Hi All,

 

This is my first time visiting the vserver site. Upon reading the FAQ,
I came across this question:

 

http://linux-vserver.org/Frequently_Asked_Questions#Trying_to_connect_to
_a_vserver_from_the_host_or_another_vserver_on_the_same_host_fails

 

Below is the copy of the question and answer:

Trying to connect to a vserver from the host or another vserver on the
same host fails

strace shows

 
sin_addr=inet_addr("xx.xx.xx.xx")}, yy) = -1 EINVAL (Invalid argument)

A: The host/guest cannot communicate with another guest on same host.

* check all netmasks on all interfaces (do they overlap) ?

* check policy routing (disable it temporary) ?

* check that lo is up (Networking within a host/guest always
uses lo interface)

 

The answer has this line:

 

The host/guest cannot communicate with another guest on same host

 

Is this answer just a rephrasing of the question? Or is this a true
vserver's limitation?

 

Thank you!

 

Sincerely,

Woei Ng
