Hi folks, I've got an OpenBSD gateway (including NAT) redirecting HTTP traffic to a dedicated internal Linux host running Squid 3.1.9. Problem: I see tons of messages in cache.log : 2011/01/04 11:03:38| IpIntercept.cc(137) NetfilterInterception: NF getsockopt(SO_ORIGINAL_DST) failed on FD 12: (92) Protocol not available 2011/01/04 11:03:38| IpIntercept.cc(137) NetfilterInterception: NF getsockopt(SO_ORIGINAL_DST) failed on FD 21: (92) Protocol not available 2011/01/04 11:03:45| IpIntercept.cc(137) NetfilterInterception: NF getsockopt(SO_ORIGINAL_DST) failed on FD 10: (92) Protocol not available 2011/01/04 11:03:47| IpIntercept.cc(137) NetfilterInterception: NF getsockopt(SO_ORIGINAL_DST) failed on FD 28: (92) Protocol not available : Web access doesn't seem to be affected. How can I tell squid to shut up? Google recommended on the mailing list to use a dedicated intercept address, but this did not help. Here is the squid.conf file: http_access allow all http_port 3128 http_port 3129 intercept hierarchy_stoplist cgi-bin ? cache_dir aufs /var/spool/squid3 4096 16 256 access_log none coredump_dir /var/spool/squid3 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 icap_enable on icap_preview_enable on icap_preview_size 128 icap_send_client_ip on icap_service service_req reqmod_precache bypass=1 icap://127.0.0.1:1344/squidclamav icap_service service_resp respmod_precache bypass=0 icap://127.0.0.1:1344/squidclamav adaptation_access service_req allow all adaptation_access service_resp allow all squid -v: Squid Cache: Version 3.1.9 configure options: '--build=x86_64-linux-gnu' '--prefix=/usr' '--includedir=${prefix}/include' '--mandir=${prefix}/share/man' '--infodir=${prefix}/share/info' '--sysconfdir=/etc' '--localstatedir=/var' '--libexecdir=${prefix}/lib/squid3' '--disable-maintainer-mode' '--disable-dependency-tracking' '--disable-silent-rules' '--srcdir=.'
