[LDM #FVT-875334]: LDM source IP used when connecting to remote server
- Subject: [LDM #FVT-875334]: LDM source IP used when connecting to remote server
- Date: Thu, 27 Jun 2019 16:24:10 -0600
Robert,
I see what's happening: the ldmd(1) processes that are using IP address
128.117.110.220 are *receiving/downstream" LDM processes that were created as a
result of REQUEST entries in the LDM configuration-file. They use the system's
routing table to determine which interface/IP-address to use at their (local)
end. The bind() system function isn't involved at all.
I'm not sure this is a bug.
You should be able to configure your routing table so that these processes use
the IP address you want.
