It shouldn't timeout on a slow link so long as it's still moving data.
No clue how to mirror all the necessary pages to make it work locally. I'm sure its possible but its probably one of those things where "if you have to ask you can't do it".
Thanks man,,, the issue is sometimes the plugin installation timeout,,,, then when you try to install that plugin,,,it will show you " nickname already exist " something like that,,,, Then the only way to solve this i found now is to destroy the whole plugin zfs data set and res install all the plugnin again...
I try to find a way to mirror repository,,, but looks like most of the goolge page talking about apt-mirror,,,,
