ldapsearch	LDAP search allows querying LDAP server for objects.
Host	LDAP server IP address.
Login	Login of the user allowed to browse the directory.
Password	Password of the user allowed to browse the directory.
Domain	Directory domain to query.
Filter	Objects filtering parameter.
Attributes	LDAP search attributes.

Ping	Ping sends a sequence of 10 ICMP packets to selected host.
Numeric output only	Does not resolve host’s IP address to its mnemonic name.
Record route	Enables tracking packets’ route.

netcat	`netcat` allows establishing connection with remote host on specified port number.

host	`host` is used to determine if the DNS server correctly resolves mnemonic hostnames.

traceroute	`traceroute` allows for determining packets’ route between Fudo PAM and the specified host.
Do not resolve hop addresses	Subsequent hop IP addresses are not resolved to mnemonic names.
Use ICMP ECHO instead of UDP datagrams	Enforces `traceroute` to use UDP packets instead of ICMP.
Firewall evasion mode	Enforces the same port numbers for UDP and TCP packets. Target port is not incremented with each packet sent.
Set the “don’t fragment” bit	Disables packet fragmentation in case the packet exceeds defined MTU (Maximum Transmission Unit) value defined for the network. Exceeding the MTU value results in an error.
