SSH keeps disconnecting
I connect to one of my linodes using PuTTY. It keeps disconnecting, usually after a few minutes. This can happen when a command is running, or when nothing is happening.
Any ideas how to keep it connected? It doesn't happen on my other linodes.
Thanks.

@obs:
Does it say why it's disconnecting? Check your logs in /var/log for errors.
There's nothing in /var/log/messages except:
Aug 3 08:04:19 li90-235 syslogd 1.4.1: restart.
I just turned on keepalives in PuTTY and will see if that helps.
What makes me suspicious is that my other linode has never had this issue. The main difference between them is this linode has multiple IP addresses, and my guess of the day is some configuration to do with this could be wrong. I've noticed when loading my munin graph page, sometimes a graph won't load, so perhaps some connections are getting mashed?
I'm using CentOS, and configured three scripts in /etc/sysconfig/network-scripts
cat ifcfg-eth0
# Linode Host Network Adapter
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
IPADDR=74.207.248.235
NETMASK=255.255.255.0
GATEWAY=74.207.248.1
cat ifcfg-eth0:0
# Linode Host Network Adapter
DEVICE=eth0:0
BOOTPROTO=none
ONBOOT=yes
IPADDR=173.230.155.74
NETMASK=255.255.255.0
GATEWAY=173.230.155.1
cat ifcfg-eth0:1
# Linode Host Network Adapter
DEVICE=eth0:1
BOOTPROTO=none
ONBOOT=yes
IPADDR=74.207.250.169
GATEWAY=74.207.250.1
NETMASK=255.255.255.0
Anything glaringly obvious, like I shouldn't have set gateways/should have etc?
Many thanks.
