| Sending HTML to konqueror from the
command line (via a named pipe) |

2006-11-24 00:48:42 |
With the help of some posters over on the lvlug list
(lvlug thelinuxlink.net), I've been able to send HTML to
firefox and
lynx from the command line (via a named pipe).
I can't get the same thing to work with konqueror.
Here's what works in lynx and firefox:
[rhks14 rhk]$ mkfifo foo.html
[rhks14 rhk]$ echo
"<HTML><HEAD></HEAD><BODY>TEST&
lt;/BODY></HTML>" > foo.html
Then, in firefox, browse to file:///rhk/foo.html, or start
firefox (or lynx)
with:
mozilla-firefox file:///rhk/foo.html &
Tried the same thing, and quite a few variations, with
konqueror and none of
them work.
(The following is just a partial list of some of the
variations--I've mixed
and matched, varied the number of slashes, added my host
name, my fully
qualified host name, tried localhost...
* kfmclient openProfile webbrowsing /rhk/foo.html
* konqueror http:///rhk/foo.html
* dcop konqueror-21622 konqueror-mainwindow#1 newTab
file:///rhk/foo.html
)
Any hints?

No solution. This requires a change in the MIME type handler
(because it
detects as inode/fifo instead of text/html). It also
requires a change in
kio_file, because that one opens only regular files.

It seems to be possible to work around the first problem by
explicitly
specifying a MIME type
kfmclient exec foo.html text/html
Maybe using netcat and one of KIO's "remote"
protocols could be used instead

Did this work for you? It didn't work for me. I got the
same sort of
"infinite loop" I got earlier--the "Open
with" dialog comes up and asks me
what application I want to open the file (pipe) with, I
choose konqueror, and
the dialog comes up again, ad infinitum.

I'll look for a netcat rpm for Mandriva2006, but any further
hints would be
very welcome.
Thanks again!

It worked in the sense that it directly opened konqueror,
which then failed to
load (the kio_file problem Thiago mentioned)

Could be in some bigger networking tools package. The
executable is often
called "nc"

nc + konqi definitely works for streaming html. It's not
elegant, but
it works. I basically used the following commands to do it:
$ mkfifo foo.html
$ nc -lp 8081 -c "/bin/cat foo.html" # Of course,
the port doesn't
need to be 8081--that was just the first number I came up
with.
$ konqueror http://localhost:8081 &
# This command was done in a
different terminal, of course.
$ echo
"<HTML><HEAD></HEAD><BODY>TEST&
lt;/BODY></HTML>" > foo.html
And that's pretty much it. I even put the entire thing into
a loop
just for fun:
$ i=1; while true; do nc -lp 8081 -c "/bin/cat foo.html
&"; echo
"<HTML><HEAD></HEAD><BODY>TEST&
lt;/BODY></HTML>" > foo.html; echo $i;
i=`expr $i + 1`; done

Oops, just got nc and installed it, and no dice.
My version is 1.10 and it has no -c option. So I guessed
that maybe the -e
option is the same or similar, but no dice.
What version of netcat are you using?
My symptoms include that:
* On my first try (which I don't remember so well), the
nc command hung
until I started konqueror, then konqueror displayed some
sort of error
message--I can't recall what it was (maybe something like an
address not
found, but my memory is really bad at times).
* On subsequent tries, when I issue nc -lp 8081 -e
"/bin/cat /rhk/foo.html"
before starting konqueror (on a 2nd try), I get an error
message: Can't grab
0.0.0.0:8081 with bind. (/bin/cat is the right path to cat,
/rhk/foo.html is
the right name for the fifo). In fact, I get this message
whether konqueror
is started or not. When konqueror is started, it hangs with
"localhost
contacted, waiting for reply", and eventually: "An
error occurred while
loading http://localhost:8081:;
Timeout on server; localhost"
I'm looking for documentation on the -c option. Ok, found
some hints:
"netcat v0.7.0 o Added command line switch `-c'
(close), which shuts down the
connection on EOF from stdin without waiting for any answer
..."
Which makes it sound like -q with some (small) number of
seconds might be an
alternate, but no luck there either:
[rhks14 ~]$ nc -lp 8081 -q 15 "/bin/cat
/rhk/foo.html &"
/bin/cat /rhk/foo.html &: forward host lookup failed:
Unknown server error
So I'll keep looking, and try to download netcat version
0.7.0, but I could
probably use some more hints.

I have v1.10, so yours should work the same way. A less
elegant
manner of doing this is just to pipe it in with cat.
$ cat foo.html|nc -lp 8081 -q 10
$ echo
"<HTML><HEAD></HEAD><BODY>TEST&
lt;/BODY></HTML>" > foo.html #This
is in a different terminal, of course.
$ konqueror http://localhost:8081
Unfortunately, netcat won't know when to close the
connection, and so
the browser--in this case Konqueror--will just keep on
waiting for
more input, even though there is none.
Rene
PS The "-e" option requires its own script file.
So try putting the
commands you want into something like htmlstream.sh, and
then do the
following:
$ nc -lp 8081 -e htmlstream.sh

Ok, now it works--for whatever reason something didn't like
that port
number--I switched to port 18000 and now it works.
Thanks!
