Hi,

Hi

I do this simple lab :

[Kali].66}----(10.12.0.0/16)---{.1[Router]

The osp config of Router is :

router ospf 1
   network 10.12.0.0 0.0.255.255 area 0

The Hello of the attack of Loki stays on state : "LOADING"

If i use the network 10.10.0.0/16, the Hello finishs to state "FULL"
If i use the file "module_ospf.py" from loki_0.2.7-1, the Hello finishs to state "FULL"

Hi Raizo,

Thanks for the stuff. Just to let you know, you should add python-ipy to the "Local packages" folder.

It works perfectly then.

Hi @0xc0decafe

Can we have access to the source code of loki_0.3.0-r502-1 ? (i think to C code of asleap, bf, mplsred, ...)

Thanks

Hi, I was trying to associate with a VyOS OSPF router in my lab, but couldn't get things to work (stuck in "2-WAY" state).

After some time searching, I checked the vyos logs (cat /var/log/messages | grep ospf), and found this after the Loki hello packets :

T-bit on, drop it.

Looking on Google gave absolutely no result, so I had to compare manually an hello packet forwarded by VyOS with the one sent by Loki.

I noticed that the VyOS ones didn't have the Multi-Topology Routing bit set, in contrary to Loki. I am not an OSPF expert, and cannot explain exactly what it is doing, so here is the doc : https://sites.google.com/site/amitsciscozone/ospf/multi-topology-routing-in-ospf

After exploring the Loki code, I located the line where this bit is set :

OPTION_TOS_CAPABILITY = 0x1

As a simple fix, I put this value to 0 :

sed -i 's:OPTION_TOS_CAPABILITY = 0x1:OPTION_TOS_CAPABILITY = 0x0:g' /usr/share/loki/modules/module_ospf.py

And now it works, I have a "FULL" state to my VyOS router !

I don't know if this bit is only used by a certain type of routers (e.g. Cisco), but it definitely made Loki unable to associate. My VyOS had the simplest config possible, so it may be possible to enable this feature (although I can't seem to find how in the doc).

I look forward to hear about a possible fix, like an auto detection for example (or if you are already aware of this behaviour).

edit : After spending a bit of time looking at the code, I noticed that there can't be a simple fix for this, as a lot of configuration differences (hello interval, dead interval) on remote router makes the pair process impossible.

First of all I would like to thank you for the great work. Unfortunately the cracking of data does not work for me. The following message appears:

Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner

File "/usr/share/loki/modules/module_ospf.py", line 1093, in run

Thanks for your help.
