Hey folks
I've had a setup with xtables-addons running (on jessie with standard
repos), especially the geoip module in this case. The normal upgrade
path installed gcc-4.9 and broke my dkms setup and in turn my iptables
setup. So it fell back on my fail2ban protection against ssh scripts.
/usr/bin/gcc-4.8 was on strange file permissions, with not even execute
perms for root. Thus de dkms rebuild failed.
now my questions:
why was gcc-4.8 binary set to no execution, even for root?
why is xtables-addons-dkms not using gcc-4.9?
a simple chmod 700 /usr/bin/gcc-4.8 fixed the problem.
Thank you for any enlightenment
best regards
