Could You fix your /etc/lineakkb.def ? It contains this line:

 END.....

and should:

 [END....

[Comment 4 Jason McGuiness 2005-09-27 11:41:48 UTC]

Yes, I fixed it, and it started up. Clearly there are at least two bugs, 
lineakconfig is not robust enough at start up with regards to parsing the 
configuration file, and the configuration file has an error in it. Oops! :)

[Comment 5 Krzysztof Pawlik (RETIRED) 2005-09-27 11:46:53 UTC]

lineakconfig is very, very fragile when it comes to config files. I'm marking it
as INVALID, please open new one about lineakd's config.
