comment Rsync - resending all files, because files have different timestamp (off by 1 second!)
Brilliant. --modify-window - When comparing two timestamps, rsync treats the timestamps as being equal if they differ by no more than the modify-window value. This is normally 0 (for an exact match), but you may find it useful to set this to a larger value in some situations. In particular, when transferring to or from an MS Windows FAT filesystem (which represents times with a 2-second resolution), --modify-window=1 is useful (allowing times to differ by up to 1 second).

comment Cannot access webserver on virtual machine from the internet
Apparently, I shouldn't delete the Nat adapter because I am using Vagrant. Commands like "vagrant up" won't work if the Nat adapter is removed. So mine might not be the best solution.

comment VPN to work from another continent?
#1 is a fair point, although I try to access external sites using another computer w/o the VPN, or turn the VPN off. However, there's no way around this problem that I know of if I have to access work data at another site far away from the VPN location, and I am also far away from the VPN. Or, regardless of source location, if I want the data to travel through the VPN for security reasons.

comment Why is using VPN can increase my speedtest result?
This is the right answer, and should have been accepted as such.

I only see rejects related to icmp. This is a newly installed centos 7 distro.

comment Can ssh but can't access webserver
What am I looking for with iptables -L? I see lots of ACCEPT but I also see REJECT. I followed this guide to turn off the firewall:shellhacks.com/en/…

comment Can't connect to Virtualbox web server (using Bridged Network)
Sorry for bringing this up again, but I have a similar problem. What am I looking for when I do iptables -L? I see ACCEPT and a few REJECT. However, following this page, I thought I had turned off my firewall completely. shellhacks.com/en/…

comment Does overclocking have any benefit on a processor that already has Intel Turbo Boost?
depends on how much you want to overclock and how much the turbo boost raises the clock speed to, and if there is a limit and delay on it.

comment VirtualBox: ifconfig does not show my ip address
if adapter 1,2,3,4 does not matter, how does VirtualBox know which adapter on the VM side to bridge? e.g. enp0s3 vs. virbr0.

comment VirtualBox: ifconfig does not show my ip address
Right now it is on VirtualBox: Adapter 2, Bridged Adapter, Wireless LAN PCI (the right one I use on my host), Deny promiscuous mode, and cable connected.

comment Cannot access webserver on virtual machine from the internet
I found what the problem was. Virtualbox creates two adapters, one NAT, supposedly for the ssh connection, and the bridged adapter that I asked for. If I disable the NAT adapter (ie. through VirtualBox), suddenly it works, and I can access the webserver from the internet. If I leave the NAT adapter in, I can only access the webserver from within my network (ie. other boxes). I'll do a writeup with screenshots in the answer.

@xR34P3Rx, I'll write up a more detailed summary of what I did tonight.

comment Cannot access webserver on virtual machine from the internet
Not sure if this is a issue, but when I try to look at my "wireless clients" list on Airport, I cannot see my bridged VM (static IP). When I was using the wrt-54g, the most similar list I could find was the dhcp client list, which did not show the VM as well. Not sure if it would show up in the latter case as the VM has a static IP.

@xR34P3Rx, I have tried both, but to no avail.

@maudam, yes. Accessing from the host's browser works.

comment Cannot access webserver on virtual machine from the internet
@janos, yes, but I also move the webserver from host to vm when i test the vm_ip, and vice versa.
