[pkg-ntp-maintainers] Bug#613318: ntpdate-debian fails when qualifiers are used

[Vincent Lefevre]

Package: ntpdate
Version: 1:4.2.6.p2+dfsg-1+b1
Severity: normal

I have the following problem:

$ ntpdate-debian
14 Feb 03:31:19 ntpdate[22720]: no servers can be used, exiting

The details of the failure:

$ sh -x /usr/sbin/ntpdate-debian
+ set -e
+ [ -r /etc/default/ntpdate ]
+ . /etc/default/ntpdate
+ NTPDATE_USE_NTP_CONF=yes
+ NTPSERVERS=0.debian.pool.ntp.org 1.debian.pool.ntp.org 2.debian.pool.ntp.org 3.debian.pool.ntp.org
+ NTPOPTIONS=
+ [ yes = yes ]
+ [ -r /var/lib/ntp/ntp.conf.dhcp ]
+ [ -r /etc/ntp.conf ]
+ file=/etc/ntp.conf
+ break
+ [ -n /etc/ntp.conf ]
+ sed -rne s/^(servers?|peer) ([-_.:[:alnum:]]+).*$/\2/p /etc/ntp.conf
+ grep -v ^127\.127\.
+ NTPSERVERS=-4
-4
-4
-4
+ exec /usr/sbin/ntpdate -4 -4 -4 -4
14 Feb 03:32:21 ntpdate[22737]: no servers can be used, exiting

I have in my /etc/ntp.conf file:

server -4 0.debian.pool.ntp.org iburst
server -4 1.debian.pool.ntp.org iburst
server -4 2.debian.pool.ntp.org iburst
server -4 3.debian.pool.ntp.org iburst

(because my ADSL modem-router doesn't support IPv6), and the script
takes the -4 qualifier instead of the hostname.

I think the sed line should be replaced by:

  sed -rne 's/^(servers?|peer) +(-[46] +)?([-_.:[:alnum:]]+).*$/\3/p' /etc/ntp.conf
