Configure the uls-client: Set the ulsserver ip-address or the ulsserver name in /etc/uls/uls.conf.

$ vi /etc/uls/uls.conf
...
ULSSERVER=<ulsserver>:11976

Check directory /var/tmp/uls for files, should look like:

$ ls -al /var/tmp/uls
drwxrwxrwt  2 uls  ulsuser   4096 Dez 23 14:40 .
drwxrwxrwt 14 root root    299008 Dez 23 14:40 ..
-rw-------  1 root root       929 Dez 23 14:40 dat-0-8550.uls
-rw-------  1 root root       789 Dez 23 14:40 dat-0-8575.uls
-rw-------  1 root root       400 Dez 23 14:40 dat-0-8602.uls
-rw-------  1 root root       381 Dez 23 14:40 dat-0.uls
-rw-------  1 uls  ulsuser    720 Dez 23 14:39 dat-900.uls

If no files are shown, check the crontab entries:

$ cd /etc/cron.d/
$ cat ulsclient

to verify that the crontab file has been created and the entries are activated.

If the files do not disappear (not transferred to the ULS-server), try:

$ flush_test_values -t

further explanation is needed.

To check, if an error condition exists, e.g. “ERROR from ULS-Server: NOSRV”, which means that the current hostname has not been set up as an ULS-client.

Setup a user that can access the ULS domain!

Values should appear after about 5 to 10 minutes.
