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.
