  • Cisco Unified Communications Manager 12 Install Errors on Proxmox/KVM


    The strange thing is that usually the first install or two will work on any new machine but then it suddenly won't. I had this experience on QEMU 2.13 on a different machine. There is something finicky or buggy about the CUCM installer even when choosing the same virtual hardware specs. qemu-kvm command: /usr/libexec/qemu-kvm -version QEMU PC emulator version 0.12.1 (qemu-kvm-0.12.1.2-2.506.el6_10.1), Copyright (c) 2003-2008 Fabrice Bellard ........

  • tsclient (Terminal Server RDP Client) missing in Debian, Ubuntu, Linux Mint


    This was a horrible shock after upgrading fromUbuntu 9 to Linux Mint 17 and I found that the last distro to support tsclient was Debian Squeeze.

Fortunately there is a solution: tsclient surprisingly can be downloaded as a direct .deb package and it fails with some variou........
