i am using squid with delay pool
so i have to use ip address ranges in
acl pool1 scr 192.168.0.1-192.168.0.25/255.255.255.0
acl pool2 scr 192.168.0.26-192.168.0.50/255.255.255.0
acl pool3 scr 192.168.0.51-192.168.0.75/255.255.255.0
acl pool4 scr 192.168.0.76-192.168.0.100/255.255.255.0

but when i stop squid it gives warning message
as

[root@postfix squid]# service squid stop

................ OK ]



pls suggest me if i am using wrong acl atatement , or error in subnet mask

Stupid me for suggesting this, might be more complicated:
_First_ check the client_netmask entry in squid.conf to be the same as your declared: 255.255.255.0
Then... I don't know yet.

The subnet mask is same as i declared

now i am using acl without subnet masks
as
acl student src 192.168.0.1-192.168.0.25

etc...

working ok with this
