• TB3.0.10: Messages being sent back to me

  - by punkinette64

  Hello, I don't know if this will make any sense to you; but here goes. When I send an email and I get a response, more often than not, in the 'to:' is my email address. However, my email address also ends up in the 'from' column.The 'reply-from' address is nowhere to be found;so I don't have any address with which I can send my reply, as both of them have just my email address. What am I doing wrong here? Is there some set-up in my TOOLOPTIONS set-up incorrectly? The set-up in OPTIONS is pretty difficult to understand and it doesn't offer any 'to' or 'reply-from' choices. This is critical because I just cannot answer my emails because there is no one I can send a reply to. Please, please try to help me. If you have the answer, please email me at: [email protected] Thank you. Blessings. Shiloh

• reverse proxying with NGINX to two back-end servers

  - by aag

  I am trying to learn how to configure the Nginx proxy. All requests from external (www.external.com) should go to internal server 10.10.10.16:2080, except for www.external.com/nagios requests, which should go to internal 10.10.10.18. My location block looks as follows: location ~* / { proxy_buffers 16 4k; proxy_buffer_size 2k; proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Accept-Encoding ""; proxy_pass http://10.10.10.16:2080; } # # nagios server location ~* /nagios/ { proxy_buffers 16 4k; proxy_buffer_size 2k; proxy_buffering off; # proxy_set_header Host $host; # proxy_set_header X-Real-IP $remote_addr; # proxy_set_header Accept-Encoding ""; proxy_pass http://10.10.10.18; } The first location seems to work fine. However, any request to www.external.com/nagios sends the browser into the eternal pastures. Of course, 10.10.10.18/nagios was tested and works fine. What am I missing?

• Is Exchange protected from/allow back dated emails?

  - by David

  Does Exchange Server adequately protect against backdating items in a mailbox folder? I want to determine from an auditing perspective what level of risk exists/what trust can be put into Exchange database records. Is there a (mis)feature that allows end point users to modify the sent/recieved date fields on their own messages? Is there a reasonable way short of hand editing the files for an Exchange Server admin to make such a change? And most importantly: Is there any kind of "sequence number" that we could use to audit Exchange records for evidence of date manipulation (ex. msg100 = Dec 15, msg101 = Dec 10, msg102 = Dec 16)

• mod_rewrite filename from mod_pagespeed back to normal files

  - by British Sea Turtle

  I am hoping someone can help me with this problem. I am moving to a new server and not using mod_pagespeed any more. However we have lots of external links to images on our site using the strange mod_pagespeed filenames. This is not an issue but we do not want to have lots of 404 errors. So I have lots of links like the following : http://www.domain.com/images/150x150xlink.png.pagespeed.ic.pPXw45HSQm.png http://www.domain.com/images/paris_01.gif.pagespeed.ce.vfrkuKUaj0.gif http://www.doamin.com/images/1st2.gif.pagespeed.ce.OUg38q6VbZ.gif How can I redirect them to : http://www.domain.com/images/150x150xlink.png http://www.domain.com/images/paris_01.gif http://www.doamin.com/images/1st2.gif There are thousands of files like this so I am hoping for a simple solution with mod_rewrite, I tried this but it does not work. So any help would be appreciated. RewriteCond %{REQUEST_URI} \.gif\.pagespeed\. [NC] RewriteRule ^(.*?\.gif)\..*\.gif$ $1 [NC,L]

• Monitors go to sleep and come back blue

  - by TahoeWolverine

  Recently, my displays have been turning blue when they wake up from sleep. This has hapeened on my Macbook and on my 2nd monitor on my PC (which I use for VM and remote desktop). It's possible that part of it might be my eyes, but seeing the blue monitor next to my other monitor on my PC has convinced me that something is probably out of place. What might that be?

• Hyper-v back-up

  - by Ddave23

  We are trying to decide a good backup strategy for our new Hyper-V setup. We have 3 VMs on Windows 2008 R2 Hyper-V host. We installed Symantec BackupExec 2010 on the host and have the Hyper-V Agent installed. We would like to perform a full backup at night to tape, and an incremental twice a day to a daily tape. Our environment needs constant protection for our database (Microsoft Access). Any thoughts? Should I be looking at different software?

• How to downgrade a certain package (php) back to karmic

  - by Eugene

  Hi! I've updated from 9.10 to 10.04 but unfortunately the PHP provided with 10.04 is not yet supported by zend optimizer. As far as I understand I need to somehow replace the PHP 5.3 package provided under 10.04 with an older PHP 5.2 package provided under 9.10. However I am not sure whether this is the right way to downgrade PHP and if yes, I don't know how to replace the 10.04 package with 9.10 package. Could you please help me with that?

• how to fight back attacks on my web service

  - by user12145

  My apache webservice is getting a large quantity of requests over the days, each one with somewhat random login to gain access. I identified about 60 such ips(a few sample below), all belong to google. is there a way to find more information about the origin of the attacker? or should I just block these ips. secondly, should I attempt to block the identified ips subnets(74.125.46.*) as a preventive measure? 72.14.194.65 64.233.172.20 74.125.75.19 72.14.194.33 74.125.46.87 74.125.44.91 74.125.46.91

• Back up Linux environment

  - by joesavage

  I'm currently in the process of installing a bunch of stuff I need and getting setup my Linode that I recently purchased. Being a Linux newbie, I'm doing pretty well - but one small mistake can screw everything up for me. I've currently got apache2 and some other things successfully installed and setup how I want them, and DO NOT want this to be ruined by some newbie mistake. What is the easiest way to backup the actual environment itself so that I can restore the backed up environment (with apache2 and things fully working) if I mess up?

• Convert Ubuntu back to windows 8

  - by alex0112

  I recently wiped a windows 8 machine and installed Ubuntu. I now need to sell this machine, and the people I want to sell it to would like it to be running windows 8 again. I've been looking around online, and I was under the impression that I could simply order a recovery disk or a re-install disk or something similar. But I'm getting a lot of different answers. What is the right (legal, cheap, in that order) way to do this?

• Oracle 10g Failover Database - How to fail back?

  - by rrkwells

  I want to know how the failover database concept works after recovery. We have defined our application to connect to a backup database in case the production database fails. If this happens, then all the transactions will be happening on that backup database. Once the production db server is running again, then how do we make sure the changes made in the backup database will be reflected on the production database? We want to make sure that any changes made while failed over are not lost. We are using Oracle 10g.

• USB ports not working after restoring back

  - by jmainock

  After restoring this computer with a backup it appears that 2 of the 5 usb ports no longer work. I'm thinking that there is something corrupted on the backup disk causing the failure. When I plug in a usb keyboard to these ports the system will not recognize the new hardware on the 2 bad ports but does recognize new hardware on the remaining three ports. All the ports were working prior to the restoration.

• UINavigationController back button half works in iPad landscape orientation

  - by drawnonward

  In an iPad application with a UINavigationController, everything works in portrait mode but in landscape mode the back button sometimes only goes back half a level. That is to say, on the first press the title bar animates as if it was popping a controller, and on the second press it animates the content popping. Has anyone found a solution to this? The contradictory solution in this question did not help. I have a shouldAutorotate method in the navigation controller but no others. -(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)inOrientation { return YES; }

• Popover with embedded navigation controller doesn't respect size on back nav

  - by quixoto

  I have a UIPopoverController hosting a UINavigationController, which contains a small hierarchy of view controllers. I followed the docs and for each view controller, I set the view's popover-context size like so: [self setContentSizeForViewInPopover:CGSizeMake(320, 500)]; (size different for each controller) This works as expected as I navigate forward in the hierarchy-- the popover automatically animates size changes to correspond to the pushed controller. However, when I navigate "Back" through the view stack via the navigation bar's Back button, the popover doesn't change size-- it remains as large as the deepest view reached. This seems broken to me; I'd expect the popover to respect the sizes that are set up as it pops through the view stack. Am I missing something? Thanks.

• Ajax and Brower Navigation for Back/Forward

  - by David Rodecker

  I am using a ASP.net form with custom onclick mouse events to modify data values. Upon clicking and updating the values, one div section of the form performs a postback. onclick="__doPostBack('ctl01$phCon1$gridReports','sel1')" This is working well, however when the browser BACK option is selected, the browser opens goes through the history of the DIV ajax/onclick actions prior to going back to the prior URL. I suspect that this may be due to the doPostBack being treated as a browsing operation. Is there a means to perform the necessary ASP.net code events to make the page work, but not have the action stored in the browser history?

• Android Maps Back Button

  - by aaronr

  I'm developing an application that shows a path on a map, determined by a KML file. Specifically, in the MapActivity that is starting the map: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); MapView mapView = (MapView) findViewById(R.id.mapview); mapView.setBuiltInZoomControls(true); Uri uri = Uri.parse("geo:0,0?q=http://urltokml"); Intent mapIntent = new Intent(Intent.ACTION_VIEW, uri); mapIntent.setData(uri); startActivity(Intent.createChooser(mapIntent, kmlFile)); finish(); } The map loads fine and after a few seconds the path described by the KML shows up. The problem is, when I press the "Back" button, it does not return to the previous screen but instead just hides the KML overlay. If the "Back" button is pressed again, it will return to the previous screen. Any ideas of how to solve this?

• Obj-C : Passing parameters back from a detailViewController in a navigation controller

  - by Garfield81

  Hi I am using a navigation Controller on an iPhone app. I am able to pass data forward when I push a controller into the navigation stack but how do I pass data back when I pop the controller. What I am basically trying to achieve is the root navigation controller view displays a number of fields that can be edited. A user then clicks on one of the fields to be edited and a EditViewController is pushed onto the stack with the name of the field the user wants to edit. Now the users enters the new value of the field and presses save to pop the view controller. So how do I get the value from the editViewController back to the root navigation controller view?

• Single Page Navigation w/ Javascript and Back Button

  - by Khan

  Ok, so I have a "navigation" div and "content" div. When something on the navigation is clicked, I fade in the content div with the new data. Now, I would like to have the old data returned when the user hits the "back" button on his/her browser, but I'm having a hard time doing this. I know I can set the content to be a named anchor, so they stay on the same page with a breadcrumb trail. However, that's as far as I get. Can I listen for a back button click? Can I set content to display when a certain anchor name is reached? Thanks in advance for your help, SO.

• Android back button does not restart activity?

  - by Chris

  My app intiates an activity. On the click of a button, the app opens up the browser with a webpage. When I hit the back button, it comes back to my initial activity screen, but does not resume or restart the activity. When I put all the layout code and activity code in onResume instead of onCreate, the activity gets restarted. My question is whether this is the right way to go about it? Can I use onResume to draw my layout and initiate the activity, or is this poor design? When the browser fires up, does the initial activity forget its layout? Please let me know what you suggest. Thanks Chris
