module.login(credentials) walks the list from get_credentials(). Each ID POSTs mode=191 to http://172.16.68.6:8090/httpclient.html with a 45 second timeout.

The portal returns XML. These <message> values skip the current ID and continue:

• Login failed. You have reached the maximum login limit.
• Your data transfer has been exceeded, Please contact the administrator

Success is You are signed in as {username}. That sets state.active_credential_index, sleeps two minutes, then tries check_internet_connection() and a speed test.

Anything else (unknown text, missing <message>, non-200) notifies and tries the next row. If the list ends with no success, login returns (True, cred_index) and the auto-login loop stops.

Order is SQLite SELECT username, password FROM credentials order, which follows id. Put the ID you want first at the top of the table.

CONNECTION_CHECK_INTERVAL = 90 in run_auto_login(). check_internet_connection() defaults to HTTP against https://www.google.com then https://www.cloudflare.com, 3 second timeout. First success returns True.

If that check fails, the loop calls module.login again. If it succeeds and fewer than 30 minutes have passed since last_login_time, it prints Internet is connected. No login needed. and sleeps 10 seconds.

There is a socket fallback in check_internet.py (8.8.8.8, 1.1.1.1, OpenDNS on port 53). The auto-login loop never passes method="socket". Only the module’s __main__ demo does.

FORCED_RELOGIN_INTERVAL = 30 * 60. The 30 minute timer is checked on the same 90 second tick as the HTTP probe. Connected plus stale session still triggers module.login. That is the keep-alive, not the two-minute sleep inside a successful login.

export_to_csv writes username,password with a header. Default path is credentials.csv in the database directory (~/.autologin_script/ on Unix).

import_from_csv maps columns case-insensitively. Accepted username headers:

• username
• userid (enrolment number) (the old CSV-based script)

Password column must be password. Duplicate usernames increment the skipped count and do not fail the whole import.

python autologin.py --import credentials.csv

send_notification(title, message):

• macOS: osascript display notification
• Linux: notify-send
• Windows: win10toast.ToastNotifier

Login, logout, daemon start/stop, and failures all go through this.

module.internet_speedtest.run_speed_test uses the speedtest package. --speedtest / menu 8 print download Mbps, upload Mbps, ping, and server. A successful portal login also runs a test after the two-minute wait, then folds those numbers into the “Connected” notification.

git clone https://github.com/tashifkhan/sophos-auto-login.git
cd sophos-auto-login
pip install -r requirements.txt
pip install pyinstaller

# macOS / Linux
pyinstaller --onefile --add-data "db/credentials.db:." autologin.py

# Windows
pyinstaller --onefile --add-data "db/credentials.db;." autologin.py

Output is dist/autologin (or autologin.exe). --add-data ships a seed DB. CredentialManger.get_db_path() copies it into the persistent path on first run of a frozen binary (sys.frozen).
