[LTP] [Query] Regarding network testcases

[Manjeet P. <man...@sa...>]

Hi,

I am facing issues while running some network testcases : e.g. if4-addr-change
This testcase belongs to latest (ltp-full-20150903.tar.bz2)
when I run this  if4-addr-change, I exported two new env variables a) IPV4_NETWORK = "107.109.223" and IPV6_NETWORK = "fd00::1:1:1:1", b) LHOST_IFACES = eth0 and RHOST_IFACES = eth0, which is not exported in "test_net.sh" .
bacause "if4-addr-change " testcase invokes "est_net.sh".

testcase output:
<<<<<<<<<<<<<<<<<<<test_start>>>>>>>>>>>>>>>>>>>
tag(Testcase Name)=if4-addr-change stime=15540
cmdline="if4-addr-change"

<<<<<<<<<<<<<<<<<<<test_end>>>>>>>>>>>>>>>>>>>>>

Please check the IP addresses taken by the program, they are in wrong format. 
Is there anything that I am missing to run this testcase ? . Also I tried to do manually fix to get IP addresses in correct way but that should not be done, it need many changes to be done in "test_net.sh".
This test scripts is invoked by  other testcases like  "network_stress.broken_ip". So all these testcases are failing.
Please suggest more detail regarding "test_net.sh". 

Thanks

Defining IPv6 network as IPV6_NETWORK = "fd00::1:1:1:1" is not quite 
correct. Here you have specified the IPv6 address, not network.

There are other variables that should be defined as well: 
LHOST_IPV4_HOST, RHOST_IPV4_HOST, LHOST_IPV6_HOST, RHOST_IPV6_HOST, i.e. 
host specific parts.

In your case IPv6 network is "fd00::/64", and I would set vars as follows:
IPV6_NETWORK = "fd00"
LHOST_IPV6_HOST=":1:1:1:1"

After that you will get fd00::1:1:1:1/64 address in the tests 
(${IPV6_NETWORK}:${LHOST_IPV6_HOST}).

Best regards,
Alexey
