Subject Re: Flume ERROR
Date Fri, 07 Aug 2015 14:20:35 GMT
Thanks AnandKumar.

Flushing the firewall rules is admin related work right?

Redhat 4.7 is our OS.

Linux version 2.6.32-504.3.3.el6.x86_64 (
mockbuild@x86-028.build.eng.bos.redhat.com) (gcc version 4.4.7 20120313
(Red Hat 4.4.7-9) (GCC) ) #1 SMP Fri Dec 12 16:05:43 EST 2014

Regards,
Nik.
