Destination Host Unreachable

[TomHowarth]

Senario:

Workstation 7 running under Centos5 ESX 3.5 guest running on Host only network will not see network, it can ping its self on is own IP and localhost ip, Windows Guests can ping themselves and everything else except the ESX 3.5 guest. vSphere 4 guests also function correctly.

I have run the command chmod a+rw /dev/vmnet# to allow a standard user to move the vmnics into promiscious mode.

Hi Tom

does it work if you run Workstation as root ?

do you run that command after every boot ? - I am not sure if it will stick ?

Good point not checked, I tend not to run things as root if I can help it :smileygrin:

I vaguely remember that KSC or Jim Mattson mentioned something like that .. thanks UDEV the flags on the dev-nodes don't stick ...

Tom

did you check if the permissions you set on the /dev files survive a reboot ?

Hi Tom,

Was wondering if you managed to resolve this issue? I am getting exactly the same symptoms running on ubuntu 10.10/Workstation 7.1.4. I have done the chgrp a+rw on the /dev/vmnet<nn> devices but to no avail.

I have 5 vm's running (within workstation), the windows server can ping the host and other non-esx hosts as can they by return but the ESX hosts just seem to sit there. I have checked the nics and all are up and running, checked the vswitches, they are configured correctly and as I am running evaluation license, I checked the license for expiry to be told that I have 1406 hours remaining.

I get the "Destination Host Unreachable" message whenever I try to ping anywhere. I thought it might be the firewall so did an esxcfg-firewall --allowIncoming --allowOutgoing and this had no effect.

I've tried using bridged connections as well and tried NAT all to no avail. The strange thing is that I can see some arp packets going down the line when I spy on the interface from my Linux host using wireshark. If I try to ping, it will ask who has that IP.

Sorry for jumping in on the thread.

Thanks

David
