On the menu bar, go to Tools > Global Options.
Click Connection.
Global Max number of connections
Choose the number of simultaneous connections you will allow from CuteFTP Pro and the Transfer Engine.
On a Windows 95/98/ME computer you can choose up to 40 connections.
On a Windows NT/2k/XP computer you can choose up to 200 connections, but CuteFTP Pro will warn you that more than 20 connections may compromise system performance.
Connections include transfers, browser sessions, and every single thread in a Multi-Part transfer.
Max number of connections per site
Choose the number of simultaneous connections you will allow to any one remote site. Choose up to 200. Connections include transfers, browser sessions, and even a single thread in a Multi-Part transfer.
Connection retry attempts
Choose the number of times CuteFTP Pro can try to connect with a site before giving up. You can set CuteFTP Pro to try connecting up to 1,000 times.
Delay between retries in seconds
Choose how long CuteFTP Pro will wait before attempting a new connection after a failed connection. Choose up to 1,000 seconds (about 17 minutes).
Choose Auto and CuteFTP Pro will try to make connections in PASV mode. If the PASV connection fails, CuteFTP Pro will try the connection in PORT mode automatically.
PASV helps avoid conflicts with security systems. PASV support is necessary for some firewalls and routers, because with PASV, the client opens the connection to an IP Address and port that the server supplies.
Choose PORT when connections or transfer attempts fail in PASV mode, or when you receive data socket errors. When an FTP client connects using PORT, the server opens a connection to an IP Address and port that the client supplies.
Note
If you connect in PORT mode your session becomes vulnerable to "Port theft", where a third party can interfere with transfers.
E-mail address for anonymous logins
Enter the address you want to send to servers that require an e-mail address for anonymous logins. By default CuteFTP pro sends a simulated e-mail address.
Retry failed logins without issuing a socket disconnect
Select this check box to have CuteFTP Pro attempt repeated logins without reconnecting to the server.
Clear this check box to have CuteFTP Pro disconnect and reconnect with every new attempt to login after a login attempt has failed.
Send QUIT command before disconnecting
Select this check box to always send the QUIT command from CuteFTP Pro no matter how you choose to disconnect.
Clear this check box to disconnect without sending the QUIT command.
