Http://www.byywee.com/page/M0/S755/755589.htmlThis article only describes how to apply the SFTP functionality implemented by Jsch.SFTP is the abbreviation for secure file Transfer protocol, the Enron document transfer peace talks. The transfer file can be thought of as an encryption method of Enron. SFTP is part of SSH and is an Enron format for transferring files to the office. SFTP is the application of encrypted transmission of authentication information and transmission of data, so the appli

Use JSCH in Java to connect to a remote server and execute linux commands Sometimes you may need to use code to control the execution of linux commands to implement some functions. JSCH can be used to solve such problems. The specific code is as follows: Public class CogradientImgFileManager {private static final Logger log = LoggerFactory. getLogger (CogradientImgFileManager. class); private static Channel

Background: During the installation script, some database operations are performed, which can be performed only by the DBA account. We use jsch to create an SSH channel and directly connect it to the target machine for execution. The effect is the same as opening the command line. The only special issue is the DBA password. The Oracle (Oracle for our database) script provides the function of inputting the password together,! I'm afraid of everything!

Sometimes you might want to use code to control the execution of Linux commands to implement certain functions. For this type of problem can be implemented using Jsch, the specific code is as follows: public class cogradientimgfilemanager{private static final Logger log = Loggerfactory.getlogger ( Cogradientimgfilemanager.class); private static channelexec channelexec; private static Session session = NULL; private static int timeout = 60000; T

Connecting to a remote database via Java JschSometimes our local code may not be able to connect to the database, because the database has added a whitelist, the IP server can connect to the database, but we can connect to the designated IP server, and then through the server to connect to the database, like many database visualization software. By using Jsch, we can also implement this functionality at the code level. Words do not say, directly open

A typical event was encountered in the recent project when Rhel's SELinux was set to disableUsing Java's Jsch library to invoke the SSH command will randomly return an empty string, the version I used is 0.1.49, and the latest version 0.1.51 is not tested.About jsch:http://www.jcraft.com/jsch/To this end, I specifically wrote a program test:Package Com.ibm.leo;import Com.ibm.gts.cms.common.guestssh.api.gues

Use the JSCH framework to access other nodes through the jump machine. Previously, I developed a code for Remotely accessing ssh for operations. Recently, a jump server is required to access the target service. After searching for a long time on the Internet and failing to find a good example, I read JSCH's API. But you can see it in the dark. Lenovo, does port forwarding map the target node ip: port to localhost: port, and then send a message through

exchange algorithms supported by OpenSSH and Jsch, one side is required to open the Exchange algorithm supported by the other.
