Is connection possible without ping request

I have a question which is conceptual in nature, is it possible to receive traffic from a remote host to my host machine even if the ping from host to remote machine is not happening in Linux( Red Hat).

I hope my question is clear that is it possible for a connection to happen from a host to remote machine even if it is not pinging from host to remote machine in Red Hat Linux.

Requesting a reply to my query.

Regards

rsh(1c) 																   rsh(1c)

Name
       rsh - remote shell

Syntax
       rsh host [-l username] [-n] command
       host [-l username] [-n] command

Description
       The  command  connects to the specified host, and executes the specified command.  The command copies its standard input to the remote com-
       mand, the standard output of the remote command to its standard output, and the standard error of the remote command to its standard error.
       Interrupt, quit and terminate signals are propagated to the remote command.  The command normally terminates when the remote command does.

       The  remote  username  used is the same as your local username, unless you specify a different remote name with the -l option.  This remote
       name must be equivalent, in the sense of to the originating account.  No provision is made for specifying a password with a command.

       If you omit command, then instead of executing a single command, you are logged in on the remote host using

       Shell metacharacters which are not quoted are interpreted on local machine, while quoted  metacharacters  are  interpreted  on  the  remote
       machine.  Thus the command

	  rsh otherhost cat remotefile >> localfile

       appends the remote file remotefile to the localfile localfile, while

	  rsh otherhost cat remotefile ">>" otherremotefile

       appends remotefile to otherremotefile.

       Host  names are given in the file Each host has one standard name (the first name given in the file), which is rather long and unambiguous,
       and optionally one or more nicknames.  The host names for local machines are also commands in the directory If you put  this  directory	in
       your search path then the can be omitted.

Options
       -l username	   Logs you in as the specified user, not as your user login name.

       -n		   Redirects all command input to

Restrictions
       The  command  is  confused by output generated by commands in a .cshrc file on the remote host.	In particular, `where are you?' and `stty:
       Can't assign requested address' are messages which can result if output is generated by the startup file.

       If you are using and put a in the background without redirecting its input away from the terminal, it blocks even if no reads are posted by
       the remote command.  If no input is desired you should redirect the input of to using the -n option.

       You cannot run an interactive command like Use

       Stop signals stop the local process only.

Files
       /etc/hosts
       /usr/hosts/*
