Hi,
I have setup two ESX hosts and I am running two VMs in them. Now what happens is that if I run netserver in one particular VM and netperf in another particular VM, it says:
establish_control: are you sure there is a netserver listening on 10.15.213.99 at port 12865?
establish_control could not establish the control connection from 0.0.0.0 port 0 address family AF_UNSPEC to 10.15.213.99 port 12865 address family AF_UNSPEC
The commands used are:
netserver (one VM)
netperf -H 10.15.213.99 (another VM)
On the other hand if I run the netperf/netserver from opposite direction, it works perfectly.
More interestingly, if I create two VMs on that (culprit) ESX host then this works perfectly too. So I thought that mf ESX host has some firewall issues. So I do the following for ESX host:
chkconfig firewall off
esxcfg-firewall --allowIncoming --allowOutgoing
service iptables stop
and from VM I do the following:
chkconfig firewall off
service iptables stop
But of no avail. This is a peculiar problem and I believe this will entertain us all to find the proper solution.
Some help would be greatly appreciated here.
