Richard's questions

I'm looking for a solution that will allow me to export a desktop app running on a server to a client machine. The server is ideally Linux, the desktop is Windows (+Mac for icing on the cake). The export should be encrypted and I need to support multiple clients from one server. I only want to export an individual app, not a whole desktop, and ideally am looking for open source solutions.

The obvious, cheapest, simplest choice is to use X tunnelled over ssh (e.g using Xming on the desktop) but X doesn't support audio.

What are the alternatives? Or is there a way to support audio using X or in parallel to X?

Thanks

This is essentially a repost of https://stackoverflow.com/questions/4159369/ubuntu-9-04-pecl-extension-downloads-but-does-not-install. Hoping maybe someone can help me here.

I've done this:

sudo apt-get install php-pear 
sudo apt-get install php5-dev 
sudo apt-get install libcurl3-openssl-dev

which installs fine. However, the next step:

sudo pecl install pecl_http 

Doesn't install the extension, but merely downloads it. There are no error messages. So I have unpacked it and built it myself per http://php.net/manual/en/install.pecl.phpize.php Essentially:

cd pecl_http
phpize
./configure
make
make install

I also make test'd to check all ok - and it failed one test: HttpRequest, which is kind of fundamental to this package. And indeed this doesn't work:

$r = new HttpRequest('http://www.google.com');
$r->send;
echo $r->getResponseCode();

No request is sent, the response code is zero, but no errors either.

How can I get this damn thing installed? Is this a bug? Am I doing something wrong? Any alternatives, workarounds? Help appreciated.

Thanks

Every so often at boot time the disk checker runs. It completes ~70% very rapidly, and then takes about an hour to complete the remaining 30%. I know I can cancel it, but presumably it runs for a reason so I'd rather let it complete.

Is it normal to take so long? Is there anything I can do to speed it up?

I have done the following:

shell> sudo apt-get install mysql-server-core-5.1
shell> sudo apt-get install mysql-client-core-5.1

Both seemed to complete fine with no errors. I have the following present:

/usr/sbin/mysqld

However if I try to run this, I get the following error:

mysqld: Can't change dir to '/var/lib/mysql/' (Errcode: 2)

for the simple reason that in fact this directory does not exist. Now the correct way to start the daemon is apparently:

/etc/init.d/mysql start

however this script does not seem to exist either. So has my install totally messed up, or is there a step I am missing?

Thanks

How do I get the current Unix time in milliseconds (i.e number of milliseconds since Unix epoch January 1 1970)?

I am running Ubuntu 9.04 server edition. I have a monitor plugged into the box for occasional admin tasks. I pulled out a USB disk (without unmounting) and the screen is now full with this message:

Buffer I/O error on device sdc1, logical block 7778778

I can't seem to clear the screen or get a prompt back. Doesn't appear to be registering keyboard strokes. The box is still running fine (I can ssh in from elsewhere and evrything is running as normal).

Any ideas on how to clear screen and get my prompt back?

I,ve just installed a fresh copy of Ubunutu 10.04, downloaded a couple of days ago. The installation seemed to go fine. However I can't log in: the login screen just seems to reset and asks me for my password again.

It's not an authentication / incorrect password issue. If I stick in a wrong password, I get "Authentication failure".

I've googled around, others report the same issue on the Ubuntu forums, but there doesn't seem to be a fix. Does anyone know of a work around or what the problem is?

Have 9.10, I might end up just installing that instead.

THanks
