LTP Network Tests

Pre-requisites

Enable all the networking services on test machine(s): rshd, nfsd, fingerd.

Single Host Configuration

It is a default configuration ('RHOST' is not defined). LTP adds 'ltp_ns' network namespace and auto-configure 'veth' pair according to LTP network environment variables.

Two Host Configuration

This setup requires 'RHOST' environment variable to be set properly and configured SSH or RSH (default) access to a remote host.

The 'RHOST' variable name must be set to the hostname of the server (test management link) and PASSWD should be set to the root password of the remote server.

In order to have RSH access:

• Edit the "/root/.rhosts" file. Please note that the file may not exist, so you must create one if it does not. You must add the fully qualified hostname of the machine you are testing on to this file. By adding the test machine's hostname to this file, you will be allowing the machine to rsh to itself, as root, without the requirement of a password.

echo $client_hostname >> /root/.rhosts

You may need to re-label '.rhost' file to make sure rlogind will have access to it:

/sbin/restorecon -v /root/.rhosts

• Add rlogin, rsh, rexec into /etc/securetty file:

for i in rlogin rsh rexec; do echo $i >> /etc/securetty; done

Server Services Configuration

Verify that the below daemon services are running. If not, please install and start them: rsh-server, telnet-server, finger-server, rdist, rsync, dhcp-server, http-server.

Note: If any of the above daemon is not running on server, the test related to that service running from client will fail.

FTP setup

• In “/etc/ftpusers” [or vi /etc/vsftpd.ftpusers], comment the line containing “root” string. This file lists all those users who are not given access to do ftp on the current system.

• If you don’t want to do the previous step, put following entry into /root/.netrc machine <remote_server_name> login root password <remote_root_password>. Otherwise, ftp,rlogin & telnet fails for ‘root’ user & hence needs to be executed using ‘test’ user to get successful results.

LTP setup

Install LTP testsuite. In case of two hosts configuration, make sure LTP is installed on both client and server machines.

Testcases and network tools must be in PATH, e.g.:

export PATH=/opt/ltp/testcases/bin:/usr/bin:$PATH

Default values for all LTP network variables are set in testcases/lib/tst_net.sh. If you need to override some parameters please export them before test run or specify them when running ltp-pan or testscripts/network.sh.

Running the tests

To run the test type the following:

TEST_VARS ./network.sh OPTIONS

Where

• TEST_VARS - non-default network parameters (see testcases/lib/tst_net.sh), they could be exported before test run;
• OPTIONS - test group(s), use '-h' to see available ones.

Analyzing the results

Generally this test must be run more than 24 hours. When you want to stop the test press CTRL+C to stop ./network.sh.

Search failed tests in LTP logfile using grep FAIL . For any failures, run the individual tests and then try to come to the conclusion.
