PP's ncpfs contributed code

1. CUPS printing to a Netware queue
2. Make a full NDS context "Linux Ok" in 5 minutes

• CUPS printing to a Netware queue

  make sure nprint is working by nprint -S server -U user -P password -N -q queue_name /etc/hosts Find & download cups-backend-ncp package on rpm.pbone.net (this package is only known for russian ALT Linux distribution) Install the package. You may have to use --nodeps option if your cups version is not 1.1.1.18 (harmless). It will just add two perl scripts ( ncp and nprint) in /usr/lib/cups/backend Edit the /usr/lib/cups/backend/ncp script to change $NPRINT variable to your location of nprint (/usr/local/bin/nprint) required Ignore or delete the /usr/cups/backend/nprint script. I don't know it purpose. Alternatively you can download the ncp script from here , rename it to ncp, copy it in /usr/lib/cups/backend and chmod it 755.. July 2005 : an improved version of ncp script was contributed by Erez Geva. (see his comment atop the script) Restart cups by service cups restart required . With the CUPS Web interface (http://localhost:631) add a printer, select "NetWare Printer via NCP" in the second screen. use ncp://user:password@server/queue_name as the URI Finish configuration as usual. That's it... Troubleshooting : Check /var/log/cups/error_log for exit code of nprint. You may want to use this version of nprint . that has a different exit code for all errors (instead of returning 1 for all errors). Copy it in ncpfs/util source directory and make ; make install.

• Make a full NDS context "Linux Ok" in 5 minutes... Ok 15 minutes ;-)

  Since we are going to use Dos based utility, uimport, this operation can only be done one context at a time (I think). For this example we will suppose that we want to assign unique Unix IDS to all members of context GCP.PC. Get a list of all users of this context one per line using any Dos based utility or use ncplist from a Linux box: (ncplist is in ncpfs/contrib/tcl-utils that is not installed by default, so cd there && make && make install). ncplist -o GCP.PC -l user -Q -v 4 -c GCP.PC -A |sort >linuxgcp.txt -o context to scan -l class to scan (user) -Q quiet, only user's CN -v 4 use typeless names -c GCP.PC use this a default context -A do abbreviate typeless names You should get a list like this one: atoumine cbignon ccarton csubai ctouboulic ... Decide what sequence of Unix UIDS you plan to assign them, say starting at 2000. and where will be the homes, say on a NFS remote server locally automounted as /nfs/home, finally to make things easier we add then to a NDS group say linuxok.pc open the text file linuxgcp.txt with a spreadsheet and remove any 'unwanted user'. using the incremental copying feature create a second colomn with number 2000,2001... down to the last user. In first cell of column 3 use the formula =concat("U:";A2) and copy down the column In first cell of column 4 use the formula =concat("H:/nfs/home/";/A1) and copy down the column Fill all column 5 with the group name linuxok.pc save as a CSV file (strings surrounded by quotes, comma separated) as linuxgcp.csv You should get something like : "atoumine",2000,"U:2000","H:/nfs/home/atoumine","linuxok.pc" "cbignon",2001,"U:2001","H:/nfs/home/cbignon","linuxok.pc" "ccarton",2002,"U:2002","H:/nfs/home/ccarton","linuxok.pc" "csubai",2003,"U:2003","H:/nfs/home/csubai","linuxok.pc" "ctouboulic",2004,"U:2004","H:/nfs/home/ctouboulic","linuxok.pc" ... Now from a Dos workstation prepare the following control file for uimport, says linuxgcp.ctl (argh, my uimport wants french headings !) ;linuxgcp.ctl CONTROLE IMPORTATION MODE D'IMPORTATION=U <-- update CONTEXTE DE NOM="gcp.pc" <-- set to the target context SEPARATEUR=, <-- comma is separator, can be changed LIBELLE=" <-- quotes around strings REMPLACER LA VALEUR=N <- DO NOT replace values !!! NBRE DE REESSAIS DE REPERTOIRE MAX=5 FIELDS Name Skip Location Location Group MemberShip make a test data file with the first two lines of the linuxgcp.cvs -> test.cvs Give it a go by uimport linuxgcp.ctl test.cvs Check with NWADmin that everything is OK. The 2 first users should have two extra Location strings (U:2000 and H:/nfs/home/atoumine...) and be members of group LinuxOK.PC Remove the two first lines of the real data file and run uimport linuxgcp.ctl linuxgcp.cvs.... That's it. Your NDS Unix properties are set. Now your users should be authenticated with their login/password on a linux box with the following settings in /etc/pam.d/system-auth # adapt server, list of contexts and control group names #use -d to see what happened in /var/log/secure auth sufficient pam_unix.so ..... auth required pam_ncp_auth.so -d -u,,r,gcds ndsserver=myserver:GCP.PC/LinuxOK.PC ... session optional pam_ncp_auth.so and a local dummy directory /nfs/home in which homes will be autocreated What's left to be done ? using the pam snapin (or in the pam_ncp_auth command line, set some nice zenflags such as -zA (automount Netware home) Set up a NFS server for homes Set up NFS mounting on workstations (either in /etc/fstab or using autofs but name must be /nfs/home)). Run on the ncpfs enabled NFS server the synchronization script with the -F option. This will create a /tmp/ndsfixlinuxok.pc.sh script that you can run to setup all homes (creation, permissions and initial copy of some files from /etc/skel). Destroy the /nfs/home on test workstations. add -l -n to the pam_ncp_auth command line to force it not to create homes and automount Netware home locally. Use the pam snapin to set 'Next Unix Id' to use when manually adding users with NWAdmin to one plus the last number you have assigned here. take care of NDS to Unix groups synchronization. have fun ;-)
