[SunHELP] Retrieving routing table entries

[Amudhavalli Narayanan]

hi,
Thanks for the help. I think I will have to parse the netstat output only.

Regards,
Amudha

Sorry, I didn't understand you were looking for an API.

Well, I doubt you can get the route table from any socket syscall, as the
routing
table are kernel global datas.

I launched "netstat -r" with "truss" to know how netstat got theses values.
It seems "netstat" uses some ioctl calls to "/dev/kstat" (the kernel stats
facility)
to get this :

10752/1:        open("/dev/kstat", O_RDONLY)                    = 3
10752/1:        ioctl(3, KSTAT_IOC_CHAIN_ID, 0x00000000)        = 3802
10752/1:        ioctl(3, KSTAT_IOC_READ, "kstat_headers")       = 3802

Reading kstat(3K) man page will give you more informations, but it seems
this is a painfull job.
The libkstat library offers some facilities to handle the job (see the
manpages
for kstat_open(3K), kstat_lookup(3K), etc.).

I guess it should be easier to call popen("netstat -r", ...), and then parse
the output.

Good luck indeed...

	"netstat -r" is the usual way to get this, whatever Unix you have.
	Note that it works under MSWindows too.

		Hi,
		I want my application to retrieve all routes from the
routing table.
	Are
		there any standard system calls (something like sysctl in
unix as )
	that I
		can use in Solaris 8?(as sysctl is not supported in Solaris
upto my
		knowledge)

		Regards,
		Amudha
