Upgrading kernel on a system that won't boot
I have a system running etch. I believe it has this kernel installed: linux-image-2.6.18-5-k7 2.6.18.dfsg.1-13etch2 The motherboard failed a few days ago, and I've just got a new motherboard and cpu.

Grub finds the kernel and it starts fine, but it has trouble when trying to mount the real root filesystem. This filesystem is raid 1 (md), and the kernel can't find either device. The hard drives are SATA, and the BIOS lets me configure them as Legacy ATA, RAID or AHCI. I've tried Legacy ATA and AHCI, and neither works. A recent live CD is able to see the drives without any trouble, so I suspect I need a newer kernel. Finally my question: can someone explain how to boot from a live CD and upgrade the kernel I have installed? Do I just mount the various filesystems into a subtree, chroot to the root of that subtree, adjust sources.list, and do the upgrade? Secondary question: Will the dependencies allow this without essentially upgrading to lenny? Or is there an etch backport of a more recent kernel? Or maybe I should just compile one from source for now? Or is there an alternative, manual way to drop a new pre-compiled kernel onto the existing system?

recovering /var, especially /var/lib/dpkg
I had a laptop stolen and shortly afterwards the two hard drives on a server both failed. Unfortunately, those drives contained the backups of my laptop, and I wasn't able to recover my backup of /var. So on my new laptop I have restored everything except /var, and the question is whether it will be possible to recover the essential parts of /var. Luckily, before running each backup I save the output of dpkg -l in /root, so I have a list of all installed packages and what version is installed. Is it possible to use this information to recreate the data dpkg needs to operate? What exactly is needed? [I realize that I could just reinstall all the packages from scratch. But that would entail answering lots of debconf questions, and doing a lot of merging of conffiles since many packages will have been updated since the laptop was lost. (It was a while ago and I follow testing.) So I'm hoping to avoid a reinstall.] After getting dpkg working, are there any suggestions about how to restore the other parts of /var?

My understanding is that in the file system, hard links are stored by referencing the inode. It is only tar that needs to convert this to a textual form for storage in the tar file. By the way, the files I had problems unpacking were standard Debian executables in /usr/bin and /bin. So I maintain that tar can't unpack hard links properly.

help with IP Masquerading, 2.4 kernel
My main machine, scratchy, is connected to the net using PPPOE (PPP over ethernet) over DSL. I have another machine, cheddar, connected to a second ethernet card on scratchy with an ethernet crossover cable. I am trying to using netfilter (iptables) to masquerade cheddar behind scratchy, and it is almost working: pings and DNS lookups work fine, with no packets dropped and no errors. telnet and ssh work as well, until I try to transfer a lot of data at once (e.g. a screenful, such as appears when you bring up a man page), at which point the connection freezes. wget freezes immediately. But netstat -i doesn't show any errors or dropped packets, and there is nothing in the log files of any of the three machines involved. Connections between cheddar and scratchy and between scratchy and the outside world work perfectly. Any suggestions where to look further? Here's are some settings: cheddar# ifconfig eth0 Link encap:Ethernet HWaddr 00:01:03:85:AC:D8 inet addr:192.168.0.2 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:22 errors:0 dropped:0 overruns:0 frame:0 TX packets:28 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 Interrupt:11 Base address:0xd400 loLink encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16144 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 cheddar# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric RefUse Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 00 eth0 0.0.0.0 192.168.0.1 0.0.0.0 UG0 00 eth0 scratchy# ifconfig eth0 Link encap:Ethernet HWaddr 00:80:C8:B9:FD:24 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:180469 errors:1 dropped:0 overruns:0 frame:16190 TX packets:173454 errors:87 dropped:0 overruns:0 carrier:153 collisions:1241 txqueuelen:100 RX bytes:113137907 (107.8 Mb) TX bytes:19757452 (18.8 Mb) Interrupt:3 Base address:0x300 eth1 Link encap:Ethernet HWaddr 00:E0:98:03:CF:B0 inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:28329 errors:0 dropped:0 overruns:0 frame:0 TX packets:29667 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:1911832 (1.8 Mb) TX bytes:42401143 (40.4 Mb) Interrupt:9 Base address:0x320 loLink encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16144 Metric:1 RX packets:26861 errors:0 dropped:0 overruns:0 frame:0 TX packets:26861 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:13163203 (12.5 Mb) TX bytes:13163203 (12.5 Mb) ppp0 Link encap:Point-to-Point Protocol inet addr:129.100.240.47 P-t-P:129.100.2.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1 RX packets:84071 errors:0 dropped:0 overruns:0 frame:0 TX packets:71905 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:93703135 (89.3 Mb) TX bytes:6373070 (6.0 Mb) scratchy# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric RefUse Iface 129.100.2.1 0.0.0.0 255.255.255.255 UH0 00 ppp0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 00 eth1 0.0.0.0 129.100.2.1 0.0.0.0 UG0 00 ppp0 scratchy# iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- 192.168.0.0/24 anywhere Chain OUTPUT (policy ACCEPT) target prot opt source destination Thanks for any help anyone can provide!

More important are: the time required to download new versions when I dist-upgrade; the time required to unpack and install these; the additional time taken to perform a backup; the possibility of needing an extra CD to backup onto (my system is close to overflowing a CD); and, if my system grows enough, the time required to install a new, larger hard drive and transfer the system to it.

Why do you think it's using 50M? Sure -you- aren't using it? I'm a bit confused about memory usage on my system, where I am running the 2.4.0-test12 kernel. Similar things seem to be happening with test5, the only other kernel I've used recently. In addition to the 3.7M difference between the memory I have installed (128M) and the MemTotal value, there is also a lot of memory being used that isn't allocated to any processes that I can find. For example, below is the output of top which shows all the processes I had running at that time (I had killed most things). Notice that mem used + swap used - buff - cached is about 16M, even though if you add up the sizes of the processes you get only 8M or so. The output of free confirms this. Is this normal? What is using this 8M? The kernel already has 3.7M reserved! And when I when I run the program gmemusage, it says that linux is using between 4 and 8M. Anyone have any explanations?

As another poster said, you can change the default fixed font.
But the question is, where did the old fixed font go? Can it be
included in the distribution? Or is there some other place to

BTW, it

Computer Modern -- by default (others if you so choose).
I think he was referring to the .tex source files. They do look funny
with unsymmetrical quotes.
While we are talking about fonts, does anyone know why the italic
version of the default fixed font looks to bad? (I'm referring to
the default italic font that shows up in emacs, for example.) It
has very blotchy vertical lines.

files appear corrupt, but aren't; kernel bug?
Over the past few hours, my potato machine has been behaving very strangely. Many of the files on my hard drive or which I read from cdrom have minor errors.

Every file I read that had bad bytes, consistently had the same bytes bad until the problem went away. Then the bytes were back to their correct values. I don't think this is a caching issue, since I tested this on lots of very large files, larger than the ram I have available. And I have proof that I wasn't just imagining things: while there were problems I copied a bad file to another file name. Now the original is file, but the copy is still bad. Very strange. Does anyone have any other ideas? Dan -- Dan Christensen [EMAIL PROTECTED]
Re: Upgrading pcmcia-* breaks ppp
[EMAIL PROTECTED] writes: After buying a pcmcia nic I thought that upgrading the pcmcia-* packages and recompiling the pcmcia modules would be a good idea. [...] this broke my ppp setup somehow. I have a 56K pcmcia modem, running as ttyS2 (pppd uses /dev/modem which is a symlink pointing to /dev/ttyS2). Now, whenever I fire up pppd I get: Jan 15 19:16:30 sirius pppd[352]: pppd 2.3.5 started by lehman, uid 1001 Jan 15 19:16:30 sirius pppd[352]: tcgetattr: Input/output error(5) Jan 15 19:16:31 sirius pppd[352]: Exit. ...just as if the modem wasn't inserted at all. [...] And setserial says: I found two solutions to this problem. The easiest is to remove the setserial package. Doing this solved my problems immediately, so unless you need setserial for some reason, it seems like a good thing for you to try. A more awkward fix that I stumbled upon by trial and error was to run the following script near the end of the boot process, after cardmgr starts and sees the card: #!/bin/sh # This seems to make my pcmcia modem work. Didn't need to do this # before upgrading from slink to potato. This assumes that the # modem will be in slot 0, the top slot. echo Setting /dev/ttyS1 irq to 7; ejecting cards; inserting cards. setserial /dev/ttyS1 irq 7 sleep 1 cardctl eject 0 sleep 3 cardctl insert 0 Of course, the irq you choose may need to be different. Hope this helps. Dan -- Dan Christensen [EMAIL PROTECTED]

bad alternatives symlinks after potato upgrade
I just upgraded my mostly stock slink machine to potato with apt-get update; apt-get dist-upgrade. Now I have both /usr/man and /usr/share/man on my system, and neither is a symlink to the other. A quick glance showed no files in common between the two directories, and they both contain around 7.5M. man foo works for foo's in either directory. But the alternatives system is messed up, with symlinks pointing to the wrong place. An example is /etc/alternatives/editor.1.gz, which points to /usr/man/man1/elvis.1.gz, which does not exist. However, /usr/share/man/man1/elvis.1.gz does exist. What happened? Would manually changing all the bad symlinks in /etc/alternatives to point to the right place be the correct fix? Is there an automatic way to do this? Thanks for any suggestions. Dan -- Dan Christensen [EMAIL PROTECTED]
Re: questions about slink to potato upgrade
Graham Williams [EMAIL PROTECTED] writes: I went that path also (dist-upgrade to get potato) and had some of the same problems. The most serious for me was that my pcmcia modem card stopped working somewhere along the way. I also have had this problem. One thing that makes my modem work again is to type: setserial /dev/ttyS1 irq 0 (You will need to replace the device with the correct one for your modem.) irq 0 means to not use interrupts, and instead use a slower polling method. So this isn't a long term fix. My modem does sometimes work with real irq's, but usually does not. Does anyone have any other suggestions? Dan

'cardctl resume' twice kills slink
I have a Transmonde Vivante laptop with a PCMCIA modem running Debian 2.1. I recompiled kernel 2.0.36 to use apm, and recompiled the kernel modules as well. For the most part, my modem is fine. If I type 'cardctl suspend', all is well. However, if I then type % cardctl resume; cardctl resume then my machine crashes. (I think cardctl forks to the background, so this is like running two copies at about the same time.) The crashes come in different flavors, but almost always happen. Occasionally I get what is probably the correct behavior, namely an error message ioctl(): Device or resource busy. But most of the time I get a crash. Usually thousands of lines of numbers scroll by (if I'm logged into a virtual terminal when running cardctl), including things like Call Trace: ... and Code: ... and Aiee, killing interrupt handler. Then the machine freezes, and won't respond to anything but the power off switch. Once I managed to get syslog to capture a bit of info. In my /var/log/syslog is May 8 19:36:03 scratchy kernel: out during reset May 8 19:36:03 scratchy kernel: cs: socket 0 timed out during reset (This is followed by 14 null characters, and then a fragment of the directory listing of /dev. This probably indicates some filesystem corruption from the crash.) In case you are wondering how I discovered this, it comes up because of the way the apmd package is set-up. In /etc/apm/resume.d/pcmcia is a script which runs 'cardctl resume' if a file /etc/pcmcia/apm.opts exists and contains the line APM=suspend. It occured to me that I should suspend and resume my cards when suspending and resuming my machine, so I created a file apm.opts containing that line. This is when the crashes started. I think what is happening is that apmd is running the equivalent of 'cardctl resume' already. Thus I think that those scripts should be removed from the distribution, as they cause serious problems when used. Please correct me if I am misunderstanding something. The more fundamental problem is with cardctl, which should never cause the machine to crash. Could people test this with their machine? I recommend unmounting unused filesystems and typing sync before doing so. Anyways, the workaround is simply to not run two copies of 'cardctl resume' at the same time, but I thought I would report this to the list in the hopes that the root of the problem is fixed. Comments or requests for further information, to the list or directly to me, are welcome. Should I submit this to the bug-tracking system? I've never done this -- is it self-explanatory?

Re: Exim and fetchmail

I had this problem too, and fixed it by adding localhost to my local_domains setting in /etc/exim.conf: local_domains = scratchy:localhost This is the variable which specifies which hostnames should be treated as aliases for the local host. (scratchy is the name of my machine.) I regard this as a bug in the installation procedure. Either fetchmail should deliver to user (without the @localhost) or exim should be configured by default to accept such mail. Dan -- Dan Christensen [EMAIL PROTECTED]
what are the various i486 directories for?
I'm running slink on a Celeron 300 laptop. Looking around on my disk I discovered a few directories whose purpose I don't understand. Could someone explain what the following are for? /usr/i486-linuxchecker /usr/i486-linuxlibc1 /usr/lib/gcc-lib/i486-linux /usr/lib/gcc-lib/i486-linuxchecker The reason that I'm asking is that I have a Celeron chip, so I was surprised to see 486 stuff.
