QUESTION
I have the following code in which I try to check if the machine obtains it's IP adress from dhcp or if it's static. The code has to work for both ubuntu and sles 12. Now if I'm using the code on sles I get an error that the file is not found which is normal. But I don't want the user to see this message. Is there a way to redirect the output of an if statement? Normal redirection doesn't seem to work.
I already tried putting if [[ ${statement} ]] &> /dev/null after the if statement but that doesn't change a thing.

QUESTION
Unable to isolate kea logs based on severity level.
...ANSWER
Answered 2019-May-02 at 21:44From a quick reading of Section 18 of https://jenkins.isc.org/job/Kea_doc/guide/kea-guide.html, I would:
- Try to put the debug log section before the warn log section to see if only warnings get logged.
- Check the keactrl configuration.
It would appear that you can only have one log per "name" and that if you want debug logging, you would have to use a different logger name, eg. "kea-ctrl-agent" instead of "kea-dhcp4" - but it's unclear if there's a hierarchy involved and if that will catch entries of parts below it.
It should be easy to fix for the developers if it is the case - you should update the bug report in the kea project, here: https://gitlab.isc.org/isc-projects/kea/issues/592
Some other things that you could do is to log everything to syslog, and send it to a remote log and use something like splunk or logzilla to sort them by severity.
Or you if it's just temporarily, you could create a cron job that does this every few minutes, or just run it on a tail:

QUESTION
OS : Fedora 26 Alpha
Kernel : Linux 4.11
Kernel Manually compiled by following commands:
1) make oldconfig
2) make menuconfig
3) make all
4) make module_install
5) make install
After successfully compilation and installation of Latest Kernel ,
i build some modules but as a external modules via make -C /root/linux-4.11/ M=$(pwd) modules not as against running kernel.
All basic modules that i developed compiled and installed and worked as expected , but then i code basic character device driver , but then some strange problem i detected. That is, after successfully compilation and insertion of module via insmod , i didn't get any kernel messages regarding this module and also no char device was generated in /dev/ directory then I also searched regarding this issue but didn't get any better answer for this same issue.
Then , suddenly i tried it to be compiled and build against as running kernel via make -C /lib/modules/$(uname -r)/build/ M=$(pwd) modules then after inserting module , i get my expected result.
But now , i want to figure out why this is happening because other simple modules are working fine when build as external module , but then why not this one?
ANSWER
Answered 2017-May-10 at 14:00The warning about the missing Module.symvers indicates that the kernel you're building against is missing the CONFIG_MODVERSIONS option. You need to enable this option to be able to sometimes load modules built against a different kernel. The problem can also happen if the kernel source that you're building against is not fully compiled and the file has not been generated yet.
