Hi

Was wondering if anyone could help with this please?

I'm trying to sync my Distribution Point with my master server using rsync
and crontabs

but get the following error

rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at
/SourceCache/rsync/rsync-40/rsync/io.c(452) [receiver=2.6.9]

It looks like something to do with the public keys, I've generated them and
put them on the master server, so not sure what im doing wrong

or if there is a better way of doing this?

Thanks

Abz

    Here how I do it.

    from my DP to my main server I create my id_ras.pub then i push it using this command cat ~/.ssh/id_rsa.pub | ssh -l rsyncusr mainservername 'cat - >> ~/.ssh/authorized_keys' <---I do this both ways because I have the main server initate the rsync also as a backup

    my crontab on the DP looks like this 51 14 * rsync -rav --delete -e ssh rsyncusr at mainservername:"/my/casper/Share/" /dp/caspershare/

    This is a rsync between a MAC Server and a Redhat Server, should work if both redhat or both MAC

      How are you managing syncing large amounts of data from your master server
      to the child servers,

      For example I recently created an image on our master server and it looks
      like this will take for ever to sync to the child server.

      I was thinking of using dropbox as the middle man?

      Hoe are others managing this?

      I usually don't have any issues. I use the main for rsync only though. I don't point any machines to it. It's just a old g5 Server. The others are Redhat VM's

      Ok, my main is location in the UK and child in Hong Kong and I'm finding
      that large packages will take ages to upload to the child server in HK

      I'll also be deploying several other child servers to our Sydney,New York
      and Detroit Offices

      at the moment, the child servers are the ones running the rsyncs (this was
      recommended by Jamf)

      What would be your recommendation for me to keep the child servers
      up-to-date?

      Thanks

      I have a 120 buildings and 7 servers but I am blessed with fiber and in 1 city. Are your dp's linux or Mac? Rsync is pretty fast and reliable. I found it faster then http.
