Just a report did the upgrade to current ispconfig and mail stopped flowing - dug into it and found the dovecot conf file pointing to the wrong place is still there. fixed it with the ln commands: ln -s /etc/dovecot/dovecot-sql.conf /etc/dovecot-sql.conf ln -s /etc/dovecot/dovecot.conf /etc/dovecot.conf but I had thought you would want to fix the upgrade script and second - I just got a Linode running Centos6.5 and (OBVIOUSLY) want to get it configured perfectly and with ISPConfig3. I want to manage both from my main server. I dont guess you would have any Linode specific tutorials? and a suggestion - maybe Linode should have a Centos6.5 image with ISPConfig3 already installed somewhere? your product is outstanding. are they aware of you? I would Love to see a 'Centos6.5 w/ISPConfig' choice in the pulldown. and one more question - I'm trying to get to the bottom of a performance issue - one server running ngnix and my main running apache2. a php loop that takes 10 seconds on one takes two+ minutes on the other running on the same mongo database. the mongo is not the issue (search takes well under 1 second) it looks like its Jquery loading the screen prior to display thats killing the one server. Oddly this was very surprising as MY server is the slow one and I've got 32gb of ram and 2 hexacore opterons. The other is just a linode running ubuntu - but it is using ngnix. could THAT make that much of a difference? and anyway to test it? and (holding breath) can I install ngnix on my server as well as apache2 and have them coexist? inquiring minds and all that. keep up (as always) the great work.
