RE: FTP, MASQ, certian hosts timeout
In researching this.... it looks like the servers that lag 5 minutes were
failing to do a reverse lookup for the ftp connection because of a bad DNS
setting with ATT (they had a typo). This turned out to be the problem.
Thanks!

Subject: FTP, MASQ, certian hosts timeout
For some reason, with some ftp hosts my FTPs will timeout when I try to go
to them, every single time. Other hosts work perfectly fast every single
time.
I've got two particular hosts that I work with all the time. A Sun OS box
with one ISP that works perfect. The second is a Linux box with a
different ISP that is slow.
Traceroutes to both ISPs actually show a closer and faster connection to
the linux box.
My gateway is a Debian 2.2 masq'd firewall (kernel 2.2.14).
>From my PC behind the masq, my pc will timeout going to the ISP with the
linux box. If I go to the linux box from a unix machine behind the masq,
it will say it connected to the ISP but it will wait about 5 minutes
before it prompts for a username. Once I'm connected, transfers are as
fast as they should be.
When I access both of these ISPs from home (DSL) I can connect immediately
without any hesitation from either of them.
I can ssh to both ISPs without this 5 min delay. It is specific to FTP.
Does anyone have any ideas what could be causing this?
