Troubleshooting SentryII on Linux

Description: The SentryII daemon won't start after installing on Suse or Mandrake even though the install seemed to complete successfully


  • The install program will sometimes place the .so files in a directory specific to Redhat and in other distributions, they cannot be found. You can test to see if this is your problem by typing the following commands in bash:
  • cd /usr/local/sbin
  • SentryII daemon -c ./SentryII.ini
  • If you see an error message similar to this:
  • SentryII: error while loading shared libraries: cannot open shared object file: No such file or directory
  • then this is the problem. To correct this problem, simply copy the .so files to the correct directory:
  • cp /usr/local/sbin/*.so /lib
  • Retry the SentryII daemon command above and it should now start the daemon correctly.
