Network between two ubuntu 16 on VirtualBox

Oba22

I'm trying to build a seat between two virtuals. To that end, he added an additional adapter in VB structures with the Internal Network parameter. Then edited file /etc/network/interfaces like:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto eth0
iface eth0 inet dhcp
auto eth1
iface eth1 inet static
address 192.168.0.1
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255

Now, in an attempt to reboot the online demana, I have a mistake:

[....] Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code. See "systemctl status networking.service" and "journalctl -xe" for details.

I tried to reboot the car and do it. ifconfigip didn't change that. What am I doing wrong?

You can just make a grid bridge in the building of all the virtois and they'll be on the same grid with the host. DHCP will also be from the Router.

I solved it the following way:Cancel the error and open the program.Makes mistake with the jdk route. I thought that wasn't the solution, but as in other similar questions I go to Project Settings.I locate my jdk with the command sudo update-alternatives --config javaThere are 2 options for the java alternative (which provides /usr/bin/java).0 /usr/lib/jvm/java-8-oracle/jre/bin/java 10811 /usr/lib/jvm/java-8-openjdk-i386/jre/bin/java 1081* 2 /usr/lib/jvm/java-8-oracle/jre/bin/java 1081 and in project settings the default path of jdk is replaced by:/usr/lib/jvm/java-8-oracleThis way the graddle synchronization works and it works, so I think the problem is solved.

Try to set the standard Python as the 3.5. using the command:sudo ln -sf /usr/bin/python3.5 /usr/bin/python3 If this doesn't work, you can reinstall packages from python3 using the command:sudo apt-get install --reinstall python3 If it still doesn't work, remove all packages python the update-alternatives and define Python ♪ as default using the commands:sudo update-alternatives --remove-all python sudo ln -sf /usr/bin/python2.7 /usr/bin/python

In conclusion, if you open Vim, you can edit it directly.It is the difference between the reason why it is.echo "export PATH=$PYENV_ROOT/bin:$PATH" >> ~/.bashrc In this case, if there is a variable in the string enclosed with a double quote, it will be expanded.However, in this stage$PYENV_ROOTis not defined.CommentechoIf you want to add a double quoted string, you need to prevent the variable from being expanded.echo 'export PATH=$PYENV_ROOT/bin:$PATH' >> ~/.bashrc On the other hand, the variable is not expanded in a single quote, and it is added as it is.

This declaration of a two-air mass as a parametervoid ArrFill(int arr[][], int rows, int cols) ^^^^^^^^^^^ Uncorrect.All sizes of the mass other than the extreme left shall be specified and constant. C++ also does not support variable lengths.You could declare the function as follows:const size_t Cols = /*...*/; void ArrFill( int arr[][Cols], size_t rows ); Besides, the symbol is not that symbol. '/t'And this symbol '\t'♪You can make life much easier if you declare a shabby function of the species.template <size_t Rows, size_t Cols> void ArrFill( int ( &arr )[Rows][Cols], std::pair<int, int> range ) { std::srand( std::time( nullptr ) ); for ( auto &row : arr ) { for ( auto &item : row ) { item = range.first + std::rand() % ( range.second - range.first ); std::cout << item << '\t'; } std::cout << '\n'; } } For example,#include <iostream> #include <utility> #include <cstdlib> #include <ctime> template <size_t Rows, size_t Cols> void ArrFill( int ( &arr )[Rows][Cols], std::pair<int, int> range ) { std::srand( std::time( nullptr ) ); for ( auto &row : arr ) { for ( auto &item : row ) { item = range.first + std::rand() % ( range.second - range.first ); std::cout << item << '\t'; } std::cout << '\n'; } } int main() { const size_t Rows = 10, Cols = 10; int arr[Rows][Cols]; ArrFill( arr, { 30, 90 } ); return 0; } The conclusion of the programme to console may, for example, be as follows:84 44 65 61 72 62 87 30 88 72 84 85 72 49 46 63 67 71 37 35 73 32 49 57 61 63 47 64 67 76 81 53 30 48 84 73 80 82 65 71 56 60 66 38 71 74 63 40 56 62 45 31 64 56 50 35 30 67 62 59 53 45 82 54 64 76 89 46 60 64 87 86 86 55 86 68 40 59 78 58 31 86 59 58 52 79 63 44 49 87 73 72 43 65 88 77 44 87 33 74

/users/1155/iranda , please add dmesg , grep b43After that, you can try the next teams.sudo apt-get remove --purge bcmwl-kernel-sourcesudo apt-get install b43-fwcuttersudo apt-get install firmware-b43-installerAnd then reboot. It's all for wireless. I have to go now. We'll see the rest later. :They also say that the problem disappears with the kernel above 3.1 rc3. Again, you can download all the necessary packages on another PC with this violin: http://paste.org.ru/?as3sru You can use it to download bags above.python grabpackages.py -o downloader_script b43-fwcutter firmware-b43-installer.

"do you think adding an index in the column item_t0.TargetPK will optimize the queries, as it is the one who is changing value from query to another ?" That is a bad reason for indexing. What matters is how much the index will help reduce the amount of work required to compute the query. Whether your proposed index will help will mostly depend on which of these results is larger: select count(*) from product2division item_t0 where item_t0.Qualifier = 'Product2Division' select count(*) from product2division item_t0 where item_t0.TargetPK = 8799116853249 Assuming there is even distribution of TargetPk values. If TargetPK is unqique then the second query will always return 1 (or zero) which means there will only be a maximum of 1 row to look at in the table which is great. Of course, if the difference is small then the decider will be down to how clustered the rows that match these filters are. If both counts are relatively high, then maybe a composite index which includes both columns could be a good idea (if there's not a lot of crossover on the rows that each filter finds). Another possibility is that you could drive the query from the division table. This could be sensible if the TypePkString is going to return a small amount of rows and the SourcePK filter (from the join) is also relatively good at reducing the number of rows visited in product2division. For this order of tables, you would be indexing: division (TypePkString) product2division (SourcePK)

Don't go deep in the suburbs. /usr/share/X11/xkb/symbols/, for such a small task, opportunities can be exploited https://ru.wikipedia.org/wiki/Compose (see, for example, questions here concerning xcompose - their https://ru.stackoverflow.com/search?q=xcompose )enough to add to the file ~/.XCompose line:<Cyrillic_IO>: "#" It's for the record. Yo.. similarly, if necessary, for construction:<Cyrillic_io>: "#" After that x-client you need this substitution, it's enough to reset (if you need all x-clients, it's easier to reset the x-session).
