Five minues or more to connect to e-mail provider through browser.

Tags:

Hello,

Now here's a head scratcher...

I have two machines on my local network:

-- Debian Etch with Firefox browser
-- Windows XP with Firefox browser

When I ping my e-mail provider, I get acceptable response from either system (25 ms - 75ms).
But when I connect through the browser, only the Windows system gives me acceptable response.

The Debian system takes five minutes or more to connect to log-in; three minutes or more to bring up mail from log-in, whereas the Windows system gives me acceptable response.

But this laggardly response only happens when I try to connect to my e-mail provider. Any other URL or IP gives me acceptable response.

I've updated Debian Etch; and Firefox on both machines.

I've copied the latest from my mail provider's tech help below. As you can see, not much help. And, below that, I've copied config info.

Insights anyone? Would much appreciate your ideas.

All the best,

Lloyd

I really don't have any advice I can give you, I'm sorry. If I was sitting in front of the
computer, perhaps something would pop out at me, but from what you've mailed us, everything looks
set up correct. I can't think of a reason, outside of specific routing rules, that would cause
problems contacting Mailtrust, but not all other providers, and especially since the windows
computer isn't having any issues.

As a diagnostic step, I could reccomend turning the firewall off (/etc/init.d/iptables stop),
turning off SELinux (http://www.crypt.gen.nz/selinux/disable_selinux.html), and possibly a very
small handful of other things, but beyond that, I'm kind of stumped.

Note: firewall is off in Debian Etch; selinux is disable to the best of my knowledge.

Re: Five minues or more to connect to e-mail provider through

A couple of suggestions:

1. Run Wireshark to show what's happening on the network.
2. Run top to see if there's anything hogging the CPU.

Re: Five minues or more to connect to e-mail provider through

What kind of connection is being made? Isn't there a ident or reverse name lookup going bad?

I had similar delays because my email system tried to do an ident lookup of the system I tried to connect to, and after the 30s timeout it continued.

DNS can also introduce such delays. Check your hosts.allow and hosts.deny

Are you (accidentally) using a web proxy, while you don't have (or the wrong) one?

If it's a webpage (webmail), then open a terminal, and use telnet:

telnet [ip-of-webhost] 80

If you immediately get a 'Connected' message (cursor on next line, nothing else seens to happen), then type:

GET /
[enter]
[enter]

To simulate a http request. You should get some response quickly.

If the 'Connected' message takes a long time, there is something wrong in your network setup.

I can be more specific if I know what kind of connection is slow.

HTH,

Marcel
