DESCRIPTION
The rxdebug command provides a trace of Rx activity for the server or
client machine named by the -servers 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 -port argument) on the
machine and one or more processes on other machines.
OPTIONS-servers <server machine>
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, "fs1.abc.com"), 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.
-port <IP port>
Specifies the process for which to trace Rx activity. Omit this
argument to specify the File Server (fileserver process), or
provide one of the following values:
7000 for the File Server (fileserver process)
7001 for the Cache Manager (specifically, its callback interface)
7002 for the Protection Server (ptserver process)
7003 for the Volume Location (VL) Server (vlserver process)
7004 for the Authentication Server (kaserver process)
7005 for the Volume Server (volserver process)
7007 for the BOS Server (bosserver process)
7008 for the Update Server (upserver process)
7009 for the NFS/AFS Translator's rmtsysd daemon
7021 for the Backup Server (buserver process)
Finally, specify 7025 through 65535 for the Backup Tape Coordinator
(butc process) that has the port offset number derived by
subtracting 7025 from this value.
-nodally
Produces output only for connections that are not in dally mode.
-allconnections
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 rxdebug command is issued.
-rxstats
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).
-onlyserver
Produces output only for connections in which the process
designated by the -port argument is acting as the server.
-onlyclient
Produces output only for connections in which the process
designated by the -port argument is acting as the client.
-onlyport <port>
Produces output only for connections between the process designated
by the -port argument and the specified port on any another
machine. Use the same port identifiers as for the -port argument.
-onlyhost <host>
Produces output only for connections between the process designated
by the -port argument and any process on the specified machine. To
identify the machine, use the same notation as for the -servers
argument.
-onlyauth
Produces output only for connections that are using the specified
authentication level. Provide one of the following values:
auth
Connections at authentication level rxkad_auth
clear
Connections at authentication level rxkad_clear
crypt
Connections at authentication level rxkad_crypt
none
Unauthenticated connections (equivalents are "null", "noauth",
and "unauth")
-version
Reports the AFS build level of the binary file for the process
designated by the -port 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.
-noconns
Produces only the standard statistics that begin the output
produced by every option (other than -version), without reporting
on any connections. Any other options combined with this one are
ignored.
-peers
Outputs information from the peer structure maintained for each
port on another machine to which the process designated by the
-port argument has a connection. There is information about
roundtrip time and numbers of packets sent and received, for
example.
-help
Prints the online help for this command. All other valid options
are ignored.
OUTPUT
If any options other than -version or -help 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 -noconns flag). Adding other options
produces additional information as described in OPTIONS. The output is
intended for debugging purposes and is meaningful to someone familiar
with the implementation of Rx.
EXAMPLES
The following command shows Rx statistics on the server 192.168.1.100:
% rxdebug 192.168.1.100
Trying 192.168.1.100 (port 7000):
Free packets: 265, packet reclaims: 0, calls: 0, used FDs: 34
not waiting for packets.
0 calls waiting for a thread
11 threads are idle
Done.
The following command shows the OpenAFS version running on the server
192.168.1.100:
% rxdebug 192.168.1.100 -version
Trying 192.168.1.100 (port 7000):
AFS version: OpenAFS 1.4.2fc2 built 2006-08-31
PRIVILEGE REQUIRED
None.
