I am getting notices that a RedHAT server of mine is probing other networks. I need some advice on how to prevent this and find out what is occurring.The message info I received is below. I have since made sure the firewall is running and unnecessary ports including ftp are off. Any help to get on top of this would be greatly appreciated. I am fairly new, so please be specific. >Mar 4 02:50:27 x.x.x.x:21 -> x.156.3.21:21 SYN ******S* >Mar 4 02:50:27 x.x.x.x:21 -> x.156.3.22:21 SYN ******S* >Mar 4 02:50:27 x.x.x.x:21 -> x.156.3.23:21 SYN ******S* >Mar 4 02:50:27 x.x.x.x:21 -> x.156.3.30:21 SYN ******S* >Mar 4 02:50:27 x.x.x.x:21 -> x.156.3.32:21 SYN ******S* >Mar 4 02:50:27 x.x.x.x:21 -> x.156.3.37:21 SYN ******S* >Mar 4 02:50:27 x.x.x.x:21 -> x.156.3.38:21 SYN ******S* -- Raymond Norton Little Crow Telemedia Network 320-234-0270
