It is worth a try to use the 10.x.x.x network. Systemimager-rsync is just fine for small clusters and is the default. Systemimager-multicase and systemimager-bt are for different, more scalable transfer technologies (multicast and bittorrent respectively). rsync is the simplest of the three and since you are having problems I would stick to that until you resolve the networking issues.
Removing the # in the sshd.conf file should be sufficient. You might need to restart sshd, but I don't remember. That is probably not your problem though, that would just cause problems later when you were trying to run programs on the cluster. You mentioned hosts.allow. That isn't a firewall exactly and generally oscar doesn't deal with security using those files. What do you get if you do 'iptables -L' as root on your head node? It should say something like this: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination On Thu, Oct 30, 2008 at 12:10 PM, ali nazemian <[EMAIL PROTECTED]> wrote: > Yeah , i tried YUOK before . > I saw most of them with 192.168.1.1 ip address , but this time i use > 10.10.x.x for network ip address , may be this can help me fix the problem. > and FYI the switch is 4210 , 24 port 3com. > I have 2 question about that , in step 6 , i can choose between , > "systemimager-rsync" , "systemimager-multicast" and "systemimager-bt" what > is the diffrence between them?! > also for configuring ssh, as it written on installation guide i should > change "PermitRootLogin" to yes. for that i just search for > "#permitRootLogin yes" line and delete "#" from its head , that is it? is it > enough?! > cheers. > > > On Thu, Oct 30, 2008 at 6:33 PM, Michael Edwards <[EMAIL PROTECTED]> wrote: >> >> There is nothing magic about clustering for your switch to support or >> not support.
