Please can you help me? Thanks

Hi @tiigaaa!

I will try to point you in the right direction!

I notice in the error message you get here, it says:

Can't open ./syntax_verify_config: Permission denied

This suggests an issue with the linux user permissions; it seems like the linux user that is running fiberglass and attempting to save the DHCP config file does not have permissions to run/open the ./syntax_verify_config file.

So you'll want to look into the linux users that you're using and make sure those users have proper permissions. One thing to note, you probably want to install fiberglass as root; if you didn't, that may be causing a permissions issue here.

Another hypothesis: When you save a DHCP config file in fiberglass, it writes it to that file named syntax_verify_config so that it can run /usr/sbin/dhcpd -t -cf ./syntax_verify_config against it to check for DHCP config syntax errors.

It appears that perhaps /usr/sbin/dhcpd does not have permission to open the syntax_verify_config file when it tries to run against it. This could also be related to the linux user that is running fiberglass, as that is probably determining which user writes the syntax_verify_config file, and therefore that file's permissions.

Hope this helps! My apologies, but I don't currently have a lot of resources to devote to support on this project.

HI again,

i have done chmod 777

For me it seems that he is ablte to write the "syntax_verify_config file but then it stucks.

The file /etc/dhcp/dhcpd.conf is also 777

I also have restartet the DHCP Server over the fiberglass GUI, and get this back POST /dhcp_start_stop_restart 200 3149.587 ms - 168 GET /dhcp_start_stop_restart?v_ajax 200 16.952 ms - 2494

After "POST /dhcp_config_save I just get the error, and nothing in the log.

But im still not able to edit the config file over the fiberglass gui. > I have also tried witrh glass, same error.

BR, THANKS :)

Is there anything i can do to get this working?

Hi @tiigaaa,

I notice in one of your screenshots that there is an error no such file or directory, open '/var/lib/dhcp/dhcp6.leases'. Are you trying to edit the v6 config file? If so, it looks like maybe the file name (dhcp6.leases) that fiberglass expects to edit isn't there?

I apologize, but I don't currently have the time/resources to devote to this. I cannot guarantee any troubleshooting help or support and may be slow to respond.

Sorry I cannot be of more assistance! If you find the problem and want to report back, feel free!

Thanks
