„The times they are a-changing“ – Bob Dylan<\/em><\/p>\n\n\n\n

however grave the problems were that dylan addressed<\/a> in his song and 1963 album, he certainly didn’t envision how linux distributions like debian are a-changing the way in which we have to configure our network settings. if we look at how we define static ip addresses, we can see quite some dylan-esque transitions. and when you need to persistently define static routes<\/strong>, keeping up-to-date can be at least hard.<\/p>\n\n\n\n

it’s been hardly nine months since my post about static routes in debian 9<\/a> when that method has been marked as „deprecated“ and won’t actually work anymore in debian 10 „buster“. So here’s how to do both static ip and static routes<\/strong> in buster:<\/p>\n\n\n\n

the good thing is, it’s now all in one file. just edit \/etc\/network\/interfaces. for the not-so daring types, make a backup before the edit: <\/p>\n\n\n\n

> sudo cp \/etc\/network\/interfaces \/etc\/network\/interfaces.orig<\/code>

> sudo vi \/etc\/network\/interfaces<\/code><\/pre>\n\n\n\n
an out-of-the-box install will most certainly have dhcp configured. So for static ip, we comment out (or delete) these lines:<\/p>\n\n\n\n
# allow-hotplug ens18<\/code>
# iface ens18 inet dhcp<\/code><\/pre>\n\n\n\n
ens18<\/code> is the interface name in this example. that can be eth0<\/code> or en0<\/code> or something else in your case. <\/p>\n\n\n\n
In order to set the static ipv4 address<\/strong> for the machine, insert this:<\/p>\n\n\n\n
# static ip address on interface ens18 (or whatever the name):<\/code>
address 192.168.1.100<\/code>
netmask 255.255.255.0<\/code>
gateway 192.168.1.1<\/code>
dns-domain fritz.box<\/code>
dns-nameservers 192.168.1.1 8.8.8.8<\/code><\/pre>\n\n\n\n
…of course you have to adapt the adress scheme to your network setup.<\/p>\n\n\n\n
right after this we’ll add the static route <\/strong>which has been moved from the route<\/code> system command to the more general ip<\/code> tool:<\/p>\n\n\n\n
# for a network route:<\/code>
up \/bin\/ip route add 192.168.10.0\/24 via 192.168.1.10<\/code>

# and for a host route:<\/code>
up \/bin\/ip route add 192.168.10.10\/32 via 192.168.1.10<\/code><\/pre>\n\n\n\n
of course you know that the latter – a host route – is merely a special case of the more general classless routing notation above…<\/p>\n\n\n\n
ok, my little furry creatures. till next time in our series „fun with the a-changing linux concept of static routes“. <\/p>\n","protected":false},"excerpt":{"rendered":"
