Problems going through a Linux gateway
Greetings,
I am using a Linux box at home to drive my DSL connection, and share it with all other machines (using Netfilter's built-in NAT abilities). It's an Ubuntu Dapper running kernel 2.6.15.
My Windows box has no problem at all and can access any web site. So does my PSP, for that matter.
On the other hand, my brand new Santa Rosa MBP can only access SOME web sites : google and a handful of others. I can also establish a stable ssh connection with a friend's server across that very same internet connection. With most sites, though, the browser starts making requests, then goes into timeout. For instance, I can't load www.apple.com : the browser's status bar (and a network traffic analyzer) show a bunch of requests, then everything freezes after requests are sent to images.apple.com.
I have the exact same symptoms under various settings :
- MacOS X wirelessly connected to the linux gateway (through a Netgear AP) - Safari and Firefox both
- MacOS X physically connected to the linux gateway (through another switch) - Safari and Firefox both
- Windows XP (Boot Camp) wirelessly connected to the linux gateway (through a Netgear AP) - Internet Explorer
Since the problem also appears when wired in, it's not a wifi problem. I've tried fooling around with the MTU (lowering it on the MBP), but no cigar.
One final word : I can access the internet just fine using my neighbour's AP, so I'm almost certain it's a compatibility problem between my MBP and the linux gateway.
Any help would be greatly appreciated!
Well I must give you credit because a lot of people don't know anything about the MTU settings. What setting is it at right now? Is it the same as your PC's?
Try firefox or Flock as an alternative web browser just for now for Diagnostic Perposes.
Otherwise, my notebook and my brothers iMac works fine through a linux gateway.

Email becomes unreadible after going through Cisco email gateway
Hi all,
I have an issue with one sender who is trying to email password protected attachments to other staff in our organization.
The issue seems to only occur when the email goes through our C370, if he sends to an externally hosted email account the email and attachment can be opened, and when that email is then sent as an attachment back into our organization it is also openable, which seems to rule out our clients.
Sanitized header from the C370 below is part of the message header which I think might contain the problem, I have removed the first part with to & from as I didn't know if it was relevant..

Problem on installation of linux through the vmware software on compaq CQ60
Problem on installation of linux through the vmware software on xp operating system. My laptop is Compac CQ60.

when I download the new itunes (on my pc); going through the dowload process it stop me and a window pops up and it says: (there is a problem with this windows installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.)
I have tried several times to redownload and keep getting the same message. what am I doing wrong...Let's try the following user tip with that one:

When I send a text, it goes through as a "text message" instead of an "imessage" and the person I am texting has an iPhone. what could be the cause of this problem?
It's not enough for the other person to just have an iPhone. They must be on iOS 5, have iMessage enabled and connected to the Internet.

In iTunes I'm having problems changing the "Media Kind" in the OPTIONS menu from "Music" to "Audiobook". After going through the steps, the next time I check, the items have reverted back to "Music". What must I do to save it as an "Audiobook"?
After more digging in the Support section here and some Google work, I turned off iTunes Match and lo and behold! I can change the media kind to Audiobook! So, it looks like iTunes Match locked the files up somehow and for some reason.
I went into iTunes Store > iTunes Match > "No, Thanks" to disable it on the local PC. -
For the past few weeks when I place a bid on ebay, Firefox crashes. The bid goes through but I have to restart Firefox each time. I have sent a report each time and asked to be notified and as of yet I have not got a solution to this problem.
I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6. -
I am having problem with my imessages not going through
I am having problems with my tx messages not going through. some do and some don't
Do you mean after a phone update? Do you mean just at home? Does it happen everywhere? Do you have wifi turned on? If its on and your not connecting just clear out the connections (forget) then reset up the connections and see if that helps. Did you get a Jelly Bean update? Many people have had wifi connections issues because your router is either outdated and not supported with the new os, or it needs a firmware update. Post back with more information.

My problem is using the I Photo and printing a picture with horizontal lines going through it
Your topic title and topic content are a bit confusing? Are you printing a website page? That would be thru Safari or other browser.
Or is a photo from a website? If so how was it imported into iPhoto?
Also what system and iPhoto version are your running?
Does the photo print correctly from Preview or other application?
What's the pixel dimensions of the image?

has anybody else having problems with their credit card going through when it is good?
Each time that you add or change your credit card details on your iTunes account a small temporary store holding charge may be applied to check that the card details are correct and valid and that it's registered to exactly the same name and address as on your iTunes account - it should disappear off your account within a few days or so.

I went through an Adobe update and when my computer rebooted, the default font for everything was in italics. For example, when I go to Yahoo.com, the headings for all the news articles and tabs are in italics. I tried going through the Troubleshooting steps to no avail. I am frustrated because I followed the advice of checking the default font under Tools, then I opened the browser in Safe Mode, then I checked to make sure all the fonts were available. So how can I get my fonts back to normal? The italics gives me a headache.
The usual cause of that issue is a corrupted or missing font that Firefox replaces by another, in this case a bold, font.
As a test you can try to disable the default font and choose a few different fonts (Arial, Verdana, Tahoma, Times New Roman) to see if you can identify the culprit.<br />
you will have to reinstall that corrupted font. -
Scrolling through fonts problem (goes to the end of the list)
hi!
i have a text selection and i am going through the installed fonts by hitting the up/down arrow in the "Character:" drop-down list. What happens is when i come across a font that for some reason doesn't have a the name displayed in the textbox, the current selection goes at the bottom fo the font list.
any idea why this happens and if it can be fixed somehow?
thanks for readingI can't fully explain the reasoning behind why it works the way it does, but I am nearly certain you can fix this by opening up your Type preferences (The Type section of prefs) and unchecking "Enable Missing Glyph Protection".
