Hi This bug has been forwarded from http://bugs.debian.org/685638 Package: libio-socket-inet6-perl Version: 2.65-1.1 Severity: normal This is similar to #185244[1] but for libio-socket-inet6-perl. The 'resolving' via number does not work here despite the manpage says so. ----cut---------cut---------cut---------cut---------cut---------cut----- Proto Protocol name (or number) "tcp" | "udp" | ... ----cut---------cut---------cut---------cut---------cut---------cut----- The following works for IO::Socket::INET if /etc/protocols is not present on the system (see bugreport #185244): perl -MIO::Socket::INET -e '$sock = IO::Socket::INET->new(LocalAddr => "0.0.0.0", LocalPort => 80, Proto => 6);' works and stracing shows that /etc/protocols is not open. Even Proto => "tcp" will work here because of the resolution in [1]. Now trying the same for IO::Socket::INET6: perl -MIO::Socket::INET6 -e '$sock = IO::Socket::INET6->new(LocalAddr => "0.0.0.0", LocalPort => 80, Proto => 6);' gives Use of uninitialized value in hash element at /usr/share/perl5/IO/Socket/INET6.pm line 171. Use of uninitialized value in subroutine entry at /usr/share/perl5/IO/Socket/INET6.pm line 185. and running under strace shows open("/etc/protocols", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) [1]: http://bugs.debian.org/185244 So we need either a Depends on netbase here or a similar implementation (upstream) as for IO::Socket::INET6 where the protocol numbers for tcp, udp and icmp are 'hardcoded', such that reading from /etc/protocols is not needed?

Hi I think I need to specify. Depending in Debian to netbase would be the solution to have always /etc/protocols present. But this is more the request to have it behaving similar to IO::Socket::INET. If protocol names cannot be resolved, and Proto is given as integer, resolve it 'hardcoded' for tcp, udp and icmp. See referenced Bugreport in Debian. Regards, Salvatore
