[9fans] ktrans on p9p
Dear all, I've found ktrans to be extremely useful in 9vx (thanks, Kenji), and I'm wondering now whether it would be possible to use it with plan9port (on Linux). Mainly I would want this for acme -- would it make sense to modify p9p acme to include ktrans within it? Or is there a better approach? Any suggestions on how to go about this would be much appreciated. Also, in case it is of use to anyone else, I modified ktrans to support ancient/polytonic Greek, using betacode input: http://bitbucket.org/alexlee/ktrans/ And here is a ttf2subf'd version of DejaVu Sans, for better Greek glyph coverage: http://dl.dropbox.com/u/1734204/djsans.tar.gz Alex

I am going to try that this weekend, and if he started to patch some code, I would appreciate the head start. This doesn't give much of an answer to Jack's question, but in case it is of use: I recently tried compiling a 9xen kernel, because I wanted to run Plan 9 with Debian Lenny, which has a prepackaged Xen 3.2.1 system. The kernel did not compile against the most recent sources. There was a mismatch in the function prototype of cpuid in pc/fns.h and xen3/fns.h that caused compilation to fail: void cpuid(int, ulong regs[]) versus void cpuid(char*, int*, int*). I had an older install CD image, from around Aug 2008, so tried again using sources from that. This time compilation worked, but Xen rejected the kernel and gave some sort of version mismatch error (which I think is the same error it gave when I tried booting Richard's precompiled 3.0.2–4 kernels). Sorry for the lack of detail; I don't have Xen 3.2.1 running anymore, so I can't run it again to see the exact message. If I find time I'll try it again. I'd love to hear if anyone else has made more progress. Unfortunately, like Andreas, I'm lacking in the time and know-how to contribute much to this. In the end I just installed the Xen system from Etch (oldstable), which uses Xen 3.0.3. Richard's kernels boot and have been working great (thanks, Ron and Richard, for your work on this!).

Does this mean Plan 9 is not compatible with Xen 3.2, or does it just need a recompile or some other quick fix? It's compatible with Xen 3.0.x for some x.

A useful thing to do is cat /dev/time and see how it changes. The time from lguest is simple: you read a 64-bit # which is time. It's just like Xen that way. Also, try this to test another issue: date sleep 60 date Two things: should take 60 seconds by the watch and the two dates should report 60 seconds apart. Do they? ron I've doublechecked the timezone setting, and it appears to be correct. The 'date' test seems to work fine: # date sleep 60 date Thu Aug 28 15:52:19 CDT 2008 Thu Aug 28 15:53:19 CDT 2008 Within a second of one another, I ran: lguest: cat /dev/time 1219956674 1219956674748050432 12199566747480504324294967296 host: date +%s 1219943774 So lguest is 12900 seconds ahead (= 215 minutes, = 3 hrs 35 minutes).

Best++ John Hi again, A couple of updates: I'm getting the same cron messages and time problems that John is seeing. I've made sure that timesync isn't running. My lguest time is about 3.5 hours ahead of host time. As for the load issue: The full cpu usage that I was seeing earlier actually stops after a several minutes. After booting, ^T^Tp shows genrandom as Running. Several minutes later the cpu usage drops to near idle, and genrandom goes to Wakeme. Then every now and then (I'm not sure if anything in particular triggers it, or if just randomly happens) I see the cpu usage jump again, and I can see that genrandom is once again Running. Then after several minutes it stops again. When genrandom is running, stats shows a load of around 3000. Otherwise, load is always around 2000. The problem looks similar to this: http://9fans.net/archive/2006/03/588 -- except that the lguest instance works fine while genrandom is running. Is this genrandom behavior anything out of the ordinary? Alex -- Alex Lee [EMAIL PROTECTED]
[9fans] lguest on 2.6.25
Hi all, I'd like to set up a cpu/auth/file server for my home network. I already have a laptop server running Ubuntu 8.04, so the idea is to also get Plan 9 running on it, via lguest. It's mostly working, but I'm encountering a few problems. Here's what I've done so far (maybe it's excessive list every single step, but just in case...): 1. Grab relevant files. - Download 9lguestcpu.2.6.25.elf and RUNLGUEST from Ron's contrib directory - Get thx9.img out http://9grid.net/rminnich/src/lguest/thnx9.bz2 - Download the 2.6.25 kernel: linux-2.6.25.tar.bz2 (dated 2008-04-17; I tried the latest version, 2.6.25.16, but encountered the same problems that were reported in http://9fans.net/archive/2008/07/690) 2. Compile and install kernel - I start with the stock 2.6.25 kernel. I then copy in my current config (Ubuntu 2.6.24-19-generic), run 'make oldconfig', then answer the config prompts with mostly the defaults. - Then I configure the LGUEST, LGUEST_LGUEST, VIRTIO, etc. config entries as per the lguest.txt documentation. - Then I compile (here the debian way, with 'make-kpkg kernel_image kernel_headers'). - I also run 'make' in Documentation/lguest to get my 'lguest' binary. 3. Prepare host machine - Install the new kernel on the host machine and reboot. - modprobe lg syscall_vector=64 - iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE - echo 1 /proc/sys/net/ipv4/ip_forward 4. Run Plan 9 in lguest - I modified RUNLGUEST so that the command is: ./lguest 256 9lguestcpu.2.6.25.elf --block=thx9.img --tunnet=192.168.19.1 'venti=#S/sd00/arenas;bootdisk=local!#S/sd00/fossil;bootargs=local!#S/sd00/fossil' - sudo ./RUNLGUEST Eventually it prompts for the filesystem, and I pick the default. Here is the output from that point onwards: root is from (tcp, il, local)[local!#S/sd00/fossil]: disk is #S/sd00/fossil AUTHENTICATE ... time... GET VENTI ENV! #S/sd00/arenas IN THERE AND nf is 1 F 0 is #S/sd00/arenas venti...configloopbackk!

So I modified /lib/ndb/local so that the dns entry pointed to my router (192.168.1.1), and then I ran the following: % ip/ipconfig -g 192.168.19.1 ether /net/ether0 192.168.19.2 255.255.255.0 % ndb/dns -r And then I can resolve names and ping out. So far, so good, but there are three problems that I'm still trying to figure out: 1. How can I avoid having to manually configure networking each time I boot? 2. I can ping from the host machine to the lguest interface (192.168.19.2), but when I try to connect with drawterm the connection is refused. 3. lguest always runs at full CPU. How can I figure out why this is happening? (I don't feel comfortable running lguest for more than a few minutes at a time -- the laptop gets pretty hot.) Any advice or pointers on these issues would be greatly appreciated. Thanks! Alex -- Alex Lee [EMAIL PROTECTED]
