Apache Timeout directive not working

apache-2.2connectiontcptimeout

I have configured /etc/apache2/apache2.conf with Timeout 5 instead of the default 300. So I understand it should close an incoming connection after 5 seconds of inactivity.

But I make a telnet localhost 80 , wait for 5 and more seconds, and nothing happens. A netstat -na tells me the connection is still ESTABLISHED. I left the connection about 5 minutes and still nothing happened.

Any clues why Apache is not cutting the connection? Or am I misunderstanding the Timeout directive? And in that case, which one should I look for?

Thank you

You do have the right syntax -- it should be in the global server config or a vhost config.

I tested this with 2.2.11 and Timeout closed a connection from another computer and a connection to localhost after 5 seconds. Have you tried from another machine? My config is certainly different, so you may have another setting that keeps localhost connected(?)

I tested with both nc and telnet and there was no difference either.

Which version of Apache are you using? Are you certain there is nothing coming across the wire (via wireshark or similar)?

are you absolutely sure the is no iptables rule preventing tcp/3306 traffic? try this as temporary workaround:

iptables -I INPUT -p tcp --dport 3306 -i lo -j ACCEPT
iptables -A OUTPUT -p tcp --sport 3306 -o lo -j ACCEPT

or maybe your NAT rules to a little bit more than you expect them to do?

ok - your loopback is not only down, but does not have 127.0.0.1 bound to it. add to /etc/network/interfaces:

auto lo
iface lo inet loopback

and.. why on earth did you bound it to vnet0? remove it from there.

quick one-time cmd line fix:

ip a d 127.0.0.1/32 dev venet0
ip a a 127.0.0.1/32 dev lo
ip link set dev lo up

This sounds like mod_reqtimeout needs some tweaking. Take a look at the docs for mod_reqtimeout

On ubuntu 10.04, I believe you will find the configuration in:

/etc/apache2/mods-enabled/reqtimeout.conf
