************************************************* This message has been scanned by IMSS NIT-Silchar Hello Amos Jeffries, It does not work doing that way. It shows up the same errors as b before. A few lines from my squi.conf are as shown below: #acl stud_hostel time MTWHFA 18:00-6:00 #acl stud_hostel time S 00:00-24:00 acl college_time time M T W H F A 7:30-18:00 acl cg_lab_time time T H 14:00-17:00 acl cg_lab_net src 192.168.2.50-192.168.2.68/32 The first line is as you had said, that there should not be any white space between the days, so i did it like that, but on restarting the squid, it showed up the same errors again. The below lines are working fine with white spaces between between the days. Any pointers ??
