21 The B<rxdebug> command provides a trace of Rx activity for the server or
22 client machine named by the B<-servers> argument. Rx is AFS's proprietary
23 remote procedure call (RPC) protocol, so this command enables the issuer
24 to check the status of communication between the Cache Manager or an AFS
25 server process (as specified with the B<-port> argument) on the machine
26 and one or more processes on other machines.
32 =item B<-servers> <I<server machine>>
34 Specifies the machine that is running the Cache Manager or server process
35 for which to trace Rx activity. Provide the machine's IP address in dotted
36 decimal format, its fully qualified host name (for example,
37 C<fs1.abc.com>), or the shortest abbreviated form of its host name that
38 distinguishes it from other machines. Successful use of an abbreviated
39 form depends on the availability of a name resolution service (such as the
40 Domain Name Service or a local host table) at the time the command is
43 =item B<-port> <I<IP port>>
45 Specifies the process for which to trace Rx activity. Omit this argument
46 to specify the File Server (B<fileserver> process), or provide one of the
51 =item C<7000> for the File Server (B<fileserver> process)
53 =item C<7001> for the Cache Manager (specifically, its callback interface)
55 =item C<7002> for the Protection Server (B<ptserver> process)
57 =item C<7003> for the Volume Location (VL) Server (B<vlserver> process)
59 =item C<7004> for the Authentication Server (B<kaserver> process)
61 =item C<7005> for the Volume Server (B<volserver> process)
63 =item C<7007> for the BOS Server (B<bosserver> process)
65 =item C<7008> for the Update Server (B<upserver> process)
67 =item C<7009> for the NFS/AFS Translator's B<rmtsysd> daemon
69 =item C<7021> for the Backup Server (B<buserver> process)
73 Finally, specify C<7025> through C<65535> for the Backup Tape Coordinator
74 (B<butc> process) that has the port offset number derived by subtracting
79 Produces output only for connections that are not in dally mode.
81 =item B<-allconnections>
83 Produces output for all connections, even inactive ones. By default, the
84 output includes information only for connections that are active or in
85 dally mode when the B<rxdebug> command is issued.
89 Produces detailed statistics about Rx history and performance (for
90 example, counts of the number of packets of various types the process has
91 read and sent, calculations of average and minimum roundtrip time, and so
96 Produces output only for connections in which the process designated by
97 the B<-port> argument is acting as the server.
101 Produces output only for connections in which the process designated by
102 the B<-port> argument is acting as the client.
104 =item B<-onlyport> <I<port>>
106 Produces output only for connections between the process designated by the
107 B<-port> argument and the specified port on any another machine. Use the
108 same port identifiers as for the B<-port> argument.
110 =item B<-onlyhost> <I<host>>
112 Produces output only for connections between the process designated by the
113 B<-port> argument and any process on the specified machine. To identify
114 the machine, use the same notation as for the B<-servers> argument.
118 Produces output only for connections that are using the specified
119 authentication level. Provide one of the following values:
125 Cconnections at authentication level rxkad_auth
129 Connections at authentication level rxkad_clear
133 Connections at authentication level rxkad_crypt
137 Unauthenticated connections (equivalents are C<null>, C<noauth>, and
144 Reports the AFS build level of the binary file for the process designated
145 by the B<-port> argument (or of the kernel extensions file for port 7001,
146 the Cache Manager's callback interface). Any other options combined with
147 this one are ignored.
151 Produces only the standard statistics that begin the output produced by
152 every option (other than B<-version>), without reporting on any
153 connections. Any other options combined with this one are ignored.
157 Outputs information from the I<peer structure> maintained for each port on
158 another machine to which the process designated by the B<-port> argument
159 has a connection. There is information about roundtrip time and numbers of
160 packets sent and received, for example.
164 Prints the online help for this command. All other valid options are
171 If any options other than B<-version> or B<-help> are provided, the output
172 written to the standard output stream begins with basic statistics about
173 packet usage and availability, how many calls are waiting for a thread,
174 how many threads are free, and so on (this is the only information
175 provided by the B<-noconns> flag). Adding other options produces
176 additional information as described in L<OPTIONS>. The output is intended
177 for debugging purposes and is meaningful to someone familiar with the
178 implementation of Rx.
