				The

				program is designed to help you list and control what TCP functions
				jtlUnsubmitted Not Done Inline Actions I'm curious why you chose to create a new program, rather than making the sysctls allow changes directly? jtl: I'm curious why you chose to create a new program, rather than making the sysctls allow changes…
				rrsAuthorUnsubmitted Not Done Inline Actions Can you do a sysctl that accepts a string? Or a sysctl that prints out a structure like the list does? If so I would be glad to do that... rrs: Can you do a sysctl that accepts a string? Or a sysctl that prints out a structure like the…

				rrsAuthorUnsubmitted Not Done Inline Actions Ok I can do this.. but I am not sure I want to. I have to change it so you do not get the count out.. hmm I suppose I could just build the lines and send them back with the number of pcb's as well... Let me mull on this to see if I really want to do that. Maybe for getting and setting the default, but I think the list function needs to stay like it is so you can know the number of pcb's as well. rrs: Ok I can do this.. but I am not sure I want to.

				may load kernel loadable modules which add different TCP behaviors
				through new functionality. Each set of functionality is named by
				the designer. Once the module is installed it makes available new
				functionality. You may use the
				.Nm
				progam to list, enquire which function set is the default, or set
				a new default function set. The default function set is the one
				that any new TCP connection will use. Users may also use the
				TCP_FUNCTION_BLK socket option to change a specific TCP socket
				at startup.
				.Sh OPTIONS
				The following options are available:
				.Bl -tag -width indent
				.It Fl l
				List out the current TCP function sets installed on this machine and
				give an account of the number of PCB using it.
				.It Fl d
				List the default TCP function set that will be used if no socket
				option is specified by the program.
				.It Fl s Ar name
				Set the default TCP function set to name.
				.Sh SEE ALSO
				.Xr tcp 4
				.Sh HISTORY
				The
				.Nm
				utility first appeared in
				.Fx 11.0.
