For example, I'm connecting to 192.168.123.254 via telnet (port 23), and do tcpdump -nli rl0. This cyclic traffic, becuase when tcpdump outputs something, the system sends me some packets, which generates output in tcpdump, and vice versa. I want to filter out packets of telnet access to the FreeBSD machine, that is, something like: tcpdump -nli rl0 | grep --non-matching-lines 192.168.123.254.23 % tcpdump -nli rl0 | grep -v 192.168.123.254.23 will print everything except the IP you have shown. Actually, a better way to do it would be: % tcpdump -nli rl0 'not host 192.168.123.254 and port 22' Will prevent tcpdump from capturing your own SSH traffic. grep -v is only a partial solution, if a switch such as '-X' (or '-x' on some platforms) is added, grep -v will snip only the matching line, leaving all the other lines that don't match, through, which will generate traffic, get captured, and loop as previously, as well as making the output look very non-sensical. 'man tcpdump' will be a better read in this case than man grep, although the question was perhaps worded poorly, leading to responses on grep.

When in a problematic SSH session try entering 'stty erase ctrl-v ctrl-?' Then hit the backspace key and see if it behaves as normal. If that works, then you have a terminal emulation problem, and need to try some other terms to find one that works for your keyboard (must be set both client AND server-side). If you think you really need to edit the keyboard mappings then the file is /etc/termcap but i strongly recommend trying a few different terminals (try vt100, linux, xterm, etc) before editing that file. Remember, they need to be set in pairs, so change the term on both sides, disconnect, reconnect with the new term, and do your tests.

Qemu audio with win2k3 guest.
Hi all, Running QEMU 0.9.0 from the ports on a FreeBSD 6.1 host box running a win2k3 guest. Everything works great except audio, i was wondering if anyone has got audio working with a win2k3 guest? Windows sees the hardware but has trouble adding drivers. Would appreciate any help.

Vinum.
Hi all, I was wondering what Vinum configurations others are using and what is a good balance between performance/redundancy? I've gone with RAID10 (2 striped plexes with 3 subdisks each. The plexes are mirrored to each other). vinum.conf: drive a device /dev/da1s1e drive b device /dev/da2s1e drive c device /dev/da3s1e drive d device /dev/da4s1e drive e device /dev/da5s1e drive f device /dev/da6s1e volume raid10 plex org striped 512k sd length 0 drive a sd length 0 drive b sd length 0 drive c plex org striped 512k sd length 0 drive d sd length 0 drive e sd length 0 drive f I havent done any profiling but it feels a little slow to me. Thought i'd talk to others to see what their using and see if i should restructure my volume.

Re: How many hosts can utilize one NAT server?

I couldn't find it on the net, although I know it's there somewhere. This would depend on the type of NAT being done, ie 1:1 static or PAT (aka overloading). If the latter, you can only support (around) 65,535 sessions or the size of a 16bit port number.
