IPs Ping but missing from IFCONFIG

Bashed · 11-25-2016, 07:45 AM

I ran a script below to route 20 x /24 subnets for VPN use.

Code:

for i in $(seq 2 254);
        do ip addr add xxx.xxx.3.$i/24 dev em1
        ip addr add xxx.xxx.58.$i/24 dev em1
        ip addr add xxx.xxx.65.$i/24 dev em1
        ip addr add xxx.xxx.80.$i/24 dev em1
        ip addr add xxx.xxx.90.$i/24 dev em1
        ip addr add xxx.xxx.21.$i/24 dev em1
        ip addr add xxx.xxx.31.$i/24 dev em1
        ip addr add xxx.xxx.30.$i/24 dev em1
        ip addr add xxx.xxx.40.$i/24 dev em1
        ip addr add xxx.xxx.50.$i/24 dev em1
        ip addr add xxx.xxx.60.$i/24 dev em1
        ip addr add xxx.xxx.70.$i/24 dev em1
        ip addr add xxx.xxx.81.$i/24 dev em1
        ip addr add xxx.xxx.1.$i/24 dev em1
        ip addr add xxx.xxx.6.$i/24 dev em1
        ip addr add xxx.xxx.16.$i/24 dev em1
        ip addr add xxx.xxx.17.$i/24 dev em1
        ip addr add xxx.xxx.29.$i/24 dev em1
        ip addr add xxx.xxx.34.$i/24 dev em1
        ip addr add xxx.xxx.70.$i/24 dev em1        
done

ip addr show

They all ping fine, but ifconfig output does not list them.

I'd like to fix that and need someone's help please.

I have never tried what you are doing, however you are using ip to add addresses. So why use ifconfig to view.
Try:

Code:

ip a

Not sure if that will work, but there is also

Code:

route

Hopefully one of those will get you what you want

If they do ping then I'd have to ask what is the use of ifconfig to again prove it is working.

Might as well also ask what command did you use exactly and did you use sudo?
