To sign the profile, export or email the config file to yourself, have your certificate files handy, and type the following:

openssl smime \
-sign \
-signer your-cert.pem \
-inkey your-priv-key.pem \
-certfile TheCertChain.pem \
-nodetach \
-outform der \
-in ConfigProfile.mobileconfig \
-out ConfigProfile_signed.mobileconfig

The files you’ll need are:

your-cert.pem – this is the certificate you’ve been issued
your-priv-key.pem – this is your private key
TheCertChain.pem – this is the certificate chain (optional, in some cases)
ConfigProfile.mobileconfig – This is the unsigned copy of your configuration profile

The original instructions are located here.

NSNetServiceBrowser
searchForServicesOfType: @"_services._dns-sd._udp."
inDomain: @""

It will return data in the following form:

NSNetService
name = "_workstation"
type = "_tcp.local."
domain = "."

All this documentation taken from here.

Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2

Then you’ll be happy for the fix. You can either download the source code to the ping command from Apple and edit it yourself, or you can download my pre-compiled copy.

If you choose to edit it yourself, you’ll want to comment out lines 977 and 978 so they look like this:

// if (!(options & F_QUIET))
// printf("Request timeout for icmp_seq %ld\n", ntransmitted - 2);

Then just type ‘gcc ping.c’ and you’ll end up with a file called a.out, which you can use to replace /sbin/ping, or put in your local ~/bin directory if you’ve got one.

lpadmin -p Printer_Name -L "Printer Location" -E -v lpd://x.x.x.x -P /Library/Printers/PPDs/Contents/Resources/en.lproj/Printer_Driver.gz

If you don’t specify the -P option, it will not show up in your Print or Printer Setup dialogs. If you want to include the generic PPD, it is located here:

/System/Library/Frameworks/ApplicationServices.framework/Versions \ /A/Frameworks/PrintCore.framework/Versions/A/Resources/Generic.ppd

That path is all one line, with no spaces.

I have a group of Macs that I use to sync data between, and I used to use iDisk, but Dropbox is so much quicker that I can’t see myself using iDisk anymore. Also, the syncing between Linux and Mac OS X works great – I haven’t got a chance to test the Windows client yet, but I’m sure it works just as good.

If you sign up with this link, you’ll get an extra 256MB, and so will I.

I was using a few other applications in the past to manage my SSH keys – in fact, I didn’t even know this was a feature until the new install on a Mac Pro worked without me installing the ‘keychain’ app from fink, or a number of other solutions that I had tried in the past.

To fix this, I had to edit the ~/.MacOSX/environment.plist file. In that file, there is an entry for SSH_AUTH_SOCK which needs to be removed. I just removed the the section that looked like:

<key>SSH_AUTH_SOCK</key>
<string>/tmp/503/SSHKeychain.sock</string>

The text may differ slightly on your computer.

To resolve, either disable clear text passwords on the server side, or change the following plist:

~/Library/Preferences/com.apple.AppleShareClient.plist

You need to change the afp_cleartext_allow value to “Yes” “true” or “1″ (depending on the current values you see, either “false” or a “0″).

Here’s an excerpt from my file:


...
<key>afp_cleartext_allow</key>
<true />
<key>afp_cleartext_warn</key>
<integer>0</integer>
<key>afp_default_name</key>
<string></string>

You can backup 2GB for free, or pay around $5 per month for unlimited backup, which I am thinking about upgrading to.  Recently they released a Mac client which makes this a better option for me.  They also offer a commercial version of the service which called MozyPro.
