We have some agents that are unable to connect to Solarwinds. The client was installed, snmp is correctly configured, and the firewall ports 17778 OUTBOUND & 17790 INBOUND have been opened. We have verified that the SW agent is running and has been in communication with the ORION server:
iptables -L | grep 177
ACCEPT tcp -- xxxxxxxxxxxxx anywhere state NEW tcp dpt:17790
ACCEPT tcp -- anywhere xxxxxxxxxx tcp dpt:17778
netstat -naput | grep ESTA | grep 177
tcp 0 0 10.137.6.202:56116 10.137.16.25:17778 ESTABLISHED 18534/swiagent
ps -eaf | grep swi
swiagent 18534 1 0 Mar01 ? 00:00:40 /opt/SolarWinds/Agent/bin/swiagent /detach pidfile=/opt/SolarWinds/Agent/bin/swiagentd.pid
…yet, the agent and the ORION server have not been successful in exchanging the [appropriate handshake], for lack of a better term. The behavior I’ve seen on servers where the agent is working well is that main SW agent process spawns one or two more processes, JobEngine and Discovery.
ps -eaf | grep swi
swiagent 26978 1 28 11:33 ? 00:00:05 /opt/SolarWinds/Agent/bin/swiagent /detach pidfile=/opt/SolarWinds/Agent/bin/swiagentd.pid

We would like to know if there is a better enterprise-grade troubleshooting solution suggested by SolarWinds
Solved! Go to Solution.
Is TLS v1.0 disabled on the target server? The current version of the agent only uses TLS v1.0. That version is upgraded in the next release that is in Release Candidate status now.
