I have a USB-stick (used as an installation medium). Now I need to install a driver from a restricted folder on that device). But how do I get the device path to my USB-stick (e.g. /dev/sda3 so I can mount it using the mount command?
I have read the answer to https://unix.stackexchange.com/questions/18925/how-to-mount-a-device-in-linux-beginners-confusion but fdisk -l shows nothing to me.
I have a new Mac Mini (MacMini6,1 late 2012) that I would like to install Ubuntu Server 13.04 (ubuntu-13.04-server-amd64+mac.iso) on. But it seems like Ubuntu Server isn't able to detect my network interface, because I get the message:
No network interfaces detected
How can I fix this issue? Is there any module or driver that I can add for this?
I have now tried to install Ubuntu Server with the build-essentials package and downloaded source to the tg3-driver as suggested in the answers. But when compiling (with the make command) I get errors:
...
cc1: some warnings being treated as errors
make[2]: *** [/home/jonas/tg3-3.129d/tg3.o] Error 1
make[1]: *** [_module_/home/jonas/tg3-3.129d] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-3.8.0-19-generic`
make: *** [default] Error 2
Any suggestions?
I'm used to work in Windows environment and are used to the commands in Notepad e.g. CtrlS for save, CtrlC for copy and so on.
On Ubuntu it's handy to work directly in the command line, e.g. as with vi mytextfile.txt.
I would like to use a text editor that I can use in the Terminal but with the same key commands as Notepad on Windows. Is there any text editor with "Notepad commands" for Ubuntu command line?
It's often that I need to locate the path to files and directories in Ubuntu Server. Are there any good way to search for files or directories in the filesystem by name?
I would like to use Jetty as a webserver.
I have edited the configuration file at /etc/default/jetty and set:
# change to 0 to allow Jetty start
NO_START=0
# Listen to connections from this network host
# Use 0.0.0.0 as host to accept all connections.
JETTY_HOST=0.0.0.0
Now I can reach the Jetty webserver at http://192.168.1.10:8080 but I would like to have Jetty listening on port 80.
I have tried this setting in the same configuration file:
# The network port used by Jetty
JETTY_PORT=80
and then restart Jetty with sudo service jetty restart but it doesn't work.
How can I change so that the Jetty webserver is listening on port 80?
I use Ubuntu 9.04 (the most recent version that the VPS host provided) on a Xen VPS. The kernel version seem to be something Xen-specific: 2.6.18-194.32.1.el5xen.
I would like to have the most recent version of Ubuntu Server, 10.10. Can I upgrade my VPS to 10.10 or do I need to stay with this version because it seem to be a Xen-specific kernel?
I have a VPS with Ubuntu Server 10.10 x64.
I tried to install Java using apt-get install openjdk-6-jre but that fails, see ca-certificates-java fails to install.
Now I would like to install PHP with sudo apt-get install nginx php5-fpm php-apc php5-pgsql php5-suhosin but that also fails, with the same error message as I had with Java. Why is that? How can I install other applications now after the installation of Java has failed?
I use a VPS with Ubuntu Server 10.10 x64. I want to use Java and run the command sudo apt-get install openjdk-6-jre but it fails because the installation encounted errors while processing ca-certificates-java.
I have tried to install the failed package with:
sudo apt-get install ca-certificates-java
How can I solve this?
I have run sudo apt-get update and sudo apt-get upgrade but I get the same errors after that.
I have also installed Ubuntu Server x64 on a VirtualBox, but the two Ubuntu Server 10.10 has different kernel versions (2.6.35 on VirtualBox and 2.6.18 on my VPS). And on VirtualBox I can install Jetty without any problems.
The VPS is a fresh install of Ubuntu Server 10.10 x64, the first command I was running was sudo apt-get install openjdk-6-jre.
When I run sudo apt-get install ca-certificates-java I get this message:
Reading package lists... Done
Building dependency tree
Reading state information... Done
ca-certificates-java is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
1 not fully installed or removed.
After this operation, 0B of additional disk space will be used.
Do you want to continue [Y/n]?
Here I press Y then I get this message:

Update
I also get a problem when running java -version:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
My VPS had 128MB of Memory, I changed to 256MB but got the same problem. Then I changed to 512MB and got the same problem.
I found a related post on a forum: Sub-process /usr/bin/dpkg returned an error code (1) And I tried:
sudo apt-get clean
sudo apt-get --reinstall install openjdk-6-jre
sudo dpkg --configure -a
But I got the same problem, even when I'm using 512MB of Memory.
Any suggestions?
Update 2:
I have now created a new VPS with 512MB and Ubuntu Server 10.04 LTS x64 and run these commands:
sudo apt-get update sudo apt-get upgrade sudo apt-get install openjdk-6-jre
But I got the same error messages. If I do the same thing in VirtualBox everything works fine.
Is there a command to see who owns a specific Internet domain address?
I have tried with whois example.com and I get some information. But for "holder" there is just a "user ID". Is there any way to see who the actual user is?
I have used top to see the memory usage at the moment. But I would like to monitor the memory usage over a period of time. E.g start monitoring and then execute a few commands, and final stop the monitoring and see how much memory that have been used during the period.
How can I do this on Ubuntu Server?
I guess I could start a cronjob every 5th second or so, and invoke a command that log the current memory usage in a textfile. But what command should I use to get the current memory usage in a format that is easy to log to a text file?
I use Ubuntu Server 10.10 and have installed Nginx web server with apt-get install nginx. It creates a default web page at /var/www/nginx-default/ and that directory has the permissions drwxr-xr-x 2 root root.
When I access the default site on http://localhost/ I get this message on the page 403 Forbidden.
How should I set the file permissions on the www root so I can secure access the web pages? Or is there something else that I have to change?
I run Ubuntu Server 10.10 in VirtualBox with Windows as host. Accidently I choosed to generate a new random MAC-address for my Ubuntu machine in VirtualBox. And now when I have booted my Ubuntu with the new MAC-address, I don't get an external IP-address. I'm using DHCP to get IP-addresses.
I guess I have to run a command and inform my Ubuntu system that the MAC-address has changed to get an external IP-address.
If I execute sudo /etc/init.d/networking restart I get this message:
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
eth0: ERROR while getting interface flags: No such device
Bind socket to interface: No such device
Failed to bring up eth0
How can I solve this?
I would like to see what ports are open on my machine, e.g. what ports my machine is listening on. E.g. port 80 if I have installed a web server, and so on.
Is there any command for this?
I use Ubuntu Server 10.10 and I would like to set up a web server environment with NginX, PHP 5.3.3, PostgreSQL and preferably APC and PHP Suhosin.
I have already set up PostgreSQL with apt-get install postgresql and Nginx with apt-get install nginx.
But how do I set up PHP for these? Can I do this using apt-get install or do I have to download the sources and compile it? I would prefer to do it using apt-get.
I would likte to use PHP-FPM for Nginx. Most of the tutorials I have found on Internet are old and compile the PHP, but this is not recommended for production servers.
How do I easiest set up PHP with Nginx, APC and PostgreSQL? or at least PHP-FPM + Nginx?
UPDATE
I have now installed a fresh Ubuntu Server 10.10 and executed the command Peter suggested with php5-suhosin added. After that Nginx works fine, then I edit the generated confiugration file to be as below. After reloading the new config file, Nginx still works fine using a index.html file, but when I add a index.php file it stop to work. I guess that this has to do with PHP-FPM, the APC or something PHP-related. But it could be the configuration file for PHP-FPM as well.
Here is the configuration file for Nginx that I'm using, most of it is generated by default. I have skipped comments.
server {
listen 80;
listen [::]:80 default ipv6only=on;
server_name localhost;
access_log /var/log/nginx/localhost.access.log;
location /favicon.ico {
empty_gif;
}
location / {
root /var/www;
index index.php index.html index.htm;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
}
I would like to know how software updates work for my Ubuntu Server 10.10.
I have been recommended to use apt-get install for installing new software and apt-get update for updating software for a Ubuntu Server in production use. Because these packages are tested for Ubuntu in contrast to download source code and compile the software on the box.
But on my Ubuntu Server 10.10, I don't get the latest stable version of PostgreSQL (9) or the latest stable version of Nginx (8) using apt-get install. So how is this working, will these software be updated when I later run apt-get update or do I have to later run apt-get install again, or do I have to wait for the next release of Ubuntu to get them?
And are patches and security updates managed in the same way? Or can they be updated automatically? If there is such a setting, how do I check what my system is using?
