MUDEC_00327: Failed to connect(AF_SYS_CONTROL) to utun

Technical Support
#1

I’m using mudfish on MacOs and these two errors pop-up [2.781237] MUDEC_00327: Failed to connect(AF_SYS_CONTROL) to utun. and [2.781301] [CRIT] Assert (fd >= 0) failed at ODR_open_tuntapdev (./mud/os/macosx/syscalls.c:741) with 0

Error issues on macOS
#2

Ooops… :frowning: Which Mac OS X version are you using? And are you running another VPN program on mac too? This error means that it failed to create utun(4) interface. But it seems it doesn’t show details. Please check ‘Status -> Process’ menu to see “Core” log section. It’ll include some details about why.

#3

I’m using Mac OS Catalina version 10.15.6 and im not using another vpn program, just mcafee virus protection. I’m not really good with computer things, should I just send what it says to you?

#4

Please check ‘Status -> Process’ menu to see “Core” log section and show me the full logs of core part. :slight_smile: I think it’ll include some more detailed error codes to analyze your issue. Sorry for this inconvenience.

#5

I think it has fixed itself cause there is a tick next to the “core” but when I go to check on myip.mudfish.net, it says im not connected to mudfish… here’s the log of the core part

Okay. :slight_smile: When I checked this problem report, it seems your crash issue is now solved.

Did you equip “What’s my IP?” item? If you’re not using Full VPN mode, it’s required to equip before visiting https://myip.mudfish.net
