FreeBSD Enable PF ALTQ Firewall Support

Posted on in Categories , , , , last updated October 2, 2008

Q. Under FreeBSD 7.0 patch level 5, I’m getting following warning message:

Enabling pf.
No ALTQ support in kernel
ALTQ related functions disabled
No ALTQ support in kernel

I need ALTQ support for my FreeBSD box. How do I enable ALTQ for Class Based Queuing (CBQ) to divide a connection’s bandwidth into different classes or queues to prioritize traffic based on filter rules?

Posted on in Categories , , , , , , , , , , , , , , , last updated July 15, 2008

I’ve couple of remote servers and I’d like to access few admin only application running on port 10000 and 3001. My firewall only allows port 80, 443, 25, 22 and 110 for public access. Do I need to open port 10000 and 3001 for everyone using firewall? How do I access my admin only apps without opening port 10000 and 3001?

I‘m trying to get data (AXFR query) from master tinydns server to secondary DNS server using tcpclient as follows:
tcpclient -v a.ns.example.com 53 axfr-get example.com example.com example.com.tmp

But I’m getting an error which read as follows:

How do I fix this problem?
