Hello list, |
2 |
|
3 |
This morning I noticed that my machine was frozen (would not respond to |
4 |
keyboard or mouse, so couldn't ctrl+alt+func_key to a terminal or anything, |
5 |
I couldn't ping it either). I reset it and started chugging along... or so I |
6 |
thought. This machine is my firewall. Everytime a client attempts to connect |
7 |
to eth1, the machine crashes. Prior to the most recent crash I switched to a |
8 |
console session so I could see messages coming to the screen and I saw |
9 |
something to the tune of: |
10 |
|
11 |

=============== |

|
25 |
I can induce the crash at will by: |
26 |
|
27 |
1. booting the firewall |
28 |
2. booting the client that is connected to eth1 |
29 |
|
30 |
or |
31 |
|
32 |
(if the client is booted) |
33 |
1. boot the firewall |
34 |
2. disconnect the cable that is plugged into eth1 and plug it into eth2 |
35 |
|
36 |
(if the client is booted) |
37 |
1. boot the firewall |
38 |
2. change the ip parameters on the client and ping the firewall |
39 |

I'm running 2.6.19-r1. I've been using that kernel for probably 1 month or |
41 |
so. The most recent change I made to the machine was installing Shorewall |
42 |
and recompiling the kernel to add the ip masq stuff. The machine ran all |
43 |
weekend with no hitches. Last night my wife's laptop was connected to eth1 |
44 |
and she was surfing the net just fine, I disconnected her laptop and |
45 |
connected my laptop and I surfed the net just fine. I woke up this morning |
46 |
and noticed this trouble? |
47 |
|
48 |
Have any of yous guys seen anything like this before? |

Thanks, |
