My favourite TCP commands

Console commands

Display VIPA stuff

Netstat

Netstat has two formats TSO and OMVS

  • TSO format is like NETSTAT CONN (can also be issued from operator console)
  • OMVS format is like netstat -c

There is a comparison table here

The omvs command is good for netstat -c > filename

TSO command

  1. netstat conn Displays the information about each active TCP connection and UDP socket
  2. netstat conn ( PORT 10443 who is using port 10443 Gives Foreign socket 10.1.0.2..48518 (see below)
  3. netstat allconn Provides information for all TCP connections and UDP sockets, including recently closed ones.
  4. netstat allconn ( ipport 10.1.0.2+48518 Show information about this socket coming in from 10.1.0.2 port 48518
  5. netstat all ( ipport 10.1.0.2+48518 shows all information about the remote port.
  6. netstat conn TCP TCPIP2 for TSO command for TCPIP stack TCPIP2
  7. netstat home give the IP addresses this TCPIP stack uses. For example 10.1.1.2 amd 127.0.0.1
  8. netstat Dev give stats about all interfaces
  9. netstat home report dsn ‘colin.output’ issue the home command, and write the output to ‘colin.output’

  2. netstat -c -P 10443 who is using port 10443 Gives Foreign socket 10.1.0.2..48518 (see below)
  3. netstat -a Provides information for all TCP connections and UDP sockets, including recently closed ones.
  4. netstat -a -B 10.1.0.2+48518 Show information about this socket coming in from 10.1.0.2 port 48518
  5. netstat -A -B 10.1.0.2+48518 shows all information about the remote port.
  6. netstat -c -p TCPIP2 display all connections for TCPIP jobname TCPIP2
  7. netstat -c -p TCPIP2 -P 10443 which jobs are using port 10443 – direct the request to TCPIP2 stack
  8. netstat -h give the IP addresses this TCPIP stack uses. For example 10.1.1.2 amd 127.0.0.1
