SSLrdist -DFn -c name ... [login@]host[:dest]
SSLrdist -z cert=cert_file ...
SSLrdist -V
The -c option forces SSLrdist to interpret the remaining arguments as a small distfile. The equivalent distfile is as follows.
( name ... ) -> [login@]host
install [dest] ;
SSLrdist uses
ssl_rcmd(3) function call to access each target host (via a proxy if need
be. See
ssl_rcmd(3) for details.) Except if the target host is the string
localhost and the remote user name is the same as the local user name,
SSLrdist will run the command
/bin/sh -c rdistd -S
On each target host SSLrdist
will attempt to run the command
rdistd -S
<rdistd path> -S
The -l logopts option to SSLrdist tells SSLrdist what logging options to use locally. The -L logopts option to SSLrdist tells SSLrdist what logging options to pass to the remote rdistd server.
The form of logopts should be of form
facility=types:facility=types...
The valid facility names are:
- stdout
- Messages to standard output.
- file
- Log to a file. To specify the file name, use the format ``file=filename=types''. e.g. ``file=/tmp/rdist.log=all,debug''.
- syslog
- Use the syslogd(8) facility.
- notify
- Use the internal rdist notify facility. This facility is used in conjunction with the notify keyword in a distfile to specify what messages are mailed to the notify address.
types should be a comma separated list of message types. Each message type specified enables that message level. This is unlike the syslog(3) system facility which uses an ascending order scheme. The following are the valid types:
- change
- Things that change. This includes files that are installed or updated in some way.
- info
- General information.
- notice
- General info about things that change. This includes things like making directories which are needed in order to install a specific target, but which are not explicitly specified in the distfile.
- nerror
- Normal errors that are not fatal.
- ferror
- Fatal errors.
- warning
- Warnings about errors which are not as serious as nerror type messages.
- debug
- Debugging information.
- all
- All but debug messages.
Here is a sample
command line option:
-l stdout=all:syslog=change,notice:file=/tmp/rdist.log=all
The distfile contains a sequence of entries that specify the files to be copied, the destination hosts, and what operations to perform to do the updating. Each entry has one of the following formats.
<variable name> `=' <name list>
[ label: ] <source list> `->' <destination list> <command list>
[ label: ] <source list> `::' <time_stamp file> <command list>
The first format is used for defining variables. The second format is used for distributing files to other hosts. The third format is used for making lists of files that have been changed since some given date. The source list specifies a list of files and/or directories on the local host which are to be used as the master copy for distribution. The destination list is the list of hosts to which these files are to be copied. Each file in the source list is added to a list of changes if the file is out of date on the host which is being updated (second format) or the file is newer than the time stamp file (third format).
Labels are optional. They are used to identify a command for partial updates.
Newlines, tabs, and blanks are only used as separators and are otherwise ignored. Comments begin with `#' and end with a newline.
Variables to be expanded begin with `$' followed by one character or a name enclosed in curly braces (see the examples at the end).
The source and destination lists have the following format:
<name>
or
`(' <zero or more names separated by white-space>
`)'
These simple lists can be modified by using one level of set addition, subtraction, or intersection like this:
list '-' list
or
list '+' list
or
list '&' list
If additional modifications are needed (e.g., ``all servers and client machines except for the OSF/1 machines'') then the list will have to be explicitly constructed in steps using "temporary" variables.
The shell meta-characters `[', `]', `{', `}', `*', and `?' are recognized and expanded (on the local host only) in the same way as csh(1). They can be escaped with a backslash. The `~' character is also expanded in the same way as csh but is expanded separately on the local and destination hosts. When the -owhole option is used with a file name that begins with `~', everything except the home directory is appended to the destination name. File names which do not begin with `/' or `~' use the destination user's home directory as the root directory for the rest of the file name.
The command list consists of zero or more commands of the following format.
`install' <options> opt_dest_name `;'
`notify' <name list> `;'
`except' <name list> `;'
`except_pat' <pattern list> `;'
`special' <name list> string `;'
`cmdspecial' <name list> string `;'
The install command is used to copy out of date files and/or directories. Each source file is copied to each host in the destination list. Directories are recursively copied in the same way. Opt_dest_name is an optional parameter to rename files. If no install command appears in the command list or the destination name is not specified, the source file name is used. Directories in the path name will be created if they do not exist on the remote host. The -o distopts option as specified above under OPTIONS, has the same semantics as on the command line except they only apply to the files in the source list. The login name used on the destination host is the same as the local host unless the destination name is of the format ``login@host".
The notify command is used to mail the list of files updated (and any errors that may have occurred) to the listed names. If no `@' appears in the name, the destination host is appended to the name (e.g., name1@host, name2@host, ...).
The except command is used to update all of the files in the source list except for the files listed in name list. This is usually used to copy everything in a directory except certain files.
The except_pat command is like the except command except that pattern list is a list of regular expressions (see ed(1) for details). If one of the patterns matches some string within a file name, that file will be ignored. Note that since `\' is a quote character, it must be doubled to become part of the regular expression. Variables are expanded in pattern list but not shell file pattern matching characters. To include a `$', it must be escaped with `\'.
The special command is used to specify sh(1) commands that are to be executed on the remote host after the file in name list is updated or installed. If the name list is omitted then the shell commands will be executed for every file updated or installed. String starts and ends with `"' and can cross multiple lines in distfile. Multiple commands to the shell should be separated by `;'. Commands are executed in the user's home directory on the host being updated. The special command can be used to rebuild private databases, etc. after a program has been updated. The following environment variables are set for each special command:
The cmdspecial command is similar to the special command, except it is executed only when the entire command is completed instead of after each file is updated. The list of files is placed in the environment variable $FILES. Each file name in $FILES is separated by a `:' (colon).
If a hostname ends in a ``+'' (plus sign), then the plus is stripped off and NFS checks are disabled. This is equivalent to disabling the -ochknfs option just for this one host.
The following is a small example.
HOSTS = ( matisse root@arpa)
FILES = ( /bin /lib /usr/bin /usr/games
/usr/include/{*.h,{stand,sys,vax*,pascal,machine}/*.h}
/usr/lib /usr/man/man? /usr/ucb /usr/local/rdist )
EXLIB = ( Mail.rc aliases aliases.dir aliases.pag crontab dshrc
sendmail.cf sendmail.fc sendmail.hf sendmail.st uucp vfont )
${FILES} -> ${HOSTS}
install -oremove,chknfs ;
except /usr/lib/${EXLIB} ;
except /usr/games/lib ;
special /usr/lib/sendmail "/usr/lib/sendmail -bz" ;
srcs:
/usr/src/bin -> arpa
except_pat ( \\.o\$ /SCCS\$ ) ;
IMAGEN = (ips dviimp catdvi)
imagen:
/usr/local/${IMAGEN} -> arpa
install /usr/local/lib ;
notify ralph ;
${FILES} :: stamp.cory
notify root@cory ;
distfile - input command
file
$TMPDIR/rdist* - temporary file for update lists
If the basename of a file (the last component in the pathname) is ".", then SSLrdist assumes the remote (destination) name is a directory. i.e. /tmp/. means that /tmp should be a directory on the remote host.
The following options are still recognized for backwards compatibility:
-v -N -O -q -b -r -R -s -w -y -h -i -x
Variable expansion only works for name lists; there should be a general macro facility.
SSLrdist aborts on files which have a negative mtime (before Jan 1, 1970).
If a hardlinked file is listed more than once in the same target, then SSLrdist will report missing links. Only one instance of a link should be listed in each target.
