I have my own root certificate that I have imported into my OSX 'login' keychain and told it to trust across the board. I am now creating a certificate for S/MIME. I create the CSR in Keychain Access and then sign it with the root key and certificate:

sudo openssl x509 -req -days 365 -in $1 \
  -CA ca.crt -CAkey ca.key \
  -set_serial 1 -out $2 -setalias $3 \
  -addtrust emailProtection \
  -addreject clientAuth -addreject serverAuth -trustout \
  -extfile smime.extensions

where smime.extensions contains the following:

basicConstraints=critical,CA:FALSE
keyUsage=critical,digitalSignature,keyEncipherment
extendedKeyUsage=emailProtection
subjectKeyIdentifier=hash
authorityKeyIdentifier=keyid,issuer
subjectAltName=email:copy
nsCertType=email

I get a generally good-looking certificate, but when I import it into the keychain on the OSX machine, it complains that "This certificate was signed by an unknown authority".

Am I missing something to make the proper connection between the CA certificate that I've imported and the S/MIME certificate? Thanks.

This is a real long shot, but I figure it can't hurt to throw this out here:

I have an IP camera that has an RTSP stream with h.264 video and G.711 audio. I setup a Wowza application (myapp) to use the rtp-live StreamType and then got Flowplayer with the RTMP plugin correctly playing the video. However, I believe the audio isn't being transcoded (it sounds horrible and I don't have transcoding on).

My Streams/StreamType in conf/myapp/Application.xml is rtp-live. I have the RTSP stream specified in content/camera.stream. That's really it, and it works, putting out a standard RTMP stream at rtmp://myserver/myapp with stream camera.stream.

So, I've been trying to enable transcoding of the audio while passing through the video, but everything I find (the Transcoding Guide and others) just confuses me more and all my attempts don't work, often with errors about missing SMIL files (I tried to follow a guide but I might have missed something). I found one guide that specifically outlines audio-only transcoding, but of course I had no luck.

Is this the correct way to approach things? I thought it was and then tried to follow the Flowplayer example for dynamic streaming with Wowza using the F4M and HTTP Streaming plugins, but no joy.

I think a lot of my problem is it's unclear to me what URL format I should use to reference my streams

http://myserver:1935/myapp/smil:camera.stream.smil/manifest.f4m

or maybe

http://myserver:1935/myapp/_definst_/ngrp:camera.stream_all/manifest.f4m

?

Any suggestions of where to start? What should my Application.xml and my transcoding template look like? Thanks.

I have a server running 9.04 and I'd like to upgrade it to 9.10 (on the way to getting to the latest version). However, despite following the nice documentation, I am unable to.

Specifically, sudo do-release-upgrade fails:

Checking for a new ubuntu release
Done Upgrade tool signature

Can not upgrade 

An upgrade from 'jaunty' to 'lucid' is not supported with this tool. 

My original /etc/apt/sources.list:

## EOL upgrade sources.list
# Required
deb http://old-releases.ubuntu.com/ubuntu/ jaunty main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jaunty-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jaunty-security main restricted universe multiverse

# Optional
#deb http://old-releases.ubuntu.com/ubuntu/ jaunty-backports main restricted universe multiverse
#deb http://old-releases.ubuntu.com/ubuntu/ jaunty-proposed main restricted universe multiverse

Changing jaunty to karmic and old-releases to releases gives 404 errors when I run sudo aptitude update. And, sudo do-release-upgrade still tries to upgrade directly to lucid.

I have reinstalled Ubuntu 9.10 Server several times on a bog standard 1RU server and each time I finish the install and reboot I see GRUB run and am then presented with a black screen. The machine is running just fine, as I am able to SSH in, but I can't see anything on the attached monitor. I have a simple LCD screen connected via VGA and a signal is apparently being output to it, as it doesn't go asleep.

Looking at /var/log/syslog I see:

Mar 24 14:57:44 bridge5 rsyslogd-2039: Could no open output file '/dev/xconsole' [try http://www.rsyslog.com/e/2039 ]

However, I later see:

Mar 24 14:57:44 bridge5 kernel: [ 0.001368] console [tty0] enabled

Any thoughts? Thanks!

aptitude install mysql-server while throw up a prompt asking for me to set the root password. I'd like to avoid this by specifying the password in the initial command. How do I do this?
