dear all,

maybe i misunderstand this command. if i drop one interface all others disappear.
is this what it should do ? ( see below )
my environment: sun sparc solaris 10 with ntp version 4.2.8p2
my sparc server has 4 nic's. 3 of them are cabled, plumbed and up. no virtual interface.

kind regards
hans
