Hello
I just update LG to newlatest version and get amazing many errors :
Best Regards
TaKeN
I've noticed occasional broken images on some bgpmaps from the NLNOG RING LG, and upon deeper investigation some prefixes which contain longer AS-PATHs (usually those with multiple prepends) which are visible via significant chunks of the internet generate a very long bgpmap/?q={"....."} URL to the image generation script. I've seen some over 9500 characters.
An example of such a prefix. If you click the broken image link you'll likely get a HTTP 414 "Request URI too long" error.
Potential workaround to the problem:
Clicking the link to view the image full size could be a form submission and use POST, however I don't know how you'd go about solving that for the thumbnail that is currently linked to the full size image.
I'm curious, does anybody actually use memcached with bird-lg?
In my deployments, I patch it out because I don't want to add such a big service as dependency.
It seems to only cache the result of "AS to AS-name" lookups, used in the bgpmap. These lookups are made through DNS which already has a cache. So I think it makes sense to just remove all this memcached thing.
@sileht what was the original need for memcached? Did you run into rate-limiting issues with cymru?
Not sure this is really a problem but figured I'd mention it in case it wasn't expected/desired:
the multi-path bgpmap output gets rearranged visually with every run - sometimes the active path will be on the left, sometimes in the middle, sometimes on the right. Pressing Ctrl-R in the browser repeatedly shows the diagram bouncing around a bit.
It always appears to be correct, though.
This is as of commit 1a3c618522fd16e991d3877e1b714560aa095ff1.

Hello,
This is possible to add option to completly disable IPv4 or IPv6 ?
My friend use Your LG in environment where dont have IPv6 - but still IPv6 option is enable, I use in my environment only IPv6 ( lab ) and don
t have IPv4 - maybe please add option for select IPv4/IPv6 enable and what is default webpage?
Now default page is: return redirect("/summary/%s/ipv4" % "+".join(app.config["PROXY"].keys()))
so i get error everytime enter to webpage that`s why i change to:
return redirect("/summary/%s/ipv6" % "+".join(app.config["PROXY"].keys()))
Will be cool if You add option like this.
Thanks for Your work!
All the bgpmap queries return the following error in the logs, as well as an "Internal Server Error" on the frontend.
Please let me know if you need more informations.

it would be nice if one could query BIRD-LG over HTTP and get back the LG information in JSON format, instead of the regular (nice) HTML output.
This way I could easily integrate the BIRD-lg output in my existing applications and have them parse the data accordingly.
I recommend using pyparsing to parse the BIRD CLI output.
here is an example. I guess the fix there would be to implement a parser for the arguments to pass to whois before sending them off.
This isn't very high priority because it's executed as-is directly in whois (no shell), but if there's a vulnerability in whois it could potentially be abused (also I /guess/ the reply from whois is pasted directly in the page so it's a potential source of XSS if the whois server replies with something that will be executed, but I can't try that)
Hi,
I found an xss using the q parameter. This is the only parameter i tested, so there are probably other wholes.
http://.../prefix_bgpmap/gw+h3/ipv4?q=
If you need more info, let me know.
fyi: app return HTTP 500 when using two slash "/" in the q parameter. sanitize input before processing.

No matter what starting lg.py or lgproxy.py via flask run
always launches on 127.0.0.1:5000, overriding even hardcoded values in the source code. This violates POLA rather significantly.
Please document how to run the app under flask's development server, for those of us who aren't flask programmers.

Hi
I am running bird on a server to share our looking glass with our customers...this is just dedicated fr this purpose, and I'm using the same server to use for the bird-lg.
When installing, do i just edit the lg.cfg and lgproxy.cfg?
I am running lg.py and lgproxy.py but i get an error like below -
Failed retreive url: http://jnb.za.lg.wiocc.net:5000/traceroute?q=64.13.232.144
our bird is za.lg.wiocc.net
Cheers

There seems to be some interest in providing Docker images (#37, #72)
Several questions need discussion and/or help:
From the little knowledge I have of Docker, people seem to like passing configuration from an external source.
We can't really use env variables because the configuration has python objects. Maybe we could pass the config file to stdout of the python programs? I have no idea if gunicorn would allow this.
Flask has documentation about the different ways to configure it: https://flask.palletsprojects.com/en/1.1.x/config/ (nothing specific to Docker though)

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.
You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:
dump() shows all variables in the frame
dump(obj) dumps all that's known about the object

sileth has not been active on the project for several years. I have been doing some interim maintenance, but I can't commit to spend a lot of time on the project.
The situation is not really good at the moment, both on the community side:
and on the technical side:
bird-lg
to suit their needs, creating a lot of divergence and not contributing energy to the "main" projectThis calls for a "reboot" of the project, either by investing more maintenance energy to be able to transform it, or by re-designing / rewriting (parts of) the project from scratch.
In both cases, it requires a community of motivated people! If you are interested in such a "reboot", please reply to this ticket to discuss.
The following request shows standard javascript alert
/detail/aaa/ipv4?q=aaa"%3Balert(1)%2F%2F
in config file only used trace or ping command any my network set only ip address or router and gateway
How Can connect to the router (ssh or telnet)
To loockup route
of ip in cisco routers?
"show route for" query does not require selection of address family
must select the correct AFI
since AFI can be inferred from input (prefix/IP), there is no point to make AFI selection mandatory
I would to do a number of changes that would break compatibility with existing installations. Nothing bad, but configuration would need to be adapted. So we would need to do a "release" and communicate the changes.
For now I'm thinking about:
lg.cfg.example
and lgproxy.cfg.example
so that actual configuration files can be managed independently of the git repoIf you have other ideas for changes that would break compatibility, it's a good time so that we "release" everything at once.
We should definitely support python3 at this point...
Currently, the DOMAIN
configuration key is used for two completely different things:
myrouter
+ DOMAIN
)It would be good to introduce a new configuration variable like WEBSITE_TITLE
to avoid this second usage.
It is possible to use default values in the template for backwards compatibility:
{{ config.WEBSITE_TITLE|default("bird-lg looking glass") }}
Hello,
Please update Your README.mkd bird-lg need python-memcache too.
Best Regards!
When clicking on an AS number in the "route all" view, a WHOIS popup appears.
Default result for "whois AS[whatever]" contains source block informations (RIR delegation) with the following blocks prior to the targeted AS :
as-block:
organisation:
role:
role:
Usefull information starts at "% Information related to 'what your requested'"
Objects defined by the RPSL syntax could be folded by default, only the aut-num: object is relevant here.
When clicking on an AS number in the route all view, a popup shows with the aut-num:'s WHOIS record.
A nice addition would be to add a PeeringDB record to the popup's top bar.
PeeringDB offers a read-only access to users logged in as "guest / guest". The "participant" view can't be reached with a direct query based on the aut-num, the following querry has to be used :
The only result should be the targeted aut-num. No result means the aut-num has no peeringdb record.
Best approach could be to ask PeeringDB for an API to bypass guest login and access a participant's view straight from the aut-num. [email protected]
Because of the rise of RPKI validation among network operators, I thought it would be nice to show a route's validity state in BIRD-LG.
So I've added an API call to RIPE NCC's RPKI Validator (Example API URL) calls to lg.py
to show BGP origin validation states when displaying routes.
If there's interest for this to be in here, I'll create a pull request with my changes. It's not beautiful (code and output), so any hints to make it better are welcome. I'm fairly new to Python, so please be gentle.
So far, the API URL is hard coded and it's an external resource. But it could be changed to be configurable, so a local instance of the validator software can be accessed.
Hello
I just update bird-lg to new version and stop working.

I got version from 2019 year and working perfect with BIRD 1.6.6
Hi,
are there any docker images for bird-lg?
I just installed and configured bird 2.0.2 and bird-lg, so this may be an issue with my config. I am running bird, lgproxy.py, and lg.py on the same host. I'm using the current master branch (1f0efca) for bird-lg.
I can successfully query the proxy via curl:
$ curl http://localhost:5001/bird?q=show%20protocols
Name Proto Table State Since Info
peer1 BGP --- up 13:04:05.471 Established
However, on the show protocols page of the looking glass (e.g. http://lg.example.com:5000/summary/lg/ipv4) the table contains only the header and one empty row.
The log in /var/log/lg.log
contains a new entry every time I try to reload the show protocols page in the looking glass:
couldn't parse: peer1 BGP --- up 13:04:05.471 Established
It looks like the issue is that the table column, '---', doesn't match the regular expression.
I do see that vpn4tab is populated:
$ sudo /usr/local/sbin/birdc show route count
BIRD v2.0.2 ready.
0 of 0 routes for 0 networks in table master4
0 of 0 routes for 0 networks in table master6
9581 of 9581 routes for 9581 networks in table vpntab4
Total: 9581 of 9581 routes for 9581 networks in 3 tables
I'm guessing that the table is showing '---' because there are other tables (master4 and master6) present? I'm not sure if bird-lg should be able to handle this, or if my bird configuration needs to somehow exclude the master4 and master6 tables.
My bird.conf
file is below:
log syslog { debug, trace, info, remote, warning, error, auth, fatal, bug };
log stderr all;
router id 127.0.0.1;
vpn4 table vpntab4;
vpn6 table vpntab6;
protocol bgp peer1 {
local as 65321;
neighbor 192.168.1.1 as 65321;
hold time 180;
vpn4 mpls {
import all;
export all;
};
vpn6 mpls {
import all;
export all;
};
}
When clicking on an AS number in the route all view, a popup shows with the aut-num:'s WHOIS record.
A nice addition would be to add a ROBTEX link to the popup's top bar.
Links to ROBTEX' AS view has the following syntax : http://as.robtex.com/as[number].html.
Robtex doesn't support AS32, only 16bit AS are linkable as of 2013-04.
When trying to call show_bgpmap, I have the following crash from pydot.
How can I get dump why this crash happen ?

We need an API for bird-lg. It would allow to better separate the web UI and the backend, and allow external tools to query bird-lg.
This is about a public API that would be exposed by bird-lg, and not about router <--> bird-lg
communication (routers should not expose a publicly-available interface anyway)
The API should:
https://(domain)/prefix/(node)/ipv4?q=%22%2balert(document.domain)%2b%22
Example from the domain: https://(domain)/prefix/(node)/ipv4?q=%22%2balert(document.domain)%2b%22
Arbitrary Javascript Code alert(document.domain)
is executed.
This can leverage to leak cookies, or even run malicious code on the victim's browser.
There are cases where path can be None and extend ise used on it.
Here is a quick patch about it:
