Unable to make any api call

[afang]

Hi all,

I'm trying to use the RESTful API in python, but I keep on getting this error: requests.exceptions.ConnectionError: ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer')).
I've done the following

Code: Select all

import requests

uri = "https://server-domain:9398/api/sessionMngr/?v=latest"
username = "..."
password = "..."
b64 = "..."
r = requests.get(uri, auth=(username, password), verify=False)
r = requests.get(uri, headers={'Authorization': f"Basic {b64}"}, verify=False)

When I try to go to the :9398/web page in Internet Explorer, I get an error: This page can't be displayed. Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting again.
Which I confirmed is already on.

Any leads would be helpful.
Thanks,
Allen

I believe the issue is that you're trying "get" when you need to be using "post"

Code: Select all

veeam_url = 'https://vbackup.lab.com:9398/api/'
user = "LAB\Administrator"
password = 'mysecretpassword'

veeam_session = requests.session()
rval = veeam_session.post(veeam_url+'/sessionMngr/?v=latest', auth=(user, password), verify=False)

Thanks for the reply, but I've modified my code but the error still persists. I've also tried

Code: Select all

r = requests.request("POST", ...)

and also tried a curl call

Code: Select all

curl -X POST -k -v -u username:password https://server-domain:9398/api/sessionMngr/?v=latest -H "Content-Length: 0"

which resulted in
* TLSv1.2 (OUT), TLS handshake, Client hello (1):
* OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to server-domain:9398
* stopped the pause stream!
* Closing connection 0
curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to server-domain:9398

Yep looks like it's changed since the old days when I wrote the script I pulled that code out of. Give something like this a go -

Code: Select all

import requests
import base64

user = 'VBR2019\Administrator'
password = '***'

eCreds = base64.b64encode(user+':'+password)
authHeader = {'Authorization': 'Basic ' + eCreds}

rval = requests.post('https://192.168.15.30:9398/api/sessionMngr/?v=latest', headers=authHeader, verify=False)
if (rval.status_code == 201):
    print('Session ID - ' + rval.headers['X-RestSvcSessionId'])
else:
    print('Error - ' + str(rval.status_code))

Took a few changes because b64encode() takes and spits out a bytes-like objects, but here it is and the 104 error is still here.

Code: Select all

uri = 'https://server-domain:9398/api/sessionMngr/?v=latest'
username = '...'
password = '...'
userpass = username + ':' + password
b64 = base64.b64encode(userpass.encode()).decode()
headers={'Authorization': 'Basic ' + b64}
r = requests.get(uri, headers=headers, verify=False)

Some research leads me to believe it could be an ssl issue on the server side(?) or something else, but I'm not too sure what specifically I could look around in the backup enterprise manager or the windows server it's on to help locate why exactly these api calls aren't being responded to.

[ronnmartin61]

Not sure however I'd suggest you try it with the single b64encode on your credentials as the second code snippet definitely works in my environment. Also (again) you need to post not "get" on the call...

Hi Allen,

Can you please confirm that server-domain in your URL is an Enterprise Manager server?

Code: Select all

uri = 'https://server-domain:9398/api/sessionMngr/?v=latest'

If you're trying to authenticate to the Veeam Backup & Replication RESTful API, a different port (9419) and corresponding API call should be used.

One method to validate the API is working correctly would be to test using their respective built-in web clients:

• Veeam Backup Enterprise Manager
• Veeam Backup & Replication

[afang]

Ah my mistake, I used the correct post call, but the error is still there.
The b64encode without encoding/decoding strings gives a TypeError: a bytes-like object is required, not 'str', and I have even tried placing a manually encoded string using base64encode.org in lieu of the function's output too.

I can confirm the server domain is correct, as I just used it to log onto the backup enterprise manager (the 9443 port), and checked the correct url in Configurations > About > Veeam RESTful API Service.
What I'm trying to get out of the api are the Reports (https://<Enterprise-Manager>:9398/api/reports/summary).

However one thing that is boggling is that the web client for the 9398 port can't be reached.

[chris.arceneaux]

Given that the web client is not functioning, I recommend you open a Veeam support case to further troubleshoot. Either there exists an issue with the RESTful API service or a firewall could be blocking access to the port.

Once you are able to successfully test the web client, here's working Python 3 sample code I just tested in my lab:

Code: Select all

import requests
import base64

username = '...'
password = '...'
userpass = username + ':' + password
b64 = base64.b64encode(userpass.encode()).decode()

url = "https://<enterpise-manager>:9398/api/sessionMngr/?v=latest"

headers = {'Authorization': 'Basic ' + b64}
response = requests.post(url, headers=headers, verify=False)

print(response.headers)

[afang]

Thanks, I opened a support case. It's number is 05252939.
I also looked into firewall rules for inbound/outbound connections. The predefined rules, Veeam RESTful API Service (HTTP-Out, HTTP-In, HTTPS-Out, HTTPS-In), are enabled and allowed for all connections on ports 9399 and 9398.

Thanks for sharing your case number Allen, I'll monitor it closely. Let's see what our engineers discover. Cheers!

Hi there,

Minor point but you can make your life a little easier by doiung the following:

from requests.auth import HTTPBasicAuth

auth = HTTPBasicAuth(username, password)

res = requests.post(self.login_url, auth=auth, verify=False)
