Well I tried to download freebsd iso and i issued the command:
wget
http://mymirror.asiaosc.org/freebsd/...i386-disc1.iso --proxy-user=[username] --proxy-passwd=[password] -vO - |split -b 90m - bsd
But it showed the following error message:
--09:41:04--
http://mymirror.asiaosc.org/freebsd/...i386-disc1.iso
=> `-'

Theproxy blocks http and ftp both. However it only checks the size of the file being downloaded at a time not the whole file size, that's where the trick can be played. Please suggest something. Obviously our sysadmin owns the proxy.
