Further to the above query and the reply from Hartmut, I did as he suggested and issued the command "vos listaddr -cell XXX" for all cells in the CellServDB file on the system in question. This generated a large file (as expected) which included quote a lot if entries for the network 192.168.*; I understand that this network segment is defined as being non-routable so are there a number of sites which should have NetRestrict or NetInfo files but do not, or is there some other explanation ? 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) Jonathan Wheeler e-Science Centre Rutherford Appleton Laboratory _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
