Hello all, I've been befuddled with a SNMP problem. I've got a squid box running as a transparent cache (using wccp) which is working fine. I've tried to get SNMP going so that I can use MRTG to generate usage graphs. Where things stand now is SNMP queries work fine from the localhost which squid is running on... ie:
snmpwalk 192.168.255.120:3401 -c public .1.3.6.1.4.1.3495.1.1 returns: enterprises.3495.1.1.1.0 = 2636 enterprises.3495.1.1.2.0 = 123976 enterprises.3495.1.1.3.0 = Timeticks: (261736) 0:43:37.36 however that same statement from another box on the same network yeilds a time out and I get "Failed SNMP agent query from : 192.168.252.82." on the squid box. I've been unable to find any similar situations on the web and the archives of this mailing list. So I'm wondering if anyone else has seen this and or has any thoughts on how to diagnose this. Here are the pertinent sections of my squid.conf: acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 563 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 563 # https, snews acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT acl snmppub snmp_community public acl logger src 192.168.252.82/255.255.255.255 http_access allow manager localhost http_access deny manager # Deny requests to unknown ports http_access deny !Safe_ports # Deny CONNECT to other than SSL ports http_access deny CONNECT !SSL_ports acl our_networks src 192.168.252.0/22 http_access allow our_networks http_reply_access allow all snmp_access allow snmppub logger snmp_access deny all Any help at all would be greatly appreciated!
