I’ll document my experiences with SynergyCP on my blog to help future network- and sysadmins with their SyCP mishaps.
Public IPs have been replaced with TEST-NET equivalents for obvious reasons. Enjoy! I have a rather nice ISP which allows me to use two public IPv4 addresses: one is dynamic and routed through their gateway at 192.168.64.1 and the other one is static, bridged directly to the internet through an extra port on the modem.

Firewalls aren’t as special as they’re made out to be in the business sphere. Sometimes salesmen will try to convince you otherwise, claiming their network appliances use application specific hardware, but teardowns often disappoint. This teardown of the IBM Proventia GX4004 is no different, as the firewall appliance turns out to be a very ordinary […]
As smartphones came to be, many common portable devices such as netbooks, palmtops and pocket organizers became obsolete. Today I will present to you one such device – a Tidalwave palmtop computer from 1992.
A really quick post to help others that encountered the same problem as me. The iLO 100 remote management system on the HP ProLiant ML110 G6 server can’t be password reset with a jumper or a similarly simple measure. It involves a DOS boot disk and a certain ipmitool command that resets the username “admin” […]
In the previous part, we set up DHCP, TFTP and RARP servers and successfully booted the OpenBSD ramdisk install kernel on old Soekris hardware over the network from a repurposed Cisco IDS. In the last part of this series, we will add NFS shares to the mix and install OpenBSD to them, making our PXE […]
In the first part, we became familiar with the hardware we’ll be working on and gathered the needed information. In this part, we focus on making PXE work up to the point we’re able to get to the boot loader and load a kernel.
Does anyone remember Soekris Engineering, the company that made network hardware and somehow also audiophile equipment? The first part of the company has unfortunately closed down in April 2017, while the latter still persists today. However, we won’t be focusing on high-fidelity audio in this guide, but rather on squeezing the last bits of life […]
Even though Cisco equipment is very capable, it tends to become End-of-Life before you can say “planned obsolescence”. Websites become bigger, bandwidths increase, and as a side effect of those “improvements”, routers, firewalls, and in this case, intrusion prevention systems get old quicker and quicker. Apparently, this was also the case for the Cisco IDS-4215 […]
