New subject: [PATCH] unbound-dhcp-leases-bridge: handle PTR generation parameter

13 Jul 2019


      Hi,
Sorry, but we're at it again...
DHCP-Configuration:
No addresspool, only fixed leases, working fine, no problems during
operation. And I mean it. NO problems! All clients are operational.
But a few days after adding a new host to fixed leases, I stumbled upon
a whole lot of error lines in '/var/log/messages'. One host, one line.
***SNIP***
dhcp[3480]: Could not parse line: on,[HOSTADRESS],[HOSTNAME],localdomain,on
***SNAP***
Today I tested this on a testmachine with a fresh install (Core 134):
- Activated dhcp (dhcp.cgi), added two fixed leases, just for fun.
- Added one host (hosts.cgi), page reloads and stays "Waiting for ...".
- Added second host (hosts,cgi), page reloads and stays "Waiting for
..." and the new host is not shown. No errors in
'/var/log/httpd/error_log/'!
- After playing a while with the testmachine I looked at
'/var/log/messages' and found a lot of 'could not parse line' errors
again. One error line for each host. Seems to be the same on my
production machine. ;-(
***SNIP***
dhcp[3480]: Could not parse line: on,192.168.100.50,test1,localdomain,on
dhcp[3480]: Could not parse line: on,192.168.100.50,test1,localdomain,on

***SNAP***
And this happens every time I restart 'dhcp' or add/edit a host.
Current '/var/ipfire/main/hosts' on testmachine contains:
***SNIP***
on,192.168.100.50,test0,localdomain,on
on,192.168.100.51,test1,localdomain,on
on,192.168.100.52,test2,localdomain,on
***SNAP***
Restarting 'dhcp' or editing a host gives me (e.g):
***SNIP***
11:06:50 dhcpd: Wrote 0 deleted host decls to leases file.
11:06:50 dhcpd: Wrote 0 new dynamic host decls to leases file.
11:06:50 dhcpd: Wrote 0 leases to leases file.
11:06:50 dhcpd: Server starting service.
11:06:50 dhcp[9159]: Could not parse line:
on,192.168.100.50,test0,localdomain,on
11:06:50 dhcp[9159]: Could not parse line:
on,192.168.100.51,test1,localdomain,on
11:06:50 dhcp[9159]: Could not parse line:
on,192.168.100.52,test2,localdomain,on
***SNAP***
'dhcp' and fixed leases are working though!
Can anyone confirm or has a hint were to look? I didn't find a grip on
this yet.
Best,
Matthias

Restarting dhcp or adding a host leads to "could not parse line"-errors in '/var/log messages'
