Re: not able to output anything to /dev/ttyv8?
Along those same lines, I'd like to output iftop to ttyv0 (main console) with login across serial and/or another tty. I get rate limit errors of some sort when I edit /etc/ttys. What method should I use to ouput an application such as iftop to a tty?

I start to thinking of piping result to a tty because the box running this app is not far away and I just think it's fun and looking nice to have it poping up progress :) As you said, this is not very very necessary, it's mostly for fun and a little bit easier for me -- Zhang Weiwu Real Softservice http://www.realss.com +86 592 2091112 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to " [EMAIL PROTECTED]" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

It doesn't make me nervous when I have to RTFM as I did many times and, now I am RTFMing, but, I got a feeling I am entering a "maze" filled with things I don't know: termcap, bound rate... Anyway this is how I did it after RTFM, stupid but works: 1) go to /etc/gettytab and add this: W|Wd|Wd console:\ :ht:np:al=root:sp#9600: 2) run /usr/libexec/getty Wd ttyv8 3) now you can run your application and redirect to ttyv8 # app > /dev/ttyv8 This is ugly, but it works. I'd very like to see better solutions. If you don't add that line to /etc/gettytab, run /usr/libexec/getty Pc ttyv8 will get you a ttyv8 console that you can redirect output to, but that console seems ignore carrier return / line feed, making the output difficult to read. P.S. I'd very much like the console ttyv8 can be at a speed of 9600, now it output anything almost instantly, so sometimes I cannot watch the output scroll with my eyes (by the special nature of the application I am running, glance over the output of my application when I am free can help me find a lot of useful information). The application produce less then 20MB of data, so 9600 kbps is a good measure to control the pace of output. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
