  1. I've seen ISPs and web host providers to limit the speed of downloads. 100kbps sounds to be very slow alright. I'd advise testing with another client computer and see what speeds they get at. It could be your ISP, or the web host provider. I've seen this before and have had to use a muti-threaded downloader to get full download speed.
  2. Are you sure its not just the web client doing the caching? By default apache shouldn't cache anything. I suggest you use a number of different browsers (opera, chrome, firefox, ie) and delete any temporary internet files often. -steve
  3. what does the following show: netstat -tap what does the following show: iptables -L -steve
  4. I take it there is no firewall involved? I see you done a nmap. Can you do a telnet yourdomain 443 from a remote computer and see if port 443 is open. If I were you'd I'd go back to setting up a self-signed ssl cert and get that working first. Although its not for fedora take a look at: http://wiki.kartbuilding.net/index.php/Apache_2_%26_SSL_-_PHP4_-_MySQL_4.1 exerpt of what you need to try: mkdir /etc/apache2/ssl cd /etc/apache2/ssl openssl req -x509 -days 365 -newkey rsa:1024 -keyout hostkey.pem -nodes -out hostcert.pem cat hostkey.pem >> hostcert.pem mv hostcert.pem apache.pem <VirtualHost *:443> //insert code as Normal; same as above SSLEngine On SSLCertificateFile /etc/apache2/ssl/apache.pem </VirtualHost> -steve
  5. Can you do the following test: telnet ipaddress 80 I know you said you checked the firewall, but I'd check again. Do a "netstat -tapn" on the server and check to see if apache is actually running and if it is using port 80. -steve
  6. How about something as simple as the following in a crontab: ./script1.sh && ./script2.sh Script 2 will wait until script 1 finishes. -steve
  7. You could use frames, but they are messy. -steve
  8. And does ping iphone.admin.yoursite.com work? If so, it sounds more like the webspace setup side and permissions. What control panel do you use for setting up web accounts and web space etc?
  9. I suggest you get a low power server with efficient hard drives to keep electricity usage down. Old servers and HDDs chew up electricity. *steviewdr has a daily rsync to a 1TB external usb drive. -steve
  10. Yes of course. You need to set your dns firstly. If you have a dns control panel, login and add a sub domain. However type "iphone.admin" in. It should be respected. Then after you save, try and go ping iphone.admin.yoursite.com. Note it could take a few min for dns to update. -steve
  11. You should be logging mysql slow queries. Add or uncomment the following line in your my.cnf: log-slow-queries = /var/log/mysql/mysql-slow.log Then watch that file. As I mentioned earlier, munin would be very very useful. It will graph for you mysql connections in a 5 minute period. -steve
  12. I don't see any issues. I don't think you will require a separate mailserver. Just make sure its setup properly. You'll want to keep an eye on RBLs for your mail server. http://en.wikipedia.org/wiki/DNSBL I don't forsee an ISP blocking your mail server, unless you are sending spam emails or if they hit a honeypot. If you keep an eye on your mail.info log, you can see if emails are bounced back and if so, what message/error is bounced. -steve
  13. If you think it could be mysql, then this could quite possibly be the case. Google for mysqltuner.pl and mysqlreport. These scripts will report mysql slow queries and if you have enough memory set for mysql in mysql.cnf. I HIGHLY recommend you install munin and munin-node. There are centos, debian packages etc. etc. See: http://brage.sunsite.dk/munin/dotsrc.org/munin.dotsrc.org.html http://www.gnegg.ch/2009/01/monitoring-servers-with-munin/ -steve
  14. See: http://wiki.kartbuilding.net/index.php/Apache#mod_evasive To prevent the db server from falling over, I suggest you limit the number of connections allowed from a mysql user. I limited mine to 10 simultaneous connections per user. This helped a LOT. In my case the db server didn't fall over, and after a few minutes sorted itself out. I also suggest you look at what web pages are accessed and what mysql queries are been made. It could be the type of mysql query been made. Also did you see if there are any mysql slow queries? (assuming your using mysql). -steve
  15. mark: rsync has --inplace and --partial switches which can pick up transferring large files from where it left off. -steve
