Connection timed out

Hi,

It's been a while since I've been using SABnzbd. I was setting it up earlier today, but I can't figure out why it doesn't start downloading.

Version: both 0.7.14 and 0.6.15
OS: Debian 7.1
Install-type: Linux repository
Firewall Software: iptables (not the issue, had it disabled)
Are you using IPV6: No
Is the issue reproducible? Not sure

The issue is as follows:

Whenever SABnzbd starts to download it connects to the newsserver, hangs for 120 seconds at the first article and then times out.

Code: Select all

The only thing I haven't tried so far that comes to mind is changing the newsserver, but I recall it working perfectly fine in the past, using the same newsserver.

I appear to have solved the issue by lowering the MTU. If someone ever gets the same issue and comes across this thread, execute this as root:

Code: Select all

/sbin/ifconfig eth0 mtu 1492
If that solves the issue, then make it permanent by adding

Code: Select all

 mtu 1492
to the bottom of

Code: Select all

/etc/network/interfaces

1492 is the default size for just about any system. Does Debian use a different default?

The default MTU for Ethernet is 1500, the default MTU for IEEE 802.3/802.2 is 1492. Debian somehow managed to set the default MTU of Ethernet rather than the IEEE 802.3/802.2 default.
