Steven very kindly was able to share a copy of that blog post, unfortunately it doesn't help. He had explained how to allow Apache to open TCP connections to localhost:1085, instead of everything. I first tried opening it to all and it still didn't work, so this more restrictive method will not help.

At the bottom of https://wiki.wocommunity.org/display/documentation/Deploying+on+Linux there is a section on SELinux. It points to a blog post written in 2013 by Steven Klassen, unfortunately that blog post is no longer available, does anyone have the original ?  I've emailed Steven to see if he can send it to me.

I've tried to add 1085 as an allowed http port using semanage, but I'm not sure I'm taking the right steps.

I'm home and was able to test. It's not the firewall (I turned it off for a couple of minutes and tried, without success). I'm not sure what policies to look at. As far as I know wotaskd does not keep a log, correct ?

Hi Samuel,
that is a very good insight. I'm currently travelling, but when I'm back I'll play with policies/firewall and let you know what I found out.

Thanks,

Hi Valerio,

I experience the same problem on a Cent OS instance (I think this is a VMWare distribution) but it works on others...

There is a major difference between starting the instance and other function like stop and refuse new session. Start is done by wotaskd that launc the process, others are http call to the instance by wotaskd, to some direct actions (womp handler I think).

I suspect that the communication between wotaskd and instance is blocked by the firewall or system policy but I do not have a definitive proof of this.

Regards,

Samuel

Thanks Lon,
I didn't see your answer until now because gmail (which I hate every day more) had hidden it.

I'll see what I can find in the logs, although "start" works fine, why would "stop" be different ?

Look in your application log, do you see messages about not being able to communicate with monitor?  I found this problem happens if I don't have JavaXML as part of my project (or classpath defined to whatever the xml jars are).

I recently ported my WebObjects app from an old OS X server to a CentOS 8 server.

The WOMonitor on CentOS allows me to configure the app and start it, but it will not stop it (I end up doing with pkill from command line) and the Auto-Recover does not work. I also tried from command line using curl to communicate to WOMonitor, it does the info and start correctly, but it will not stop the app.

I've looked at the log file for the WOMonitor, but there was nothing useful.

Any ideas ?

Thanks in advance,
