It requires kernel with network namespaces support (CONFIG_NET_NS) + veth support (CONFIG_VETH), some tests require additional support. * using SSH (via TST_USE_SSH and RHOST variables): need to setup SSH access with keys or define password in PASSWD variable * using RSH (via RHOST variable) There is a helper script testscripts/network.sh (installed into /opt/ltp/testscripts/network.sh), which you can use instead of /opt/ltp/runltp. I removed RHOST to have the same default behavior for both runltp and network.sh. So, running "runltp -N" now performs testing via network namespaces. LTP/net doc (somehow obsolete, we need to update it): https://github.com/linux-test-project/ltp/tree/master/testcases/network https://github.com/linux-test-project/ltp/blob/master/INSTALL#L190 Some tests aren't ported to use tst_net.sh (route and multicast stress tests, RPC and TCP tests, ...) and still use rsh via LTP_RSH variable. These tests needs to be rewritten: https://github.com/linux-test-project/ltp/issues/128 https://github.com/linux-test-project/ltp/issues/310 Kind regards, Petr PS: CC LTP mailing list in case somebody is interested. > Hi Petr, > I'm new to LTP and trying to get LTP running in our environment. One particular area I'm having problem with is running network tests. I looked at the commit history of the LTP test and saw that you recently made some changes on how to run network tests. I wonder if you can help me on this. > Do you need a remote host to run the network tests? > If so, how do you specify the remote host? When I did "runltp -N", it didn't ask for any information on a remote host. Are there any setup I have to perform before issuing "runltp -N". > Regards, > Yulu Diao > commit 22a0cb31a5cb66bdeabbeb5d42299ecb4898fc2e > Author: Petr Vorel > Date: Mon Sep 3 12:41:34 2018 +0200 > runltp: Remove RHOST setup > as RSH is deprecated.
