Herramientas para diagnósticos
Ping
USO: Ping nombre.dominio o dirección IP
Options:
•
-t Ping the specifed host until interrupted.
• -a Resolve addresses to hostnames.
• -n count Number of echo requests to send.
• -l size Send buffer size.
• -f Set Don't Fragment flag in packet.
• -i TTL Time To Live.
• -v TOS Type Of Service.
• -r count Record route for count hops.
• -s count Timestamp for count hops.
• -j host-list Loose source route along host-list.
• -k host-list Strict source route along host-list.
• -w timeout Timeout in milliseconds to wait for each reply.
Tracert
USO: Tracert nombre.dominio o dirección IP
Options:
• -d: Do not resolve addresses to hostnames.
• -h maximum_hops: Maximum number of hops to search for target.
• -j host-list: Loose source route along host-list.
• -w timeout: Wait timeout milliseconds for each reply.
Route
USO: Route Print
Sintaxis: ROUTE [-f] [command [destination] [MASK netmask] [gateway]]
•
-f : Clears the routing tables of all gateway entries. If this is used in conjunction
with one of the commands, the tables are cleared prior to running the command.
• command Specifies one of four commands
– PRINT Prints a route
– ADD Adds a route
– DELETE Deletes a route
– CHANGE Modifies an existing route
• Destination: Specifies the host to send command.
• MASK: If the MASK keyword is present, the next parameter is interpreted as the
netmask parameter.
•
netmask: If provided, specifies a sub-net mask value to be associated with this
route entry. If not specified, if defaults to 255.255.255.255.
• Gateway: Specifies gateway.
Netstat
Sintaxis: NETSTAT [-a] [-e] [-n] [-s] [-p proto] [-r] [interval]
-A
Displays all connections and listening ports. (Server-side
connections are normally not shown).
-E
Displays Ethernet statistics. This may be combined with the -s
option.
-N
Displays addresses and port numbers in numerical form.
-P proto
Shows connections for the protocol specified by proto; proto
May be tcp or udp. If used with the -s option to display
per-protocol statistics, proto may be tcp, udp, or ip.
-R
Displays the contents of the routing table.
-S
Displays per-protocol statistics. By default, statistics are
shown for TCP, UDP and IP; the -p option may be used to specify
A subset of the default.
interval
Redisplays selected statistics, pausing interval seconds
between each display. Press CTRL+C to stop redisplaying
statistics. If omitted, netstat will print the current
configuration information once.
Arp
ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr]
-a
Displays current ARP entries by interrogating the current
protocol data. If inet_addr is specified, the IP and Physical
addresses for only the specified computer are displayed. If
More than one network interface uses ARP, entries for each
ARP table are displayed.
-g
Same as -a.
inet_addr Specifies an internet address.
Arp Cont.
-N if_addr Displays the ARP entries for the network interface specified
by if_addr.
-D
Deletes the host specified by inet_addr.
-S
Adds the host and associates the Internet address inet_addr
with the Physical address eth_addr. The Physical address is
given as 6 hexadecimal bytes separated by hyphens. The entry
is permanent.
eth_addr
Specifies a physical address.
if_addr
If present, this specifies the Internet address of the
interface whose address translation table should be modified.
If not present, the first applicable interface will be used.
