 Posted: Wed Sep 07, 2011 6:46 am Post subject: Bind9 complaining about lack of threads support |
 |
|
Just found an interesting issue with bind after an update. Starting bind with:
| Code: | start-stop-daemon --start --pidfile /var/run/named/named.pid --nicelevel 0 --exec /usr/sbin/named -- -u named -n 2
|
Leads to the following error:
| Code: | | named: -u with Linux threads not supported: no capabilities support or capabilities disabled at build time |
Bind was built with threads support so this confused me a little. Removing "-u named" and running as root worked just fine.
Turns out its due to lack of the "caps" user flag but this is not obvious from the error.
Posting this in-case anyone else has the same issue, just add the caps use flag and it should run as a non-root user once again.
My bind use flags:
| Code: | [ebuild R ] net-dns/bind-9.8.1 USE="berkdb caps dlz geoip gost gssapi ipv6 ssl threads xml -doc -idn -ldap -mysql -odbc -pkcs11 -postgres -rpz -sdb-ldap (-selinux) -urandom" 0 kB

haven, thanks for posting!
had the same error message and couldn't figure out what was going on.
| Code: | named: -u with Linux threads not supported: no capabilities support or capabilities
disabled at build time |
simply enabling caps flag and I am back to a working NS in a
non-root setup. saved a lot of digging! |
