[squid-users] Squid v4.1: commBind Cannot bind [::1] on SNMP with no ipv6

[David Touzeau]

Hi

 

Hi,

 

Ipv6 is not enabled on this Debian 9 system.

 

sysctl -a |grep ipv6|grep disable

sysctl: reading key "net.ipv6.conf.all.stable_secret"

sysctl: reading key "net.ipv6.conf.default.stable_secret"

sysctl: reading key "net.ipv6.conf.eth0.stable_secret"

net.ipv6.conf.all.disable_ipv6 = 1

net.ipv6.conf.default.disable_ipv6 = 1

sysctl: reading key "net.ipv6.conf.eth1.stable_secret"

sysctl: reading key "net.ipv6.conf.lo.stable_secret"

net.ipv6.conf.eth0.disable_ipv6 = 1

net.ipv6.conf.eth1.disable_ipv6 = 1

net.ipv6.conf.lo.disable_ipv6 = 1

 

Squid try to open a socket on ipv6 loopback.

How to avoid this error ?

 

Config :

snmp_port 3401

snmp_incoming_address 0.0.0.0

#snmp_outgoing_address 255.255.255.255

acl snmppublic snmp_community public

acl snmpConsole src 127.0.0.1

snmp_access allow snmpConsole

snmp_access allow snmppublic snmpConsole

snmp_access allow snmppublic localhost

snmp_access allow snmppublic MgRClient

snmp_access deny all
