Package: tcputils
Version: 0.6.2-6
Severity: important
Tags: patch
The 64-bit binary of "tcpconnect" is failing to connect when given a
hostname, reporting "Network is unreachable". It works fine when given an
ip address. It appears this is because the code in
ip/tcp_open.c:tcp_open() is comparing the result of a call to inet_addr()
with "(unsigned long)-1)" where I'm thinking it should be comparing instead
to "INADDR_NONE" according to the docs for inet_addr I found on the web (I
didn't seem to have a manpage for inet_addr on the debian box). There
might well be other parts of the code that have issues with 64-bit, though.
