Bug Description

Binary package hint: netcat-openbsd

Netcat-openbsd does not echo response from xinetd UDP server to stdout. But netcat-traditional works OK as with TCP server.

Test case:

Install xinetd and enable the builtin services in /etc/xinetd.d/. Do the following:

$ /bin/nc.traditional -u localhost echo
hehe
hehe
haha
haha
^C
$ /bin/nc.openbsd -u localhost echo
hehe

$

Since in netcat-openbsd README.Debian, it says "Anything else that netcat-traditional does that this package doesn't is a bug." So I file this as a bug.

The version is 1.89-3ubuntu5 in Natty.

This bug applies to netcat for all the builtin services of xinetd, they are chargen, daytime, discard, echo and time.
