Why tcp sockets for dashbaord?

[msevior physics unimelb edu au]

Hi Folks,
         I just this question in the abiword bugzilla about dashboard.

Any clues?

Thanks!

It appears that the dashboard uses tcp sockets and quite regularly.  With a
misconfigured firewall this can cause serious slow downs in Abiword as the
input
is filtered by the kernel.  Iptables rules which look like the following are
doing the damage:

iptables -P INPUT DROP

If the administrator or user does not remember to enable INPUT on the
loopback
interface after such a rule.  Therefore, enabling INPUT on the loopback
interface such as like:

iptables -A INPUT -i lo -p all -j ACCEPT

will resolve this issue.  As will removing the dashboard.

Here's the question though:  Why does the dashboard use TCP sockets
instead of
UNIX sockets?  Using UNIX sockets would resolve this issue even with a
misguided
firewall configuration.
