Hi,
When I installed the OSCAR in the CentOS 5.6 I obtained a similar error:
"Head private IP:
Cannot update hosts without a valid ip.
ERROR: Impossible to update the headnode NIC data at
/usr/bin/oscar-config line 315"
All was configured right. The IP address, hostname and others
configurations. I noticed that the IP address don't was obtained.
When I read the file
"/usr/lib/perl5/vendor_perl/5.8.8/OSCAR/Network.pm" I found the
following fragment code:
open(IFCONFIG,"/sbin/ifconfig $interface |")
or (carp("Couldn't run 'ifconfig $interface'"), return undef);
while(<IFCONFIG>) {
if(/^.*:($ipregex).*:($ipregex).*:($ipregex)\s*$/o) {
($ip, $broadcast, $net) = ($1,$2,$3);
The output of the command "ifconfig" is:
eth0 Link encap:Ethernet Endereço de HW 20:CF:30:60:24:A1
inet end.: 192.168.20.254 Bcast:192.168.20.255 Masc:255.255.255.0
UP BROADCASTMULTICAST MTU:1500 Métrica:1
Then, just I added one space in the line of the script:
if(/^.*: ($ipregex).*:($ipregex).*:($ipregex)\s*$/o)
^
SPACE
And the installation proceeded normally.
I hope this may help you,
Angelo C. R.
