Some cells may want/need to broadcast both the private and public addresses for their servers if the cell is located behind a NAT. The interesting output would be the list of cells which are doing so. It is possible that not everyone realizes that they are publishing private addresses. > Here is output from the command "tcpdump 192.168.67.1": > > 11:57:02.587157 lcg0329.gridpp.rl.ac.uk.afs3-callback > > 192.168.67.1.afs3-fileserver: rx data fs call get-time (32) (DF) > 11:57:04.647085 lcg0329.gridpp.rl.ac.uk.afs3-callback > > 192.168.67.1.afs3-fileserver: rx ack (65) (DF) > 11:57:05.667117 lcg0329.gridpp.rl.ac.uk.afs3-callback > > 192.168.67.1.afs3-fileserver: rx data fs call get-time (32) (DF) > 11:57:07.707266 lcg0329.gridpp.rl.ac.uk.afs3-callback > > 192.168.67.1.afs3-fileserver: rx ack (65) (DF) > 11:57:09.237138 lcg0329.gridpp.rl.ac.uk.afs3-callback > > 192.168.67.1.afs3-fileserver: rx data fs call get-time (32) (DF) This is simply an indication that the AFS client has been given the IP address of a file server and the client is checking periodically to see if that file server is currently available.
