disable interface

[Reinhard Bayer]

Hi folks

There is one phy. interface with two IP-Addresses assigned but sometimes I need to disable one of these locigal interface on my HP-UX 11.00 box. I did an "ifconfig lan0:1 down" and than an "ifconfig lan0:1" for verification purpose. The result looks fine:

ifconfig lan0:1
lan0:1: flags=842

but the ping on that interface still works.

ping x.x.x.x
PING x.x.x.x: 64 byte packets
64 bytes from x.x.x.x: icmp_seq=0. time=0. ms

traceroute x.x.x.x
traceroute to x.x.x.x (x.x.x.x), 30 hops max, 20 byte packets
1 x.x.x.x (x.x.x.x) 0 ms 0 ms 0 ms

Traceroute shows me also that the interface on the local system is used.

How can disable the Interface?? And how can i prevent the internal use ( internal means, from the box itself)

Thanks in advance

Hi Reinhard,


Just issue
ifconfig lan0:1 0

That will remove the additional ip address configure (check with netstat -ain). You don't need to issue ifconfig lan0:1 down to remove it.

Hi Reinhard Bayer

or if you still are not staisfied , discoonect the lan cable to the interface physically.
