select() has a maximum value for the FDs it can monitor, and since the libguestfs library can be used in other applications, this limit may be hit by users in case lots of FDs are opened. As solution, switch to poll(): it has a slightly better interface to check what changed and for which FD, and it does not have a limit in the value of...

Thanks Craig for your soon answer.. I've now the FDS up and running... I am now creating my users in FDS because I want to unify the authentication of my 3 centos servers. BUT, When I create my users in FDS I don't see any option of UID, GID, home directory, etc, so the FDS server return an error and my remote users can't authenticate.........

Using simple authentication I have been able to tie FDS to Samba 3.x.24. Knowing that the unix passwd and smb passwd are different, dare I ask how difficult it would be to have them sync? Most of my users are using netatalk w/ posix user info and MD5 password. I would like to swing this over to samba without the worries of two passwords per user. I have...

The previous code: fcntl (fd, F_SETFL, O_NONBLOCK) was technically incorrect, because it would have reset any other flags on the file descriptor.
