Installed #! Linux with encryption; computer no longer boots
I am not sure your POSTING (I suspect thats happening behind the
splash screen before the network boot attempt). Have you tried
holding down the escape key as you boot the system then press F1
when you get the check system message ?
It seems to me (but of-course, I don't have one of these PC's)
that while reinstalling GRUB you managed to kill the contents of
the boot sector of the disk - thus the computer is unable to find
a boot image on the disk so it moves on to the next device to try
and boot from it - ie the network card.
If you can boot into the BIOS maybe you can set it to boot off a
USB key, and then either use that to repair your installation or
do a new install ?
description
This program
can be used to send requests to WWW servers
and your local file system. The request content for
POST and PUT methods is read
from stdin. The content of the response is printed on
stdout. Error messages are printed on stderr. The program
returns a status value indicating the number of URLs that
failed.
The options
are:
-m <method>
Set which method to use for the
request. If this option is not used, then the method is
derived from the name of the program.
-f
Force request through, even if the program believes that
the method is illegal. The server might reject the request
eventually.
-b <uri>
This URI will be
used as the base URI for resolving all
relative URIs given as argument.
-t <timeout>
Set the timeout value for the
requests. The timeout is the amount of time that the program
will wait for a response from the remote server before it
fails. The default unit for the timeout value is seconds.
You might append "m" or "h" to the
timeout value to make it minutes or hours, respectively. The
default timeout is ’3m’, i.e. 3 minutes.
-i <time>
Set the If-Modified-Since
header in the request. If time is the name of a file,
use the modification timestamp for this file. If time
is not a file, it is parsed as a literal date. Take a look
at HTTP::Date for recognized formats.
-c
<content-type>
Set the Content-Type for the
request. This option is only allowed for requests that take
a content, i.e. POST and PUT .
You can force methods to take content by using the
"-f" option together with
"-c". The default Content-Type for
POST is
"application/x-www-form-urlencoded".
The default Content-type for the others is
"text/plain".
-p
<proxy-url>
Set the proxy to be used for
the requests. The program also loads proxy settings from the
environment. You can disable this with the
"-P" option.
-P
Don’t load proxy settings from environment.
-H <header>
Send this HTTP
header with each request. You can specify several, e.g.:
lwp-request \
-H 'Referer: http://other.url/' \
-H 'Host: somehost' \
http://this.url/
-C
<username>:<password>
Provide credentials for
documents that are protected by Basic Authentication. If the
document is protected and you did not specify the username
and password with this option, then you will be prompted to
provide these values.
The following
options controls what is displayed by the program:
-u
Print request method and absolute URL as
requests are made.
-U
Print request headers in addition to request method and
absolute URL .
-s
Print response status code. This option is always on for
HEAD requests.
-S
Print response status chain. This shows redirect and
authorization requests that are handled by the library.
-e
Print response headers. This option is always on for
HEAD requests.
-E
Print response status chain with full response
headers.
-d
Do not print the content of the response.
-o <format>
Process HTML
content in various ways before printing it. If the content
type of the response is not HTML , then this
option has no effect. The legal format values are;
text, ps, links, html and
dump.
If you specify
the text format then the HTML will be
formatted as plain latin1 text. If you specify the ps
format then it will be formatted as Postscript.
The
links format will output all links found in the
HTML document. Relative links will be
expanded to absolute ones.
The html
format will reformat the HTML code and the
dump format will just dump the HTML
syntax tree.
Note that the
"HTML-Tree" distribution needs to
be installed for this option to work. In addition the
"HTML-Format" distribution needs to
be installed for -o text or -o ps
to work.
-v
Print the version number of the program and quit.
-h
Print usage message and quit.
-a
Set text(ascii) mode for content input and output. If
this option is not used, content input and output is done in
binary mode.
Because this
program is implemented using the LWP library,
it will only support the protocols that LWP
supports.
