NetShield AutoUpdate through MS Proxy?

By eric.stroo ·
I've been trying to get NetShield's Automatic DAT Update feature to work for some time now, but unfortunately without any success until now. The address used to obtain the update is: ftp.nai.com/pub/antivirus/datfiles/4.x and the connection to the Internet is made via Microsoft Proxy Server on port 80.

In my opinion it is very likely a problem with MS Proxy Server 2.0, since the file delta.ini is created in a temporary directory, but it remains empty (0 kb). Somehow the content of the file is not getting through. When I try to download it by manually logging in to ftp.nai.com, there isn't any problem at all.

The NetShield Activity Log provides the following information:
22-3-01 12:10 Update QUATRO\Administrator Locating installation and temp directories.
22-3-01 12:10 Update QUATRO\Administrator Initializing the Internet subsystem.
22-3-01 12:10 Update QUATRO\Administrator Connecting to the remote host.
22-3-01 12:10 Update QUATRO\Administrator Incremental Process Started
22-3-01 12:10 Update QUATRO\Administrator Incremental Process loading required Libraries
22-3-01 12:10 Update QUATRO\Administrator Retrieving the update file 'DELTA.INI'.
22-3-01 12:10 Update QUATRO\Administrator Retrieving the update file 'delta.ini'.
22-3-01 12:15 Update QUATRO\Administrator Incremental Process finished (4)
22-3-01 12:20 Update QUATRO\Administrator An unknown error occurred while reading from the remotesystem and the connection was dropped.

The connection to the Internet is made via Microsoft Proxy Server on port
80.

I hope someone can help me out...

NetShield AutoUpdate through MS Proxy?

It sounds like you need to use FTP in 'passive' mode, but I don't see anywhere in the Automatic DAT upgrade properties to tell it to use FTP in passive mode. There is a place to put proxy settings (address and port), and it sounds like you've done that?

When you say it works fine if you log in manually and do it, I don't know if you mean you log in using FTP or through a browser. If you mean you access it manually through a browser, then that supports my suggestion below.

Do you have the MS Proxy client installed on this machine? You need it if you're doing non-browser related services through the proxy, like FTP or telnet, etc., and I'm sure that the DAT update client is using pure FTP.

Otherwise, you need to check the Proxy configuration and make sure it is allowing FTP service through ports 21 and 20.

Installing the Proxy Client seems to be the answer.

If you are using Netshield 4.0.3x this error is not surprising. I had a similar problem at my site . The simplest remedy is to ensure IE 4 minimum is loaded and Netshield 4.5 SP1. NA have also changed the update address to ftp.nai.com/virusdefs/4.x.
