set the ttl parameter

[F Verschuren]

Hi, is there a way to set the default Time To Live (ttl) on a hp11.??

I have big a network problem, and the switch specialst of IBM tells me that I have 10 systems whit a ttl of one....

is there a way I can chack this?

Run the following command :

/usr/bin/ndd -h supported

and see if parameters like ip_def_ttl, tcp_ip_ttl,
udp_def_ttl and rawip_def_ttl do what you want
to do. See manpage for ndd(1M) to change the
default values of some of these parameters.

so I can see it like:
[nlscux65:/]# ndd -get /dev/ip ip_def_ttl
255
[nlscux65:/]# ndd -get /dev/tcp tcp_ip_ttl
64
[nlscux65:/]# ndd -get /dev/udp udp_def_ttl
64
[nlscux65:/]# ndd -get /dev/rawip rawip_def_ttl
255
Ore are there more ttl Parameters?
