Bought a Cisco Linksys WRT54G2 v1 Router

My wifi router was purchased one years ago, for some reason it’s not stable now, sometimes lost package when I ping it. After chat with my friends Steven, he recommended Cisco Linksys WRT54G2 which he is using, a very stable router. You can install DD-WRT firmware and leverage more new free feature, such as NFS, firewall, VPN…etc. I’m newbie, I’ll try explore more on my spare time. That’s a used router on120RMB (around $20).

I successfully installed it and turned on internet after 30 minutes, but I cannot log in my VPS by SSH on port 21, then I asked Steven’s VPS SSH to give a try, his port is 443, I cannot connect his also!! I suspected firewall on WRT54G2 maybe blocked the two ports since the router much like a Linux system, you can even run iptables command. Finally I figured out my network provider blocked port 21 and 443, how funny it is that I spend 3 hours to investigated firewall, routing table, wifi setting, NAT…etc. But forgot my sweet network provider!!


Error: No NIC found with MAC address…

Your HP server may runs fine on ESXi 4.x or 5.0, but you may get error message No NIC found with MAC address xx:xx:xx:xx:xx:xx after upgrade to ESXi 5.1 or later.

That’s caused by network adapter firmware, you have to upgrade server network adapter firmware by HP SPP 2013.02 or later. I would recommend you upgrade firmware of each component to this version, it’s pretty stable to run ESXi 5.1.

IPv6 link in NetApp SMVI backup log

NetApp Virtual Storage Console is my favorite to manage and backup data on NetApp attached ESXi host, there is lot of benefits to secure VM data more efficient.

The installation is pretty simple, and very less resource it requires, you can even install it on a multi-role virtual machine. But the first headache maybe the backup log.…

The default report URL is IPv6 in NetApp Virtual Storage Console. You have to add parameter in wrapper.conf file manually. Here is detail steps:

This procedure has to be repeated after NetApp Virtual Storage Console is upgraded.

1) Shut down SMVI server (via Windows service).

2) Open the wrapper.conf in C:\Program Files\NetApp\Virtual Storage Console\smvi\server\etc

3) Locate section
