<h1>🌟</h1>
|
|
|
|
<p>I've an internet connection which, for some obscure reasons, tend to be
|
|
very slow from time to time. After rebooting the box (yes, that's a hard
|
|
solution), all the things seems to go fine again.</p>
|
|
<h2 id="edit-using-grep">EDIT : Using grep</h2>
|
|
<p>After a bit of reflexion, that's also really easy to do using directly
|
|
the command line tools curl, grep and tail (but really harder to
|
|
read).</p>
|
|
<p><code>`` sourceCode bash
|
|
curl -X POST -u joel:joel http://bebox.config/cgi/b/info/restart/\?be\=0\&l0\=1\&l1\=0\&tid\=RESTART -d "0=17&2=</code>curl -u joel:joel http://bebox.config/cgi/b/info/restart/\?be\=0\&l0\=1\&l1\=0\&tid\=RESTART | grep -o "name='2' value='[0-9]+" | grep -o "[0-9]+" | tail -n 1`&1"</p>
