I’m locked out of one website

Beeblebrox Total Posts: 1108 Joined 2005-03-16	Posted: 16 May 2007 08:09 PM A couple of days ago, I stopped being able to access at least one website on my Mac. It’s my own domain so I haven’t been banned or blocked. Everyone else can access the site, so it’s not down. I can access the site from the PCs in my house, so it’s not an ISP issue. I cannot access it from FTP, Firefox, Safari, or anything else on my Mac, so it’s not a browser issue. I can access every other site I’ve tried, so it’s not an internet issue. I’ve repaired permissions. I’ve rebooted several times. What gives? Any ideas? UPDATE: I just tried it on my brother’s computers on the SAME network. His PC could access it but not his Mac. So it appears isolated to Macs on this network. Weird.

woz1984 Total Posts: 1 Joined 2007-05-28	Posted: 28 May 2007 08:04 AM Question: Do you use any VPN-connection? I always have the problem of being locked out of certain websites when I use a specific VPN tunnel. The reason seems to be that the maximum packet size (mtu) is usually in Mac OS X 1500, which is bad for my specific connection, I have to lower it to 1400 & then everything works fine. Maybe you have a similar problem, maybe even not with VPN, but with your router? If you’d like to give this a shot, lowering works that way: - if you’re connected to your network by cable (ethernet): Go to System Preferences - Network, select your connection, choose tab “ethernet”, set mtu to 1400 - if you use your internal Airport card: Open Terminal.app (Applications/Utilities) and type at the command prompt `sudo ifconfig en1 mtu 1400` & enter. You’ll probably be asked for your administration password to execute this command. If all of this doesn’t help, you easily may reverse the settings (ethernet: put mtu on standard again, for Airport just execute the command again with 1500)

The last entries should match. 3: more /etc/hosts --look for an entry in there that points the server name at another IP. Here are things to look for outside of terminal 1: Do you run brickhouse or another firewall? Temporarily disable it. 2: Are you connected wirelessly or via a hub? Temporarily connect the mac directly to the internet. 3: (assuming the server if apache...) Do you have shell access to the machine your site is on? look for a file called .htaccess in the htdocs (or similar) directory. See if it says something about denying access to your IP. 4: Speaking of IPs, try http://123.123.123.123/, where 123… is the IP address of your webserver. [Updated to add: forum software automatically links web addresses, which is not correct for the traceroute command. do not use http..., just traceroute fullyqualifiedserver.domain]

BigMac Total Posts: 714 Joined 2005-08-15	Posted: 29 May 2007 03:21 PM Beeblebrox, I have the same issue every once in awhile only with sites that I frequent often. i.e. a couple of my sites, sitemeter, and feedburner. Each time, it is only my computer and its across multiple platforms. The only way I have been able to fix it is to restart my computer (logout/login doesnt do the trick) No error message just time outs. I realize this gives you no help except to know you aren’t alone.

Here’s what came up when I entered Michael’s suggestions into Terminal: 1.
