After setting up the vsftp to use PAM as auth.
Somehow having the following error appeared in
tail -f /var/log/secure |
Sep 21 09:47:45 g-server vsftpd: PAM [error: /lib/security/pam_userdb.so: wrong ELF class: ELFCLASS32] |
and resulting user can’t login to ftp service at all.
Apparently is because the system is 64-bit..
so the library is sitting somewhere else… correction is as below
session optional pam_keyinit.so force revoke
# 32-bit
#auth required /lib/security/pam_userdb.so db=/etc/vsftpd/vsftpd_users
#account required /lib/security/pam_userdb.so db=/etc/vsftpd/vsftpd_users
# 64-bit
auth required /lib64/security/pam_userdb.so db=/etc/vsftpd/vsftpd_users
account required /lib64/security/pam_userdb.so db=/etc/vsftpd/vsftpd_users

it much easier to setup because it come bundled with redhat / centos .
Note: Installation of NX Server for Linux requires the download and installation of three packages: client, node and server. The client is needed because it ships libraries used by the node. The node is needed because it ships tools needed by the server. Furthermore, the SSH server daemon (SSHD) needs to be up and running on each of the NX Node machines since NX relies on the mechanism provided by the SSH subsystem for handling user authentication.
