To run Windows programs in Linux we use Wine. But how to open any file with exe program using Wine? For example we have 1.txt file. To run this file with notepad.exe use command:
wine "/home/user/notepad.exe" 1.txt
To associate some type of files with EXE program we can use shell script:
#!/bin/sh QUICKPARLOCATION="/home/user/Notepad.exe" PARAM=`winepath -w "$*" 2>/dev/null` wine "$QUICKPARLOCATION" "$PARAM" & exit 0
Put this file in /home/user/bin directory. Open file properties and in field “Open with” select Notepad.sh script:
Sometimes bad driver of hardware load one or all cores of CPU by 100%. Some hardware has no other versions of driver and we must use bad driver.
Solution is – disable and enable hardware in Hardware manager. To do this automatic use script:
set HARDWARE_ID="PCI\VEN_8086&DEV_4229&SUBSYS_11018086&REV_61" devcon disable %HARDWARE_ID% timeout /t 3 devcon enable %HARDWARE_ID%
I created two files: Stop.bat and Start.bat. First stop bad device when Windows is shutting down, and the second start hardware when windows is starting. This solution help’s me and CPU no longer load by 100%
The official WineHQ repository has a set of standard Wine packages that you can download and install on your system. Please follow these steps to do so:
Run the following command in the Terminal for adding i386 architecture before installing a 64-bit version of Wine:
sudo dpkg --add-architecture i386Next add the WineHQ signing key:
wget -qO- https://dl.winehq.org/wine-builds/Release.key | sudo apt-key add -
Then run this command to import the other key for the WineHQ Repository:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv F987672F
Now run the following command in order to add the relevant repository from the WineHQ:
sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'
Next update the Ubuntu package lists with the command:
sudo apt-get update
Now we can install latest stable version of Wine in Ubuntu or Linux Mint operating system:
sudo apt-get install --install-recommends winehq-stable
Sometimes if server is shutdown incorrect filesystem filesystem can be corrupted and loaded in “read only” mode.
To check file system status use command:
mount | grep /dev/sd
This command show filesystem status, if filesystem is read only – you will see “ro” status: /dev/sda2 on / type ext4 (ro,readonly,data=ordered)
To fix filesystem use command:
fsck /dev/sda2
This command will fix all errors on filesystem, To apply fix enter y on keybord. When fixing is complete reboot system and check filesystem again.
First install SNMP package:
sudo apt-get install snmp
To use SNMP in PHP install php-snmp extention:
sudo apt-get install -y php-snmp
Get SNMP information from router user command:
snmpwalk -v2c -Cc -c public 192.168.1.1 > out.txt
This command will get all SNMP information from router 192.168.1.1 and save it into file out.txt
Now let’s create file index.php and write code that will get all MAC addresses from BDCOM P3310 OLT. To get all MAC addresses use OID: iso.3.6.1.2.1.17.7.1.2.2.1.1. In PHP file create function SnmpGet:
function SnmpGet($host, $community, $object_id){
exec("snmpwalk -v2c -Cc -c ".$community." ".$host." ".$object_id, $snmpWalkReturn);
foreach($snmpWalkReturn as $value){
$oid = explode("=", $value);
$walk[trim($oid[0])] = trim($oid[1]);
}
return $walk;
}
Put SNMP result in variable $MacResult:
$MacResult = snmprealwalk2($hostname, $community, "iso.3.6.1.2.1.17.7.1.2.2.1.1");
In cycle foreach go through all elements and remove unnecessary data:
if(count($MacResult)){
foreach($MacResult as $Item => $Value)
{
$Oid = str_replace("iso.3.6.1.2.1.17.7.1.2.2.1.1.", "", $Item);
$Mac = str_replace("Hex-STRING: ", "", $Value);
if(!strpos($Mac, "STRING:")){
echo $Mac.' | '.$Oid;
}
}
}
Similarly get EPON interface id from OID: iso.3.6.1.2.1.17.7.1.2.2.1.2
