How do we secure the address of the source of the packages leaving the interface?
On eth0, a number of ips rise. Let's pass file /etc/network/interfaces:
auto eth0 iface eth0 inet static address 100.100.100.100 netmask 255.255.255.0 auto eth0:1 iface eth0:1 inet static address 100.100.100.101 netmask 255.255.255.0 auto eth0:2 iface eth0:2 inet static address 100.100.100.102 netmask 255.255.255.0
If you look at the routing table, you see the following records.
$ ip route show default via 100.100.100.1 dev eth0 100.100.100.0/24 dev eth0 proto kernel scope link src 100.100.100.102
The challenge is that always meaning src 100.100.100.102 It was the ip I'd say (and it was permanent). I can do it manually through the team.
ipbut it'll only be until the first reboot of the server or the command call.
service networking reload
How can this be done literate, given that the number of ips can be more than 100 on one interface?
And if you set up a routing table, again through the team.
ipBut it only exists before the first reboot.

n. network interface aliases programme subsystem linux 15-16 years ago, I've been doing a normal configuration without this heavy legacy, but if you want, just finish the configuration. alias-ami♪
The challenge is that I want the meaning of src 100.100.100.102 to be that ip I will tell you (and it was permanent).
And point it out clearly.
auto eth0 iface eth0 inet static address 100.100.100.100 netmask 255.255.255.0 up ip a a 100.100.100.101/24 dev $IFACE up ip a a 100.100.100.102/24 dev $IFACE up ip r c 100.100.100.0/24 dev $IFACE src 100.100.100.102
Reductions used (may be written and completely, just so short):
ip a a=
ip address add
ip r c=
ip route change
on " Complementing alias-ami" .
If they're so necessary, it's easier to tell them. alias- (in programme terminology) ip - marks, labels(a) Direct arguments of the programme ip:
ip a a ... label $IFACE:0
