container_ftp.pl has several problems:
* ftp users can't cd to a temporary dir in /tmp
* ftp->cwd($dir) will always fail
* if we do 'chdir $dir', 'rmdir("$dir")' will fail
* 'ftp->put' should be 'ftp->get'

hi, Simon
I tested container_ftp.pl as follow:
********************************************************
#./container_ftp.pl knownhost_with_vsftpd
********************************************************
and failed at "$ftp->cwd" either with this fix or without it.
So,did i get the wrong way to test this script ,or,something wrong
still exists.
Could you print the value of $dir before "$ftp->cwd"? And try ftp
login as anonymous user, and see if you can cd to the value.
Thanks for your quick reply and sorry for my careless.
I try operations as you suggested,and find the problem that dir created
for test is not available
for any user expect root.
So, now i test and confirm this fix works fine.
Thanks
DAN LI
Thanks
Simon
