2005-07-24correct rval check for socket(). from alf schlichting. ok markus@marius eriksen
2005-07-17oops... .Dl does not like to be inundated with args, and my last commit justJason McIntyre
exceeded the happy number - use a display instead.
2005-07-17some improvements from alf schlichting:Jason McIntyre
- 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
2005-05-28set jumbo flag on the listener, too. consolidate some common code.marius eriksen
ok mcbride@
2005-05-27Experimental support for opportunitic use of jumbograms where only some hostsRyan Thomas McBride
on the local network support them. This adds a new socket option, SO_JUMBO, and a new route flag, RTF_JUMBO. If _both_ the socket option is set and the route for the host has RTF_JUMBO set, ip_output will fragment the packet to the largest possible size for the link, ignoring the card's MTU. The semantics of this feature will be evolving rapidly; talk to us if you intend to use it. ok deraadt@ marius@

2005-05-24Switch atomicio to a simpler interface which returns size_t and usesAnil Madhavapeddy

2005-05-20Teach the SOCKS5 code more of the protocol, so it can send domain namesDamien Miller
to the proxy instead of resolving them locally and sending IPv4 addresses. This improves privacy, e.g. when using nc with OpenSSH DynamicForward tunnels, and gives us better IPv6 support; ok beck@

2002-12-13Recent modifications to netcat changed the behaviour to only exit when bothAaron Campbell
the read (network) and write (stdin) ends of the socket were both closed. This is not how nc traditionally works. Instead, revert back to finishing up when read() on the socket returns 0; deraadt@, vincent@ ok.

this allows stuff like nc -l 10101 < /dev/null to have nc exit automatically when it gets EOF from the network. ok ericj@
