Application Filtering Software Firewall for Linux? (i.e. Kerio, ZoneAlarm... 4 Linux)
There are a lot of great application filtering firewalls for windows. Kerio and ZoneAlarmPro (newer ZAfree versions do poorly) come to mind though there are other that are truely excellent like Look'nStop and Jetico.
Are there any application filtering firewalls for Linux? I like to control program access too, not just open and close ports. I'm currently useing GuardDog in KDE, but I consider that just a stopgap until I find something better.
FYI If you're looking for a great firewall-related site, check out www.firewallleaktester.com. All the apps there are WinOS though. Found out about them just recently from <this> eweek article.
