The strace (system call trace) and ltrace (library trace) commands can help you discover what a program attempts to do. These tools produce extraordinarily large amounts of output, but once you know what to look for, you’ll have more tools at your disposal for tracking down problems. stra...
Upon execution of the command, you will see the IP addresses or the hostname of several hops coming in between the source and destination. For each hop router, traceroute will float three time probes in milliseconds, which is the RTT to reach the router from the laptop. To trace the path...
1. Trace the Execution of an Executable You can use strace command to trace the execution of any executable. The following example shows the output of strace for the Linux ls command. $ strace ls execve("/bin/ls", ["ls"], [/* 21 vars */]) = 0 ...
traceroute-n<destination_IP> If you want to limit the number of hops, use the -m option along with the traceroute command: traceroute-mN<destination_IP> Here, put the desired number of hops in place of N. On execution, it will return only N number of hops in the results.The trace...

-S trace system calls as well as library calls. -t, -tt, -ttt print absolute timestamps. -T show the time spent inside each call. -u USERNAME run command with the userid, groupid of username. -V, --version output version information and exit. ...

The trace-cmd(1) record command will set up the Ftrace Linux kernel tracer to record the specified plugins or events that happen while the command executes. If no
