Thanks. I traced DNS and sure enough when an ftp client connection came in I saw the server request a lookup on its own local hostname (not sure I understand why it would do this, I was expecting to maybe see a reverse DNS on the client address). Anyway, I added the local box to its own /etc/hosts and of course there is no longer the lookup on the connection, so if it is a DNS issue with my provider hopefully this will work around it. mk ----- Original Message ----- From: "Matthew Emmerton" <matt@gsicomp.on.ca> To: "Mary Kay" <mkay1971@hotmail.com> Cc: <freebsd-questions@FreeBSD.ORG> Sent: Thursday, October 11, 2001 12:13 PM Subject: Re: Problems accepting TCP connections > > Hi, > > > > I am trying to setup a FreeBSD box to serve as an anonymous ftp server. > > Everything works well, but at some point (8-12 hours or so) I start having > > unexplained problems with connectivity to the FreeBSD box.
