# 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.
|
|
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
echo $client_hostname >> /root/.rhosts
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
You may need to re-label '.rhost' file to make sure rlogind will have access to it:
|
|
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
/sbin/restorecon -v /root/.rhosts
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
* Add rlogin, rsh, rexec into /etc/securetty file:
|
|
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
for i in rlogin rsh rexec; do echo $i >> /etc/securetty; done
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## Server Services Configuration
|
|
|
|
|
|
Verify that the below daemon services are running. If not, please install
|
|
|
|
|
|
and start them:
|
|
|
|
|
|
rsh-server, telnet-server, finger-server, rdist, rsync, dhcp-server, http-server.
|
|
|
|
|
|
|
|
|
|
|
|
Note: If any of the above daemon is not running on server, the test related to
|
|
|
|
|
|
that service running from client will fail.
|
|
|
|
|
|
|
|
|
|
|
|
### FTP setup
|
|
|
|
|
|
* In “/etc/ftpusers” [or vi /etc/vsftpd.ftpusers], comment the line containing
|
|
|
|
|
|
“root” string. This file lists all those users who are not given access to do ftp
|
|
|
|
|
|
on the current system.
|
|
|
|
|
|
|
|
|
|
|
|
* If you don’t want to do the previous step, put following entry into /root/.netrc
|
|
|
|
|
|
machine <remote_server_name> login root password <remote_root_password>.
|
|
|
|
|
|
Otherwise, ftp,rlogin & telnet fails for ‘root’ user & hence needs to be
|
|
|
|
|
|
executed using ‘test’ user to get successful results.
|
|
|
|
|
|
|
|
|
|
|
|
## LTP setup
|
|
|
|
|
|
Install LTP testsuite. In case of two hosts configuration, make sure LTP is installed
|
|
|
|
|
|
on both client and server machines.
|
|
|
|
|
|
|
|
|
|
|
|
Testcases and network tools must be in PATH, e.g.:
|
|
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
export PATH=/opt/ltp/testcases/bin:/usr/bin:$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:
|
|
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
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 <logfile>. For any failures,
|
|
|
|
|
|
run the individual tests and then try to come to the conclusion.
