21 pwmd \- a universal data server
24 [options] [file1] [...]
28 is a daemon/server that serves clients data which is stored in an, optionally
29 encrypted and compressed, XML data file. Clients connect and send commands
30 that either retrieve or store data.
33 The following are the available command line options. Remaining arguments are
34 files to add to the cache on startup.
36 .I "\-\-rcfile, \-f rcfile"
37 Specify an alternate configuration file. The default is \fB~/.pwmd/config\fR.
40 .I "\-\-import, \-I filename \-\-outfile filename"
41 Imports an XML file. The XML file should be in conformance to the pwmd DTD.
42 See COMMANDS contained in the distributed pwmd archive for details. If
43 encryption is wanted (specified with the \fBiterations\fP configuration
44 parameter or the \fI\-\-iterations\fP command line switch), you will be
45 prompted for a passphrase to encrypt with. The output is written to the
46 filename specified with the \fI\-\-outfile\fP command line switch which should
47 then be placed in the configured \fBdata_directory\fP.
50 .I "\-\-iterations, \-i iterations
51 The number of encryption iterations to use when importing. When not specified,
52 the \fBiterations\fP configuration option from the \fBglobal\fP section will
56 .I "\-\-key\-file, \-k keyfile"
57 When importing (\fI\-\-import\fP) or converting (\fI\-\-convert\fP), obtain
58 the key from the specified filename. Only the first line is read from this
59 file. Be sure to set \fBkey_file\fP in your configuration.
62 .I "\-\-convert, \-C filename \-\-outfile filename"
63 Converts a \fBpwmd\fP version 1 data file to a version 2 data file. If
64 encrypted, you will be prompted for a passphrase to use for decryption (unless
65 using a \fI\-\-key-file\fP). The converted data file will be saved to the
66 filename specified with the \fI\-\-outfile\fP command line switch and with the
67 same passphrase and iterations as the version 1 data file.
70 .I "\-\-disable\-dump, \-D"
71 Disable the XPATH, LIST and DUMP protocol commands. This overrides any
72 \fBdisable_list_and_dump\fP configuration parameter.
75 .I "\-\-no\-fork, \-n"
76 Run as a foreground process.
79 .I "\-\-no\-pinentry, \-P"
82 use overriding any configuration setting.
92 .SH CONFIGURATION FILE
93 Blank lines and lines beginning with '#' are ignored. Some options can have
94 data file-specific settings by placing them in a file section. A file section
95 is declared by surrounding the filename with braces (i.e., \fI[filename]\fP).
96 Global options may be specified in a \fI[global]\fP section and are the
97 default options for new or unspecified files. If the first character of a
98 string value is a tilde, it will be expanded to your home directory. First the
101 .I "socket_path=<string>"
102 Listen on the specified socket. The default is \fI~/.pwmd/socket\fR.
105 .I "socket_perms=<integer>"
106 Permissions to set after creating the socket. This will override any
111 .I "data_directory=<string>"
114 should store and retrieve data files. The default is \fI~/.pwmd/data\fR.
117 .I "disable_mlockall=<boolean>"
118 When set to \fBfalse\fP,
120 will be called after the client connects. This will use more physical memory
121 but may also be more secure. Most will probably find it overkill since the
122 contents of all allocated memory is cleared before being freed. Note that this
123 doesn't affect the file cache which is always stored in RAM (if possible).
126 .I "log_path=<string>"
127 Logs informational messages to the specified file. The default is
131 .I "enable_logging=<boolean>"
132 Enable or disable logging to \fIlog_path\fR. The default is \fBfalse\fR.
135 .I "syslog=<boolean>"
138 with facility LOG_DAEMON and priority LOG_INFO. The default is \fBfalse\fR.
141 .I "log_level=<integer>"
142 The logging level. When \fB0\fP, only connections and errors are logged. When
143 \fB1\fP, client commands are also logged. When \fB2\fP, the command arguments
144 are also logged. The default is \fB0\fP.
147 .I "disable_list_and_dump=<boolean>"
148 When \fBtrue\fP, the \fBXPATH\fP, \fBLIST\fP and \fBDUMP\fP protocol commands
149 will be disabled and will return an error code.
152 .I "cache_push=<list>"
153 A list of filenames separated with commas that will be pushed into the file
156 will prompt for the key for each file specified unless the key was specified
157 with the \fIkey\fR or \fIkey_file\fR parameters in a matching file section.
161 .I "priority=<integer>"
162 The priority, or niceness, of the server. The default is inherited from the
166 Below are options that can be specified in the \fB[global]\fP or
167 \fB[filename]\fP section. If in both then \fB[filename]\fP will have
170 .I "backup=<boolean>"
171 Whether to create a backup of the data file when saving. The default is
172 \fBtrue\fP. The backup filename has the .backup extension appended to the
176 .I "cache_timeout=<integer>"
177 The number of seconds to keep the cache entry for this file. If \fB-1\fP, the
178 cache entry is kept forever. If \fB0\fP, each time the file is opened (if
179 encrypted) or saved a key will be required.
182 .I "enable_pinentry=<boolean>"
183 If \fBfalse\fP, disable the use of
185 When disabled and a file requires a passphrase, the passphrase must be
186 included in the command (see COMMANDS included in the archive). The default is
187 \fBtrue\fP. Also see \fBPINENTRY\fP below.
190 .I "pinentry_path=<string>"
191 The full path of the pinentry binary. The default is specified at compile
195 .I "pinentry_timeout=<integer>"
196 The number of seconds before the pinentry dialog will terminate while waiting
197 for a passphrase. The default is \fB20\fP. Set to \fB0\fP to wait forever.
200 .I "iterations=<integer>"
201 The number of times to encrypt the data. A value of 10000 or more will make
202 dictionary attacks very slow depending on the CPU and size of the data file.
203 The default is \fB1\fP iteration. Setting to \fB0\fP will disable encryption.
207 The default cipher to use when saving a data file. Valid values are:
208 \fBaes128\fP, \fBaes192\fP, \fBaes256\fP, \fBserpent128\fP, \fBserpent192\fP,
209 \fBserpent256\fP, \fBcamellia128\fP, \fBcamellia192\fP, \fBcamellia256\fP,
210 \fB3des\fP, \fBcast5\fP, \fBblowfish\fP, \fBtwofish128\fP and
211 \fBtwofish256\fP. The default is \fBaes256\fP.
214 .I "iteration_progress=<integer>"
215 After the specified number of iterations have been processed while encrypting
216 or decrypting, a status message with the keyword \fBPROGRESS\fP will be sent
217 to the client. Setting to \fB0\fP, the default, disables sending these
221 .I "xfer_progress=<integer>"
222 Commands that send data lines to the client can send the XFER status message
223 after the specified number of bytes have been sent. The number of bytes is
224 rounded to ASSUAN_LINELENGTH (1002).
228 The initial passphrase to use for this file. If specified in the
229 \fBglobal\fP section then "\fBglobal\fP" is treated as a data filename and
230 not a default for other files. Note that if a client changes the passphrase
231 for this data file with the \fBSAVE\fP command, then this value is not
232 modified and will need to be updated by hand.
235 .I "key_file=<string>"
236 Same as the \fBkey\fP option above but obtains the key from the specified
237 filename with the key being on the first line of the file. Note that if the
238 cache entry for this file gets removed then the only way to have it added
239 again is to restart \fBpwmd\fP or to re-read the configuration file (i.e., you
240 won't be prompted from pinentry).
243 .I "compression_level=<integer>"
244 The default compression level for data files from \fB1\fP to \fB9\fP, \fB1\fP
245 being the fastest but least compression and \fB9\fP being the slowest but best
246 compression. To disable compression entirely, set to \fB0\fP. The default is
250 .I "zlib_bufsize=<integer>"
251 The input and output buffer size when compressing and decompressing. This
252 affects how often the COMPRESS and DECOMPRESS status messages are sent and
253 also affects compression quality. The default is \fB65536\fP. Set to a higher
254 value for larger files.
257 .I "recursion_depth=<integer>"
258 The maximum number of times to resolve a target attribute for a single element
259 in an element path. An error is returned when this value is exceeded. The
260 default is \fB20\fP but can be disabled by setting to \fB0\fP.
263 .I "keepalive=<integer>"
264 Sends keep alive status messages to the client every N seconds. Set to \fB0\fP
265 to disable (not recommended). The default is \fB30\fP.
269 When \fBenable_pinentry\fP is \fBtrue\fP, commands that require a key
272 to retrieve the passphrase. Since \fBpwmd\fP is normally a daemon process, it
273 isn't attached to any terminal. So \fBpinentry\fP needs to know where to put
274 it's dialog box by using command line options when executed. These can be set
275 by either using protocol commands (see COMMANDS included in the archive) or by
276 creating a file \fI~/.pwmd/pinentry.conf\fP. When using this file, each line
277 should contain NAME=VALUE pairs where NAME is one of:
280 The full path of the tty device.
284 The terminal type (i.e., vt100). Must be set when \fBTTYNAME\fP is set.
288 If using an X11 pinentry.
292 For internationalization.
296 For internationalization.
300 The full path to the pinentry binary. The default is \fI@pinentry@\fP.
303 The file is read only once after each client first connects. Note that if your
304 not using a \fBDISPLAY\fP, then both \fBTTYNAME\fP and \fBTTYTYPE\fP should be
305 set otherwise you'll get a segfault from ncurses.
310 Clears the entire file cache. If there are any clients connected, a key will
311 be required for the next \fBOPEN\fP or \fBSAVE\fP command.
314 Reloads the configuration file.
316 .B SIGTERM and SIGINT
317 Disallows new connections and waits for all clients to disconnect before
323 Default configuration file.
326 Default data directory.
329 Default listening socket.
332 Default log file when logging is enabled.
335 Default location of the pinentry binary.
337 .B ~/.pwmd/pinentry.conf
338 Default pinentry settings for new clients.
