synchronize portage files in a LAN

hi,

I have 7 computers in local network and I want them to have always the same
portage files (the ones synchronized with rsync). of course I can use
crontab to make them sync at a specific time but I'm wondering if there's a
better alternative. I saw a wiki page which says to create one local rsync
server and have the other 6 computers synchronize with it (by pointing the
SYNC variable to the local rsync server). but I also thought NFS could be
nice: I just have to sync one machine and everyone will always be
"synchronized".

what's the best approach for this case?

thanks!

The options you mentioned is the best...Just settup the rsync server on the machine you want it on and then setup a cront job to update it daily. Set your 6 hosts to use your local rsync server machine and create cron jobs for the 6 machines. Just make sure that their cron jobs are 5-10 minutes ahead of when the local rsync server updates it's files.

I think either way would work. The bad thing about a NFS is that you
have to run emerge --metadata to update the files in /var. I think this
is still correct. I always synced to my main machine. It is easier in
my opinion. I seem to recall having to uncomment one line in the config
file and start rsyncd. It worked.

My thoughts at least.

Slow network or WLAN? Use a local rsync server. There is a package for
this (app-admin/gentoo-rsync-mirror) and instructions on the net.

While you are at it, you could also install an http or ftp proxy for
distfiles. net-proxy/http-replicator should do it if you do not want a
complete proxy infrastructure.

>=100MBit connection? Use NFS. You should not only put your portage tree
on this but also distfiles and /var/cache/edb. Do not do this with
/var/db/pkg, however.

Hope this helps
