Subject: "Dropin's boot time commands" after kernel update
Date: Fri, 30 Jun 2000 13:22:05 GMT
I just updated my Mandrake 6.0 system to the 2.2.16 kernel. On reboot
partway through system initialization I get linuxconf popping up claiming
the state of the system is not properly in sync (it wants to change
permissions on the /home/ftp directory).
I let linuxconf do its thing, then as the boot proceeded a message
flashed by saying something about "Dropin's boot time commands."
(A little searching around indicated this has something to do with
linuxconf.)
Just wondering what happened here, first time I've seen something
like this after a kernel update...

Hi all,
The latest version of mkisofs support a new option "-eltorito-alt-boot"
this allows to specify more than one El Torito boot image (up to 63).
Anybody has an example on how to use, or where to find more info for this?
Regards,
Bart.

Perhaps you missed something. That command completely wipes out the MBR,
after which point not only will you not be able to boot, but your
partitions will be undefined. You'll need to restore EVERYTHING on the
disk from a backup or from original media.

I know that Win2K can be booted from LILO that's installed in a Linux
partition's boot sector. I've done that for testing purposes, and had
no problems with it. It's conceivable that NT/2K has problems when LILO
is in the MBR, but I've never tested that myself. It's also possible
that earlier versions of LILO couldn't cope with it, or that NT 4.0
couldn't cope with it but Win2K can.

Chances are these people just don't know about the FDISK /MBR command
(executed from a bootable DOS floppy). That will fix the problem, unless
something VERY strange is going on.

Correct. There are two possible causes and solutions:
1) If LILO is installed in the MBR, Win98 wipes out LILO by re-writing
the MBR (essentially FDISK /MBR, although I don't know if it actually
uses FDISK to do this). The solution is to boot Linux using a copy of
the kernel stored on a floppy along with the DOS LOADLIN program (or
in various other ways) and re-run LILO.
2) If LILO is installed on a primary Linux partition's boot sector,
then Win98 changes the active primary partition from the Linux
partition (and hence LILO) to itself. This bypasses, but does not
destroy, LILO. The solution is to use Windows' FDISK to make the
primary Linux partition bootable.

Once again, **DO NOT** do this on any system you care about. It'll make
it impossible to recover any data from the disk unless you know the
EXACT disk geometry and partition layout, and then only if you know
what you're doing. (Well, actually, somebody who REALLY knows their
stuff could reconstruct this information from the remaining contents of
the disk, but this process could get quite tedious, especially if you've
got lots of different filesystems on the disk.)

Actually, you can get them through the same links as you would for the
Windows version. Follow the links on http://www.real.com for the standard
real player, the Linux RPM beta and the self-installing script beta are now
in the list when you select your O/S.
The RP7 beta2 is the one currently available. Once installed you can find
the plugin installer through the Help menu.

Yes. Just install the imwheel package:

In theory, you can use the whois command to find who to mail about
problems at a site. For instance, "whois foo.com". Unfortunately, the
whois information is now scattered about, so it becomes a two-step
process, thus:
$ whois foo.com
{misc output, including something like:}
Whois Server: whois.corenic.net
$ whois -h whois.corenic.net foo.com
{Output on who's registered the domain, where the domain's nameservers
are, who to contact for technical and billing problems, etc.}
Alternatively, you can go to http://www.samspade.org and enter the name
in the appropriate spot to do it in one step. This site also has other
useful features; for instance, if you enter an IP address with no
reverse DNS lookup and click the "IP block" check box, you can trace
back who owns that IP address. That comes in very handy for tracking
spammers.
In the case of chewtoy.com, I e-mailed the address listed via whois and
got back a reply that the problem's been fixed, and indeed, I haven't
seen any duplicates from them in a day or so. I believe I also pointed
out that RFC 822 requires all domains to have a valid postmaster
address, but I got no acknowledgement of that point.

Overwriting the ENTIRE MBR with one from a random computer is a Bad
Idea, because the MBR includes partition table information. So unless
your "donor" has a drive that's EXACTLY the same size and has partitions
defined in EXACTLY the same way, you'll get incorrect partition
information. If your /dev/hdb partition information is missing anyhow,
then you're in deep trouble. If you know the exact sizes of that drive's
partitions, you may be able to reconstruct it.

DOS cannot normally be booted from /dev/hdb. There are some boot loaders
(like the Ranish Boot Manager,
http://www.users.intercom.com/~ranish/part/) that claim to allow this,
but I've never tried it.

That redirects it on the localhost (for example, if you're running
the transparent proxy on the same machine). To redirect it to
another host, use ipmasqadm.
ipmasqadm portfw -a tcp -L Linux_internal_ip 80 -R NT_internal_ip 8080
I'm a bit confused though. If the Linux box is the firewall,
wouldn't it be on the outside? Are you not firewalling the proxy?
