So i have noticed over the last few days that some of my Jenkins slaves are continually reporting in the Windows Event Log the following:
*(Information) **Service started successfully * > > 8:44:04 > > 8:43:58 > > 8:43:51 > > 8:43:44… and so on > > > > *(Information) **Starting C:\Program Files > (x86)\Java\jre1.8.0_91\bin\java.exe -Xrs -jar "c:\Jenkins\slave.jar" > -noCertificateCheck -jnlpUrl > https://---------------------------/computer/D----------------------/slave-agent.jnlp > > -secret * > > 8:44:04 > > 8:43:58 > > 8:43:51 > > 8:43:44… and so on > > > > *(Warning) **Child process [5188 - C:\Program Files > (x86)\Java\jre1.8.0_91\bin\java.exe -Xrs -jar "c:\Jenkins\slave.jar" > -noCertificateCheck -jnlpUrl https://**---------------------**/computer/* > *---------------------**/slave-agent.jnlp -secret **---------------------** > finished > with -1* > > 8:44:04 > > 8:43:58 > > 8:43:51 > > 8:43:44… and so on > As you can see this is happening every 20 - 40 seconds. As far as I can tell Jenkins is working properly and contacting the slaves, as well as running the jobs. Jenkins Slave log shows the following: > INFO: Connecting to > > Jan 19, 2017 5:41:32 AM hudson.remoting.jnlp.Main$CuiListener error > > SEVERE: The server rejected the connection: None of the protocols were >> accepted > > java.lang.Exception: The server rejected the connection: None of the >> protocols were accepted > > at hudson.remoting.Engine.onConnectionRejected(Engine.java:366) > > at hudson.remoting.Engine.run(Engine.java:338) > > >> Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main createEngine > > INFO: Setting up slave: > > Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main$CuiListener <init> > > INFO: Jenkins agent is running in headless mode. > > Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main$CuiListener status > > INFO: Locating server among [https://] > > Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main$CuiListener status > > INFO: Handshaking > > Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main$CuiListener status > > INFO: Connecting to jenkins. > > Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main$CuiListener status > > INFO: Trying protocol: JNLP3-connect > > Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main$CuiListener status > > INFO: Server didn't accept the handshake: Disabled >> protocol:Protocol:JNLP3-connect > > Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main$CuiListener status > > INFO: Connecting to jenkins. > > Jan 19, 2017 5:41:38 AM hudson.remoting.jnlp.Main$CuiListener status > > Some information has been edited, i have removed server names, ports, and URL's *What does it mean to be running in headless mode?* *Yes, i can read that protocols where rejected, how do i fix that?* Any help would be appreciated, Thanks. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
