AIX 5.3 FTP Folder Restriction
Hi All,

How can I restrict the folder on an FTP USER on AIX 5.3? I don't want the ID to change folder other than his own home folder.

Thanks for any comment you may add.

Set up properly, a sym-link to root in the home dir will not allow escape, as is common!

i found AIX 5.2/5.3 solution,

just do this

Code:
# cat /etc/ftpaccess.ctl
useronly: ftp1
#ls -la /etc/ftpaccess.ctl
-rw-------    1 root     system           18 Oct 20 13:49 /etc/ftpaccess.ctl

the only problem is, it doesn't show the sub folder. user need to have knowledge of the hidden sub folder, ugh...

Yes, it has that option. What subfolder is this? Is it .hidden? A sym-link?

Help - ftpaccess.ctl

PS: Test to see if a sym link lets the ftp user out!

ln -s / ~/root

it's just a regular sub folder and it doesn't show, i talk to support and he talk to an L3 developer who owns the code, it's really like that...

Maybe AIX meant just the $HOME directory, not any subfolders! That's one way to defeat sym links out to other dirs: no dirs at all! Do any dirs show? Is this dir in any way different: mode, mount point, group, owner?

For a ftp only user there is no Shell and the user is locked into one directory.
