[Solved] ipfw: setsockopt(IP_DUMMYNET_CONFIGURE): Protocol not available

Sandra · #1 April 13th, 2012, 03:02

Hello,

I need to set up DummyNet and I've followed these steps:

Add the following lines to /etc/rc.conf:
Code:
```
firewall_enable="YES"
firewall_type="OPEN"
```
Create a rule

Example:
Code:
```
ipfw add 1000 allow all from any to any
```
Create the pipes

Example:
Code:
```
ipfw add 100 pipe 1 ip from any to any
```
Set up the pipe

Example:
Code:
```
ipfw pipe 1 config bw  100Kbit/s
```

After these steps I checked the ipfw was configured because I typed ipfw list and it showed me the list. However, the pipe wasn't set up and this message was shown:

Code:

ipfw: setsockopt(IP_DUMMYNET_CONFIGURE): Protocol not available

Someone can help me? What other lines I have to add?

Thanks

I'm using FreeBSD-7.4-RELEASE-i386

Please, someone knows if I have to add more lines in the configuration.

Thanks,

That error message means the kernel doesn't have dummynet support enabled.

Do you get output from the following command:
$ ls /boot/kernel/*dummy*

If you don't, then you need to compile a custom kernel with the dummynet options enabled.

If you do, then you need to load the dummynet.ko module:
# kldload dummynet

I don't recall off-hand which version of FreeBSD includes dummynet as a kernel module. It used to be a kernel option that required a complete kernel recompile. At least 9.0 has it available as a loadable module.

Thanks phoenix, I have installed another VMWare image with FreeBSD and DummyNet already set up and now, I can configured the ipfw and pipes. However, I'm facing another problem with the pipes so I'll post another thread for that.

Thanks,
