2010-07-25echo behaves differently in sh and csh, only handling C-style escapesPhilip Guenthe
in the former, so switch an example that needs them to use printf instead. From bcr at freebsd.org. ok halex@
2010-07-03Fix the naming of interfaces and variables for rdomains and rtablesPhilip Guenthe
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.

2010-02-27Fix the atelnet() function, which was wrong in several ways.Nicholas Marriott
Pointed out by obsd at happyjack.org, fix based on a diff from kili@. ok deraadt
2010-02-23Fix the worst among the fatal block-nesting issues we have in our tree,Ingo Schwarze
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@

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@

2005-05-20Teach 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@
