Current statusThe default user name in OpenWrt is root, but the default is no password, so SSH does not open by default, but Telnet is used without password, when the root password is set, SSH is turned on, Telnet is closed. And the convenience of SSH is greater than telnet,telnet in the production and testing of the case to be used, so there is no way to let the two coexist. Step OneModify the Telnet self-boot script to remove password and SSH-relat

The Linux Server oraclejdk and openjdk coexist and configure the JavaEE development environment, oraclejdkjavaee Due to my academic needs, I need to build a JavaEE development environment in linux and work with windows students for development. JDK Since fedora uses openjdk by default, some problems may occur when it is removed.

The simplest way for NT to coexist with Linux is to install lilo in the boot area of the Linux primary partition when installing lilo in Linux. Then, after the boot disk of win98 is restarted, run fdisk to set the Linux primary partition to active. In this way, you can first select lilo when the system is started. If you do not select Linux, then, enter the nt loader. But sometimes you need to use nt loader to guide Linux for convenience. The followin

(Reprinted) the coexistence of php4 and Php5 has recently used a new PHP5, but does not want to affect the original PHP4. Therefore, we have found many ways to coexist, but they are not ideal. finally I found a good article about coexistence using APACHE and using different ports, which is very convenient. Download the PHP 4 for Windows Zip binary package, decompress it to any Directory (I decompress it to E: php), and rename php. ini-dist in it to
