    Hi,

    Has anyone out there had experience with IP throttling? Is there a firewall package available which will 'give priority' to certain ports/users at different times of day. for example im sharing out dsl but would like to give priotity to http browsing and pop3 during the day and then let kazaa / ftp take full command of the bandwidth at night.

    Im a novice linux user, at the moment i have mandrake ver9 loaded on an athlon pc running squid / dns / wins and firewall.


    And then to put the icing on the cake, is there a prog out there which could pull mrtg stlye stats on an 'per ip' basis? or even better mac?


    any such thing as a windows solution to above ;)

    Many thanks in advance


    Adrian

    This may not be exactly what your looking for, but it's a handy tool so i thought i'd post it anyway :)

    Trickle

    It's a tool that wraps around another application (eg ftp or whatever) and limits that application's bandwidth usage to a specified limit.

    eg

    trickle -u 10 -d 20 ftp

    would run an ftp session, limiting its upload capacity to 10 KB/s, and download capacity at 20 KB/s.

    So you could easily create wrapper scripts for the apps you want to be able to throttle and then use cron to change which script gets run by default at different times. Of course there are more sophisticated methods than this, proper bandwidth management software is out there.

    Kernel 2.4 has a fair amount of QOS stuff in. Search around on the linux documentation project for rusty russel's guides. He has some stuff on qos in it.

    could you not use something involving crontab and iptables possibly, maybe even blocking traffic???

    that trickle thing is cool davej!!

    Excellent post...I'm sick of waiting till 5.30 when everyone leaves the office before I start my ftp downloads cos the max out our line and nobody can get email, browse etc. etc.

    now I can leave the other losers in work 1 or 2 measly k for their "web browsing" while I go full steam ahead!!!

    muhahahahahaha...

    thanks alot for the tip,
