I hope someone can help me with a strange problem.
I'm running a MacOSX Server, v 1.0.2, iTools, PHP3, ftp, telnet, MySQL,
htDig. This setup has worked very well for over a year.
Background: Our network people completely rewired our building with a 10/100
network. When all cables were pulled and new ports installed next to the old
ones, they checked each port, then cut over to the new network at one time.
As a result, our IP addresses changed. We switched to a DHCP setup, with
fixed IP being controlled by the DHCP server with a reservation for a
particular IP. This seems to be working just fine.
The Problem: FTP connections and some PHP scripts delay for 60-90 seconds
before completing. I can ftp via command line to the server and it shows
"connected to server" immediately but waits 60-90 seconds before showing the
login prompt. Once that prompt shows up, the connection seems to be just as
fast as ever. The same thing happens with a couple of form submission
scripts I wrote in PHP. Click Submit and watch the watch roll for 60-90
seconds, then the confirmation page appears.
To add to the weirdness, I can't ping our DNS server from my server, but I
can from my workstation, and they are on the same subnet. If I ping my
server from my workstation, it works. If I ping from my server to my
workstation, it works. If I try to ping outside my subnet from my server, it
doesn't seem to work.
I've checked NetInfo for the IP change, and it's correct. I've gone through
each configuration page (apache, iTools, ftp, inetd, etc) and the only thing
that has changed in any of them is the IP address.
Why would this change cause such odd behavior? Remember, there was not a
single problem like this before the IP change.
If anyone has any ideas at all, I'd be very grateful. Even if you could
point me to a reference or give me questions to ask our network folks, that
could help me out.
