Command lines in Windows
September 11, 2018 |
Some cases, we can use command lines so that open tools, access system,... where we cannot open by GUI in windows or linux OS.
I. Command lines in Windows
1. Open Remote Desktop Connection
Typing the flowing command line below:
C:\Users\<user_name>> mstsc
How to check port of Remote Desktop:
1. Open regedit
2. Go to Navigate to the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
3. find PortNumber
4. You can edit port and restart Remote Desktop Services.
4. You can edit port and restart Remote Desktop Services.
Typing the flowing command line below:
C:\Users\<user_name>> ssms
3. Open other command line window with administator user.
Typing the flowing command line below:
C:\Users\<user_name>> runas /user:Administrator cmd
and then enter password.
4. Restart a Windows service
net stop workstation
net start workstation
With the command line, we can resolve the issue:
"Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed".
5. "Netstat" command line.
Netstart command is used show TCP/IP port in windows. We can use for check port which program is using or not.
Displays protocol statistics and current TCP/IP network connections.
NETSTAT [-a] [-b] [-e] [-f] [-n] [-o] [-p proto] [-r] [-s] [-t] [interval]
-a Displays all connections and listening ports.
-b Displays the executable involved in creating each connection or
listening port. In some cases well-known executables host
multiple independent components, and in these cases the
sequence of components involved in creating the connection
or listening port is displayed. In this case the executable
name is in [] at the bottom, on top is the component it called,
and so forth until TCP/IP was reached. Note that this option
can be time-consuming and will fail unless you have sufficient
permissions.
-e Displays Ethernet statistics. This may be combined with the -s
option.
-f Displays Fully Qualified Domain Names (FQDN) for foreign
addresses.
-n Displays addresses and port numbers in numerical form.
-o Displays the owning process ID associated with each connection.
-p proto Shows connections for the protocol specified by proto; proto
may be any of: TCP, UDP, TCPv6, or UDPv6. If used with the -s
option to display per-protocol statistics, proto may be any of:
IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.
-r Displays the routing table.
-s Displays per-protocol statistics. By default, statistics are
shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;
the -p option may be used to specify a subset of the default.
-t Displays the current connection offload state.
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.
Example:
netstat -ab
netstat -aon
