Package: isc-dhcp-client
Version: 4.3.1-5
Severity: important
Dear Maintainer,
With a server supplying this route configuration, dhclient-script
fails and dhclient enters an endless loop.
option rfc3442-classless-static-routes 24, 192, 168, 122, 172, 16, 172, 100, 0, 0, 0, 0, 172, 16, 172, 1;
option ms-classless-static-routes 24, 192, 168, 122, 172, 16, 172, 100, 0, 0, 0, 0, 172, 16, 172, 1;
dhclient output:
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 5
DHCPREQUEST on eth0 to 255.255.255.255 port 67
DHCPOFFER from 172.16.172.100
DHCPACK from 172.16.172.100
/sbin/dhclient-script: 35: shift: can't shift that many
DHCPDECLINE on eth0 to 255.255.255.255 port 67
<repeat>
Note that I don't know if the static routes as given are a valid
configuration - I was experimenting with this when trying to
work around #764219.
Thanks,
Christian
