Can't get zabcon to work

[gloover79]

Hello,

I can't get zabcon revision 172 to work.
I've compiled ruby 1.9.1 from source, updated rubygems to 1.3.6 and installed all required packages.
When I run zabcon, it gives the following errors and then stops.

/tmp/zabcon # ./zabcon
/tmp/zabcon/libs/printer.rb:93: warning: else without rescue is useless

Anyone seen this before or know how to solve this?
Thanx.

can you execute with debug information please?

zabcon -d8

In the meantime I'll have a look at the code in question.

Thanks

[nelsonab]

I've updated the case statements in revision 173. Turns out ruby 1.9 depricated a common syntax in Ruby 1.8 (what I use to develop Zabcon).

No need to run with debug information, however if you have another error it may be useful to have level 6 debug.

At the moment I am working on having the ability to add new items using Zabcon. Turns out there is a fair bit of bounds/error/input checking required to make it happen for all 7 item types. :-)

[bashman]

Hi nelsonab,

I have this output when I run ruby zabcon revision 183 2010-04-21:

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- readline (LoadError)
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
        from ./libs/input.rb:25
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
        from zabcon:35

I have ruby version for red hat 5:

ruby --version
ruby 1.8.6 (2007-03-13 patchlevel 0) [x86_64-linux]

Zlibs version:

zlibs-1.2.5
ruby-zlib-0.6.0

Ruby gem version:

gem --version
1.3.7

Packages version:

json-1.4.3
parseconfig-0.5.2
highline-1.5.2

Anybody know how to solve this?

[richlv]

gem install readline

or similar.

[bashman]

Thanks for your reply

ERROR:  Could not find a valid gem 'readline' (>= 0) in any repository

[richlv]

well, duh - read the dependencies file

gem install highline

[bashman]

Thanks for your help, I read it all ready but I will give it another look.

[bashman]

I changed line 816 and 817 from zabcon/zabbixapi.rb to:

zbx_api = ZbxAPI.new(http://x.x.x.x/zabbix)
zbx_api.login('admin','zabbix')

And zabcon.conf.default:

server=http://x.x.x.x/zabbix
username=admin
password=zabbix
lines=24
debug=0
language=english

But running ruby zabcon, I get this error message:

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': ./zabbixapi.rb:817: no .<digit> floating literal anymore; put 0 before dot (SyntaxError)
zbx_api = ZbxAPI.new(http://x.x.x.x/zabbix)
                                   ^

./zabbixapi.rb:817: syntax error, unexpected ')', expecting kEND        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'

        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
        from zabcon:32

Has anyone seen this before or knows how to solve this?

Thanks

[richlv]

hmm. it looks like we will need nelsonab here

[nelsonab]

Hmm, that's an odd error. There's a lot on my plate at the moment. I'll try and get some time later and see if I can reproduce it.

[bashman]

Thanks nelsonab for giving it a try. Take your time, and if you see anything please tell me.

[nelsonab]

Sorry for the delay, work has been busy.

Ok it looks like you've made a syntax error in your code change.

I should ask why you felt making the change was needed? It looks like your config file is appropriate.

[bashman]

I made the change because I want to use zabcon in a remote host instead of working on localhost Zabbix Server.

[nelsonab]

Understandable, you only need to change it in the config file, "zabcon.conf".

I think there is a statement to connect to local host in a unit test which is never called by the user. I should probably comment this appropriately.
