Re: S390 Debian Installation Problem
Stefan, Mark Thanks for the replies. Could you set up an HTTP or FTP server on your NFS server if this problem can't be fixed? You don't even have to do this as root, an HTTP server on any TCP port will do. I used a Linux PC that had no CD drive but had a HTTP server. I nfs mounted the CDROM on newton to a point named debian in the DocumentRoot of the HTTP server. I used the network method to do the base installation after the kernel and drivers installation, specifying the HTTP server name/debian as the URL. This worked fine. This might be a problem with the NFS version. Could you open a shell from dbootstrap and try to manually mount the NFS filesystem using mount newton:/cdrom/cdrom0/dists/woody/main/disks-s390/current \ /instmnt -o nolock,nfsvers=2 During the installation process and at the point where you select install the kernel and driver modules I manually nfs mounted the CDROM using the parameters above. This worked fine! I then chose install from a local file system and selected my nfs mount that appeared in the menu. This worked fine too and a kernel was found (no need to specify the full path to its location on the CD) and installed. Thanks for the help, Stefan. I now have one minor problem. I am using an OSA-2 adaptor as eth0 on my built system and it is not recognized at boot time. I need to manually do insmod lcs then wait for a few seconds before issuing ifconfig eth0... and route add default gw. Just a minor inconvenience at the moment. Geoff McKee Emirates Airline Dubai UAE

I don't think Bochs is kernel-level-sensitive, though. It should work OK under 2.2.16. The tricky thing is, you can't currently *install* NT under Bochs on Linux/390. I think this is due to some endianness bug in the ATAPI CD emulation, because it blows up with an unsupported ATAPI command. So what I did was (skipping all the false starts): Install Bochs on x86. Follow the HOWTO to install NT under Bochs. The tricky part here is to get the boot-floppy right, because booting from the CD gave me nothing but grief. You have to get a workable generic IDE CD driver, SMARTDRV.EXE, and MSCDEX.EXE, plus FORMAT and FDISK. I used the DOS in Win98 to create this boot disk, but I see no reason it wouldn't work with MS-DOS or PC-DOS or (probably) DR-DOS. And you don't really *need* SMARTDRV.EXE, but I think it's going to make life faster. I don't really remember whether I used it or not. I'll be happy to supply the boot floppy image to anyone who wants it, or I can give it to Mark to put up on his site. I've got a dos95 boot disk I use for most of my Bochs installation stuff. I would be happy to add it to the collection, if you think it might be useful - it's got fdisk and format, smartdrv, mscdex, oakcdrom.sys (universal [MS | PC | DR] DOS driver), attrib, and suchlike on it, including autoexec.bat and config.sys files. I've also got an msdos-6.22 boot disk, but that one's not nearly as useful - no cdrom driver, etc. Wesley Parish Then you use dd to create an iso image of the NT CD. Then use the bochs diskimage utility (don't remember the name) to create a suitably-sized hard disk image. I think mine was 504M. Set up Bochs with the emulated floppy in drive A, the disk in drive C, and the NT ISO image in drive D. Boot from floppy. Fdisk and format the hard disk, reboot, and run the NT installer from the CD. Sit back and wait a long long time; when you reboot make sure you're booting from the HD image, not the CD or floppy. I used standard VGA and no mouse for my install; I don't know if that's necessary or not. Once you've done that and set up NT (I set up a network card but did not ever actually configure the network), shut it down cleanly. Now copy the hard disk image over to Linux/390. Build Bochs there. Tell it the geometry of your disk, and boot from it. That's all it takes. Adam -- Mau e ki, He aha te mea nui? You ask, What is the most important thing?

While byte order is a certainly a factor, it is not specific to the 390 platform, and so is less likely to be an issue than truly platform-specific code.

Is there anything else you can tell me? Don't confuse SuSE's default starting point firewall configuration with containing the total capabilities of IPTABLES. SuSE doesn't claim that their default config is comprehensive. IPTABLES can do a *lot* of neat things. IPTABLES is the current Linux packet filtering control utility. The actual filtering is within the kernel. IPTABLES replaces the older (kernel 2.2.x and earlier) IPCHAINS and IPFWADM which are both deprecated. Typically, packet filtering consists of a group of inter-related modules. It is rarely, if ever, built into a monolithic kernel. Fortunately, IPTABLES is similar enough to IPCHAINS that migration is typically not difficult. If you *really* need full backward compatibility, you can load the old ipchains.o kernel module instead of iptables.o and friends, and thereby actually use the old IPCHAINS commands. I don't recommend doing this as a general rule, especially for new installations. Migrate to IPTABLES. In addition to the IPTABLES HOWTO (also look for HOWTOs and Mini-HOWTOs on NAT and Packet Filtering -- there are several), you may also want to take a look at the tutorial presentation I did for SHARE Nashville. It's online on Sine Nomine's web site, in our Publications section.

Now that Debian has been GA for a while, I finally generated a list of all the software packages that are available with it. Thanks to Stefan Gybas for pointing me to what I needed to start with. The list is quite large, 8,000+ .deb files, so the web page is also quite large, 4MB+. Since I was in there updating things anyway, I also went through and updated the entry for Red Hat to show the contents of their GA release, and not the RC2 that had been there up until now. I copied the updated Red Hat information into the consolidated list (1.3MB) as well.
