Command allowlist can be by these symlinks
ln -s /usr/bin/distcc /usr/lib/distcc/x86_64-pc-linux-gnu-gcc
ln -s /usr/bin/distcc /usr/lib/distcc/x86_64-pc-linux-gnu-g++
Also check symlink exists in /usr/lib/distcc which is used as whitelist, I suppose
Make symlinks on server as we ha a special CHOST from /etc/portage/make.conf (This would cause 110 exit code)
ln -s /usr/bin/x86_64-linux-gnu-gcc /usr/bin/x86_64-pc-linux-gnu-gcc
ln -s /usr/bin/x86_64-linux-gnu-g++ /usr/bin/x86_64-pc-linux-gnu-g++
ln -s /usr/bin/gcc /usr/bin/x86_64-linux-gnu-gcc
ln -s /usr/bin/g++ /usr/bin/x86_64-linux-gnu-g++
ln -s /usr/bin/gcc-13 /usr/bin/gcc
ln -s /usr/bin/g++-13 /usr/bin/g++
Install symlinks on client update-distcc-symlinks
ln -s /bin/distcc /usr/lib/x86_64-pc-linux-gnu-gcc
ln -s /bin/distcc /usr/lib/x86_64-pc-linux-gnu-g++
Restart service
service distcc restart
Check rolling log on server
tail -f /var/log/distcc.log
Verify permissions if empty.
Check messages on client
export DISTCC_VERBOSE=1
pump make -j 20
