How to change my FTP Password

When I login into FTP to add files on my server It don't want to login because I forget my pass anyway to change it?

./ftp.sh: line 59: syntax error near unexpected token then' ./ftp.sh: line 59: then'

I'm running a process on port 2165. When the installer checks to see if another FTP server is running it seems to check all ports beginning with 21* rather than specifically port 21.

Output below:

FTP ERROR: There is already a running FTP server on port 21:
tcp 0 0 0.0.0.0:2165 0.0.0.0:* LISTEN
tcp6 0 0 :::2165 :::* LISTEN
You must manually stop the other FTP server first. SKIPPING FTP server installation.

When trying to stop a running server by pressing restart or stop. It only occurs on running server !

Latest update.sh script changes all /usr/local/gpx/users subfolder's owner to root:gpx, and changes all permissions to only allow root to see and change files inside.
This causes gameservers to not start, and many other problems.

When you have more than 10 users+ It will give Loading not Online 0/75 or Offline 0/75

A sane system administrator would use SSH keys for their servers instead of plain password.
One might argue that strong passwords can prevent a server from being compromised but why not secure the server even further through only allow SSH keys logins?

I would like to suggest GPX to add support for SSH keys for the remote game server so that the login from the master doesn't to the slave/remote is done securely through SSH keys.

Set permissions of '/xx.xxx.xx:xxxx/resources/default/server/xxxxx.xx' to '775'
Command: SITE CHMOD 775 xxxxx.xx
Response: 550 Could not change perms on xxxxx.xx

This way user that connects via FTP can't do anything without admin assistance. Any way to fix this? Using Ubnutu 14 x32
