I have the following problem. But I only have ssh access to the Mac machine. So I not use any GUI solution. Is there a way to enable this in the command line? Thanks.
I see this error message in the log of msmtp. What does it mean? How to fix the problem?
I previous used tor's socks proxy and I don't see this message. But when I switch the proxy to a shadowsocks localhost port, I see this error.
I don't find a way to set up split tunneling.
I basically need to use VPN to access certain websites behind a firewall and not to use VPN for anything not in the firewall. With Cisco AnyConnect Secure Mobility Client, I can either use the VPN or not to use it. I don't see a way to set for what domains and IP addresses to use VPN and for what domains and IP addresses not to use VPN.
It seems that my Cisco AnyConnect Secure Mobility Client is a customized version by my administrator (I am not quite sure. Can an administrator customize the software so that it will disable split tunneling?)
In that case, is there no way to set up split tunneling on Mac OS X while the VPN is on?
I have the following line in the Dockerfile.
RUN apt-get install -y tzdata
When I run it, it asks for my input. After I provided my input, it hung there. Does anybody know how to solve this problem?

How to open a 8080 port for an application, with iptables
I see the above thread. And I run the following commands. But it seems that 8080 is still accessible outside the machine. Does anybody know what is wrong?
$ netstat -tanpu | grep ":8080"
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

The following is the price of the 4TB NL-SAS drive offered by Dell for PowerEdge 720xd.
4TB 7.2K RPM Near-Line SAS 6Gbps 3.5in Hot-plug Hard Drive [$663.38]
It seems to be too expensive. A similar drive is much cheaper (only ~ $300) on amazon.
Does anybody know whether the Seagate Drive from amaozon is considered as NL-SAS drive? If so, why there is such a huge difference in terms of price.
Also, if so, is it common to only purchase the minimal number of disks from Dell and purchase HDD from other venders and add these disks to the RAID later?
I'm considering the following RAID controllers. Do all of them allow me to add HDD later (or rebuild the RAID from scratch)? Thanks.
