What you're describing sounds exactly like the issue I was experiencing. We'd see the first line of the /etc/issue and then get dropped. Most ftp clients would report an error "421 Service not available", telnetting to port 21 on the ftp server would give "Connection closed by foreign host".
I would strongly suspect that port 21 is being proxied by something between your clients and the ftp server. -Steve -----Original Message----- From: Jeff Stillwall [mailto:[EMAIL PROTECTED] Sent: Thursday, June 19, 2003 1:56 PM To: [EMAIL PROTECTED] Subject: Re: Can't ftp to one host On 6/18/03 3:21 PM, the mind of "Rigler, Steve" wrote: > Recently (this week) I ran into a similar issue.

Well, we never even get that far. By banner, I guess I really meant 'greeting'. We can't even get to the login phase. So, instead of getting the greeting, we just get the 'closed' message. Weird, weird, weird. So, no, I have no control over the ftp server. It a machine outside of my network altogether. -- Jeff Stillwall -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
