Ping hosts using tcp packets.
A Python version is also available.
Simple example:
$ tcping example.org Pinging example.org 4 times on port 80: Reply from 93.184.216.34:80 time=1.72 ms Reply from 93.184.216.34:80 time=1.81 ms Reply from 93.184.216.34:80 time=1.75 ms Reply from 93.184.216.34:80 time=1.77 ms Statistics: -------------------------- Host: example.org Sent: 4 packets Received: 4 packets Lost: 0 packets (0.00%) Min latency: 1.72 ms Max latency: 1.81 ms Average latency: 1.76 ms
Using nimble:
$ nimble install tcping
On Linux, a link to the resulting binary will be usually created at: "~/.nimble/bin/tcping".
To enable it "system wide" just copy the binary to "/usr/local/bin":
$ cp ~/.nimble/bin/tcping /usr/local/bin
Using nim compiler:
Since only the standard library is used, just download the single source code file and compile it:
$ wget https://raw.githubusercontent.com/pdrb/tcping/master/src/tcping.nim $ nim c -d:release tcping.nim
Using compiler to create a size optimized binary:
$ nim c -d:release --opt:size --passL:-s tcping.nim
We can reduce the binary size even more using UPX:
$ upx --best tcping
After these steps, the resulting binary size is 35K on my Linux server.
Usage: tcping host [options] ping hosts using tcp packets, e.g., 'tcping example.org' Options: -v, --version show program's version number and exit -h, --help show this help message and exit -t ping host until stopped with 'control-c' -n:count number of requests to send (default: 4) -p:port port number to use (default: 80) -w:timeout timeout in milliseconds to wait for reply (default: 3000)
Ping host on port 80 (default):
$ tcping host
Ping host on port 22:
$ tcping host -p:22
Ping host 10 times with 1 second timeout:
$ tcping host -n:10 -w:1000
