Cyberspace installation Current state summary Cyberspace is UCLA 994012442. running only Linux. I installed Linux using the SuSE 7.3 disks, and followed in broad parts the instructions from the SuSE installation, which was done on Gubbio, my home machine. Cyberspace now runs a web server at 128.97.184.95, along with Samba, vsFTPd, and TightVNC. It's always left on. Font `-misc-fixed-medium-r-normal-20-200-75--75-c-100-iso8859-*' not
found Bootup instructions Cyberspace currently has a problem with Lilo -- the bios doesn't support a USB keyboard, so if you want to load a kernel that is not the default, you need to plug in the PS/2 keyboard. Modules autoload, so you shouldn't need to manually load the firewire modules, or any other. The /vc file system (ext3) is on /dev/hdb1 and will automount both on cyberspace and on gubbio. This is robust and has worked for a long time. (Note that on 24 September 2002 I switched /vc from LVM to ext3.) The /vd file system (ext3) is on /dev/hdd1 and will NOT automount. This is the DeathStar drive that doesn't want to be powered for more than 8 hours a day. Both of these drives take the hdparm -S 242 /dev/hdb or /hdd setting -- they will then spin down after an hour of idleness. You can use the -k switch to make this stick through a warm boot (soft reset), but it has to be re-issued if you power it down. Installation summary On 29 October I upgraded the kernel, so that I can use the new dv1394io utility on cyberspace. It was a hassle -- especially sound. It would have been faster to install Libranet. On 10 Mar 02 I upgraded the Bios on Cyberspace from A06 to A07 and defined the zip drive as drive B:, which also makes it bootable. I've not tried to access it under Linux and don't know if Linux can handle this arrangement. If not, just go into the bios setup (F2 at bootup) and change the zip drive back to a normal ATAPI drive. Cyberspace has user root and user steen. On 10 Mar 02 I also updated XFree86 from SuSE's 4.1 to SuSE's update 4.2 (see below). I also got the files for SuSE's 2.4.16 kernel, including the source code, but I didn't install it. I'm hoping I may be able to use the source code to make a new kernel, after patching it with the gigadrive patch. On 15 March 2002, I installed a security update from SuSE, the libz update at ftp://ftp.suse.com/pub/suse/i386/update/7.3/a1/. I performed the update on both Gubbio and Cyberspace. I downloaded the rpm file into the root directory switched to the command line with Alt+F2. Then I did "init S" or Single User Mode. This shuts down a lot of programs, including the NIC card, placing the system in a good mode for fundamental upgrades. I then ran the rpm file with the command "rpm -Fhv <filename>" It went fine. Single User Mode could also be useful in the case of a hacker attack, as it basically shuts you off from the world. On 25 April 2002 I installed TightVNC -- see details. I did it all remotely, through VNC and SSH. On 26 April 02 I installed xcpustate, a cpu monitor. I checked the SuSE Pro site and found it's in xap3 in 8.0, which turned out not to be the same as 7.3, where it is in xap2. I then went to the gatech mirror and kept running into password requests. I found the file at ftp://chuck.ucs.indiana.edu/linux/suse/suse/i386/7.3/suse/xap2/, and I also discovered that you can download 8.0 for free, so I might do that. For some reason, however, I was unable to retrieve the rpm from any of the mirrors, using any Linux program (I tried KBear, Konqueror, and Opera); I ended up having to get it using my local Windows machine and save it on Nicco. It works fine, but this was a hassle. On 29 April 2002 I worked on the Apache web server -- see details. On 9 May I looked into disabling nscd, the Nameserver Cache Daemon -- it doesn't appear to be required; cf. instructions. (I ran the program top for the first time, to get a sense of active systems and resource use -- there are lots of instances of nscd running, and then it turns out they're not needed). Basically I just stopped nscd with /etc/init.d/nscd stop and then went into /etc/rc.config and changed "Run the Name Service Caching Daemon at boot time" to no -- and then did a /etc/init.d/inetd reload. It's possible that it was nscd that was causing me grief trying to establish virtual hosts yesterday! I also looked into /etc/inittab -- the main init configuration file -- to see why I have so many mingettys. I gather I have six so that they can all be accessed with Ctrl-Alt-F1 through F6. Three is surely enough? I commented out mingetty 4, 5, and 6 -- how do you reload inittab? It turns out you use telinit q. This worked great -- the last three mingettys are gone and the top list looks more tidy. On 11 May I installed gprename -- see details. On 12 May I installed GKrellM, a system monitor. I had to install gtk-devel, imlib, and imlib-devel to compile it. On 25 May 2002, I got powertweak 0.95 from CVS. To configure it, I had to get libxml2-devel from SuSE. It runs fine, and reports the CPU is running at 800MHz. On 25 May 2002, I got the file k_i386-2.4.16-35.i386.rpm from SuSE's
kernel update directory. I renamed vmlinuz vmlinuz.2.4.10 and created
a new entry in lilo. I ran lilo to make it stick. On 23 June 2005, three years later, the replacement CPU
failed. It may just have been really dusty and shorted out, but since
I'm leaving the country for three months soon, I just replaced it with
the original CPU. It's possible that these replacement CPUs don't last
as long -- the one on gubbio also started having problems after a
while, and I replaced it with the original. Things seem to be running
fine now and CPU speed isn't a big deal for servers. Installation details XFree86 Upgrade I downloaded the new XFree version 4.2 in SuSE's RPM from here: At the same place, I downloaded the xf86-glx, since I had 4.1 installed I also got xdevel, for the same reason (packager showed 4.1) xf86tools contains the fetchmsfonts script, so I updated it. Ditto xman, fntscl (scalable fonts), xloader, xshared, and xmodules. Then I got the SAX2 update and saxident at saxident provides provides /usr/X11R6/lib/sax/sysp/maps/Identity.map When I installed xf86, I got this: Dependency Problems: I seem to be missing a vital libX library -- lots
of xf86 xshared had reams of dependency problems -- xf86-glx Since xf86-glx is for 3D rendering, I I believe I don't have it anyway,
I xdevel xftools provides xf86/usr/X11R6/bin/fetchmsttfonts xserver provides x_server, XFree86-V4L xmodules provides vmware-driver, gamma_dri.so, mesa_dri.so, tdfx_dri.so, xfntscl provides x312fscl, fntscl, speedo, x311fscl xman provides x312man, x311man, xman1, xman3 The trouble is the libX library. It's provided by xshared, which I finally ran after unchecking "check dependencies" and then ran ldconfigxshare provides: xpm, XFree86-libs, x, libICE.so.6, libSM.so.6, libX11.so.6, libXIE.so.6, libXTrap.so.6, libXaw.so.6, libXaw.so.7, libXext.so.6, libXfont.so.1, libXft.so.1, libXi.so.6, libXmu.so.6, libXmuu.so.1, libXp.so.6, libXpm.so.4, libXrandr.so.1, libXrender.so.1, libXt.so.6, libXtst.so.6, libdps.so.1, libdpstk.so.1, libpsres.so.1, libxrx.so.6 At that point, xf86 itself installed, nicely showing the xshare files as dependencies. It provides: xtermutf, xterm, xfntbig, xfntgrk, xfntgr, xdoc, xlkit, XFree86, XFree86-tools, XFree86-xfs, XFree86-twm, XFree86-xdm, XFree86-75dpi-fonts, XFree86-ISO8859-2-75dpi-fonts, XFree86-doc, XFree86-xf86cfg, x311bin, X, X11, x11, x312bin, x311cfg, x311ctrb, x311f75, x311fnt, x311ubin, x312cfg, x312ctrb, x312f75, x312fnt, x312ubin, xf_bin, xf_cfg, xf_ctrb, xfnt, xfnt75, xusrbin, xf86_40, libximcp.so, libxlcDef.so, libxlcUTF8Load.so, libxlibi18n.so, libxlocale.so, libxomGeneric.so Kernel Left for later. I downloaded SuSE's 2.4.16 kernel rpm from 20 Dec 01 here: I followed the instructions from here, as copied below:
I see packages for jfsprogs, k_deflt, and the source code -- I should
get
lspci from 4 September 2002:
