How to use tcpdump to capture packets in Linux and Solaris systems

Corresponding linux platform packet capture method to grasp the entire package: # tcpdump-X-s0host192.168.1.12 grasp 68 bytes: # tcpdump-Xhost192.168.1.12 corresponding port packet capture: # tcpdump-Xudpport1812 corresponding to the Solaris platform packet capture method # snoop-x0udpto192.168.1.28 # snoop Packet capture method for linux
Capture the entire package:
# Tcpdump-X-s 0 host 192.168.1.12
Capture 68 bytes:
# Tcpdump-X host 192.168.1.12
Corresponding port packet capture:
# Tcpdump-X udp port 1812

　　 Packet capture method on the corresponding Solaris platform
# Snoop-x 0 udp to 192.168.1.28
# Snoop-x 0 ucp from 192.168.1.28
# Snoop-x 0-t a-d eri udp port 1645
Capture packets by time:
# Snoop-x 0-t a-d hme1 from 192.168.1.28
Capture the package with the specified address and port and save it to the current log2 file:
# Snoop-x from 192.168.1.28 tcp 80> log2.log
Packet capture can also be placed in the background for automatic operation to prevent window close:
# Csh/first enter the csh environment/
# Nohup snoop-x 0-t a-d hme1 from 192.168.1.28> snoop. log &/& indicates running in the background/
