IDS 4.1 hangs regularly

Dear All,

I have IDS sensor 4230, I lately upgraded from 3.1 to 4.1 , and since the upgrade I faced a problem that every few days the sensor hangs. It doesn't respond to telnet,https, or even console login through console or monitor, and all I can do is reset it. This never happened with the 3.1 version. Here is the output of the show version command on the sensor :


sensor# sh ver

Re: IDS 4.1 hangs regularly

I think what you are seeing is known problem documented as CSCed54146 bug. In brief here is the detail :

Problem: sensor command and control unresponsive except for ping.

Symptom: cannot ssh, telnet, connect using IDM or other management tool.

sensor needs to be rebooted to regain access.

Workaround: Install latest patches: 4.1(3e).

As root: issue the command: swapoff -a.

This will need to be done each time the sensor reboots.

There will be a new 4.1(5) release to address this issue, but it will be at least May 2004 before this is ready.

For more details you can access the bug on via bug toolkit.

Re: IDS 4.1 hangs regularly

Thanks for your help sir, I guess this is the problem but I have two questions:

1- Where to download the 4.1(3e) patch? I dont see it in the IDS upgrade page.

2- How to login as root? does it have a default password?

Re: IDS 4.1 hangs regularly

You need to contact the TAC to get access to the 4.1(3e) patch.

They will also instruct you on how to use the service account to get root access and make the additional modifications.

Re: IDS 4.1 hangs regularly


i got the error message :

IDS-K9-patch-4.1-3e.rpm.pkg: read manifest failed: Success

so after installing the patch, i am still require to run "swapoff -a" after every reboot ?

Re: IDS 4.1 hangs regularly

What's the status of 4.1(5) release? Will it be released on time?

We were forced to upgrade our IDS-4230 from 3.1 to 4.1 in order to get new signature updates. Now, we're experiencing this lockup condition that we did not experience with the SunOS 3.1 software. We're also experiencing this issue with our IDS-4215.
