Cromulent 2018-06-19T22:59:45Z 2018-06-19T22:59:45Z <p>I have a Raspberry Pi 3 Model B+ connected to my local network and I can SSH into it with no problems. This does cause some problems though as everything is done on the command line.</p> <p>What I would really like to do is use X11 forwarding by using the SSH client that comes with Windows Subsystem for Linux. I am running Windows 10 Pro with the 1803 update installed.</p> <p>I'm just curious about how I might go about using this feature? If it won't work in Windows 10 natively then I can always run a Linux virtual machine to connect to the Raspberry Pi.</p> 0 Can Fedora 28 be installed from an ISO file on an LVM partition?

Duncan Bayne 2018-06-19T22:16:32Z 2018-06-19T22:35:24Z <p>I've built a 'ghetto RAID' from a Raspberry Pi, powered USB hub, and two cheap 2TiB USB hard drives:</p> <p><a href="" rel="nofollow noreferrer"><img src="" alt="ghetto RAID"></a></p> <p>It actually works pretty well, but I'm concerned about how Raspbian Lite is handling power management of the USB drives. Specifically, whether the disks are spinning down correctly when not in use, or whether that's solely a device concern.</p> <p>Neither <code>lsusb</code> or <code>usb-devices</code> seems to provide information on drive status. Does anyone know how to obtain it? I'm imagining it may involve querying the device directly in some way.</p> 0 DNS TXT Record V-Server (Let's Encrypt Wildcard) Nimmi 2018-06-19T22:12:06Z 2018-06-19T22:12:06Z <p>i recently switched from a web hosting packet to a v-server (Ubuntu 16.04LTS) and now i am trying to verify my domain to claim a let's encrypt wildcard certificate. To verify that the domain is mine i have to set a dns txt record on a specific subdomain. The problem is that my provider doesn't offer any way to configure dns entrys.</p> <p>Is there another way to get the dns entry done? I thought about running a local dns like bind9 on my v-server but i wasn't able to get it working.</p> <p>I don't know if this is important but my v-server has a SOA DNS Entry on the providers dns (<a href="" rel="nofollow noreferrer">Strato</a>)</p> <p>PS: I know i can use Plesk but i think thats a little bit to big for my taste.</p> 0 Access Database search by checklist user3606616 2018-06-19T22:04:12Z 2018-06-19T22:04:12Z <p>I have a form in Access Database and I would like to be able to select multiple values from a dropdown list and then get all results that match any of the selected values. Unfortunately, I can't find a way to create a multiple checkbox without using a lookup, and from that I can't figure out how to get the value of it. To me it seems like it's always returning null no matter what I have selected.</p> 0 Firefox ESR 52.8.0 Secure Connection Failed IdleImpala 2018-06-19T21:50:06Z 2018-06-19T21:50:06Z <ul> <li>I've recently installed Debian Stretch from netinst with GNOME desktop.</li> <li>Clicking around on Github soon produces a "Secure Connection Failed. The connection to the server was reset while the page was loading." type error on Firefox 52.8.0 ESR.</li> <li>Upgraded Firefox to 60.0.1, seemed better, but after a while still received the same SCF error.</li> <li>Tried with Chromium, similar experience.</li> <li>Checked the Mozilla help pages, no success. </li> <li>Also, websites like khanacademy and wunderlist browser app are not loading at all, these could be related. Wunderlist is sometimes cycling between waiting for the website and performing a TLS handshake.</li> <li>Also, StackOverflow and SuperUser both notified me of too many requests.</li> <li>Another, possibly related browser experience is that a few days ago I wanted to download a file from a shared sharepoint directory, one of the browsers didn't load after I clicked download (FF), the other interestingly required a login which I didn't have (Chromium). Tried on my Windows computer, the download worked flawlessly, and it didn't ask for a login (I was not logged in to the site, this was a third party sharepoint site).</li> </ul> <p>Based on other threads my leads are TLS, SSL, HTTPS, NPAPI, or some active content management, Flash, Java, etc., but I'm no expert in any of these. I am guessing there are some packages I should have installed but I have no clue which.</p> <p>The only plugin I use on FF is AdBlock, my hardware is Intel NUC7i5BNH barebone.</p> <p>Apologies if this question is a duplicate I've yet to find a useful answer. This is the thread I believe is most related: <a href="">Secure Connection Failed</a>. Can someone please point me in the right direction?</p> 0 Distribute wifi to other building Farid 2018-06-19T21:41:10Z 2018-06-19T22:15:14Z <p>I need distribute wifi from home (wifi antenna) to other building (smartphone).</p> <p>Path between buildings 200m, brick walls, line of sight, but smartphone inside the room.</p> <p>It is possible? And which model of wifi antenna i must set up?</p> 0 Do Excel UDFs update when you apply sort Fus Ro Dah 2018-06-19T21:31:34Z 2018-06-19T23:29:15Z <p>As the question suggests, I'm seeing side effects (slowness) of the UDFs I've created when I apply a sort to my spreadsheet. I've created some UDFs in .NET and have deployed for testing. The function, behind the scenes, makes an API call then returns the data back to the cell. So I'm expecting some delay when I create the function to run initially. <em>BUT</em> I'm seeing some slowness in the application when I sort columns as if the UDFs are recalculating and calling the APIs. Is this normal behavior of the spreadsheet?</p> <p>My function does have cell references and looks like the following:</p> <pre><code>=wsStateMiles("ALKCUR",G45,K45,1,J45,$G$2) </code></pre> <p><a href="" rel="nofollow noreferrer"><img src="" alt="enter image description here"></a></p> <p>When I remove the function, the spreadsheet sorts very quickly, as the first thing I tried to deduce was actual slowness of Microsoft Excel. </p> <p>(Additional info)</p> <p>This has nothing to do with the sort, but when I add additional UDFs, it almost seems like Excel is running so slow it's recalculating the entire spreadsheet's UDFs again. Again, is this normal behavior of Excel?</p> 0 Return temperature data in Google Sheets for a specific time of day for each day of the month KamikazeCricket 2018-06-19T21:25:03Z 2018-06-19T22:38:21Z <p>I have a column for date and time formatted like so: [3/4/18 1:09] (verified that this is stored as date/time values), and a column for the temperature data at that time in °C like so: [11.536]</p> <p>There is a reading for every minute and over a month this adds up to over 40K entries.</p> <p>What I want to do is to make a separate column for the temperature readings for a specific time of day for each day of the month.</p> <p>So for example I want it to tell me the temperature for 9:00 AM for every day of March.</p> <p>I'm then going to compare these readings to the daily and monthly temperature averages.</p> <p>I would like to stick to using functions and not use pivot tables since I'm going to be doing some other things with this later.</p> 0 Changing the font of cross-references in a Word 2010 document Sam 2018-06-19T21:14:30Z 2018-06-19T22:10:41Z <p>I have a very large word document (250 pages) with lots of cross-references inserted in the text (mainly tables and figures as Figure 2.1 or Table 4.3 etc).</p> <p>The main text of the document is set to Calibri 12. The font of the cross-references is coming up as Arial 12.</p> <p>I have too many cross-references to change them all manually. I have searched on Google to see if I can find style-set for the 'cross-referencing text' so I can change it to Calibri 12, but I am not having any luck.</p> <p>I need this done fairly soon for a thesis, I hope some can help me with this. I am using Word 2010.</p> 0 windows 10 Home errors with vb6 inet control on networked drive kpg 2018-06-19T17:30:46Z 2018-06-19T23:01:29Z <p>Got a utility program I wrote many years ago in vb6 that uses the vb6 inet control to access a website to update itself. The update feature works fine on hundreds of machines running XP, win7, win8, win10, svr 2003, and others, installed on local and networked drives.</p> <p>There is however one new win 10 home machine where it does not work (the update, the program itself works fine) if the program in run from a networked drive. If run it from the c: drive it works, if copied to the networked f: drive I get the error 'Name not resolved', referring to the update site url.</p> <p>I turned off the MacAfee firewall with no effect. The program is digitally signed so it should be trusted. The url is working, and can be navigated to from IE and Chrome on the machine.</p> <p>The program was originally installed on the c: drive but an identical copy resides on the f: drive, and the program runs fine on the networked drive it just can't connect to the update site.</p> <p>Is this a security feature, if so how do I disable it, or is this a limitation of win 10 home (as opposed to professional).</p> <p>I know home has some limitations, like it does not support remote desktop (which is stupid IMO).</p> <p>How can I trouble shoot this problem?</p> <p>MORE INFO:</p> <p>So I uninstalled the program from c: with the intention of re-installing on networked f: to see it that has some effect. However, in the wise installer I cannot select a networked drive for installaion...only c: and cdrom d: are listed. Why can't it see the mapped drive letters?</p> <p>MORE:</p> <p>After reboot wise installer can see networked drives. Installing on network does not fix the problem. In addition to the vb6 inet control, API calls to wininet fail from exe on network but succeed from exe on local c: drive.</p> <p>SIMPLE PROBLEM RESTATEMENT:</p> <p>some.exe (32-bit) uses wininet.dll to connect to internet to post some data to <a href="" rel="nofollow noreferrer"></a>. some.exe is installed at c:\path\some.exe and also on a network share f:\path\some.exe.</p> <p>from cmd prompt:</p> <p>c:\path> some.exe (works)</p> <p>c:\path> f:\path\some.exe (fails with error 12007 name not resolved)</p> <p>f:\path> some.exe (fails with error 12007 name not resolved)</p> <p>f:\path> c:\path\some.exe (works)</p> <p>conclusion: if some.exe resides on a network share internet access is blocked.</p> <p>McAfee is uninstalled. Firewall is off. Internet security zones set to minimum. target url added as a trusted site.</p> 0 How to not group File Compare (Fc.exe) matches [on hold] Mark Dodsons 2018-06-19T16:12:43Z 2018-06-19T22:00:58Z <p>In my example here:</p> <pre><code>Comparing mount and MOUNT2 ***** mount C:\WinPE_amd64\mount\Users\Public\Pictures C:\WinPE_amd64\mount\Users\Public\Videos ***** MOUNT2 C:\WinPE_amd64\mount\Users\Public\Pictures C:\WinPE_amd64\mount\Users\Public\Public Test C:\WinPE_amd64\mount\Users\Public\Videos ***** ***** mount C:\WinPE_amd64\mount\Windows\ITCMD\Logo.txt C:\WinPE_amd64\mount\Windows\Logs\CBS ***** MOUNT2 C:\WinPE_amd64\mount\Windows\ITCMD\Logo.txt C:\WinPE_amd64\mount\Windows\ITCMD\Second Help.txt C:\WinPE_amd64\mount\Windows\ITCMD\Second Logo - Copy.txt C:\WinPE_amd64\mount\Windows\Logs\CBS ***** ***** mount C:\WinPE_amd64\mount\Windows\Pale\Lib\Mozilla\Plugins C:\WinPE_amd64\mount\Windows\Pale\ReadMe\Acknowledgements.txt C:\WinPE_amd64\mount\Windows\Pale\ReadMe\Palemoon-Portable-license.txt ***** MOUNT2 C:\WinPE_amd64\mount\Windows\Pale\Lib\Mozilla\Plugins C:\WinPE_amd64\mount\Windows\Pale\ReadMe\Palemoon-Portable-license.txt </code></pre> <p>Desired Output:</p> <pre><code>Comparing mount and MOUNT2 ***** mount C:\WinPE_amd64\mount\Users\Public\Pictures C:\WinPE_amd64\mount\Users\Public\Videos ***** MOUNT2 C:\WinPE_amd64\mount\Users\Public\Pictures C:\WinPE_amd64\mount\Users\Public\Public Test C:\WinPE_amd64\mount\Users\Public\Videos ***** ***** mount C:\WinPE_amd64\mount\Windows\ITCMD\Logo.txt C:\WinPE_amd64\mount\Windows\Logs\CBS ***** MOUNT2 C:\WinPE_amd64\mount\Windows\ITCMD\Logo.txt C:\WinPE_amd64\mount\Windows\ITCMD\Second Help.txt C:\WinPE_amd64\mount\Windows\Logs\CBS ***** ***** mount C:\WinPE_amd64\mount\Windows\ITCMD\Logo.txt C:\WinPE_amd64\mount\Windows\Logs\CBS ***** MOUNT2 C:\WinPE_amd64\mount\Windows\ITCMD\Logo.txt C:\WinPE_amd64\mount\Windows\ITCMD\Second Logo - Copy.txt C:\WinPE_amd64\mount\Windows\Logs\CBS ***** ***** mount C:\WinPE_amd64\mount\Windows\Pale\Lib\Mozilla\Plugins C:\WinPE_amd64\mount\Windows\Pale\ReadMe\Acknowledgements.txt C:\WinPE_amd64\mount\Windows\Pale\ReadMe\Palemoon-Portable-license.txt ***** MOUNT2 C:\WinPE_amd64\mount\Windows\Pale\Lib\Mozilla\Plugins C:\WinPE_amd64\mount\Windows\Pale\ReadMe\Palemoon-Portable-license.txt </code></pre> <p>You can see that it groups the added lines "Second Help.txt" and "Second Logo - Copy.txt" together in the same difference.

The stateful packet filtering has allowed me to print remotely on my MakerBot, but I could not connect to my home server via SSH today. The SysAdmin Handbook says that stateful packet filtering is the most powerful feature that Netfilter brings to firewalling, but that it may add unneeded complexity to a network. Hence, I will probably cut my losses with stateful packet filtering unless someone can cut the Gordian knot. </p> <p>IPtables -L -v output:</p> <pre><code>0 0 ACCEPT tcp -- any any anywhere icarus.lan tcp dpt:ssh 0 0 ACCEPT tcp -- any any anywhere icarus.lan tcp dpt:www 0 0 ACCEPT tcp -- any any anywhere icarus.lan tcp dpt:https </code></pre> <p>23M 21G ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED</p> <p>For some reason Open-WRT/LEDE resets my default INPUT policy to accept even after I set it to DROP. However, that rule does not seem match anything so I'm not too concerned. You can see above I have packet forwarding set for SSH but that rule is not matching anything.

I've updated to the newest available build.</p> <p>Chromecast is a wireless-only device, for those unfamiliar. The device has been set up and operates normally using wireless devices associated with the router, but wired ethernet devices cannot communicate with Chromecast. Specifically, the Chrome plugin says "No Cast Devices Found."</p> <p>AP Isolation is disabled.</p> <p>I have sniffed packets between a laptop via both wired and wireless connections and Chromecast, and this is what I've found:</p> <p>There are IGMP, TCP, UDP packets between Chromecast and a wireless interface on the laptop.</p> <p>There are IGMP and TCP, but zero UDP packets exchanged between Chromecast and a wired ethernet interface on the same laptop.</p> <p>Specifically, the wired interface does receive the following IGMP packet from the Chromecast:</p> <pre><code>1062 55.011807 IGMP 60 V2 Membership Report / Join group </code></pre> <p>... which is also observable on the wireless interface. Some packets on the wired ethernet interface are marked as having a bad ipv4 header checksum (0x0000), but I've read this is artifactual due to checksum offloading on the NIC.</p> <p>Here is the (redacted) TCP stream observable on the wired interface:</p> <pre><code>GET /ssdp/device-desc.xml HTTP/1.1 Host: Connection: keep-alive Cache-Control: max-age=0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.49 Safari/537.36 DNT: 1 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8,fr;q=0.6 HTTP/1.1 200 OK Application-URL: Content-Type: application/xml Content-Length: 1078 &lt;?xml version="1.0"?&gt; &lt;root xmlns="urn:schemas-upnp-org:device-1-0"&gt; &lt;specVersion&gt; &lt;major&gt;1&lt;/major&gt; &lt;minor&gt;0&lt;/minor&gt; &lt;/specVersion&gt; &lt;URLBase&gt;;/URLBase&gt; &lt;device&gt; &lt;deviceType&gt;urn:dial-multiscreen-org:device:dial:1&lt;/deviceType&gt; &lt;friendlyName&gt;Bedroom TV&lt;/friendlyName&gt; &lt;manufacturer&gt;Google Inc.&lt;/manufacturer&gt; &lt;modelName&gt;Eureka Dongle&lt;/modelName&gt; &lt;UDN&gt;uuid:XXXXXXXXXXXXXXXXXXXXXXXXXXXXX&lt;/UDN&gt; &lt;iconList&gt; &lt;icon&gt; &lt;mimetype&gt;image/png&lt;/mimetype&gt; &lt;width&gt;98&lt;/width&gt; &lt;height&gt;55&lt;/height&gt; &lt;depth&gt;32&lt;/depth&gt; &lt;url&gt;/setup/icon.png&lt;/url&gt; &lt;/icon&gt; &lt;/iconList&gt; &lt;serviceList&gt; &lt;service&gt; &lt;serviceType&gt;urn:dial-multiscreen-org:service:dial:1&lt;/serviceType&gt; &lt;serviceId&gt;urn:dial-multiscreen-org:serviceId:dial&lt;/serviceId&gt; &lt;controlURL&gt;/ssdp/notfound&lt;/controlURL&gt; &lt;eventSubURL&gt;/ssdp/notfound&lt;/eventSubURL&gt; &lt;SCPDURL&gt;/ssdp/notfound&lt;/SCPDURL&gt; &lt;/service&gt; &lt;/serviceList&gt; &lt;/device&gt; &lt;/root&gt; </code></pre> <p>This is apparently not good enough for function, and the lack of UDP packets going in the ath0 --> eth1 (the WLAN and LAN interfaces on the DD-WRT router) direction is suspicious. Can anyone shed light on what may be happening? Bridge and route settings on the DD-WRT are all basically default.</p> 5 Can I use different HP power adapters in one computer? ziga 2012-10-06T14:05:12Z 2018-06-19T23:15:21Z <p>My old HP adapter burned out and it will take 2 weeks for me to get a new one. In the meantime, I borrowed a HP cable from a friend.</p> <p>Is it possible to use a different HP adapter in the mean time?

Chris Moore 2012-03-14T20:57:13Z 2018-06-19T22:33:45Z <p>I've been <a href="">having trouble with dd-wrt on my Linksys WRT56G2 v1 router</a> and want to go back to the <a href="" rel="nofollow noreferrer">stock Linksys firmware</a> for it. The router has only 2MB of flash memory, and so I'm running the 'micro' version of dd-wrt.</p> <p>My question is what is the best way to do that?</p> <ul> <li><p>I could use the <a href="http://router/Upgrade.asp" rel="nofollow noreferrer">http://router/Upgrade.asp</a> dd-wrt "firmware upgrade" web interface to do it, in which case there's a dropdown menu choice for "After flashing, reset to": "don't reset" or "reset to default settings". Which should I pick?</p></li> <li><p><a href="" rel="nofollow noreferrer">Some people</a> say that I should use a program called <code>tftp.exe</code> instead. I can probably gain access to a Windows machine if this is necessary.</p></li> </ul> <p>Which of these is the way to proceed? I don't want to brick the router if at all possible!</p> <p>Note: I used the 'wrt54g' tag because I wasn't allowed to create a 'wrt54g2' tag due my low rep here.</p> 3 How to add a new section to a numbered list in MS Word? kacalapy 2011-04-20T17:15:45Z 2018-06-19T23:08:26Z <p>In Word how can I add a section into a numbered list?</p> <p>I have a large software requirements document that is organized using a numbered list, so I have a few paragraphs as 1, then maybe some sub-points as 1.1, 1.2, 1.3.</p> <p>I am having trouble where Word is starting a new number and not letting me edit into the current flow of the sequence.</p> <p>How can I add a new paragraph into a section such as this so that I can add a new paragraph in-between existing ones and have the rest re-numbered?</p>
