[9fans] first questions from a lurker
Hello All. I've been a lurker on 9fans for many years. Today I finally did an install - +9atom.iso.bz2 into a virtual box VM. The VM is NAT'ed to a corporate network and I can ping by IP address with no problem. First questions. 0. How to see my IP address? Cat a file in /net/... somewhere? 1. How to change the hostname - just edit /rc/bin/termrc and choose whatever I want to echo into /dev/sysname? Will that get reflected back out to the corporate net via DHCP? 2. How to use DHCP to get to the corporate DNS servers? (This worked pretty much OOTB on the labs dist, but I think that 9atom will be the better match for the work we want to do.) Right now all hostname lookups (via ping) fail. Unrelated: 3. I would like to generate a PDF (or even .PS file) of Volume 1 of the manual. What's in the dist has dates from over 10 years ago. I tried running 'mk print.out' in the manual directory (as glenda) but got an error. (Erik - can you do that automatically as part of your build process? :-) So. How can I produce such a file suitable for duplex printing? (Bonus points if the intro(N) page of each section comes out first. :-) Please go easy on the Plan 9 newbie who has to unlearn 30+ years of Unix habits. Thanks! Arnold

And of course, I forgot another question: 4. How to do the moral equivalent of shutdown -h now? Thanks, Arnold - arn...@skeeve.com wrote: Hello All. I've been a lurker on 9fans for many years.

Right now all hostname lookups (via ping) fail. If you edit /rc/bin/termrc and uncomment the lines about ip/ipconfig then reboot it should come up networked, then try ndb/dnsquery to test your connectivity Bonus answer: to shutdown I'd do fshalt wait a bit, then close the VM Pete

Welcome to the party. On Mar 10, 2014, at 10:41 , arn...@skeeve.com wrote: 0. How to see my IP address? Cat a file in /net/... somewhere? As Charles said, 'cat /net/ipselftab'. You most likely want the lines with 'u' in the flags filed (third column), which will most likely include just the loopback address and your real address. 1. How to change the hostname - just edit /rc/bin/termrc and choose whatever I want to echo into /dev/sysname? Will that get reflected back out to the corporate net via DHCP? You could do that. The right way to do it is make your ndb database in /lib/ndb map your ip address to the sysname you want. Take a look at the examples in there and ndb(6) and see if that gets you what you're after. I'm not sure what your second sentence means. DHCP clients don't broadcast changes out. If you want that server to advertise things, you'll have to look there. 2. How to use DHCP to get to the corporate DNS servers? (This worked pretty much OOTB on the labs dist, but I think that 9atom will be the better match for the work we want to do.) Right now all hostname lookups (via ping) fail. I'm not sure why this would behave differently. Check if the local dns resolver is running; 'ps | grep dns' and 'ls /srv/dns' should both give positive results. If either one doesn't, it's not running; rm any stale /srv/dns and re-start it with 'ndb/dns -r'. I don't know that VBox's NAT will do anything helpful with the dhcp requests, though. 3. I would like to generate a PDF (or even .PS file) of Volume 1 of the manual. What's in the dist has dates from over 10 years ago. I tried running 'mk print.out' in the manual directory (as glenda) but got an error. (Erik - can you do that automatically as part of your build process? :-) So. How can I produce such a file suitable for duplex printing? (Bonus points if the intro(N) page of each section comes out first. :-) What error did you get? I just tried that on my (slightly out-of-date) 9atom installation (as myself) and it worked fine. The resulting print.out is troff output; lp can give you PostScript from that. You could also buy a lovely bound copy of both volumes from Vita Nuova. :-) Hard copy is still very nice from time to time. 4. How to do the moral equivalent of shutdown -h now? 'fshalt -h'. I'm not confident the -h part will do much in Virtual Box. Have fun. signature.asc Description: Message signed with OpenPGP using GPGMail

Right now all hostname lookups (via ping) fail. i hope this isn't too redundant. i have a little different approach ip/ipconfig will configure your machine via dhcp. to get name lookup you'll need to run ndb/cs ndb/dns -r on the man pages, i've submitted/applied a patch that should fix the ptx1.c build issue so the outfile should be generated now. i'll work on automaticly generating the manual. correctly. :-) - erik

(This worked pretty much OOTB on the labs dist, but I think that 9atom will be the better match for the work we want to do.) Right now all hostname lookups (via ping) fail. Others have answered what to do within plan9. On the virtualbox side you need to attach to 'bridged adapter' instead of NAT. Pick the right name (which is really the interface name on the host) -- wi-fi (airport) for instacnce if you are on a MBP. I think the default adapter type should work (Intel pro/1000 MT desktop). You may also have to tell the dhcp server about mac address etc. depending on how it is set up.

Pardon my not replying individually - thanks all of you for the answers! I'm looking forward to climbing this learning curve. :-) Arnold
[9fans] About plan9.ini
I've Plan9 on sdCO and sometimes want to boot from sdE0 (CFlash on ide) or from a usb key. The other devices boots but it seems that the used plan9.ini is always from sdC0. Probably something wrong on the CF/key devs I built. But, just to be sure, shouldn't always be used the plan9.ini from the boot device ? Thanks in advance adriano

Re: [9fans] About plan9.ini
according to the atmel docs, it's interrupt in, bulk out. does this make sense? http://www.atmel.com/Images/doc4322.pdf. - erik

What about Lab's 9load or 9Load on old 9Atom distros ? with 9load, you've got no options. 9load is just working against the machine. - erik
