 TCP wrapper question I just installed TCP wrappers 7.6 and now every time I try to connect from a host that should be allowed, I get disconnected and in syslog a message like "refused connection from 0.0.0.0" appears. If I change it so that all hosts are allowed to connect, then I see "connection from 0.0.0.0" in syslog. Why does the TCP wrapper program think that all my hosts have 0.0.0.0 as an IP address? How do I fix that?      |

How do I fix that? My guess is that you need the IPv6 aware version of TCP Wrappers, as modified by Casper Dik. Google will show where to get it. -- Rich Teer, SCNA, SCSA President, Rite Online Inc.

How do I fix that? The solaris FAQ says: 4.17) Where can I get an IPv6 capable version of tcp wrapper? The IPv6 capable version of tcp wrapper is available at Wietse's site in the /pub/ipv6 directory. <ftp://ftp.porcupine.org/pub/ipv6/> Make sure you configure it with -DHAVE_IPV6. Solaris 9 has this version of tcp wrappers bundled with the system. 5.85) Tcpd prints "connect (refused) from 0.0.0.0" in Solaris 8 and later? The default inetd configuration in Solaris 8 and later have changed the service type for most services from tcp/udp to tcp6/udp6. You'll either need to change them back to tcp/udp or better, upgrade your tcp wrappers to an IPv6 capable version as described in 4.17. --- end of excerpt from the FAQ The most recently posted version of the FAQ is available from <http://www.science.uva.nl/pub/solaris/solaris2/> |
