My invocation currently looks like this:</p><p><code>tcpdump -IUnSA -y IEEE802_11_RADIO -i $iface</code></p><p>Using -A or -x I can detect the beginning of the next packet, since the header details are distinct from the packet dump, but I can't detect the end of the current packet. Is there a way to detect the end of the current packet in this context?</p><p>(An acceptable alternative for my application is to print the packet length in the header summary and avoid printing the packet dump.

What I would like to do is the following:<br>1) Have a workbook with, say, 100 worksheets<br>2) Each worksheet has a different tab name<br>3) Each worksheet contains a range of cells, where I will type entries which may or may not be the tab name of another worksheet<br>4) If I happen to enter the tab name of one of these worksheets in any cell, on any worksheet, this name gets automatically hyperlinked to that worksheet, so that by clicking this cell I’ll get redirected to that worksheet. In this destination worksheet I can do the same with the cells and get redirected to another worksheet, and so on, hopping from one worksheet to another. </p><p>Any idea on how to set up a range of cells this way? </p><p>I know Excel automatically creates Internet hyperlinks when a cell entry begins with "http://" or "www." Can it also be done when the destination is in the same document rather than on the web?</p><p>The closest solution I was able to find is this formula, entered i.e. in cell C3:</p><p>=IF(A3="P",HYPERLINK("[Test.xlsx]Production!D2","NEXT >>>"),HYPERLINK("[Test.xlsx]Supply!D2","NEXT >>>"))</p><p>If the value in cell A3=P, and I click the hyperlink in cell C3, it will take me to cell D2 of Production worksheet. For any other value in A3, it will take me to cell D2 of Supply worksheet.</p><p>But this is still not what I’m looking for. I would like in my case being able to enter “Production” in A3, be converted in a clickable link as it’s the name of a worksheet, and being redirected to Production worksheet when I click on A3, not on other cells.</p><p>I looked into IF formulas, but they cannot perform any action other than calculate, copy values, etc. So I suppose my only option is using VBA, which unfortunately is not my forte.</p><p>Any help will be really appreciated.</p>http://superuser.com.xemphimonlines.com/q/12857360Get a specific product code © superuser.comRalthttp://superuser.com.xemphimonlines.com/users/8625282018-01-15T14:28:26Z2018-01-21T07:30:03Z<p>I have <code>Matlab Runtime Compiler 2015b (32-bit)</code> installed from their <a href="https://uk.mathworks.com/products/compiler/matlab-runtime.html" rel="nofollow noreferrer">website</a>.

It has the Linux boot manager in the list, but the boot order didn't specify anything about it. So, I manually edited the boot order by <code># efibootmgr -o 1003,1001,2001</code>. But, the problem is the same. The boot order is reverted back after an reboot.</p>http://superuser.com.xemphimonlines.com/q/9894450BASH string manipulation, syntax errors © superuser.comCybexhttp://superuser.com.xemphimonlines.com/users/3898762015-10-20T21:36:48Z2018-01-21T07:49:01Z<pre><code>http://superuser.com/script: line 1: #!/bin/bash: No such file or directory enter ip&gt;&gt;&gt; : 10.00010.00 0 http://superuser.com/script: line 8: [0!=.]: command not found http://superuser.com/script: line 13:=: command not found</code></pre><p>script</p><pre><code>#!/bin/bashvar="0/24"echo "enter ip"read -p "&gt;&gt;&gt; : " ipaddrecho ${temp} echo ${ipaddr%?} #display whole string except last characterecho ${ipaddr:(-1)} #display last character in stringwhile [${ipaddr:(-1)}!="."] #loop till ${ipaddr} last=="."do${cur}=${ipaddr::-1}echo $curdone #remove last char if !="." $temp=${ipaddr}${var} #add string ${var} to end of ${ipaddr}echo ${temp}</code></pre>http://superuser.com.xemphimonlines.com/q/9736321How to fix “Your connection is not private” on Google Chrome 45 (Linux version)? © superuser.comKevin Guanhttp://superuser.com.xemphimonlines.com/users/4978652015-09-16T02:49:20Z2018-01-21T07:30:17Z<p>I want to visit <code>https://gist.github.com/</code>.

First, it wasn't working at all. Then during restart, for a little while, it seemed like the buttons attached to the joystick and external mouse were both swapped left/right. Then I went into the Dell touchpad control and disabled the touchpad and re-enabled it and nothing happened. Then a short while after disabling the joystick the touchpad started working.</p><p>So I restarted to see if it would keep the settings and before login, the touchpad appeared to work, then after login, it stopped working for a few minutes while login continued. Then after the login was almost completed it started to work again. It appeared to have retained the settings for the disabled joystick.</p><p>It seems like perhaps there are conflicting mouse drivers trying to simultaneously or similar.</p><p>This doesn't seem normal for the touchpad to be disabled for so long after login.
