 06:28:30 catia20 ftpd[3371]: FTP session closed
Jan 17 06:31:23 catia20 ftpd[3446]: FTP session closed

Hi Darrel,

I didn't used ftphosts file in /etc/ftpd.

Hi Ivan,

Seems to work now, if I add hostname in /etc/hosts. But why, i need to do that ? It was working fine few days ago without this entry. Need to find where the problem come from, don't want to add all wintel hosts in /etc/hosts.

thanks !

Look in the syslogs on the Unix Server and see if it says that the connection was blocked. It may refer you to the rule as to why it was.

My problem seems to be related to a DNS issues. Waiting answer from DNS team, before closing down this ticket.

Thanks all for your help.

Normally, name resolution should be consistent for your services to work smoothly. If you have done some modifications to the DNS configuration of your server, or the /etc/nsswitch.conf file, you will see this behaviour.
