[9fans] how to print a program

Hello, I want to 'print' the 'page' program, i.e. put /sys/src/cmd/page/* on paper. I want different files start on new pages, with the header of every page being the file name and the page. For this the command a=`{ls} pr $a | lp -dstdout > toprint.ps is almost ok. That 'almost' is in the fact that long lines get truncated, which is highly undesirable. fmt -j could help, but it also replaces spaces and tabs by a single space, again bad. (btw. why fmt <>afile doesn't work?) So how? Can anybody help? (I mean, is there a one-liner?) Thank you! Ruda

[9fans] plan 9 virtual hosting?

I've been looking around for virtual hosting for plan 9, and I was wondering if anyone knew of anything besides what's available at freeshell/sdf? Thanks! -- John Osborne osborne6@gmail.com/jro@freeshell.org

[9fans] sharing the ndb(6) database

My new auth server is completely standalone: it uses the kfs file system and boots off its own (solid state) disk. The rest of the network, for which it performs the authentication tasks, is based on a separate file server node. The auth server also runs dhcpd, tftpd, and a dns server. As such, its /lib/ndb/local file contains a description of the whole network, as well as dns root stuff. Now, the rest of the network also needs much of the same info as the auth server, in order to easily call each computer by sysname, etc.. This means that when a new node is added to the Plan 9

parallels and 9vx crash

Hi All, I have this problem from the beginning, when I run Parallels install of Plan9 (or any other VM) and 9vx, my OSX 10.6.4 crashes. here are the details if at all anything makes sense, though it looks like parallels problem. ========================= Interval Since Last Panic Report: 809258 sec Panics Since Last Report: 5 Anonymous UUID: DF63D9B7-57A2-4654-984C- BEDEA5EBE6C2 Fri Sep 3 21:41:01 2010 panic(cpu 1 caller 0xffffff80002cef74): Kernel trap at 0xffffff8059bd747d, type 13=general protection, registers: CR0: 0x000000008001003b, CR2: 0x0

[9fans] Sheevaplug - USB working? Just checking

Just checking before I buy something; do the host-side USB ports work on the Sheevaplug? That's the ports you plug USB devices into, not the port you connect to a PC. I can never remember what the proper term is.

[9fans] Plan 9 on the Acer Aspire One

I tried installing Plan 9 on the Acer Aspire One, after having checked that I can boot into it via PXE. I used erik's 9atom2.iso. However, without having touched the mbr, when trying to boot off the disk, it simply hung after BIOS POST. Then, having tried disk/mbr -m /386/mbr /dev/sdD0/data (yes, disk is at sdD0, and there are not enough BIOS options to change that) I get: "Press a key to reboot" after BIOS POST. So, there's not even an attempt to find or deal with the loader yet - it seems purely a problem of the MBR? Is there something that can be done here? If I PXE

[9fans] resizing desktops uncer vmware vs. parallels

For ages I've run diskless terminals under Parallels, and aux/vga would quite cheerfully resize the Parallels window to match anything I told it. Recently I had to migrate from Parallels to Fusion. Resizing doesn't work any more. Furthermore, I'm buggered if I can programmatically figure out what combinations of screen size+depth will work in Fusion without making the terminal instance panic. The list archives and the wiki are absent of advice.

kw I²C

I'm working on a audio driver for kw (openrd) as a warmup for other more useful drivers (do something easy before something hard), and I've come to the point where to do anything more requires talking to the audio codec. According to various linux patches, this is done over I²C. Has anyone done anything with I²C, is it used for anything else? The kirkwood functional specification does not mention it (at least so far as I can see in the copy I have). Elseways I'll scrounge around some more. Thoughts? tristan -- All original matter is hereby placed immediately under the public d

[9fans] native lbl, long text in troff, bold italics in eqn

Hello, I have basically 3 questions: 1) is there a native lbl (for symbolic labels in text documents), or do I have to grab the unix tarball and somehow compile that? (How? Using APE? Never tried that before...) 2) I heard and read that the 'ms' troff macros are not suitable for longer documents (I want to write my PhD thesis), as opposed supposedly to the 'me' macros (which, however are not in plan9, I believe). Can anybody give me their opinion? 3) Although eqn produces worse result than TeX, I like the way formulae are input, and thus have used it. Sometimes I need bold i

[9fans] python read problem

I've noticed some behaviors I can't explain with python and plan9. I am using contrib/installed bichued/python. Trying to read from a serial port I would suspect I would have to use f.read() if I want to be able to catch a specific string where there is no newline. For instance: When my firewall is finished booting it end with this output: Type help or '?' for a list of available commands. firewall> "firewall>" being the command prompt. I would expect to see the same from: import sys f = open("/dev/eia0","r") while (True): sys.stdout.write(f.read(1)) Yet this onl

[9fans] source header question

[9fans] TCP port hung up

I halted aquarela(1) with a ^D sequence, and made sure all processes were gone. ps(1) lists no processes on the server that could possibly be using port 445 (the port aquarela listens on for the CIFS service). And yet, netstat -n showed that TCP port 445 was still in LISTEN state. Naturally, I ran echo hangup > /net/tcp/31/ctl to relinquish the port. Now it's in CLOSED state: tcp 31 bootes Closed 445 0 :: but the port is still unusable (pre-occupied - aquarela(1) is not able to open it). Short of rebooting the CPU server, is there some way to reg

[9fans] tcp resequence queues

as it turns out, limiting the number of packets in the resequence queue does catch a few ill behaved connections that are not sending tinygrams. in this case, smtp: Thu Aug 5 20:40:59: resequence queue > packets: 61 60; 81058 bytes Thu Aug 5 20:40:59: reseq x.x.x.x.54772 -> 12.51.113.7.25 Sun Aug 8 16:57:54: resequence queue > packets: 46 45; 34000 bytes Sun Aug 8 16:57:54: reseq y.y.y.y.1202 -> 12.51.113.7.25 (window scaling accounts for the different packet limits.) - erik

[9fans] ethernet booting

I'm booting over ethernet, using the basic 9load (not 9pxeload). However, in /lib/ndb/local on my CPU server (where it downloads 9load), I can only specify bootf=/386/9load that is, I can't specify an INI file. I know the 9pxeload loader looks in /cfg/pxe/<macaddr> to grab INI details; what can be done for basic 9load? Is there some specification? Can I get it to download the INI file as well, some how? Thanks, ak
