Hi again... I don't know what happened (if I changed something or if I wrongfuly thought it was fixed) but the siblings are not talking anymore... at all. :( No error message, no denied... So let's start from the begining... configure --prefix=$PREFIX \ --enable-time-hack \ --enable-underscores \ --with-pthreads \ --enable-storeio="aufs,coss,diskd,null,ufs" \ --enable-removal-policies="heap,lru" \ --enable-delay-pools \ --enable-useragent-log \ --enable-referer-log \ --enable-snmp \ --enable-cachemgr-hostname=localhost \ --enable-arp-acl \ --enable-ssl \ --enable-cache-digests \ --enable-epoll \ --enable-linux-netfilter \ --disable-ident-lookups \ --disable-internal-dns \ --with-large-files \ --with-maxfd=65535 Do I miss something? Do I need any of these too for siblings to talk? --enable-icmp, --enable-htcp, --enable-forw-via-db...
