Why does my ssh tunnel drop when I switch on a system wide proxy

The subject says pretty clearly what is puzzling me. After I establish a connection via ssh and initiate a tunnel for email access through a corporate firewall (using Apple Mail as the client and POP3 for the protocol), I find that enabling a system wide proxy (socks5, http, and https) via the same ssh tunnel causes the email to stop working. Upon switching, the http proxy (Safari) works fine -- e.g. the tunnel is healthy. This confuses me. The ssh link which hosts several tunnels is fine. I am forwarding local port 10025 and 10110 on the tunnel to a mail server behind the firewall. The socks5 proxy and http proxy are running on local ports 11080, 18080, and 18080, respectively. Why is Apple mail paying attention to the proxy settings at all? It would seem that since Apple Mail makes no attempt to connect (via the Activity window) that the link is dead, however, turning off the proxy brings the email tunnel back to normal. Wierd. Any advice? This is running on a normal 10.4 (not server), but I don't think there are any significant differences in behavior. I asked on the networking discussion, but got no response.

Two things jump into my mind: poor WiFi signal strength on the desktop PC or a dirty OS installation on the desktop PC. I'm quite sure that this has nothing to do with the cisco VPN client itself.
Assuming that you reach your remote workspace through the cisco VPN client it might also be that the remote part (the VPN concentrator) gets congested and drops your connection but than other employees would complain as well (can be checked with your ICT guys).
The thing is: when you lose Internet connection on your laptop while surfing a web site and connection comes back again within no time you won't notice anything. If the same happens to a system constantly receiving encrypted packets and some are missing the VPN client will drop the connection. Completely different protocols (http/ipsec) that are differently prone to packet drops...

  • Why does my font/text change when I switch from Classic 3D to Ray traced 3D in After Effects?

    My font/text changes when I switch from Classic 3D to Ray traced 3D. Why is it doing this? Also, I cant get the font/txt to look the same after I switch from Classic to Ray traced. How can I get it to look the same?

    I am pretty new to After Effects so I hope it's not my inexperience that's causing the problem. (It probably is)
    I just updated to the most current version of AE.
    I am on a mac pro late 2013 12GB 6 core. Running OSX 10.9.4
    Okay so after looking at it a little closer, I think the color is what mostly changes. The first screenshot is the what the text look like with Classic 3D and the second screenshot is what it looks like after I change it to Ray traced 3D. Also under the "Mode" section..the pull down that says "Normal" disappears. I'm wondering why the font color is changing?

  • Why does Photoshop CC keep crashing when I switch between pictures?

    I just switched to Photoshop CC from CS4 and am having frequent troubles with it crashing.  The problem seems to occur when I have 10-15 different pictures open and am combining them into a collage.  When I switch back and forth between the windows, CC locks up and shuts down.

  • Why does Safari go into limbo when I try to search for some things?

         Why does Safari go into limbo when I try to search for some things? I start to enter something in the search window. I get a drop down with suggestion I choose one and it pops up in my search window but just turns a color and does nothing!
        If I quit Safari and bring it back up, then enter the exact same line it's fine. This is just one of the many problems I've been
    having with Safari since I installed Yosemite.
         Has anyone got any suggestions or is anyone having the same problem. Is there a way to maybe force my MacBook pro to reinstall Safari or possibly all of Yosemite. I seem to be having a lot of problems and judging by the responses I've received (That would be None) I must be the only one having any problem at all withYosemite. Not sure what to do.
         Any help or suggestions would be great

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Why does my screen turn black when I play iTunes while working on iPhoto?

    Why does my screen turn black when I play ITunes while working on iPhoto? I can't click off of the screen but get a message that reads Shut down computer by pressing button in back then turn computer back on by pushing button in back. That's followed by Chinese letters (which I cannot read). I have had other problems when playing iTunes (actually, a radio station on the Internet) while working on  iPhoto. Before, I got a window that would pop up and tell me I had no disk space available, that I would have to quit applications that were open. Not many were open.
    It would be nice if I could solve this problem once and for all.
    Thanks in advance for all the suggestions. I truly appreciate your help.

    That was easy. Thanks. Jan

  • Put movies in itunes on one computer why does it not show up when i access itunes from other computers or ipad2?

    put movies in itunes on one computer why does it not show up when i access itunes from other computers or ipad2?

    i just purchased a file that had videos in it. i put them in the itunes library on my pc where i first downloaded them. i was able to transfer them to my other pc, a laptop, through my home network. i am now trying to get them on my mac pro desktop and my ipad2. my mac pro can see the other computers on my home network but i cannot get it to connect to them. i know the operating systems are different but was hoping i could transfer pictures and files from pc to mac this way. haven't been able to get it to work yet. the videos i am trying to get my mac to see came in a folder with both mac and pc versions. i thought if i got the videos i purchased into itunes that i would then be able to get them to my mac pro and my ipad2. i am new to mac/apple and have always been pc-centric so trying to marry it all has been difficult. i speak pc pretty well but am just learning apple. am i trying to do things that are not possible? i sure could use a knowledgable friendly soul to walk me through my issues of having pc and mac on the same network. i have been able to get all computers and ipad to print on my network. thanks.

  • Why does ID create a CSS when option is not selected in export to ePub?

    I am using InDesign 6 to create ePub books. I want to use my own CSS so in the Export to ePub options I am leaving the setting "Include Style definitions" unchecked. I then list my CSS under additional CSS. When I create the ePub and then examine the files included I see that there are 2 CSSs, mine and one created by InDesign. Why does InDesign create a CSS when the "Inlcude Sytle definitions" is left unchecked?

    Because that is the way that CS6 exported EPUB.
    EPUB is a fast moving target and has moved way beyond what CS6 can export. With each update from InDesign CS6 to InDesign CC to InDesign CC 2014, and even to the latest update to CC in October, there have been major changes to how InDesign exports EPUB. It no longer does it that way, and you have much more control over the process in InDesign CC.
    Because InDesign CS6 is never going to change, it's best to work at modifying what they do export, unless you want to upgrade to InDesign CC.

    And what kept you from posting a screenshot?
    I borrowed the image below for an HDR workshop I ran at the 2010 PSNZ National Convention, to demonstrate a method of removing halos.  You'll remember that halos were a serious problem with early HDR, and while the halos in this image were caused by over sharpening, they are perfect for demonstrating this technique.
    It relies on the fact that halos so often tend to put a lighter tone between the two areas where sharpening is being applied. Whether that is the sky abutting a dark line of hills, or the rock and little tower as in this image.  I've uploaded it at the size it was supplied to me at (about 2700 pixels wide).  So
    Click to open the full image, right click and copy, and paste into Photoshop.
    Select the clone tool, and set its blend mode to Darken.
    Try to sample on a line horizontal to where you want to clone, to give the best tonal match, and start cloning.
    Because the sky is darker than the halo, it overwrites it. But the rock is darker than the sky, so it has no affect.
    It works even better if you clone on a new layer also set to Darken.  No masking, just Photoshop blend mode magic.
    You can also fix the little tower. Use a great big brush — just remember to sample horizontal to match the horizon.
    Back then I was using the same trick with CAs after forgetting to fix them in ACR, and having done too much work to start again after spotting the problem.

  • Why does i photo not launch when i click on icon in dock?

      Help why does i photo not launch when i click on icon in dock?

    The icons in the Dock are aliases. If iPhoto isn't launching from the dock the alias may be broken. What you can do is first test to if iPhoto is working by launching the app from the Applications folder. Once you have determined iPhoto is OK then remove the old Dock icon by holding it down and dragging it to the desktop, it will disappear in a puff of smoke. Then go to the Applications folder and drag the iPhoto icon to the Dock and test it.

  • Why does the iPod duplicate songs when updating my playlists?

    Why does the iPod duplicate songs when updating my playlists? Also, you cannot use the "show duplicate songs" feature on the iPod - I suppose that is because it is not supposed to duplicate songs on the iPod. But, if that is the case - why does it do it?

    Try resetting your iPod, press and hold the power and the home buttons together approximately 15 seconds until the Apple logo appears. If that does not work try going into Settings>General>Reset>Reset All Settings. If that does not work try connecting to you iTunes library via the cable and un-sync the library from your iPod then sync the library.  For the next 2 options backup your iPod first, then do a Restore iPod from backup, if that doesn't work... As a last resort Restore your iPod as New. I too had the red circle and square after updating to 7.0.4 the last resort fixed mine, others have reported doing all the above, all have had reports of fixing the problem and not fixing it. Give it a try, hopefully one of these works, Good luck.
