Dear (more knowledgeable than me) Ladies and Gentlemen, We have recently begun implementation of Koha 1.2.2 on a PC running RedHat 7.2 for the International Center at the University of Virginia. The server is iclibrary.lib.virginia.edu with the intranet interface being at iclibrary.lib.virginia.edu:8080. I have been unable to get the Z39.50 module to function. Any insight that you could offer on this would be greatly appreciated! Here is a description of the problem: I have downloaded and installed the latest Yaz rpm for the i386 architecture. When I attempt to run /usr/local/koha-1.2.2/scripts/z3950daemon/z3950-daemon-launch.sh as root, I get the message: -sh: /usr/local/koha-1.2.2/scripts/z3950daemon/z3950-daemon-shell.sh: Permission denied I have, through commenting out various lines, determine that it is this line in z3950-deamon-launch.sh, near the end, where the problem occurs: su -s /bin/sh -c $KohaZ3950Shell - $RunAsUser & Why, I cannot determine. RunAsUser=apache is set earlier in the script, and using the line echo $KohaZ3950Shell $RunAsUser in place of the above su command returns /usr/local/koha-1.2.2/scripts/z3950daemon/z3950-daemon-shell.sh apache as one might expect. The user apache is defined in /etc/passwd. Thanks C David Rigby cr8s@virginia.edu
