Can I ping via an arbitrary interface of a DD-WRT system?
- by bytebuster
There's a Linksys WRT54GL router with DD-WRT firmware (v23SP2).
The network has a simple dual-WAN configuration (standby mode, switching by a script):
~ # ip route
192.168.3.0/24 dev br0 proto kernel scope link src 192.168.3.1
192.168.2.0/24 dev vlan2 proto kernel scope link src 192.168.2.2
192.168.1.0/24 dev vlan1 proto kernel scope link src 192.168.1.67
127.0.0.0/8 dev lo scope link
default via 192.168.2.1 dev vlan2
I'm trying to ping a certain server arbitrary via vlan1 or vlan2.
What I tried, as suggested here:
ping -I vlan2 <address>
ping 192.168.2.1 <address>
In both cases ping simply exits with no error messages.
Also, ping ignores many other parameters, again, by exiting silently.
I failed to find any references that DD-WRT has a limited version of ping whatsoever.
I also don't think it can be a permissions issue as mentioned here since the only user with DD-WRT is root.
What's wrong?
