# CHANGE HISTORY
|
|
# 2021/4/8 avoid setting PATH in scripts for root
|
|
# 2021/5/31 whereis used without -b in OpenBSD and NetBSD
|
|
# Corrected: bridge create and fwdelay done twice for NetBSD
|
|
# FreeBSD: tapX opened by userland program not by ifconfig
|
|
# 2021/11/17 check for existance of br0 done too lousy. Done better.
|
|
# 2021/12/29 Linux: when nmcli available: permanent setup using NetManager.
|
|
# 2023/4/19 Let ResetNet also remove tap2, tap3 as requested
|
|
# 2023/7/28 When nmcli is used check that br0 does not already exist
|
|
# Use $nmcli in SetupNet and in the generated scripts too
|
|
# Text changed to be more clear: we are building br0/tap0 with an external i/f
|
|
# When nmcli used: code to delete current ext i/f is same CMD construct as other
|
|
# When nmcli used and ResetNet created: let it remove orphaned connections too
|
|
# When nmcli used and ResetNet created: recreate original interface by type and name
|
|
# When nmcli used: correctly detect WiFi interfaces and ignore it for now
|
|
# 2023/7/30 User prompted for loading saved params from SnetSaved.interface file
|
|
# Entered params only saved when no SnetSaved.interface file exists.
|
|
# Removal of generated script /tmp/SNjob.pid after exec now optional.
