Last year, after upgrading to Cpanel 11.24.4 from a fairly old version, I could no longer access FTP accounts that had been previously setup under a specific domain. Before the upgrade this user had multiple FTP accounts that worked perfectly. After the upgrade we can recreate and delete these accounts all day long and nothing works. I have also restricted FTP to SFTP which works perfectly on the default domain FTP user. All other accounts don't work and return the following error in /var/log/secure;
Apr 20 17:50:30 serv1 sshd[28186]: Invalid user
client02@example.com from ::ffff:71.117.232.229
Apr 20 17:50:30 serv1 sshd[28187]: input_userauth_request: invalid user
client02@example.com
Apr 20 17:50:33 serv1 sshd[28186]: Failed password for invalid user
client02@example.com from ::ffff:192.168.0.1 port 2430 ssh2
Apr 20 17:50:33 serv1 sshd[28187]: Received disconnect from ::ffff:192.168.0.1: 12: User authentication failed.
You'll notice the mention of port 2430 in the errors above. However, that is not the port used for SFTP on this server. Is that the problem? If yes, why would that port be different from the one I have manually set in CuteFTP?
These FTP users have been setup using CPanel > FTP Accounts. I have also tried changing FTP servers in WHM, it is back to Pure-FTPD right now.
Any help or direction would be appreciated.
Thanks.
