Does your connection drop when idle, or do you need to know the moment a website or mail server stops responding? Connection Keeper keeps idle sessions alive and checks that online services respond. The program can also monitor websites, DNS records, FTP files, and mail servers, with alerts when a check fails.
Connection Keeper sends activity to prevent idle disconnects
For session maintenance, Connection Keeper can request a real web address or a placeholder URL at intervals. Set a fixed interval or let the timing vary randomly; the real-address list is editable. This activity is intended to keep a connection from being dropped for inactivity.
The program can wait while offline and begin its work once a connection becomes available. It can also try to restore a dropped dial-up line and close prompts asking whether to stay online. Popup handling includes simulated input and other methods, including terminating the window.
Monitor websites, DNS, FTP, and mail services
Connection Keeper verifies that web pages, DNS entries, FTP downloads and incoming or outgoing mail servers are working. It can also look for a domain in DNS blacklists, check whether a webpage still links to a specified site, and verify HTTP redirects.
When a check detects an error, the program can show a popup or send an email. It can also launch a command line when a problem occurs, allowing an administrator to connect an alert to a custom notification or logging task.
Run checks from the command line
Command-line options can check whether a file exists or download a webpage and report errors. These checks can run during computer startup, so a problem with network access or a monitored site can be surfaced without opening the main window. The program can run quietly from the notification area.
