I'm looking for some multicast file transfer software. Do you have any suggestions? Must be "quickly implementable", i.e. no Tivoli or other stuff that requires a massive infrastructure. Must run on Linux. Note that I'm not looking for cloning software, I'm looking to move a bunch of large files around to a bunch of systems on the same LAN.
We ended up fiddling with uftpd, and mrsync, but ended up using mrsync. It basically used a combination of rsync over ssh to determine what needed to be transfered, and a multicast client and server to do the actual transfers. We were pretty happy with it, all things considered. We did have to do a bit of fiddling to make the firewalls allow through, but that wasn't too difficult, and once we got it done things worked well.
Probably the most impressive push we did was ~35 GB to about 170 systems in 12 minutes.
perhaps this may work for you...
A quick search in the Ubuntu package repositories gives me Flamethrower. It's developed as part of an image cloning solution, but supposedly works on its own too.
