Converting crt to PEM
Took two steps:
openssl x509 -in input.crt -out input.der -outform DER
openssl x509 -in input.der -inform DER -out output.pem -outform PEM
Using Nvidia propriety driver version 9755 allows using AIGLX instead of the slower and deprecated GLX interface. AIGLX nowadays is part of Xorg 7.1 and above. You can find a guide in OpenSuse Wiki which will describe the required actions. I have attached here my own xorg.conf file which allows Dual-head setup with 2 LCD…
Modern Kernel specification (can be seen here) defined the initial ramdisk (initrd or initramfs, depends on who you ask) to allow stacking of compressed or uncompressed CPIO archives. It means, in fact, that you can extend your current initramfs by appending a cpio.gz (or cpio) file at the end, containing the additions or changes to…
Assume a server has two network interfaces as follows: eth0 : 192.168.0.1/24 eth1 : 192.168.10.1/24 Let’s assume these interfaces reside on the different VLANs. Lets assume they were connected incorrectly, in such a way that eth0 is connected to VLAN 10, which servers 192.168.10.0/24 and eth1 is connected to VLAN 2, which serves 192.168.0.0/24. You…
I have been extremely busy for the last few weeks and couldn’t find time to update my blog, so apologies are in place. I am sorry, and I will add later this week several tips and tricks about BASH scripting, which might save time and effort for those of you who use if for more…
As part as my efforts of reducing the management overhead of multiple systems – much like the rest of the world – I am in a long process of migrating all my workload from virtual machines, each dedicated to a single or a small number of related services, to a container-based solutions. While containers are…
Unlike VMware Server, Xen’s HyperVisor does not allow an easy collection of performance information. The management machine, called “Domain-0” is actually a privileged virtual machine, and thus – get its own small share of CPUs and RAM. Collecting performance information on it will lead to, well, collecting performance information for a single VM, and not…
