[Bug 1540807] Re: ArpON ver. 2.7: the DARPI and -d (--darpi) flag bug.

 

Change package to arpon.

** Package changed: linux (Ubuntu) => arpon (Ubuntu)

** Description changed:

  Hello. Because on Ubuntu 12.04 LTS an ArpON package is pretty outdated
  (ver. 2.0-2.1 0) I've decided to use a version from a Vivid release -
  2.7.
  
  It seems that ArpON ver. 2.7 has a bug related to a DARPI anti Arp
  Poisoning techniques. Because I am using a DHCP method to obtain an IP
  address I needed to use a DARPI method (Dynamin Arp Inspect.) instead of
  SARPI (Static Arp Inspect). After installation via 'apt-get' utility,
  configuring "arpon" file from '/etc/default/' directory and uncomment
  line responsible for a DARPI method, ArpON failed to start with a
  following error:
  
  $ sudo /etc/init.d/arpon start
  * Starting anti ARP poisoning daemon arpon
  20:38:55 PID = </var/run/arpon.pid>
  
  /usr/bin/arpon: invalid  option -- 'd'          [fail]
  
- For a DARPI method line in the '/etc/default/arpon' file looks this way:
- DAEMON_OPTS="-q -f /var/log/arpon/arpon.log -g -d". According to the
- Ubuntu manpage[1] '-g' flag stands for "Works in logging mode", since
- '-d' flag means "Manages Arp Cache dynamically". Everything should work
- okay, but it does not. I've tried many possibilities, configurations
- etc.

  arpon is [OK]. Here are some technical details:

-    Release:	12.04
+    Description:	Ubuntu 12.04.5 LTS
+    Release:	12.04

  By the way: ArpON sometimes crashed with "SIGSEGV in pthread_kill()"
  (after user login), but I will have to create a new bug report.
