Linuxshield (1.9.1) : OAS disabled

Jump to solution

Hello,

We have VSEL 1.9.0 installed on our servers.  After an upgrade to version 1.9.1 (via Product Deployment Tasl through the ePO), the version indeed changed to 1.9.1 but however the OAS is disabled.

While we tried to enable the OAS, we got the following error:

[root@Centsrv004 VSEL_190]# /opt/NAI/LinuxShield/bin/nails on-access -e

reload failed code Failed to attach to the kernel

[root@Centsrv004 VSEL_190]#

Can someone please help me out with this?

Thanking you in advance.

Regards,

Azhar

Hello,

The issue is finally resolved.

1) in some cases a simple reboot fix the issue

2) Other cases:
Actually some of our servers were patched recently and it seemed that the Kernel also was upgraded. so to resolve the issue, we uninstall the VSEL as well as the agent, reboot the server and install it afresh. [it seemed that the root cause of this issue was that the Kernel needs to be recompiled in order to work correctly with the OAS module]

While launching the command:

/opt/NAI/Linuxshield/bin/nails on-access -s | the OAS was finally up and running

I resolve this discussion thank you for your help

regards,

M.
