Shutdown everything. Place system on an isolated network. Start packet sniffer (no filter). Start any services Apache depends on (e.g., a local DNS resolver). Start Apache. Send a single web client request. Watch to see if the system is sending any packets (other than the HTTP request). If so, find out why, and see if the (lack of) response is the problem. If not, the problem must be local -- database problem, maybe? Ahhhm, just curious here, but why would a web server be sending out *any* packets, including HTTP requests. Web servers *serve*, they don't request. Good policy is to have an ip[chain,table]s script which prevents outgoing http requests from web servers. If you're seeing requests *initiated* by your web server, you've got a major problem (unless it's something you specifically condone and (allowed to be) configured yourself. -- Seeya, Paul -- It may look like I'm just sitting here doing nothing, but I'm really actively waiting for all my problems to go away.

Three-minute timeout during surfing?
Howdy, all. I just upgraded my boxen to RH 7.3, and suddenly my webmail (SquirrelMail) is taking three minutes just to bring up the login page. I double-checked my httpd.conf file, and HostnameLookups is set to off, so I don't -think- it's a reverse-DNS issue. I'm stumped. Below is a snippet from an ethereal dump. Any ideas?

Have you had a chance to test it against a non-7.3 machine to make sure that it's not a problem on their end? If you're sure that it has something to do with your upgrade, do you have a set of HTTP headers from before you upgraded, for comparison?

Re: Three-minute timeout during surfing?
I'm sorry -- I wasn't explicit enough. The boxen I upgraded -were- the servers. The clients are many, and varied, but seem to all experience the same issue. Note that of the clients from whom I've heard complaints, all are behind NAT boxes, though I don't quite see how that would correlate. (I'm going to give a go from a box with a real IP shortly, now that I think of it...) -Ken On Mon, 26 Aug 2002, Erik Price wrote: On Monday, August 26, 2002, at 03:09 AM, Ken Ambrose wrote: Howdy, all.

And the apache logs don't show anything? What about a tcpdump to see if you're getting any retries?
