<P><STRONG>Description</STRONG>
|
|
<P>The <B>rxdebug</B> command provides a trace of Rx activity for the
|
|
server or client machine named by the <B>-servers</B> argument. Rx
|
|
is AFS's proprietary remote procedure call (RPC) protocol, so this
|
|
command enables the issuer to check the status of communication between the
|
|
Cache Manager or an AFS server process (as specified with the <B>-port</B>
|
|
argument) on the machine and one or more processes on other machines.
|
|
<P><STRONG>Options</STRONG>
|
|
<DL>
|
|
<P><DT><B>-servers
|
|
</B><DD>Specifies the machine that is running the Cache Manager or server process
|
|
for which to trace Rx activity. Provide the machine's IP address
|
|
in dotted decimal format, its fully qualified host name (for example,
|
|
<B>fs1.abc.com</B>), or the shortest abbreviated form of its
|
|
host name that distinguishes it from other machines. Successful use of
|
|
an abbreviated form depends on the availability of a name resolution service
|
|
(such as the Domain Name Service or a local host table) at the time the
|
|
command is issued.
|
|
<P><DT><B>-port
|
|
</B><DD>Specifies the process for which to trace Rx activity. Omit this
|
|
argument to specify the File Server (<B>fileserver</B> process), or
|
|
provide one of the following values:
|
|
<DL>
|
|
<DD><P><B>7000</B> for the File Server (<B>fileserver</B> process)
|
|
<DD><P><B>7001</B> for the Cache Manager (specifically, its callback
|
|
interface)
|
|
<DD><P><B>7002</B> for the Protection Server (<B>ptserver</B> process)
|
|
<DD><P><B>7003</B> for the Volume Location (VL) Server (<B>vlserver</B>
|
|
process)
|
|
<DD><P><B>7004</B> for the Authentication Server (<B>kaserver</B>
|
|
process)
|
|
<DD><P><B>7005</B> for the Volume Server (<B>volserver</B> process)
|
|
<DD><P><B>7007</B> for the BOS Server (<B>bosserver</B> process)
|
|
<DD><P><B>7008</B> for the Update Server (<B>upserver</B> process)
|
|
<DD><P><B>7009</B> for the NFS/AFS Translator's <B>rmtsysd</B>
|
|
daemon
|
|
<DD><P><B>7021</B> for the Backup Server (<B>buserver</B> process)
|
|
<DD><P><B>7025</B> through <B>65535</B> for the Backup Tape Coordinator
|
|
(<B>butc</B> process) that has the port offset number derived by
|
|
subtracting 7025 from this value
|
|
</DL>
|
|
<P><DT><B>-nodally
|
|
</B><DD>Produces output only for connections that are not in dally mode.
|
|
<P><DT><B>-allconnections
|
|
</B><DD>Produces output for all connections, even inactive ones. By
|
|
default, the output includes information only for connections that are active
|
|
or in dally mode when the <B>rxdebug</B> command is issued.
|
|
<P><DT><B>-rxstats
|
|
</B><DD>Produces detailed statistics about Rx history and performance (for
|
|
example, counts of the number of packets of various types the process has read
|
|
and sent, calculations of average and minimum roundtrip time, and so
|
|
on).
|
|
<P><DT><B>-onlyserver
|
|
</B><DD>Produces output only for connections in which the process designated by
|
|
the <B>-port</B> argument is acting as the server.
|
|
<P><DT><B>-onlyclient
|
|
</B><DD>Produces output only for connections in which the process designated by
|
|
the <B>-port</B> argument is acting as the client.
|
|
<P><DT><B>-onlyport
|
|
</B><DD>Produces output only for connections between the process designated by the
|
|
<B>-port</B> argument and the specified port on any another
|
|
machine. Use the same port identifiers as for the <B>-port</B>
|
|
argument.
|
|
<P><DT><B>-onlyhost
|
|
</B><DD>Produces output only for connections between the process designated by the
|
|
<B>-port</B> argument and any process on the specified machine. To
|
|
identify the machine, use the same notation as for the <B>-servers</B>
|
|
argument.
|
|
<P><DT><B>-onlyauth
|
|
</B><DD>Produces output only for connections that are using the specified
|
|
authentication level. Provide one of the following values:
|
|
<UL>
|
|
<P><LI><B>auth</B> for connections at authentication level
|
|
<B>rxkad_auth</B>
|
|
<P><LI><B>clear</B> for connections at authentication level
|
|
<B>rxkad_clear</B>
|
|
<P><LI><B>crypt</B> for connections at authentication level
|
|
<B>rxkad_crypt</B>
|
|
<P><LI><B>none</B> for unauthenticated connections (equivalents are
|
|
<B>null</B>, <B>noauth</B>, and <B>unauth</B>)
|
|
</UL>
|
|
<P><DT><B>-version
|
|
</B><DD>Reports the AFS build level of the binary file for the process designated
|
|
by the <B>-port</B> argument (or of the kernel extensions file for port
|
|
7001, the Cache Manager's callback interface). Any other options
|
|
combined with this one are ignored.
|
|
<P><DT><B>-noconns
|
|
</B><DD>Produces only the standard statistics that begin the output produced by
|
|
every option (other than <B>-version</B>), without reporting on any
|
|
connections. Any other options combined with this one are
|
|
ignored.
|
|
<P><DT><B>-peers
|
|
</B><DD>Outputs information from the <I>peer structure</I> maintained for each
|
|
port on another machine to which the process designated by the
|
|
<B>-port</B> argument has a connection. There is information about
|
|
roundtrip time and numbers of packets sent and received, for example.
|
|
<P><DT><B>-help
|
|
</B><DD>Prints the online help for this command. All other valid options
|
|
are ignored.
|
|
</DL>
|
|
<P><STRONG>Output</STRONG>
|
|
<P>If any options other than <B>-version</B> or <B>-help</B> are
|
|
provided, the output written to the standard output stream begins with basic
|
|
statistics about packet usage and availability, how many calls are waiting for
|
|
a thread, how many threads are free, and so on (this is the only information
|
|
provided by the <B>-noconns</B> flag). Adding other options
|
|
produces additional information as described in the preceding
|
|
<B>Options</B> section of this reference page. The output is
|
|
intended for debugging purposes and is meaningful to someone familiar with the
|
|
implementation of Rx.
