[Proftpd-user] mod_sftp/symlink/solaris 10

[Frank L. <gfr...@gm...>]

Hi,

I am testing symbolic link with proftpd/mod_sftp on Solaris 10 x86.
It is chrooted in user home (~) directory.
/home/testuser/dir2
/home/testuser/dir/dir3 --> symbolic link to ../dir2

I am using sftp client that comes with Sun Solaris 10 ssh:
ssh -V
Sun_SSH_1.1.3, SSH protocols 1.5/2.0, OpenSSL 0x0090704f

When I sftp into "testuser", and go to /dir/dir3, "ls" doesn't show
anything. If I do "ls .", it will list all the files. If I go the
actual directory /dir2, "ls" can list all files fine.

If I install latest openssh on the solaris box and use the "sftp"
client from there, "ls" works fine. I also tried "lftp" and "ls" also
shows the files. It seems only Solaris sftp works differently.

I tried both proftpd 1.3.3 and 1.3.4 latest version, same problem.

Is there a compatible option I can set in proftpd to make it work with
Solaris sftp client?
