On 01/23/2011 02:28 PM, walt wrote: Okay, I genuinely have grub2 installed and doing exactly what it's supposed to do: boot your machine using only partition LABELS, not device names/numbers... If you got through part 1 you should have all the files you need to install grub2 to your drive's boot block -- that's the part that is potentially dangerous, so practice installing to a USB thumb drive *before* you try it for real. All of my USB thumb drives were formatted FAT16 at the factory, and grub2 (being a bit of a pig) won't fit in a FAT16 partition table. The answer is to reformat the drive to FAT32 or ext2, or you can use a tool like gparted to shrink the FAT16 fs and create a new very tiny partition for ext2. Even 3MB is big enough to hold grub -- the size of the file system isn't important -- it's the partition table that's too small in FAT16. Assume you have the ext2 partition of the thumb drive mounted on /mnt/floppy, for example, and the thumb drive is /dev/sdc. For the actual install you need to be root because you will be writing to the device as well as the ext2 fs on the device. # mkdir -p /mnt/floppy/boot/grub # /home/walt/sbin/grub-install --boot-directory=/mnt/floppy/boot/ /dev/sdc That second step will write the actual grub2 boot block to the thumb drive, as well as copying lots of grub modules to /mnt/floppy/boot/grub from /home/walt/lib/grub/i386-c. All of those grub 'modules' contain the actually code that does things like print the boot menu on your screen and accept keystrokes from your keyboard, search for partition LABELs, UUIDs, display boot splash screens, play idiotic tunes, load custom fonts and fancy colors, and tons of other stuff you won't ever want if you're still sane. That should be enough to let you boot into the grub2 shell from your thumb drive, assuming you set your BIOS to allow it. Just like legacy grub, the grub2 command shell will always show you what you can type next if you hit the tab key -- and there is quite a long list. The important commands to learn are 'ls', 'search', 'probe', 'help', and 'linux'. That 'linux' command is what actually loads your kernel from the /boot partition after you have located it with the search and (possibly) the probe commands. Use the help command and the tab key whenever you don't know what to do next. You'll pick it up very quickly that way -- far faster than trying to read any of the incomplete documentation. One very clueful tool is the brand new utility 'grub-menulst2cfg' which you should find in your ~/bin directory. Running that on your existing /boot/grub/menu.lst will show you the equivalent commands for your new /boot/grub/grub.cfg file. Very neat, and isn't included in the current stable grub-1.98. Once you play with the grub2 command shell you will easily see how to use the same commands in grub.cfg because the syntax is the same. Next time I'll explain how to use GPT (GUID Partition Table) to let your kernel find and mount your root partition using its UUID without an initrd. Very nifty!

[gentoo-user] modifying iptables: how can I prevent locking me out?
Hi, I have to change rather complex iptables rules on server and I do not want to lock me out as this server is about 50 miles away. So how should I do it? I can back up the old rules by running: /etc/init.d/iptables save and it will be saved to /var/lib/iptables/rules-save (some strange format starting with number like [536:119208]) I prepared a script with new (modified) iptables-rules, which I will run in bash. But in case I screw something, how could I force netfilter to load old saved rules, if I for whatever reason do not connect to server (ssh)? Or can I load new iptables-rules for certain time, and then force netfilter to load back the old rules again? Jarry -- ___ This mailbox accepts e-mails only from selected mailing-lists!

I've discovered that I can suspend it with {CTRL-S}, but I shouldn't
have to resort to that. Using Google, I found references to
man termcap, which stated that this behaviour was controlled by
entries in /etc/termcap. Despite the fact that I have the termcap man
page on my system, I do *NOT* have /etc/termcap. Does anyone have a
sample /etc/termcap (or will ~/.termcap work?) to stop the screen

Walter,
You can always call it back up. The other window, that is. Just
Ctrl-middle-click the xterm and choose Show alternate screen.
Presto.

I haven't tried FreeNX, x2go or NeatX or any of those, but I'm using nxserver-freeedition for years and using the official NX Client to connect from remote machines (Linux and Windows). All of the features work such as session suspending and resuming. I use public key login on my machine and there was some trick to getting it working initially. (I don't remember, but if you search for my name and nxserver in this list's archives there should be a message about it somewhere.) I think that the other NX clients, such as QtNX, or things based on libnxcl, usually only work to connect into a FreeNX server and not with the official NX servers. Ideally I think the nx client version should match the nx server version for best results. I'm also using using nxclient from nomachine.org. I only tried nxserver-freeedition on an Ubuntu server where I had some trouble running FreeNX. It worked well first, but then I started getting some errors about a wrong 'bsize' or something. Ususally a few retries later I can connect, but at the moment I can't. I did not investigate this further yet because there are other servers in that LAN than I can use instead. FreeNX is now working on my new machine. First I had to emerge xterm, which was the custom command I wanted to execute. Stupid error, but a message that the command could not be found would have been nice. And then I had to change the DISPLAY_BASE in node.conf. Looks like when running multiple instances of nxclient those values have to be different. That was with Windows XP. Now I tried to connect from my Linux Desktop, and got an error about the display :1043. I set it back to the default of :1000, and it works again. ... So it looks like when runing multiple clients, their servers need to have different displays. Additionally, there is a timing problem, a workaround is to add a sleep 4 in /usr/bin/nxnode right before the xrdb starts. I found this tip somewhere on the web, noone added such a patch yet, probably because FreeNX is dead. nxclient contains a whole X server, which is really not necessary if the client machine is already running X. Ultimately if your client has X and ssh already, you just need nxproxy. Connect to server and run nxagent and have a working session (there are shell scripts to do this on platforms who have X but not nxclient, such as ARM). But you won't get any of the special features like suspending and resuming, printing, sound, etc. I never used sound or printing, although it might be nice. But suspending/resuming sessions is really cool. I often run nxclient from my Windows Notebook in the living room to run stuff on my linux desktop, and I can shut down the notebook in between if I like. Thanks for your input. I will consider nxserver-freeedition for the next time I set up this stuff. FreeNX is dead, and I read that it is also a genrally a little slower than the nomachine version. x2go looks not yet ready, but I think I'll also try it when the next version arrives and I have some spare time to paly around with.

As an example I've attached a little EL function... Can't give you a real answer, but that code looks very much like Pascal. Reminds me of a misspent youth. In 1983 I certainly wasn't a turbo user of Turbo Pascal either... ;-) Is there a definite reason for choosing C instead of something else, e.g. python? Just idle curiosity, nothing more. I'm interested in learning a bit about CUDA as an evaluation platform and the tools from NVidia are based around C. (As best I understand.) If I knew a wee bit more about m4 I'm sure I could do it with that alone. But I'd need to do actual work to learn m4, which is not likely to happen... Thanks! - Mark
Re: [gentoo-user] Adding more than one static IP

I have 4 static IP's on server machine I have one nic on my desktop. It sits behind an ADSL router-modem which has address 192.168.123.254. * My little LAN is 192.168.123.248/29. I want that to always go via the router/modem, so I give that path metric 0 * I have an HDHomerun TV tuner that pops up in the 169.254.0.0/16 block. That path also gets gets metric 0 * Default (i.e. to the internet) is metric 2 via the router * Because the default is metric 2, dialup (temporary ppp0) can take over internet access, without interfering with LAN traffic or my TV tuner.

Additionally there are often two lines added to each device saying similiar things like: Kernel driver in use: XYZ Kernel modules: XYZ and there other devices do not have similiar entries. My question is: How can I distinguish devices/entities, which do not need any driver to work and those, which need a driver but in the current setup the driver wasn't compiled in/compiled as module? Thank you very much in advance for any help! Best regards, mcc Devices that need a driver are listed as 'Kernel driver in use:' whether the driver is compiled in or not. Devices that have their driver compiled in do not have the line 'Kernel modules:' Devices that have neither line are controlled by the kernel but don't need anything from the driver section. I suppose there is the possibility that lspci could find a PCI device which hasn't had a driver selected as module or builtin and then not show anything. In this case I expect that the device wouldn't function. Hope this helps, Mark Check out http://www.kernel-seeds.org for a walkthrough of kernel configuration or dump the results of lspci -n into http://kmuto.jp/debian/hcl/ for a list of modules James Wall - -- No trees were harmed in the sending of this message.
