OS X v10.5.1 and later include an application firewall you can use to control connections on a per-application basis (rather than a per-port basis). หากคุณใช้ไฟร์วอลล์ Mac เช่น Little Snitch คุณอาจสังเกตเห็นว่ามีการใช้งานแกนนำในการเข้าถึงอุปกรณ์ในเครือข่ายท้องถิ่นเป็นครั้งคราว. Because it looks interesting enough to have a closer look to me, digging since years mostly in linux, bsd and unix worlds. Could be something that one can advise to relatives and friends for that linux does just not fit.

Click here to return to the 'Easily disable network connections when necessary' hint

On my iBook, since there are times when I'm using it wth no network access, I have created a location called Networkless. This location simply has all of the network interfaces disabled, ethernet, modem, and Airport. With them all disabled, there is no IP address, and no place for connections to go.

Turning off all the networking interfaces also increases battery life noticably. I have a 'Powered Off' location that has no interfaces that I use whenever I'm not at a place where I can get Internet access, including, and especially, on an airplane.

I've done something similar, only I named mine 'Working Without A 'Net'

Really? Hmm. I just created a new Location, gave it a manual IP address of all zeros, and told it to use the dialup modem [which isn't even connected, since I work in a bldg w/Ethernet].
I applied the new location--twice, once from the Prefs panel and, after closing that, from the Apple menu--but I am still able to surf this web page, post this message, and use iChat. There must be something more to it than that. Are you sure you're actually disconnected from the network?

My guess is that you switched over to dialup without turning off ethernet. OS X supports multiple network interfaces at one time. By switching to dialup, you probably left ethernet as active as well. So you'd still have a valid ethernet connection and a dialup connection with nowhere to go.
To turn ethernet off, go to your Network pane in System Preferences and in the drop down menu where it shows 'builtin ethernet' or 'internal modem' it should also say 'Network Port Configurations'. Through that, just click the ethernet checkbox off. Save that as your no connection location.

This message was supposed to be in reply to osxpounder's comment.

Thanks. I was realizing that while you were posting, I think. You're right. I posted two images on the web to show what needed to happen: I need to make sure my new location is set up using the Ethernet connection [not the modem], and I also need to tell the Mac not to get its IP address the usual way [DHCP in my case]. Screenshots:

ifconfig doesn't jive with configd, Mac OS X's network configuration database. use:
sudo ipconfig set en0 NONE
sudo ipconfig set en0 DHCP

...supposing you're taling about en0. ifconfig might work, but it might also have unforseen circumstances.

This is not a good hint.
It's never a good idea to deliberately enter invalid information into a system preference pane. That's just asking for trouble. Instead, you should simply disable your network interfaces. Here's a step-by-step procedure.
1. Open System Preferences and bring up the Network pane.
2. If you want, create a new location for easy toggling.
3. On the 'Show' popup, select Network Port Configurations.
4. Uncheck everything.
5. Click 'Apply Now.'
At this point, you will have no networking. To re-enable networking, return to the Network Port Configurations interface and check the network connections you wish to enable. Or use the Location menu.

But why not just turn off image viewing in your mail client? Or better yet, find a mail client that gives you the option of always displaying plain text? Very seldom do I get legitimate mail in html, and when I do it's easy enough with PowerMail to click the button loading it into Safari. Meanwhile it never loads images in mail unless I ask it too, and Mail.app has the same function minus the plaintext display. Seems like an awful lot of trouble to work around a poorly designed or configured mail client.

I agree, I always have html disabled in mail.app. What I don't like is that I haven't found an easy way of re-enabling it for a specific message for that once in a lifetime legitimate html email.
I wish it had a contextual menu, instead of me having to dig through the prefs, enable it for all, read message, then disable again. I guess I'll have to come up (see if it's possible) with an applescript like another commenter suggested.

I never said that I was using Mail.app (although I am ;)). It's more of a generic hint. And yes, probably disabling all connections would be cleaner but this works too.

An earlier hint shows an applescript to temporarily turn on HTML for reading an email message. See this hint .

Ummm....

The script will turn on images temporarily so Mail downloads them when needed.

Wouldn't it be more effective to use an app like Little Snitch for controlling all software's unnecessary or unexpected connections to the 'net? Just IMHO.

Especially for using the Help Viewer.
You can get decent performance from Help Viewer by restricting its access to the Internet because part of its problems are from searching networks for files.
Of course, it's only good if you have the help files locally. For instance, a lot of the iPhoto pages came up rapidly once I was free from the network. I'm guessing (I may very well be wrong) that when you are connected to the Internet that it checks for updated help pages before it loads the local, and possibly outdated, file.
