A computing update

by on Jul.02, 2009, under Microsoft

Well I know I haven’t written much about the type of computing I have been doing recently,  well that is about to change.

As I work on a support desk having to do technical support and new service provisioning. I spend a lot of time working on helping our users troubleshoot issues they may have.

Recently I have been building a virtual exchange 2007 server server a virtual machine with Icewarps merak mail server. once I have the whole thing configured and built I shall do a write up on provisioning the setup.

Today I have been setting up a MS FTP 7.5 server which allows connections of SSL. The main instructions for the service were obtained from iis.net but I then encountered some problems being able to connect to the service from the Internet.

As my office has a direct VPN connect to the servers it was difficult to test the connection. what we found for the Internet was the passive connection could not be established after the initial FTP connection.

We found after reading Configuring FTP Firewall settings also from iis.net and applying the firewall rule

netsh advfirewall firewall add rule name="FTP for IIS7" service=ftpsvc action=allow protocol=TCP dir=in

and adding the passive connection ports to the Windows Firewall the issue seems to be resolved.

One thing I must add is that if you are using the ftp server for yourself and just want to encrypt the traffic a self signed certificate is OK but if you are opening up the server the clients, suppliers, partners or any one else I would suggest a certificate from a recognised certificate body like Thawte or Verisign and other certificate authorities are also available.
