No checkboxes in Performance

[postman]

Hi,
I noticed a 'Performance' icon in my domains and like the idea of being able to limit some domains by the number of connections (to hopefully reduce DoS type attacks).
However, when I visit the Permformance tab I do not see any tickboxes or spaces to enter a number - all I have is the text 'unlimited'. e.g.
Bandwidth limiting
Maximum network use (KB/s) Unlimited
Connections limiting
Connections limited to Unlimited
I have checked the help pages and searched the web but have not found anything.
Is there something else I need to do to enable this ?
Thanks in advance,
postman

You must install mod_bw first and reboot

 

[postman]

Thanks for the pointer. I have now download the source and installed but I still do not have the checkboxes on the performance page. I have added the following to the vhost.conf in a domain ./conf directory to test it:
BandwidthModule On
ForceBandWidthModule On
Bandwidth all 10240
MinBandwidth all -1
But still no management from within Plesk. Am I missing something?

Incidentally I had this error after installing mod_bw
httpd: Syntax error on line 208 of /etc/httpd/conf/httpd.conf: Cannot load /usr/lib/httpd/modules/mod_bw.so into server: /usr/lib/httpd/modules/mod_bw.so: undefined symbol: apr_atomic_cas
which was solved by editing the mod_bw.c file before compiling and changing:
# if (APR_MAJOR_VERSION <1)
to
# if (APR_MAJOR_VERSION >=1)
then I did /usr/sbin/apxs -i -a -c mod_bw.c

Why don't you install mod_bw from plesk updater?

Exactly! You have it in yor Updates menu.
