I've built a news site using SimplePie to pull in a set of feeds and display them on a page. The caching is working but the problem is that the first initial load is slow. After that, you can hit refresh and it loads very quickly. I'd like to eliminate that first slow load by creating a cronjob, which is what I've heard many other people do. I'm very new to crons and programming in general so hopefully someone can help me understand this.
I found one example of a guy using the following cron to automatically visit his page and he syncronized the cache duration, thus eliminating any slow starts:
The problem I found was that my host doesn't support wget (or lynx, or ssh) so I've been trying to write a cron that will achieve the same results but using either curl or php. Here is what I have so far:
Again, I found these examples from reading other resources so I'm not entirely sure what they're doing or if they're correct for my situation. I've also set the cache duration to match at 15 minutes. When I run either the curl or php cron above, in my e-mail I receive the entire html source for the specified index.php. I'm assuming this means they're working correctly, but still my news page has that initial slow load. I'm open to any thoughts or ideas. Thanks in advance.
I am running SCO on a Netfinity system and two crons are started on bootup, but only after the system is brought down hard. i.e. running haltsys, reboot, or by a power outage. Has anyone seen this before and know a resolution to stop it? (0 Replies)
Im on an OS X 10.4 Mac server running bind 9.3, I just replaced the entire network with cisco hardware, all machines including servers now have private ip addresses that t he firewall resolves.

Hi
There are few crons running under my account. How to check the last run time of the Cron and if it has run successfully without any errors.
Also if there are any errors while running, will the errors be stored some where?
How to check the status of all the Crons?
Thanks

I have googled around a bit and could not find an answer to how this works:

Buddies, cron is not executing any monitoring scripts for 'Oracle' user in Red Hat Linux 5.

buffchan
BUFFCHAN(8) System Manager's Manual BUFFCHAN(8)NAME
buffchan - buffered file-writing backend for InterNetNews
SYNOPSIS
buffchan [ -b ] [ -c lines ] [ -C seconds ] [ -d directory ] [ -f fields ] [ -m map ] [ -p pidfile ] [ -l lines ] [ -L seconds ] [ -r ] [
-s file_format ] [ -u ]
DESCRIPTION
Buffchan reads lines from standard input and copies certain fields in each line into files named by other fields within the line. Buffchan
is intended to be called by innd(8) as an exploder feed.
OPTIONS -b Once buffchan opens a file it keeps it open. The input must therefore never specify more files than can the number of available
descriptors can keep open. If the ``-b'' flag is used, the program will allocate a buffer and attach it to the file using set-
buf(3).
-c If the ``-c'' flag is used with a number n, then buffchan will close, and re-open, a file after every n lines are written to a file.
-C Similarly, the ``-C'' flag may be used to specify that all files should be closed and re-opened every n seconds.
-d The ``-d'' flag may be used to specify a directory the program should change to before starting. If this flag is used, then the
default for the ``-s'' flag is changed to be a simple ``%s.''
-f Buffchan input is interpreted as a set of lines. Each line contains a fixed number of initial fields, followed by a variable number
of filename fields. All fields in a line are separated by whitespace. The default number of initial fields is one; the ``-f'' flag
may be used to specify a different number of fields. See filechan(8) for an example.
-p If the ``-p'' flag is used, the program will write a line containing its process ID (in text) to the specified file.
-l If the ``-l'' flag is used with a number n, then buffchan will call fflush(3) after every n lines are written to a file.
-L If the ``-L'' flag is used with a number n, then all files will be flushed every n seconds.
-r By default, the program sets its standard error to /var/log/news/errlog. To suppress this redirection, use the ``-r'' flag.
-s After the initial fields, each remaining field names a file to write. The ``-s'' flag may be used to specify a format string that
maps the field to a file name. This is a sprintf(3) format string which should have a single ``%s'' parameter which will be given
the field. The default value is /var/spool/news/out.going/%s. See the description of this flag in filechan(8).
-u If the ``-u'' flag is used, the program will request unbuffered output.
Buffchan can be invoked as an exploder feed (see newsfeeds(5)). As such, if a line starts with an exclamation point it will be treated as
a command. There are three commands, described below:
flush The ``flush'' command closes and re-opens all open files; ``flush xxx'' which flushes only the specified site. These are analogous
to the ctlinnd(8) ``flush'' command, and can be achieved by doing a ``send "flush xxx"'' command. Applications can tell that the
``flush'' has completed by renaming the file before issuing the command; buffchan has completed the command when the original file-
name re-appears.
Buffchan also changes the access permissions of the file from read-only for everyone to read-write for owner and group as it flushes
or closes each output file. It will change the modes back to read-only if it re-opens the same file.
drop The ``drop'' command is similar to the ``flush'' command except that any files are not re-opened. If given an argument, then the
specified site is dropped, otherwise all sites are dropped. (Note that the site will be restarted if the input stream mentions the
site.) When a ctlinnd ``drop site'' command is sent, innd will automatically forward the command to buffchan if the site is a fun-
nel that feeds into this exploder. To drop all sites, use the ctlinnd ``send buffchan-site drop'' command.
readmap
The map file (specified with the ``-m'' flag) is reloaded.
