HP ILO 4 on macOS Moterey w/Java applet fails with telnet.connect() SocketException: java

[RobbieTheK]

Does Telnet TCP port 23 really need to be open? I see an old thread that mentions it needs to be open. Another thread mentions having to open port 23 within their DMZ. I added the URL to the Java Control Panel. In /etc/pf.conf I added:

pass in proto tcp from any to any port 23
pass in proto tcp from any to any port 1999

In the Java console I see these logs:

Exception: java.io.FileNotFoundException: /Users/rk3199/.java/hp.properties (No such file or directory)

However it looks like 23 won't open:

nc -vnz 127.0.0.1 1999
Connection to 127.0.0.1 port 1999 [tcp/*] succeeded!

nc -vnz 127.0.0.1 23
nc: connectx to 127.0.0.1 port 23 (tcp) failed: Connection refused

Any tips to getting this to work?

No but I am getting closer with one of the links I shared in my original post. Would there be a way as a 1 time courtesy to get a BIOS download for this?

Hello,

You will need active warranty/contract to download the BIOS.

Please do log a case using the below link for exceptions(if any).
