Re: [Oscar-users] client installations problem

Strange to me... I disabled the SElinux and unchecked the pfilter during the installation, but i didn't disable firewall. However, I modified the TCP wrapper at the server node to allow all traffic from private network. Also, when i test cluster setup, it failed at ganglia setup test, i think ganglia is just a monitoring program and it won't affect the normal function of my cluster. May i just ignore it? Or shall i download ganglia rpm and install it seperatedly?
Thanks,
Michelle

That's strange...  this shouldn't happen.  During installation of your headnode, did you disable the firewall?
 
Anyways, glad that it works now.

Does nmap localhost show that port as being opened?  How about netstat?

Yes. It is running.
[EMAIL PROTECTED] ~]# ps -ef |grep rsync
root      3525     1  0 13:11 ?        00:00:00 /usr/bin/rsync --daemon --config
=/etc/systemimager/rsyncd.conf
root      4314  4021  0 14:00 pts/4    00:00:00 grep rsync
 
Also, in my /etc/hosts.allow file
ALL: LOCAL
ALL:  .cs.xxx.edu
 
I belive it should allow all traffic from nodes within cs.xxx.edu domain, right?

Can you check to see if rsync is running on your headnode?
 
# ps -ef | grep rsync
 
If not, then turn it on by running:
 
# /etc/init.d/systemimager-server-rsyncd start

I have two NIC cards. One for outside internet, another for private network.
Thanks,
Michelle

Can you give us the output of "ifconfig" on your headnode?  Please remember to hide any sensitive IP information if necessary.  I just need to find out what your network setup is like ( e.g. how many network cards you have, ip, etc.)

Hey, Michael,
I tried the boot CD option, and the client nodes starts to install from the system image file, however, I am seeing another problem:
*******************************************************************
bla bla...
we have connectivity to your systemImager server
start_syslogd
get_boel_binaries_tarball
rsync -av 10.1.1.1: boot/../boel_binaries.tar.gz
rsync: failed to connect to 10.1.1.1 ( note: it is my server node)
connection refused. (111)
rsync: error: error in scket IO(code10) at client server
killing off running processes.
*************************************************************************
 
How may i set in the server node in order to allow all traffic from client nodes in the private network?
 
Thanks,
Michelle

Have you tried either the boot CD option or etherboot?  Occasionally I
have had problems with TFTP not working on its own, but it works ok
off the boot CD.  Etherboot can go on a floppy if CDs aren't an
option, or that doesn't work either.
