Top Forums UNIX for Advanced & Expert Users allow user to use sudo cp on a specific directory and only a specific file Post 302553933 by Peasant on Friday 9th of September 2011 08:10:04 AM

I would reccomend you check setuid.

You can make a shell script and a small c program to call it with root privileges.

So an example :
You make shell script with USER named test.sh which does cp file1 /etc/
Then you make a C program called execshell (or whatever) which runs that script with system call ( please find examples online for C setuid and system call )

Compile that program.

As root you make chown root:root and chmod 4755 to that C program.
User can now invoke that c program which will execute that shell script with root permisions and copy the file1 to /etc/ as root invoked by USER.

Be carefull tho, setuid needs to be handled with care.
passwd would be a lovely example of setuid in C and exceptions it uses.

Hope that helps.
Regards
Peasant.

NAME
heimdal_debug -- how to turn on/off debugging for Kerberos tools DESCRIPTION
The heimdal_debug kerberos frameworks have several knobs for controlling logging. The different framework knobs are: libkrb The Kerberos library, some gss-api Kerberos output ends up here too kcm the kcm library (credentials cache, ntlm client) kdc the kerberos KDC output digest-service the digest service (ntlm server) CONFIGURATION FILE
[logging] <subsystem> = 0-/SYSLOG: and watch syslog for logging information. APPLE MAC OS X
First turn up syslog debugging sudo syslog -c 0 -d then you can see the syslog output in Console.app or by running syslog -w -k org.h5l.asl To enable more extensive debugging logging for each subsystem, use the following commands: Kerberos Library sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add krb5 '0-/ASL:' digest-server sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add digest-service '0-/ASL:' kcm sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add kcm '0-/ASL:' kdc sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add kdc '0-/ASL:' MIT Kerberos Shim defaults write com.apple.MITKerberosShim EnableDebugging -bool true GSS-API framework logging sudo defaults write /Library/Preferences/com.apple.GSS DebugLevel -int 10 Other options on Mac OS X Make the admin API pretend to the server even on client sudo defaults write /Library/Preferences/com.apple.Kerberos ForceHeimODServerMode -bool true SEE ALSO
