~jhs/tech/ncd/notes NCD 16e & NCD19 X-Terminal load sequence with FreeBSD-3.4 servers running inetd, bootpd arpd, named, tftp, xdm, By Julian H. Stacey Preamble: The V2 servers run OK on 4 * 0.25M RAM slices. V3 servers need more. HOST SLOTS OCCUPANCY & SIZE & SPEED NCD16 8 4 x 1M-80 (was 70ns till Jan 2000) + 4 x 0.25M NCD19 8 4 x 1M-80 + 4x0.25M 4 NEC * 8 * NEC421000-80 + 4 NCD * 2 * KM44C256AP-10 Manual says 100nS is OK for some or all NCDs) To manually boot: bt ncd/servers/Xncd16e 192.168.91.25 192.168.91.24 To escape Server: compose_character + compose_setup=F3 ==> menu config To upload a new file: mouse: Setup, Change Setup Parameters, top left click, Maybe NCD only uploads non blank fields ? Paths used by ncd install script TFTP_DIR="/tftpboot" MOP_DIR="/usr/lib/mop" # or /usr/lib/dnet/*.sys FONT_DIR="/usr/lib/X11" Boot Sequence (in the order the NCD boots, to help diagnosis): --- NCD19 broadcasts with IP 0.0.0.0 to ff.ff.ff.ff for its IP number, so ensure /etc/inetd.conf contains: bootps dgram udp wait root /usr/libexec/bootpd bootpd /etc/bootptab & /etc/bootptab contains: # ncd16 ncd_small:ht=ether:ip=192.168.91.25:ha=0x00.00.a7.10.28.8a: # ncd19 ncd_big:ht=ether:ip=192.168.91.29:ha=0x00.00.a7.10.66.b6: NCD then loads a server via tftp, so add this directory to /etc/inetd.conf EG: tftp dgram udp wait nobody /usr/libexec/tftpd tftpd -l \ /public/tftp/ncd /usr/lib/X11/ncd tftpd routes through symbolic links (EG /usr/ncd -> /usr4/ncd), this may be considered a security hazard, but means there is no need to also specify /usr4/ncd to tftpd via /etc/inetd.conf Ensure /etc/syslog.conf has ftp.info /var/log/ftp.log so you get a log of what loads & what fails. NCD19 looks for a server executable file, in each of the tftp root directories specified when tftp starts (ie specified in inetd.conf usually), using names in this order: for NCD19: C0A85B1D, Xncd19.50, Xncd19 (IP address 192.168.91.29 = 0xC0.A8.5b.1d) or for NCD16: C0A85B19, Xncd16e.50, Xncd16e if that fails, NCD tries prepending its inbuilt path of /tftpboot/ EG /tftpboot/Xncd19.50, /tftpboot/Xncd19, /tftpboot/C0A85B1D. so create sym links: ln -s servers/Xncd19 ln -s servers/Xncd16e To abort loading, manual says hit escape twice; PF1 also works. Server starts, & looks for a configuration file in tftp-dirs trying file names in this order: configs/unknown, configs/0000a71066b6, configs/192.168.91.29, configs/ncd_std Fonts load: The X11.R4 server can't cope with compressed fonts. The Xncd19.V3.0.1 can not cope, & (testing 2000.08.16 it appears) Xncd19.V2.2.0 also can not cope. Xncd16e.V2.2.0 uses .snf (big endian) fonts from inbuilt path EG: /usr/lib/X11/ncd/fonts/misc/fonts.dir /usr/lib/X11/ncd/fonts/misc/10x20.snf & tape supplied data EG: /public/tftp/ncd/fonts/100dpi/ /public/tftp/ncd/fonts/75dpi/ /public/tftp/ncd/fonts/dw100dpi/ /public/tftp/ncd/fonts/dw75dpi/ /public/tftp/ncd/fonts/misc/ /public/tftp/ncd/fonts/oldx11/ Xncd16e.V3.0.1 uses .pcf fonts from built in internals, & other pcf fonts (EG from X11R6) if available. Xncd16e.V3.0.1 Xncd19.V3.0.1 have the embedded string dw100dpi ( Xncd19.V3.0.1 has emitted the following error: %FILE-E-NOREAD, unable to read font directory: \ /usr/lib/X11/ncd/fonts/pcf/dw100dpi/fonts.dir %FILE-E-NOREAD, unable to read font alias file: \ /usr/lib/X11/ncd/fonts/pcf/dw100dpi/fonts.alias ) Xncd16e.V3.0.1 when started with a config file specify only internal: %FONT-I-REQ, requesting font: 8x13 %FONT-I-REQ, requesting font: -misc-fixed-medium-r-normal --13-120-75-75-c-80-iso8859-1 %FONT-I-OPEN, opening bitmap font file: @8x13.snf.Z %FILE-I-READ, reading font file: @8x13.snf.Z which seems to suggest it can maybe also use snf fonts EG fonts/misc/8x13.snf.gz (or maybe it was just compiled in) Xncd19.V3.0.1 does not recognise *.spd in Speedo/ or */pfb in Type1/ Key Table is loaded Xncd16e.V3.0.1 (but not Xncd16e.V2.2.0) looks for /usr/lib/X11/ncd/XKeysymDB so add sym links cd /usr/lib ; ln -s ../local/lib/X11 cd /usr/lib/X11 ; ln -s /public/tftp/ncd cd /public/tftp/ncd ; ln -s ../../../../../usr/local/lib/X11/XKeysymDB RGB is loaded: Xncd16e.V2.2.0 & Xncd16e.V3.0.1 read by default /usr/lib/X11/ncd/rgb.txt servers have inbuilt rgb & font paths of /usr/lib/X11/ncd so if the config file does not rest these, a simpler work around is to create symbolic links: /usr/lib/X11 -> ../local/lib/X11 /usr/lib/X11/ncd -> ../../../public/tftp/ncd Xncd16e.V3.0.1 & Xncd19.V3.0.1 (but not Xncd16e.V2.2.0) uses XDMCP NCD broadcasts a request for XDM capable servers, which requires a name demon to be available Ensure some host has /etc/rc.conf with: named_enable="YES" & /etc/namedb/* is OK Ensure /usr/local/lib/X11/xdm/* are OK, EG xdm-config Xservers etc log then shows: host "192.168.91.24" connected with MIT-MAGIC-COOKIE-1
