Hi there, I recently installed the squid and I tried the minimal configuration in a virtual machine. The squid gives access to other machine, but it keeps failing with a error "(21) Is a directory" when I tried access the "www.google.com.br". I replaced the version 3.4.5 with the version 3.2 and 3.1 and all get the same error. The version 2.7 worked well. Can it be my configuration mistake or it is a bug? I used the squid.conf.default that came in the source. I managed to get the log of this error: 2014/05/13 19:14:00.603| comm.cc(1114) connect: to 173.194.42.183:80 2014/05/13 19:14:00.603| comm_connect_addr: connecting socket 12 to 173.194.42.183:80 (want family: 2) 2014/05/13 19:14:00.603| comm_connect_addr: sock=12, addrinfo( flags=4, family=2, socktype=1, protocol=6, &addr=0x112ff70, addrlen=16 ) 2014/05/13 19:14:00.603| connect FD 12: (-1) (21) Is a directory 2014/05/13 19:14:00.603| connecting to: 173.194.42.183:80 2014/05/13 19:14:00.603| comm.cc(1147) connect: FD 12: * - try again I compiled this version of the squid myself running: $ ./configure --enable-ssl --disable-ipv6 && make Another question, is the version 3.4.5 suitable for production use? Or it is recommend the use of version 2.7 yet? Thanks
