ngrep strives to provide most of GNU grep's common features, applying them to the network layer.
ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal
expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP,
UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces,
and understands BPF filter logic in the same fashion as more common packet sniffing tools,
such as tcpdump and snoop.

SSH (Secure Shell) is a program for logging into and executing commands
on a remote machine. It is intended to replace rsh (rlogin and rsh) and
provides openssl (secure encrypted communication) between two untrusted
hosts over an insecure network.

xorg-x11 (X Window System) connections and arbitrary TCP/IP ports can
also be forwarded over the secure channel.

SSH (Secure Shell) is a program for logging into a remote machine and
for executing commands on a remote machine. This package contains a
GNOME-based passphrase dialog for OpenSSH.
