Palo Alto GlobalProtect on Fedora

After spending some serious time trying to get GlobalProtect 4.1.2 to work on Fedora 28 (and probably 27 earlier this year) I finally managed to get it working. It is almost embarrassing how easy it was…

  1. Replace /etc/redhat-release and /etc/os-release with info from RHEL 7 or CentOS 7
  2. Profit.

Yep….it’s sucky….but at least it shows that this works. Maybe it is possible to modify some file that lists supported operating systems……will have to look into that later on.

Always read the release notes….and the supported OS lists…..and the error logs. Even better if you do it all in the same evening to puzzle this amazing solution together……

FYI: The error I was getting was: Error: Gateway my.gateway.hostname: The server certificate is invalid. Please contact your IT administrator.

Cisco UCS: vHBA bandwidth

I never really understood how Cisco UCS vHBA are configured in regards to bandwidth (coming from a FC background).

Finally I got it spelled out for me like I was five…..IT IS JUST A ETHERNET PORT (yes yes…I knew that. But I really thought there was some more magic involved). IT JUST SYNCS ON THE SAME SPEED AS THE FEX PORT IT IS CONNECTED TO. That would mean if you have a blade with a VIC, a 6332 FI and a 2304 FEX and you do not have the port expander it will be configured as a 20Gbit port (2x10Gbit) with a single flow maxing out at 10Gbit/s (to the FI…not taking into account break out speeds to your ethernet and storage network from the FI). If you have the port expander for the VIC you get native 40Gbit/s if you are using the 2304 FEX and the 6332 FI (single flow can reach 40Gbit/s from the FEX to the FI).

I had a real duh! moment there.

Now it is out there! Hopefully this can help some poor soul out there. I googled my life away for couple of days and did not find a real answer.
