[Proftpd-user] help! about mod_cap/1.0: setreuid: Operation not permitte

[刘知言 <lz...@gm...>]

Hi, all:

I use 1.3.3a (and tried 1.3.3) on RHEL 5.3 x86_64 os, when I use sftp
client to connect proftd sftp server, I got this error:
=======================
FTP session opened.
Preparing to chroot to directory '/home/home_sftp/testuser'
USER testuser: Login successful
mod_cap/1.0: setreuid: Operation not permitte
SSH2 session closed.
=======================

and client sftp socket reset by peer.

the proftp config is:
=======================

=======================

How to slove this error? Is this a question about linux capabilities
upgrade in rhel 5.3. I can success connect proftpd in rhtl 5.0 & 5.1
env.

I need help, thanks very much!
