[SOLVED] Update to 24.1 AT&T Supplicant Bootup issue

[the1corrupted]

Hello!

I wanted to re-do my firewall configuration and setup for a bit of practice, and for some reason the same scripts I have for PFATT don't quite work the way they used to and I swear I'm missing a step.

It's all straight forward, I have the supplicant certificates, and everything in the script works outside of bootup time.

I can't seem to find the errors encountered on startup, and I feel like there was something to remove "re1" (my WAN interface) from being "accidentally used" in the old 23 version.

Again, all of this "works" just requires manual intervention for the script to actually run/work.

From previous instructions, this script is located at /usr/local/etc/rc.syshook.d/early/99-opnatt

Code: [Select]

#!/usr/bin/env sh
#
# CONFIG
# ======
#
# ONT_IF                  Interface connected to the ONT
#
# RG_ETHER_ADDR           MAC address of your assigned Residential Gateway
#
# EAP_MODE                EAP authentication mode: supplicant or bridge
#
#    supplicant           Use wpa_supplicant to authorize your connection.
#                         Requires valid certs in /conf/pfatt/wpa. No
#                         Residential Gateway connection required.
#
#    bridge               Bridge EAPoL traffic from your Residential Gateway to
#                         authorize your connection. Residential Gateway
#                         connection required.
#
# EAP_SUPPLICANT_IDENTITY Required only with supplicant mode. MAC address associated
#                         with your cert used as your EAP-TLS identity. If you extracted
#                         the cert from your stock issue residential gateway, this is the
#                         same as $RG_ETHER_ADDR.
#
# EAP_BRIDGE_IF           Required only with bridge mode. Interface that is connected
#                         to your Residential Gateway.
#
# EAP_BRIDGE_5268AC       Required only with bridge mode. Enable workaround for 5268AC.
#                         Enable if you have the 5268AC. See https://github.com/aus/pfatt/issues/5
#                         for details. 0=OFF 1=ON

I solved the problem.

The script didn't have execute permissions, and was getting "permission denied" during startup. chmod +x /usr/local/etc/rc.syshook.d/early/99-opnatt fixed the boot time issues.

Because of the failed boots, it was using fall back WAN interface (which doesn't work). Re-bind WAN interface to ngeth0, reboot again, and now it's working.
