3.5. ***Can I access BSD FFS, SysV UFS, Mac, Amiga, etc filesystems?
I'm told that there is a primitive, alpha test read-only Amiga
filesystem on sunsite.unc.edu in /pub/Linux/patches/amigaffs.tar.Z.
More information is in affs-readme in the tarfile.
Recent kernels contain support for the UFS filesystem used by System
V, Coherent and Xenix.
There is alpha kernel support, readonly for the moment, for the 4.2BSD
UFS, on sunsite.unc.edu in /pub/Linux/ALPHA/ufs.
There is a set of user-level programs that provides read-only access
to the Macintosh hierarchical filing system (HFS). It is available on
sunsite.unc.edu in /pub/Linux/utils/disk-management/hfs0_36.tgz. This
is being turned into a kernel module, which is available on sunsite.
A suite of programs called Samba provide support for Windows for
Workgroups networked filesystems (provided it's configured to use
TCP/IP). Information is available at
http://lake.canberra.edu.au/samba/samba.html. There is alpha kernel
support for mounting such filesystems, on sunsite.unc.edu in
/pub/Linux/ALPHA/smbfs.
There is no support for the rest of those yet; I have not heard of any
recent work on providing some.

9. Frequently encountered error messages.
9.1. Unknown terminal type linux and similar.
In an early 1.3.x kernel the default console terminal type has changed
from console to linux. You must edit /etc/termcap to change the line
reading:
console|con80x25:\
to
linux|console|con80x25:\
(there may be an additional dumb in there -- if so it should be
removed.)
In order to get the editor to work you may need say TERM=console (for
bash and ksh) or setenv TERM console (csh, tcsh) first.
Some programs use /usr/lib/terminfo instead of /etc/termcap. For
these programs you should upgrade your terminfo, which is part of
ncurses.
9.2. During linking I get Undefined symbol _mcount
This is usually due to a bad interaction between a brokenness in SLS
and the C library release notes. Your libc.a has been replaced by the
profiling library. You should remove libc.a, libg.a and libc_p.a and
once again install the new libraries (following the release notes, of
course).
9.3. lp1 on fire
This is a joke/traditional error message indicating that some sort of
error is being reported by your printer, but that the error status
isn't a valid one. It may be that you have some kind of I/O or IRQ
conflict - check your cards' settings. Some people report that they
get this message when their printer is switched off. Hopefully it
isn't really on fire ...
In newer kernels this message reads lp1 reported invalid error status
(on fire, eh?).
9.4. INET: Warning: old style ioctl(IP_SET_DEV) called!
You are trying to use the old network configuration utilities; the new
ones can be found on ftp.linux.org.uk in
/pub/linux/Networking/PROGRAMS/NetTools (source only, I'm afraid).
Note that they cannot be used just like the old-style programs; see
the NET-2 HOWTO for instructions on how to set up networking
correctly.
9.5. ld: unrecognized option '-m486'
You have an old version of ld. Install a newer binutils package --
this will contain an updated ld. Look on tsx-11.mit.edu in
/pub/linux/packages/GCC for binutils-2.6.0.2.bin.tar.gz.
9.6. GCC says Internal compiler error.
If the fault is repeatable (ie, it always happens at the same place in
the same file -- even after rebooting and trying again, using a stable
kernel) you have discovered a bug in GCC. See the GCC Info
documentation (type Control-h i in Emacs, and select GCC from the
menu) for details on how to report this -- make sure you have the
latest version though.
Note that this is probably not a Linux-specific problem; unless you
were compiling a program many other Linux users also compile you
should not post your bug report to any of the comp.os.linux groups.
If the problem is not repeatable you are very probably experiencing
memory corruption -- see Q9.7 `make says Error 139'.
9.7. make says Error 139
Your compiler driver (gcc) dumped core. You probably have a
corrupted, buggy or old version of GCC -- get the latest release.
Alternatively you may be running out of swap space -- see Q6.8 `My
machine runs very slowly when I run GCC / X / ...' for more info.
If this doesn't fix the problem you are probably having problems with
memory or disk corruption. Check that the clock rate, wait states and
refresh timing for your SIMMs and cache are correct (hardware manuals
are sometimes wrong, too). If so you may have some dodgy SIMMs or a
faulty motherboard or hard disk or controller.
Linux, like any Unix, is a very good memory tester -- much better than
DOS-based memory test programs.
Reportedly some clone x87 maths coprocessors can cause problems; try
compiling a kernel with maths emulation [Q7.6 `How do I
upgrade/recompile my kernel ?']; you may need to use the no387 kernel
command line flag on the LILO prompt to force the kernel to use it, or
it may be able to work and still use the 387, with the maths emulation
compiled in but mainly unused.
Much more information about this problem is available on the WWW at
http://einstein.et.tudelft.nl/~wolff/sig11
<
http://einstein.et.tudelft.nl/~wolff/sig11>
9.8. shell-init: permission denied when I log in.
Your root directory and all the directories up to your home directory
must be readable and executable by everybody. See the manpage for
chmod or a book on Unix for how to fix the problem.
9.9. No utmp entry. You must exec ... when I log in.
Your /var/run/utmp is screwed up. You should have
> /var/run/utmp
in your /etc/rc.local or /etc/rc.d/*. See Q6.11 `I have screwed up my
system and can't log in to fix it.' for how to be able to do this.
Note that utmp may also be found in /var/adm/utmp or /etc/utmp on some
older systems.
9.10. Warning -- bdflush not running.
Modern kernels use a better strategy for writing cached disk blocks.
In addition to the kernel changes, this involves replacing the old
update program which used to write everything every 30 seconds with a
more subtle daemon (actually a pair), known as bdflush.
Get bdflush-n.n.tar.gz from the same place as the kernel source code
(Q7.6 `How do I upgrade/recompile my kernel ?') and compile and
install it; it should be started before the usual boot-time filesystem
checks. It will work fine with older kernels as well, so there's no
need to keep the old update around.
9.11. Warning: obsolete routing request made.
This is nothing to worry about; it just means that the version of
route you have is a little out of date compared to the kernel. You
can make the message go away by getting a new version of route from
the same place as the kernel source code (Q7.6 `How do I
upgrade/recompile my kernel ?').
9.12. EXT2-fs: warning: mounting unchecked filesystem.
You need to run e2fsck (or fsck -t ext2 if you have the fsck front-end
program) with the -a option to get it to clear the `dirty' flag, and
then cleanly unmount the partition during each shutdown.
The easiest way to do this is to get the latest fsck, umount and
shutdown commands, available in Rik Faith's util-linux package (Q2.5
`Where can I get Linux material by FTP?'). You have to make sure that
your /etc/rc* scripts use them correctly.
NB: don't try to check a filesystem that's mounted read-write -- this
includes the root partition if you don't see
VFS: mounted root ... read-only
at boot time. You must arrange to mount the root filesystem readonly
to start with, check it if necessary, and then remount it read-write.
Read the documentation that comes with util-linux to find out how to
do this.
Note that you need to specify the -n option to mount to get it not to
try to update /etc/mtab, since the root filesystem is still read-only
and this will otherwise cause it to fail!
9.13. EXT2-fs warning: maximal count reached.
This message is issued by the kernel when it mounts a filesystem
that's marked as clean, but whose `number of mounts since check'
counter has reached the predefined value. The solution is to get the
latest version of the ext2fs utilities (e2fsprogs-0.5b.tar.gz at the
time of writing) from the usual sites (Q2.5 `Where can I get Linux
material by FTP ?').
The maximal number of mounts value can be examined and changed using
the tune2fs program from this package.
9.14. EXT2-fs warning: checktime reached.
Kernels from 1.0 onwards support checking a filesystem based on the
elapsed time since the last check as well as by the number of mounts.
Get the latest version of the ext2fs utilities (see Q9.13 `EXT2-fs
warning: maximal count reached').
9.15. df says Cannot read table of mounted filesystems.
There is probably something wrong with your /etc/mtab or /etc/fstab
files. If you have a reasonably new version of mount, /etc/mtab
should be emptied or deleted at boot time (in /etc/rc.local or
/etc/rc.d/*), using something like
rm -f /etc/mtab*
Some versions of SLS have an entry for the root partition in /etc/mtab
made in /etc/rc* by using rdev. This is incorrect -- the newer
versions of mount do this automatically.
Other versions of SLS have a line in /etc/fstab that looks like:
/dev/sdb1 /root ext2 defaults
This is wrong. /root should read simply /.
9.16. fdisk says Partition X has different physical/logical ...
If the partition number (X, above) is 1 this is the same problem as
Q9.17 `fdisk: Partition 1 does not start on cylinder boundary'.
If the partition begins or ends on a cylinder numbered beyond 1024
this is because standard DOS disk geometry information format in the
partition table can't cope with cylinder numbers with more than 10
bits. You should see Q4.1 `How can I get Linux to work with my large
disk ?'.
9.17. fdisk: Partition 1 does not start on cylinder boundary
The version of fdisk that comes with many Linux systems creates
partitions that fail its own validity checking. Unfortunately if
you've already installed your system there's not much you can do about
this, apart from copying the data off the partition, deleting and
remaking it, and copying the data back.
You can avoid the problem by getting the latest version of fdisk, from
Rik Faith's util-linux package (available on all good FTP sites).
Alternatively, if you are creating a new partition 1 that starts in
the first cylinder, you can do the following to get a partition that
fdisk likes.
1. Create partition 1 in the normal way. A p listing will produce the
mismatch complaint.
2. Type u to set sector mode and do p again. Copy down the number
from the "End" column.
3. Delete partition 1.
4. While still in sector mode recreate partition 1. Set the first
sector to match the number of sectors per track. This is the sector
number in the first line of the p output. Set the last sector to the
value noted in 2. above.
5. Type u to reset cylinder mode and continue with other partitions.
Ignore the message about unallocated sectors - they refer to the
sectors on the first track apart from the Master Boot Record, which
are not used if you start the first partition in track 2.
9.18. fdisk says partition n has an odd number of sectors.
The PC disk partitioning scheme works in 512-byte sectors, but Linux
uses 1K blocks. If you have a partition with an odd number of sectors
the last sector is wasted. Ignore the message.
9.19. mtools says cannot initialise drive XYZ
This means that mtools is having trouble accessing the drive. This
can be due to several things.
Often this is due to the permissions on floppy drive devices
(/dev/fd0* and /dev/fd1*) being incorrect -- the user running mtools
must have the appropriate access. See the manpage for chmod for
details.
Most versions of mtools distributed with Linux systems (not the
standard GNU version) use the contents of a file /etc/mtools to
discover which devices and densities to use, in place of having this
information compiled into the binary. Mistakes in this file often
cause problems. There is often no documentation about this --
distribution packagers please note that this is *evil*.
For the easiest way to access your DOS files (especially those on a
hard disk partition) see Q3.2 `How do I access files on my DOS
partition or floppy ?'. Note -- you should never use mtools to access
files on an msdosfs mounted partition or disk !
9.20. At the start of booting: Memory tight
This means that you have an extra large kernel that means that Linux
has to do some special memory-management magic to be able to boot
itself from the BIOS. It isn't related to the amount of physical
memory in your machine. Ignore the message, or compile a kernel
containing only the drivers and features you need (Q7.6 `How do I
upgrade/recompile my kernel ?').
9.21. You don't exist. Go away.
This is not a viral infection :-). It comes from various programs
such as write, talk and wall, if your invoking uid doesn't correspond
to a valid user (probably due to /etc/passwd being corrupted), or if
the session (pseudoterminal, specifically) you're using isn't properly
registered in the utmp file (probably because you invoked it in a
funny way).
