RE: [webmin-l] Webmin Servers, Broadcast/scan

[Neal M. <Ne...@mo...>]

Jamie:

Short answer: ethereal shows it still using port 10000 for broadcast.

Long answer: I first set the UDP port to 6789, ran a netstat to confirm
a listener was in place there are none existed on 10000, then ran the
broadcast.


On the multihome: the IPs resolve to different hosts and FQDNs. =20

Both servers have 2 NICs:

10.X.X.X/255.255.255.0=20
66.X.X.X/255.255.255.224

Webmin broadcasts correctly to the expected two network addresses:

10.X.X.255=20
66.X.X.223

But it also adds in a broadcast to all networks, and a broadcast to the
10 net as a class A:

255.255.255.255
10.255.255.255

Ethereal shows the 10.255.255.255 ignored (not on my network), the
10.x.x.255 received by the first NIC, and the 66.X.X.223 and
255.255.255.255 received by the second NIC.

So - it should receive 3 responses.  Somehow, it is already de-duping
them and concluding there are 2 new servers to add.  I'm OK with that -
except it uses the same host name and port for both.  So, there is
nothing I can see from the edit screen that indicates why it thinks they
are different. =20

Furthermore, if I broadcast again, I would expect it to either re-add
both, or add nothing.  Instead, it adds just one of them!  Every new
broadcast adds one more server with the same name, same config settings.


Hope that helps and wasn't too much information.



Thanks,

Neal
