[Help Required] Getting Certificate Error while starting Posh Server
manoj30 opened this issue · comments
I have installed latest PoshC2 on Kali Linux using below command.
curl -sSL https://raw.githubusercontent.com/nettitude/PoshC2/master/Install.sh | bash
I am getting below certificate error while running posh-server.
Traceback (most recent call last):
File "start.py", line 8, in <module>

File "/opt/PoshC2/poshc2/__init__.py", line 13, in run

File "/opt/PoshC2/poshc2/server/__init__.py", line 10, in start

File "/opt/PoshC2/poshc2/server/C2Server.py", line 754, in main
raise ValueError("Cannot find the certificate files")
ValueError: Cannot find the certificate files
Execution Environment
Kali Linux.
Could anyone please help me out here.
Code is trying to find out certificate and key files in /opt/PoshC2_Project.
Can we bypass this certificate check.
Hi,
Can you remove the project folder and start the server again.
e.g.
rm -rf /opt/PoshC2_Project.
posh-server or posh-service
Thanks for reply.
After deleting above folder, I've received below error.

I had received same error while running posh-server first time. (I re-ran posh-server and I got certificate issue)
I tried to google it. It seems csharp compiler package is not installed. I tried to find out the solution. But mono packages are not available.
It looks like some dependencies didn't successfully install. Are you running this in Kali or via Docker?
It might be worth running the install and checking any errors for packages.
I am using Kali VM.
I have tried to run Install.sh script from /opt/PoshC2 directory as a root.
I got below error but at the same time script went ahead and said
[+]Setup complete.
Output:
✔ Successfully created virtual environment!
Virtualenv location: /root/.local/share/virtualenvs/PoshC2-KGSTtxLR
✔ Success!

ERROR: Failed building wheel for psycopg2
Is it required to install psycopg2. (As setup said complete). I thought certificate issue is unrelated to this error.
So I asked about it.
psycopg2 is only required if you're using a Postgres database instead of the SQLite one, but if pip fails for one thing it bombs out and fails to install anything else after that which probably includes the openssl stuff required to create the certs.
Not sure why a pip install is failing on your host, you'd have to provide more info for that but for now if you're not using Postgres you can remove psycopg2 from requirements.txt and try running the install script again, see if we can just bypass the issue altogether...
Hi,
As Ben had pointed out that there could be dependencies issue, I downloaded and imported OVA file available on kali.org.
Now I am able to start server successsfully.
Thanks a lot.

FWIW this is the psycopg2 error:

Noted, thanks @wesinator , added a PR for this here: #147
Actually libpq-dev is already in the install file 🤔 which provides the libpq-fe.h header. @wesinator did your install script error at all?

Yea I noticed that which was odd
I don't remember I no longer have the output - I think that was the main error
