[LTP] [PATCH 1/6] ftp/ftp01: Use tst_net.sh

[Petr Vorel]

Hi Akihiko,

I'm sorry I overlooked your message at v1
https://lore.kernel.org/ltp/9894db50-6319-a818-c995-3ba9ab102c4b@daynix.com/

I guess script expects $PASSWD to be set.
Also trying to follow the instruction, none of them (allowing root in
/etc/ftpusers or filling /root/.netrc with machine localhost) work for me:
https://github.com/linux-test-project/ltp/tree/master/testcases/network#ftp-and-telnet-setup

I suppose any ftpd implementation must be run on the remote server (localhost,
if tst_net.sh uses netns - the default or on remote host, if ssh is used).
Otherwise ftp command "user $RUSER $PASSWD" cannot work, right?

Although it should behave the same regardless netns or ssh is used,
how do you test v3, with ssh or with netns (the default)? Or both?

It'd be nice if there was connection detection in the setup and tst_brk TCONF if
login does not work. The best would be to have configuration in the setup() +
cleanup in the cleanup()).

There are tests, which do vsftpd configuration: ftp-download-stress.sh,
ftp-upload-stress.sh.

BTW in the past we seriously considered to delete these highlevel smoke tests.
LTP is concentrated to test kernel API and internals, thus we didn't see much
value with smoke tests like this (that's why they haven't been rewritten to use
new API), specially if they require complex setup and get false positives when
SUT not configured properly. That's why it'd be nice to at least TCONF (if not
doing whole setup).

Kind regards,
Petr
