Hello,
Having recently upgraded from squid 3.4.8 to squid 4.4, I stumbled
into an issue that I tried to simplify the most I could through the
attached configuration files and the explanation below.
I would like to use an external acl to set bandwidth limitations
for my different users. So in squid 3.4.8, I would do something like
(that's just a very simple example) :
delay_pools 1
delay_class 1 3
external_acl_type ip_user_helper %SRC
/usr/lib/squid3/ext_file_userip_acl -f /etc/squid/ips.conf
acl ip_list external ip_user_helper test
delay_access 1 allow ip_list
delay_access 1 deny all
delay_parameters 1 80000/80000 80000/80000 80000/80000
with /tmp/ips.conf containing something like :
10.1.0.55 ALL
If the ip I want to limit the bandwidth of is 10.1.0.55. In squid
4.4 however, I can't get it to work properly : the user can access her
page but she is not limited as expected and I get the following message
multiple times in my cache.log file :
WARNING: ip_list ACL is used in context without an ALE
state. Assuming mismatch.
I believe it is related but I am not sure (or maybe I just did
something wrong). You can find a minimal configuration file attached to
reproduce.
Thanks in advance for your help,
Regards,
Luca
