I'm using Postgres on Ubuntu 14.04 and I've been trying to import a csv file to a table in Postgres called 'weather'. I've looked at the question Postgres ERROR: could not open file for reading: Permission denied and tried using the \copy command instead of the regular copy, but I still get the same Permission Denied error. I'm somewhat hesitant to modify ownership permissions for all files for that directory for all the users (as suggested in the first answer). Here's the copy statement: \copy weather from '/home/user1/Dropbox/Development/Databases/SQL/Codeschool/TrySQL/temp_data.csv' HEADER

I created a amazon-web-services instance and used the Ubuntu 14.04 amazon machine image. now I can ssh into that machine and use the shell to run different commands. my question is now, how I can find out the public IP from that machine from inside that ssh-session? I tried using netstat and ifconfig but cannot find out the public IP I locked in with via ssh. Is there somebody who can tell me how to find out,

My native machine is ubuntu based 14.04 LTS x86_64 system, I want to cross-compile applications and QT programs for Beaglebone black, which is an armv7 based system running on Debian 2015 distribution. Which toolchain I should install on my native system, to get this done? Here is a very usefull link how to set up the crosscompiler, uboot, kernel and the filesystem for a beaglebone black. If you only want to crosscompiler, then just follow the few code lines in the Crosscompiler chapter https://eewiki.net/display/linuxonarm/BeagleBone+Black To cross-compile applications you need to use the '

trying to send UDP packets using Netcat nc -u 127.0.0.1 1234 And using tcpdump to see actual packets tcpdump -i any -vv -n udp dst port 1234 In theory the UDP packet size can be about 64K, however when I'm sending a message with size bigger than 2048 the Netcat splits the data and sends in 2 separate UDP packets. For example if I send the following long string

Hello I use a google cloud instance to run my codes, techonepl@instance-1:/opt/wpscan$ sudo gem install bundler && bundle install --without test Fetching: bundler-1.14.6.gem (100%) Successfully installed bundler-1.14.6 Parsing documentation for bundler-1.14.6 Installing ri documentation for bundler-1.14.6 Done installing documentation for bundler after 7 seconds 1 gem installed There was an error while trying to write to /opt/wpscan/.bundle/config . It is likely that you need to grant write permissions for that path. Even if I am running it using sudo, what else I need to grant? System info:

I launched an EC2 Spot Instance and unchecked the "Delete On Termination" option for the EBS root volume. I chose the Ubuntu 14.04 64-bit HVM AMI. At some point the instance got terminated due to max price and the EBS volume stayed behind as intended. Now eventually when the Spot Instance is relaunched it creates a brand-new EBS root volume. The old EBS root volume is still sitting out there. Actually I simulated the above events for testing purposes by manually terminating the Spot Instance and launching a new one, but I assume the result would be the same in real usage. So now, how can I get
