Inadvertent Use of Duplicate Group ID
We were trying to limit the number of regular users who could use xterm or cmdtool for security reasons. A user-defined group was created and admins/non-regulars were assigned to it. Unfortunately, the admins/non-regulars were mysteriously denied xterm/cmdtool execution, which definitely was not the desired effect. Permission denied. That feedback was a bit perplexing because the admins/non-regulars were supposeably assigned to the newly created group per niscat. After a little troubleshooting, it was discovered the newly created group ID matched an existing group’s GID in a different name service database. The GID issue was corrected and xterm worked like a champ.
Display the Structure of a Nisplus Table
Building on the last post, I am using the niscat -o flag to display the structure of a common nisplus table. In the example below, the run shows the passwd table and its specific metadata/attribute information. Here is the syntax.
# niscat -o passwd.org_dir
Object Name : "passwd"
Directory : "org_dir.esofthub.com."
Owner : "esoft.esofthub.com."
Group : "admin.esofthub.com."
