RE: [SQU] stopping RealPlayer/RealAudio/RealVideo

i'm doing what you want this way:

create a file to store the file extensions which you want to restrict:

        #/squid/etc/deniedtypes
        # denied file extensions file:
        \.afx$
        \.asf$
        \.asx$
        \.au$
        \.avi$
        \.divx$
        \.m3u$
        \.mov$
        \.mp2$
        \.mp3$
        \.mpeg$
        \.mpg$
        \.qt$
        \.ra$
        \.ram$
        \.rm$
        \.viv$
        \.vivo$
        \.vob$
        \.vqf$
        \.wav$
        \.wma$
        \.wmv$
        \.vbs$
        \.shs$
        \.pif$

then add an acl that defines where your file is denied filetypes

        acl deniedtypes url_regex "/squid/etc/deniedtypes"

and then restrict http access for denied filetypes

        http_access deny deniedtypes

if you want you can give a special errormessage to your users by adding this
rule:

        deny_info ERR_DENIED_FILE_TYPE deniedtypes

this allows you to restrict multimedia video and audio filetypes and some
malicious scripts and such...

hope this helps

Subject: [SQU] stopping RealPlayer/RealAudio/RealVideo

hello,

I would like to block RealPlayer/RealAudio/RealVideo feeds into our
company. Although I can lock down the firewall RealPlayer 8 has an HTTP
access option that uses Port 80, which I cannot block or all of the HTTP
traffic will stop.

I do not want to use any sort of authentication but thought there might be
another way.

Any help would be appreciated.

Also, recently somone asked about stopping mp3 downloads but I cannot
seem to find the postings. I would like to stop avi's, mpg's etc. so would
like to see the ACL lists for mp3 again. Any help there would also be
appreciated.

thanks,

adrian
