In my post just below, I have defined a set of tests to verify the possible cause of the tg3 problem. It had nothing to do with autoneg, and was fixed in RHEL 4 Update 4. That 32bit installer works correctly. One last thing to test – rebuild the installer initrd, and replace tg3 module…
Here are some pictures of the server upgrade. Old server: P2 300MHz, with 256MB RAM: Old server, in its old location New server: Xion 3GHz+HT+EMT64, with 1GB RAM. Nice: Dell PowerEdge 1800. Nice LEDs 
The whole server room during the upgrade. Notice the 3com router/switch! You’ll be able to recognise it by its antenas…
I find it that identifying a missing something in the fridge, and adding it to a list does not work well for me. It’s either that I take a mental note of the missing groceries, and then, almost immediately, forget them until the unpacking of the just-purchased groceries, back home, several days later, or that…
Performance tuning is a sort of art. You know what you expect to reach, and you somehow strive towards that through selective tuning. Either your OS memory utilization, your network settings, NFS mount parameters, etc. I’ve been to a customer who’s server acted funny. First, it had high load average – for an idle server…
When I’ve created my setup (displayed below), I took into account the possibility of disconnection, or process fall, and I’ve left pppd to deal with it, by trying to connect just as it has fallen down. It was a good solution for the scenarios where there is a temporary, short timed disconnection. It fails to…
This is a bit on the less legit side, but a need rose where I was required to update the BIOS on an old SuperMicro SBB server. The thing is – the IPMI, which is fully capable otherwise, did not allow me to update the BIOS using this interface, and the other options were using…
