LNST on RHEL5

[Jan Tluka]

For everyone who still runs LNST on RHEL5.

Besides the python-ctypes requirement I've hit another issue:

<cut>
27/06 12:18:50|       (127.0.0.1)   NetTestSlave:0095| ERROR: 
    Traceback (most recent call last):
      File "/root/lnst/NetTest/NetTestSlave.py", line 91, in run_command
        return NetTestCommand(command).run()
      File "/root/lnst/NetTest/NetTestCommand.py", line 224, in __init__
        self._command_class = get_command_class(command)
      File "/root/lnst/NetTest/NetTestCommand.py", line 209, in
get_command_class
        return NetTestCommandTest(command)
      File "/root/lnst/NetTest/NetTestCommand.py", line 65, in
NetTestCommandTest

        except OSError as e:
                        ^
    SyntaxError: invalid syntax
</cut>

The reason is that RHEL5 comes with python version 2.4 and 'as' keyword
is not known to python2.4.

I was able to workaround it with following steps:

1. install python2.6 from epel [1]
2. run nettestslave with following command line:
# PYTHON_PATH=/usr/lib64/python2.6 /usr/bin/python26 ./nettestslave.py -d

Or another way is to modify TestIperf code to use:
        except OSError, e:

Oh, I didn't realize that. I'm using the 'as' keyword as well somewhere.
How are we going to deal with this? Should I change it to the way that's
compatible with 2.4?

IMO, I would not stick to the old syntax. RHEL5 is quite old and a
workaround exists. 

@Jirka, any thoughts on this?

Yes, please send patch changing this to old syntax. Once RHEL5 is gone
(in the future) we can change couple of things back again.

Thanks

Ok, I'll try to get all the occurrences of this in one patch.
