Re: autocad 2004 for linux
Yahav shalom, I've spoken with my dad who sells Autocads, and there appears no Linux version for any of the Autocads. If you need just to view stuff generated in Autocad - there are solution (contact me off list for that). As a side note, you may wish to try running autocad on crossover (the commercial version for wine).

However, it now seems that the problem is network/firewall related - not related to my computer at all. Seems that all the MS boxes around me are using a proxy server (even though I asked my local MS sysadmin and he assured me that they are not using a proxy - I later showed him that they are, in fact), and that is why they are able to FTP. I am now able to FTP too - as long as I also use the proxy server. Seems it was just a coincidence that I encountered the problem right after re-installing FC.

Re: between jabber and talkd
There is a secure chat plugin for Pidgin (used to be Gaim) called Off the record - http://www.cypherpunks.ca/otr/ It promises wanders and while I haven't really checked how secure it is, one of my friends whose opinion I trust in such matters likes to use it. This plugin allows you to have secure chats with any other client with OTR capabilities over any protocol (several other clients can be used with OTR, check the web site).

MySQL Cluster for HA? What about PostgresQL PGCluster?
Hello, We are looking at enhancing one of our servers, which runs CentOS 5 on amd64, for HA using Linux Virtual Servers (LVS). The server runs a web site using MySQL 5.0.22 and of course we'll need to replicate that on the second server as well. Is MySQL Cluster the right solution for us? At least for now, we think we can do with a master-slave solution (i.e. only one server serving while the other is in hot standby), but if it's possible to take advantage of both servers at the same time and double our capacity then it would be very useful too. I also have a small web service using PostgresQL (8.1.9, from CentOS packages) on the same server which will also have to be replicated. What do people usually use to do this? Is PGCluster a practical option? Thanks, --Amos = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
Re: MySQL Cluster for HA? What about PostgresQL PGCluster?
Hi, AFAIK MySQL cluster requires using the NDB engine which is not 100% compatible with MYISAM, etc. The more recent a version you have the better off you will be but there was one point where autoincrement wasn't even supported. Also from what I know, a NDB cluster needs at least three nodes. That doesn't mean you can't have an active-active database. If you application is ready for it, you can set up MySQL in a Master Master configuration (aka multimaster). For your application to be compatible you basically need to use only autoincrement primary keys for all your tables but you should read the whole Megilah - here is a good article: http://www.onlamp.com/pub/a/onlamp/2006/04/20/advanced-mysql-replication.html Google has also released some code for multimaster configurations and they have some docs also: http://code.google.com/p/mysql-master-master/ Regarding Postgres- I can't recommend anything specific but I am looking into pgpool and pgpool II for a new project.

Also from what I know, a NDB cluster needs at least three nodes. Excuse me for my ignorance but why should I care about MyISAM compatibility? Can't I use InnoDB as I currently use (or actually was dictated by the guys who did the initial web application for us)? That doesn't mean you can't have an active-active database.

Google has also released some code for multimaster configurations and they have some docs also: http://code.google.com/p/mysql-master-master/ Thanks. I read about such a method (with 4 nodes) almost a year ago and thought that it might have become obsolate with MySQL cluster. Now I'll have to re-consider it. Regarding Postgres- I can't recommend anything specific but I am looking into pgpool and pgpool II for a new project. Why is pgpool relevant here? It more kind of a reverse proxy fo postgres in that it'll hide server failure by auto-connecting to another server. Does it handle data synchronisation as well? Another point which was just raised in the office - it appears that we are going to use DRBD for SQLite synchronization - if so then it should make sense to use DRBD for MySQL synchronization as well to reduce the configuration complexity. Any thoughts on that? I'm afraid that I'll have to convert my PostgresQL web service to use MySQL instead just to reduce the clutter...
