Enable sFTP on Synology DS409slim
Synology is kind enough to allow remote SSH connection to their NAS. I have enabled it on my DS409slim. But there is just one little missing feature: sFTP ; that is transfer file via SSH.
To enable sFTP with DSM 4.0, log on the Synology using SSH, manually enable the sftp subsystem and restart the SSH dæmon:
# vi /etc/ssh/sshd_config (...) Subsystem sftp internal-sftp -f DAEMON -l VERBOSE (...) # /usr/syno/etc/rc.d/S95sshd.sh restart Stop SSH... Connection to syno closed by remote host.
Unfortunately, that last command never restarted the SSH daemon… Just log on the Web interface, browse to the configuration panel and, from the “Terminal” section, select “Enable the SSH service”. This will restart the SSH dæmon and give you access to sFTP transfer too.
OpenBSD 5.1 on Sun Fire V100
A long time ago, in a galaxy not so far away, TuM’Fatig ran on a Sun Fire V100. One day it was pluggued off for some apartment move and was never powered on again.
Today is the day when it is powered on again to run OpenBSD 5.1.
OpenBSD 5.1 on Sun Ultra 5
It’s been a while since I owned a Sun Ultra 5, back to 2002. It has run many OS, mostly BSD flavoured, and served me well in many cases. It has been tweaked a bit: add a Quad HME card, replace the CD-ROM by a CD-RW burner and replace the fan and PSU by silent PC parts.
I’ve just powered it on and it is indeed quite silent. I really would like to use it again… if it wasn’t needing 61 Watts (more than a Mac Mini G4). So here we are, a last OpenBSD install before I find a new home for it.
Choosing between AMD and Intel for the Virtual Infrastructure
My ESXi v5 runs on a Mini-ITX Z68 motherboard with Intel Core i5 2500T (Quad core). I choose this because I wanted to have a silent (fanless) and low consumption box. The box runs quite well. The only thing that I regret is that I don’t have access to any sensors from the vSphere client. I was looking at the SuperMicro motherboards as they seem to provide IPMI.
The SuperMicro H8SCM-F looked really really nice. Micro ATX Form, integrated IPMI and KVM, support for up to 128GB of RAM and AMD Opteron 4000 Series ; the Opteron 4256 EE @2.5 GHz have 8 cores and a TDP of 35W! So I started to wonder how whould an Opteron 4256 EE (8 cores, 2,5GHz, 35W TDP) performs vs my Core i5 2500T (4 cores, 2,3GHz, 45W TDP). According to SPECfp2006 Rate Results, the AMD Opteron 4256 EE would have a baseline of 67 and the Intel Core i5-2500T would have a baseline of 87. A better comparison should be done with Opteron 3250 HE (4 cores, 2,5GHz, 45W TDP) which is ranked 52.
Then the big question raised: is it better to choose AMD or Intel for the virtual infrastructure. I recall reading than AMD processor were perfect for virtualization because they have more cores and use less power. But this was the marketing chat and was published a year ago. What I’m going to do here is try to understand how to compare processor in the case of hypervisor.
Install a 1.8″ SSD in an EeePC 900 via ZIF adapter
I have an EeePC 900 that does nothing for a long time now. My mother asked me for a laptop that she would travel with ; just for reading emails and surfing the Web. That sounds perfect for this machine. I initially planned to install Windows 7 on it so that it’s the same OS than on her workstation PC. The 8GB internal SSD is really to small to run Windows 7 (even running XP is annoying because of Windows Updates) so I decided to install a 1.8″ SSD using a ZIF adapter.
Here’s how I did it.
