Detect new interface/nic without reboot

infoland
Hi,

We run Sophos UTM on a vSphere VM, if we add a new NIC/interface in vSphere you have to reboot the UTM to see the new interface. Is there a way of detecting it with a Linux command, so i don't have to reboot?

Thanks,

Freek

    You may try to run "setitfhw.plx". May I ask why reboot is not an option for hardware changes like this?

    Thanks, I will try that in our test environment. The problem is that we host several webapps behind this firewall, we want to create an active/passive cluster to avoid having problems with reboots in the future. For now a reboot is not conveniant, because we have to inform each customer, they have downtime etc...

    Even with HA you should inform your customers - what if sth. goes wrong or introduces a bug? Downtime maybe much longer, not just a reboot. Always make sure you have a scheduled update window when running in production.

    Hi trollvottel,

    what does setitfhw.plx do? I have a problem with a flexi modules not recognized by my  Webadmin (sg550 cluster nodes/9.355sw). Support also hasn´t an idea so far....

    The interfaces are shown in ethtool, even the portstatus, connected or not..... We already rebooted the maschines after the installation, but no change.

    Just ran through this adding flexiport modules to our SG430's in a HA setup. You HAVE to reboot. 

    The config is saved to the master. So you will need to shut down both. Add the module/interface to the master, boot up the master then boot up the slave.

    Invoking the linux command or doing them one at a time will only show up in the tech support section but not in the interface config.

    We did ours with about 5 mins of downtime.. and they are in separate buildings.

    Yes, trollvottel was an asset here for many years. We communicated offline in English and German.  Sometime after the Sophos acquisition, he left the company, but continued to contribute.  In one comment (out of hundreds!), he made a passing observation critical of Sophos' action on a specific issue.  Some young and overly-enthusiastic (I'm guessing) Sophos employee threatened him with legal action in a move that that person will regret as he matures.

    Trollvottel did what any honorable and emotionally-healthy person would do - he bowed out gracefully without naming the individual responsible for his decision to leave.

    Cheers - Bob
