Hi all,
We have had complaints from customers who aren't able to download our products' installers on one of the sites we have in our server running Plesk 8.1.1. We've been able to reproduce the issue from here, inside our office network that is behind a SonicWall firewall with built-in antivirus, intrusion prevention, and spyware protection.
What happens is large EXE downloads would start, and then fail after a few kilobytes have been downloaded. IE says that the connection was reset, and FireFox would say that the source could not be read. It is the firewall terminating the connection. Something about the download makes it think that it's malware. When the protection is turned off in the firewall, downloads finish without problems.
What makes us think that this is an issue specific to our use of Plesk is that we have another Linux server without Plesk, and when we download the EXE from there, it goes fine. It is also not because of the way our Plesk server is set up in our collocation center, because I put the EXE in another machine there (it's a Windows Server), and the EXE also downloaded without problems from there.
Has anybody out there encountered such a problem? I've tried examining the packets sent to and from the server with Plesk and comparing them to the packets captured when making a connection to another Linux server without Plesk, but I haven't had any luck.
Any help would be appreciated.
