[Swan-dev] What happened to "ipsec show" ?

[Brady Johnson]

Ok, I made some progress with this.

Here is the output of the existing "ipsec connectionstatus" command:

000 Connection list:

000
000 Total IPsec connections: loaded 1, active 1

And here is the output of the new command I added:

ipsec briefconnectionstatus
000 Connection list:
000
000 "vpnclient.gwn02.xyz.com": 172.16.20.0/24===172.22.18.102[O=XYZ, CN=
vpnclient.gwn02.xyz.com]...172.22.18.101[O=XYZ, CN=vpnserver.gwn01.xyz.com
]===172.16.10.0/24;
000
000 Total IPsec connections: loaded 1, active 1

This still seems a little verbose, but I think it provides just enough
info. If somebody wants more info, they can just use the "ipsec
connectionstatus" command.

Regards,

Brady
