I am trying to do rysnc a 4G file to another directory and want to capture rsync packets using tcpdump. I tried listning to port 873 which is used for rsync but did not find anything captured. I checked the config file , it says rsync is using port 873 only. Am i missing anything here ? IS there any better approach to do that ?
tcpdump -n -vv "port 873" tcpdump: WARNING: eth0: no IPv4 address assigned tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 0 packets captured 0 packets received by filter 0 packets dropped by kernel
