Unable to connect to the Plesk server via FTP: ftp: connect: Connection timed out

Symptoms

• Unable to connect to the server via FTP, the process fails with the error:
  

  CONFIG_TEXT: 227 Entering Passive Mode (203,0,13,2,119,129).
  ftp: connect: Connection timed out

  ---

  CONFIG_TEXT: Error: Connection timed out after 20 seconds of inactivity Error: Failed to retrieve directory listing

• The nmap utility shows that the passive port range (49152-65535) is in the closed state:

  # nmap -p49192,65535 203.0.13.2
  Host is up (0.25s latency).
  PORT STATE SERVICE
  
  49192/tcp closed unknown
  65535/tcp closed unknown

• In an attempt to manually calculate the result of the passive FTP port((119*256)+129=30593), the value is not within the range (49152-65535)

Cause

The wrong range for passive ports is set in /etc/proftpd.d/55-passive-ports.conf file.

Resolution

1. Log in to the server via SSH
2. Open the /etc/proftpd.d/55-passive-ports.conf file with text editor of your choice, vi for example
3. Change the line with the PassivePorts directive to the following:
   

   CONFIG_TEXT: PassivePorts 49152 65535

4. Restart xinetd service to apply the changes:
   

   # service xinetd restart
