ABCDEFGHIJKLMNOPQRSTUVWXYZ


adjtimex

Read and optionally set system timebase parameters.

adjtimex [-q] [-o offset] [-f frequency] [-p timeconstant] [-t tick]

        -q              Quiet
        -o offset       Time offset, microseconds
        -f frequency    Frequency adjust, integer kernel units (65536 is 1ppm)
                        (positive values make clock run faster)
        -t tick         Microseconds per tick, usually 10000
        -p timeconstant
Example

The following example shows how to read the system timebase parameters.

# adjtimex
    mode:         0
-o  offset:       0
-f  frequency:    0
    maxerror:     16384000
    esterror:     16384000
    status:       64 ( UNSYNC )
-p  timeconstant: 2
    precision:    1
    tolerance:    33554432
-t  tick:         10000
    time.tv_sec:  1437045938
    time.tv_usec: 201954
    return value: 5 (clock not synchronized)

arp

Manipulate ARP cache.

arp  
[-vn] [-H type] [-i if] -a [hostname]  
[-v] [-i if] -d hostname [pub]  
[-v] [-H type] [-i if] -s hostname hw_addr [temp]  
[-v] [-H type] [-i if] -s hostname hw_addr [netmask nm] pub  
[-v] [-H type] [-i if] -Ds hostname ifa [netmask nm] pub 

        -a              Display (all) hosts
        -s              Set new ARP entry
        -d              Delete a specified entry
        -v              Verbose
        -n              Don't resolve names
        -i IF           Network interface
        -D              Read  from given device
        -A, -p AF       Protocol family
        -H HWTYPE       Hardware address type
Example

The following example shows how to display the ARP table.

# arp -a
router.example.com (192.168.1.1) at 24:A4:3C:3C:80:00 [ether]  on br0
unifi.example.com (192.168.1.10) at B8:27:EB:A7:30:00 [ether]  on br0
server.example.com (192.168.1.20) at 00:15:5D:52:70:00 [ether]  on br0
? (192.168.1.100) at D0:67:E5:38:10:00 [ether]  on br0

        -q              Quiet
        -b              Keep broadcasting, don't go unicast
        -D              Duplicated address detection mode
        -U              Unsolicited ARP mode, update your neighbors
        -A              ARP answer mode, update your neighbors
        -c N            Stop after sending N ARP requests
        -w timeout      Time to wait for ARP reply, in seconds
        -I dev          Interface to use (default eth0)
        -s sender       Sender IP address
        target          Target IP address


ash
