Need help for route command

[manjuks]

Hi All,

I need help to port below command to LINUX, it was written for Solaris platform

$cmd = "/usr/sbin/route [B]-n[/B] add [B]-host[/B] $hoc [B]-gateway[/B] $gatewayIp [B]-setsrc[/B] $vcip";

In Linux route command exists, and these add gateway options are available. But last option -setsrc is not available in LINUX. It represents “Assigns the default source address”, I didn't understand clearly... Can any one please explain me what it represents? I had gone through man page and searched in net, But could not get anything.

It would be great help if you can guide me how I can port this to Linux OS.

Thanks in advance

If you have multiple interfaces for same network.
Say, eth0 172.18.28.90 and eth1 172.18.28.91. In this case, solaris will choose first working device as a output interface. If you have to change the interface for all output traffic then you basically specifies with -setsrc switch.

In case of linux, just specify eth0 or eth1 whichever you may need. If you have only single interface don't bother about those options.

something like this:

route add default gw 172.18.28.1 eth0

Hi ashitpro

Thanks for your reply..

Shall I replace this

$cmd = "/usr/sbin/route -n add -host $hoc -gateway $gatewayIp -setsrc $vcip";

With this...

$cmd = "/sbin/route -n add -host $hoc -gw $gatewayIp" ;

$dev = `netstat -ie | grep -B1 135.254.239.52  | head -n 1 | awk '{print $1}'`;

$cmd = "/sbin/route add default gw $vcip $dev;

Thanks,
Manju
