Policy Manual - Control files and their fields. [ previous ] [ Contents ] [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ] [ 6 ] [ 7 ] [ 8 ] [ 9 ] [ 10 ] [ 11 ] [ 12 ] [ A ] [ B ] [ C ] [ D ] [ E ] [ F ] [ G ] [ next ] The package management system manipulates data represented in a common format, known as control data, stored in control files. Control files are used for source packages, binary packages and the .changes files which control the installation of uploaded files[31]. 5.1 Syntax of control files A control file consists of one or more paragraphs of fields[32]. The paragraphs are separated by empty lines. Parsers may accept lines consisting solely of spaces and tabs as paragraph separators, but control files should use empty lines. Some control files allow only one paragraph; others allow several, in which case each paragraph usually refers to a different package. Each paragraph consists of a series of data fields.

The field ends at the end of the line or at the end of the last continuation line (see below). Package: libc6 simple folded multiline.

Judd Vinet. Synopsis knockd [options] Description knockd is a port-knock server. It listens to all traffic on an ethernet (or PPP) interface, looking for special "knock" sequences of port-hits. A client makes these port-hits by sending a TCP (or UDP) packet to a port on the server. This port need not be open -- since knockd listens at the link-layer level, it sees all traffic even if it's destined for a closed port. When the server detects a specific sequence of port-hits, it runs a command defined in its configuration file. Download Options -i, --interface <int> Specify an interface to listen on. -d, --daemon Become a daemon. -c, --config <file> Specify an alternate location for the config file. -D, --debug Ouput debugging messages.

-l, --lookup Lookup DNS names for log entries. -v, --verbose Output verbose status messages. -V, --version Display the version. -h, --help Syntax help. Configuration knockd reads all knock/event sets from a configuration file. Example #1: This example uses two knocks. Example #2: Author. [1] Linux admins: some quick questions. : sysadmin.

Using Samba to shutdown windows from Linux terminal [Archive] I would like to mention some simi-progress I have made on this subject. I have a remote system I'm SSHed into. It's an Ubuntu Server 7.10 box and therefore doesn't have any sort of GUI (and hence no capability to access Remote Desktop). I have a windows box which I use as a wifi AP on the same network linking a desktop without wifi to the internet.

To recap: Redeemer, laptop with wifi running ICS on Windows Server 2003 Nautilus, laptop using ethernet with Ubuntu Server 7.10 and ssh, SAMBA. Only system accessable from internet. Enlightened, desktop running Thunderbird & Windows Server 2003, using Redeemer to get online. My problem is that Thunderbird on Enlightened accesses GMail over POP3 once every minute. Here the problem begins. I can SSH to Nautilus with no problem, but telnet is not open on Redeemer and I have no other method to access it right now. My first breakthrough was when I discovered that you MUST provide a hostname argument, EVEN IF you specify an IP address. Any thoughts?

PXE Booting. Syslog. There are hundreds of Linux applications on the market, each with their own configuration files and help pages. This variety makes Linux vibrant, but it also makes Linux system administration daunting. Fortunately, in most cases, Linux applications use the syslog utility to export all their errors and status messages to files located in the /var/log directory. This can be invaluable in correlating the timing and causes of related events on your system. It is also important to know that applications frequently don't display errors on the screen, but will usually log them somewhere.

Knowing the precise message that accompanies an error can be vital in researching malfunctions in product manuals, online documentation, and Web searches. syslog, and the logrotate utility that cleans up log files, are both relatively easy to configure but they frequently don't get their fair share of coverage in most texts. The first describes the function (facility) of the application that generated it. . *. *.
