>Description:
The freebsd-update script tries to find mirrors using SRV records. My Mikrotik
router with built-in nameserver gives the following output:
# host -t srv _http._tcp.update.FreeBSD.org
_http._tcp.update.freebsd.org has SRV record 1 35 80 update4.FreeBSD.org.
_http._tcp.update.freebsd.org has SRV record 1 50 80 update5.FreeBSD.org.
_http._tcp.update.freebsd.org has SRV record 1 5 80 update3.FreeBSD.org.
The first part is converted to lowercase. The freebsd-update script checks
(with sed) for "_http._tcp.update.FreeBSD.org", but that does not match the
lowercase output.
freebsd-update is unable to find the mirrors, and freebsd-update fails.
The workaround for this problem is to change the Servername in
/etc/freebsd-update.conf to all lowercase.
>How-To-Repeat:
Use a mikrotik router as nameserver or any other nameserver that returns the
requested hostname in lowercase instead of the original casing.
>Fix:
Make the regular expression - used to strip away the
"_http._tcp.update.freebsd.org has SRV record " - case insensitive:
Change:
sed -nE "s/${MLIST} (has SRV record|server selection) //p"
to
sed -nE "s/${MLIST} (has SRV record|server selection) //Ip"
