@krolingo I just make some improvement on zabbix-ipsec script (the most part of then, identation). Can you check if is working know?

Hi,

Thank you @alanwds for this work, I find it really useful and well done.

Maybe this issue is resolved since then, but I encountered the same problem.

Here are the modifications I made for the zabbix-ipsec.py script to work again after the tunnels name has been changed from connxxxx to conx, and for the description to be well displayed :

• line 8, ensure that the variable IPSEC_CONF points to the new path : IPSEC_CONF = '/var/etc/ipsec/swanctl.conf'

• line 61 in the parseConf() function, edit the regex for the reg_conn variable : from re.compile('^conn\s((?!%default).*)') to reg_conn = re.compile('^\s*con[0-9]')

• I added the following variable to fetch the IPSEC VPN description (line 65 for me) :
  reg_descr = re.compile('(?<=# P1 (ikeid [0-9]): ).*')

• line 89 for me, after

if m2:
right_tmp.append(m2)

I added the following operations :
descr_tmp = list()
m3 = re.search(reg_descr, g)
m3 = m3.group(0)
if m3:
descr_tmp.append(m3)

• And finally line 98 for me, the new data variable is populated with the description : data[conn_tmp[0]] = [left_tmp[0], right_tmp[0], descr_tmp[0]]
  I attached the edited version of zabbix-ipsec.py to this reply, hope someone will find this useful!
