* Support unix domain sockets in nc(1) with -Uu.jeremy2011-01-081-2/+16
| | | | | | | | | | | | | | | | | | | | | Previously, using -U with -u was an error that was not documented in the man page. Now it will use a unix socket in datagram mode. Bidirectional unix datagram communication requires a socket at both ends, so in client mode (without -l), a temporary socket is created so that responses from the server can be received. If -s is specified with -U and -u, it specifies the location of the temporary socket to create. This was mostly written way back in 2007. Since then, various improvements implemented based on suggestions from guenther@, tedu@, and nicm@. Man page help from nicm@ and jmc@. Unix datagram support requires a small change to atomicio.c in order to function correctly, this will be committed separately shortly. OK nicm@
* echo behaves differently in sh and csh, only handling C-style escapesguenther2010-07-251-3/+3
| | | | | | in the former, so switch an example that needs them to use printf instead. From bcr at freebsd.org. ok halex@
* Fix the naming of interfaces and variables for rdomains and rtablesguenther2010-07-031-5/+5
| | | | | | | | | | | | and make it possible to bind sockets (including listening sockets!) to rtables and not just rdomains. This changes the name of the system calls, socket option, and ioctl. After building with this you should remove the files /usr/share/man/cat2/[gs]etrdomain.0. Since this removes the existing [gs]etrdomain() system calls, the libc major is bumped.

* Fix the worst among the fatal block-nesting issues we have in our tree,schwarze2010-02-231-4/+4
| | | | | | | | | | | | in the end simply changing Oo Xo Oo Oc Oc Xc to Oo Xo Oo Oc Xc Oc. I tried five different variants without the Xo/Xc, because there is no real reason why Xo/Xc should be needed here, and two additional variants with Xo/Xc that look more pretty than what i'm now committing. All seven alternatives work both with mandoc and groff 1.20.1, but all seven trigger various different bugs in our old groff, and we still need to remain compatible with our old groff right now. ok jmc@ sobrado@

* some improvements from alf schlichting:jmc2005-07-171-14/+11
| | | | | | | | | | - correct syntax for retrieving an http page. this example further corrected by ian darwin (thanks!) - the -v flag is relatively useless when port scanning, so remove it from the example, and reword the description appropriately - udp port scans always report ports as open (i.e. are useless) so remove example claiming it works, and add CAVEATS to note that -uz is relatively useless
