Standard ping tools can only tell you if a server is reachable. But what if you need to test specific services, monitor HTTP responses, or check if your email server is actually working? CryPing is a powerful command-line tool that extends standard ping functionality far beyond basic connectivity tests.
Difference Between CryPing and Standard Ping
The traditional ping tool uses ICMP (Internet Control Message Protocol) to check if a server is online. This is helpful to see if a server can be reached, but it doesn’t tell you if the services on that server are actually working.
CryPing works differently. This Windows tool can test specific services and protocols, giving you more detailed information about your network. Instead of just asking, “Is the server online?”, CryPing can tell you things like, “Is the web server working properly?” or “Can I connect to the email service?”

Monitoring and Alerting
CryPing comes with monitoring and alerting features to help you keep track of your network:
- Audible alarms when connections fail or succeed
- Timestamped output for logging purposes
- Continuous monitoring until manually stopped
Advanced Response Analysis
Unlike basic ping, CryPing can:
- Display full HTTP headers with the verbose flag
- Show specific HTTP status codes (200 OK, 404 Not Found, etc.)
- Provide detailed connection statistics
- Test specific web pages, not only server connectivity
How to Use CryPing with Examples
Basic Network Connectivity Testing
The simplest way to use CryPing is to test the network connection between your current PC and a remote device (usually another PC). You can specify the target by either its DNS name or its IP address.
Example: Pinging by DNS name
cmdCopyEditC:\>cryping www.example.com
CryPing - from www.example.com v1.6
Pinging www.example.com [93.184.216.34] with 32 bytes of data:Reply from 93.184.216.34: bytes=32 time=232ms TTL=248
Reply from 93.184.216.34: bytes=32 time=181ms TTL=248
Reply from 93.184.216.34: bytes=32 time=181ms TTL=248
Reply from 93.184.216.34: bytes=32 time=183ms TTL=248
Ping statistics for 93.184.216.34:
Requests: Sent = 4, Received = 4, Lost = 0 (0% loss)
Approximate round-trip times:
Minimum = 181ms, Maximum = 232ms, Average = 194ms
Example: Pinging by IP address
cmdCopyEditC:\>cryping 203.0.113.10
CryPing - from www.testserver.net v1.6
Pinging 203.0.113.10 [203.0.113.10] with 32 bytes of data:Reply from 203.0.113.10: bytes=32 time=180ms TTL=248
Reply from 203.0.113.10: bytes=32 time=180ms TTL=248
Reply from 203.0.113.10: bytes=32 time=180ms TTL=248
Reply from 203.0.113.10: bytes=32 time=182ms TTL=248
Ping statistics for 203.0.113.10:
Requests: Sent = 4, Received = 4, Lost = 0 (0% loss)
Approximate round-trip times:
Minimum = 180ms, Maximum = 182ms, Average = 181ms
If you can successfully ping a remote device by IP address but not by DNS name, this suggests a problem with DNS resolution.
If CryPing is unable to connect to the specified remote device, it could be due to one or more of the following reasons:
- No network connection exists between your PC and the remote device.
- The address you entered is incorrect (more likely when specifying an IP).
- The remote device is powered off.
- A firewall is blocking ping requests.
- A temporary network or internet issue is preventing connectivity.
Testing Web Server Responses with CryPing
CryPing can also test whether a web server is responding to HTTP requests. Use the -http flag to have CryPing connect using HTTP.
Example: HTTP Ping to a Web Server
cmdCopyEditC:\>cryping -http www.cryer.co.uk
CryPing - from www.example.com v1.6
Pinging www.example.com for HTTP status:Reply from www.example.com: 200 OK time=72ms
Reply from www.example.com: 200 OK time=42ms
Reply from www.example.com: 200 OK time=40ms
Reply from www.example.com: 200 OK time=39ms
HTTP ping statistics for www.example.com:
Requests: Sent = 4, Responses = 4, Lost = 0 (0% loss)
200 OK received 4 times (100%)
Approximate round-trip times:
Minimum = 39ms, Maximum = 72ms, Average = 48ms
Example: HTTP Ping to a Specific Page
You can also ping a specific page on the server. For example:
cmdCopyEditC:\>cryping -n 1 -http www.example.com/index.htm
CryPing - from www.example.com v1.6
Pinging www.example.com/index.htm for HTTP status:Reply from www.example.com/index.htm: 200 OK time=144ms
HTTP ping statistics for www.example.com/index.htm:
Requests: Sent = 1, Responses = 1, Lost = 0 (0% loss)
200 OK received 1 time (100%)
Approximate round-trip times:
Minimum = 144ms, Maximum = 144ms, Average = 144ms
Example: HTTP Ping to a Missing Page
If the requested page does not exist, the server will return an appropriate HTTP error code, such as 404 Not Found:
cmdCopyEditC:\>cryping -n 1 -http www.example.com/index
CryPing - from www.example.com v1.6
Pinging www.example.com/index for HTTP status:Reply from www.example.com/index: 404 Not Found time=58ms
HTTP ping statistics for www.example.com/index:
Requests: Sent = 1, Responses = 1, Lost = 0 (0% loss)
404 Not Found received 1 time (100%)
Approximate round-trip times:
Minimum = 58ms, Maximum = 58ms, Average = 58ms
Monitoring a Network Connection with Audible Alerts
CryPing can monitor a network connection for failures and sound an audible alarm (beep) when the connection is lost. This is useful for keeping an ear on critical connections without constantly watching the screen.
To enable this feature, use the -t and -alarm flags:
-tkeeps CryPing running continuously until stopped (press Ctrl+C to stop).-alarm(or-afor short) makes CryPing beep when a ping fails.
Example: Alert on Failure
C:\>cryping -t -alarm www.example.com
CryPing - from www.example.com v1.6 (build June 2010)
Pinging www.example.com[69.89.27.225] with 32 bytes of data:
Reply from 69.89.27.225: bytes=32 time=179ms TTL=248
Reply from 69.89.27.225: bytes=32 time=182ms TTL=248
Reply from 69.89.27.225: bytes=32 time=180ms TTL=248
...
If the network connection fails, your computer will emit a beep. Make sure your speakers or system sound are enabled to hear the alarm.
Inverting the Alert: Beep on Success
You can reverse this behavior, beep on success instead of failure using the -beep flag instead of -alarm. This is useful if you prefer a sound to confirm successful pings while staying silent on failure.
Example: Beep on Success
C:\>cryping -t -beep www.example.com
CryPing - from www.example.com v1.2 (build June 2010)
Pinging www.example.com [69.89.27.225] with 32 bytes of data:
Reply from 69.89.27.225: bytes=32 time=181ms TTL=248
...
With this setup, the computer beeps every time a ping succeeds.
Checking Connections to Specific Ports with CryPing
CryPing can also test connectivity to a specific port on a remote server. This is a simple and effective way to verify whether a service is listening and accepting connections on that port.
Example: Testing FTP Port (21)
Port 21 is commonly used by FTP servers. To check if a server is listening on port 21, use the -port flag followed by the port number:
C:\>cryping -port 21 www.example.com
CryPing - from www.cryer.co.uk v1.6 (build June 2010)
Pinging port 21 on www.example.com:
Successful connection to www.example.com port=21 time=201ms
Successful connection to www.example.com port=21 time=192ms
Successful connection to www.example.com port=21 time=199ms
Successful connection to www.example.com port=21 time=196ms
Ping port statistics for port 21 on www.example.com:
Requests: Made = 4, Successful = 4, Failed = 0 (0% loss)
Approximate round-trip times:
Minimum = 192ms, Maximum = 201ms, Average = 197ms
The output shows that connections to port 21 were successful, indicating an FTP service is running on the server.
Example: Testing VNC Port (5900)
Port 5900 is used by the popular VNC remote desktop service. To test if VNC is running on the server:
C:\>cryping -port 5900 www.example.com
CryPing - from www.example.com v1.6 (build June 2010)
Pinging port 5900 on www.example.com:
Failed to connect to www.example.com, port 5900
Failed to connect to www.example.com, port 5900
Failed to connect to www.example.com, port 5900
Failed to connect to www.example.com, port 5900
Ping port statistics for port 5900 on www.example.com:
Requests: Made = 4, Successful = 0, Failed = 4 (100% loss)
In this example, all attempts to connect to port 5900 failed, confirming that the VNC service is not running on the server.
By specifying a port with the -port option, you can quickly check whether a particular service is available and responsive on the target machine.
Testing Email Servers: SMTP and POP3
To fully test that an email server is operational, you should check both SMTP and POP3:
- SMTP is the protocol used to send email.
- POP3 is the protocol used to retrieve email.
CryPing lets you test each protocol individually, or both at the same time. The example below demonstrates how to check both protocols in a single command.
Example: Checking SMTP and POP3 Together
C:\>cryping -pop3 -smtp www.example.com
CryPing - from www.example.com v1.6 (build July 2010)
Pinging www.example.com for SMTP status:
Pinging www.example.com for POP3 status:
Reply from www.example.com: 220 Service ready time=0.90s
Reply from www.example.com: +OK Positive - Success time=374ms
Reply from www.example.com: 220 Service ready time=0.70s
Reply from www.example.com: +OK Positive - Success time=379ms
Reply from www.example.com: 220 Service ready time=0.87s
Reply from www.example.com: +OK Positive - Success time=382ms
Reply from www.example.com: 220 Service ready time=0.71s
Reply from www.example.com: +OK Positive - Success time=376ms
SMTP ping statistics for www.example.com:
Requests: Sent = 4, Responses = 4, Lost = 0 (0% loss)
220 Service ready received 4 times (100%)
Approximate round-trip times:
Minimum = 0.70s, Maximum = 0.90s, Average = 0.80s
POP3 ping statistics for www.example.com:
Requests: Sent = 4, Responses = 4, Lost = 0 (0% loss)
+OK Positive - Success received 4 times (100%)
Approximate round-trip times:
Minimum = 374ms, Maximum = 382ms, Average = 378ms
The output shows that both the SMTP and POP3 servers are responding correctly, with POP3 responding slightly faster than SMTP.
This feature of CryPing makes it easy to confirm the health and responsiveness of your email infrastructure.
If you’d like to see the full HTTP response headers when pinging a website, you can add the -v (verbose) flag along with -http. This can help you inspect server details, response metadata, and more.
Example: Displaying HTTP Headers
C:\>cryping -http -v -n 1 www.example.com
CryPing - from www.example.com v1.6
Pinging www.example.com for HTTP status:
Reply from www.example.com: 200 OK time=386ms
HTTP/1.1 200 OK
Date: Mon, 21 Jun 2010 12:51:55 GMT
Server: Apache/2.2.15 (CentOS) mod_ssl/2.2.15 0.9.8l DAV/2 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635
Last-Modified: Wed, 19 May 2010 17:44:16 GMT
Accept-Ranges: bytes
Content-Length: 8049
Connection: close
Content-Type: text/html
HTTP ping statistics for www.example.com:
Requests: Sent = 1, Responses = 1, Lost = 0 (0% loss)
200 OK received 1 time (100%)
Approximate round-trip times:
Minimum = 386ms, Maximum = 386ms, Average = 386ms
The verbose output includes standard HTTP headers such as Date, Server, Last-Modified, Content-Length, and Content-Type, providing valuable insight into the web server’s configuration and response.
