RE: [uml-user] Speed problem starting brctl

[Brian E. <be...@sa...>]

As far as the public IP addresses are concerned, the external Ethernet
device is plugged directly into a ZyXEL cable modem with a built in 4
port switch. On the private side, the internal NIC is plugged into a
PowerConnect switch. We have a block of 5 IP addresses assigned. Was
there anything you were able to do with your co-location's switch? As
per Tim Doyle's suggestion I will run tcpdump and try to see what
exactly is going on then. Is there anything specific I should be looking
for?

Thanks!
Brian

Four hours sounds like a MAC-address-table timeout value in some
switches.  How
are you connecting everything together?  I assume these are multiple
public IPs
assigned via Road Runner?  Perhaps it's a timeout value on their end.  I
have
similar issues with my co-location's switches, if the MAC address of an
UML
changes.
