Funny Shell Output: [01;32mtestfile.txt[00m instead of testfile.txt

由 ℡╲_俬逩灬. 提交于 2019-11-28 06:28:02
问题 Question: I'm getting "funny" character output from commands I send when using a ChannelShell and I'm wondering how to get just the regular output you see in a PuTTY session. By "funny" I mean I should see this: testfile.txt And I'm seeing this: [01;32mtestfile.txt[00m This is similar to the problem in this question except the answer does not satisfy my need. The answer there is to call setPty(false) on the ChannelShell which removes the "pseudo-terminal" entirely, but I need to have the

JSch SCP file transfer using “exec” channel

由 笑着哭i 提交于 2019-11-28 06:26:56
问题 I'm very new to the SCP protocol and JSch. I have to transfer a file fro a remote device via SCP to Android. The server side developers refused to tell be anything about their device except for the file location, and the root account which can be used to access it with SCP. Here are the steps I tried. Confirm that using JSch, my Android client can establish connection with the server. [complete] Confirm that using JSch, and the ChannelExec object, I can send the ls command and read its output

JSch to add private key from a string

由 廉价感情. 提交于 2019-11-28 04:48:18
问题 I have the contents of the key pair file for SFTP as a string. I need to use JSch to add the contents, but addIdentity only accepts a file path. Is there anyway I can do this? I see that the KeyPair class has a method - KeyPair load(JSch jsch, byte[] bytes, byte[] bytes1) I'm not sure what this does. 回答1: There is an addIdentity overload that takes the key from a buffer: public class JSch { ... public void addIdentity(String name, byte[]prvkey, byte[]pubkey, byte[] passphrase) See also Java

问题 I'm using JSCH for file upload ever sftp. In it's current state each thread opens and closes connection when needed. If it possible to use connection pooling with JSCH in order to avoid overhead caused by large number of connection opening and closing? Here is a example of function called from inside of thread public static void file_upload(String filename) throws IOException { JSch jsch = new JSch(); Session session = null; try { session = jsch.getSession("user", "server_name", 22); session

How can I specify the path of a JAR in an ant buildfile?

由 非 Y 不嫁゛ 提交于 2019-11-28 03:26:39
问题 I am executing lot of scp and sshexec and other remote commands from an ant build script. These commands don't work if jsch.jar isn't in the ant lib directory. To make it work, I copied the JAR into the ant lib directory, but this is not a good solution, as anyone else wanting to run the script would have to do the same thing. To run the ant target from Teamcity, we will have to explicitly set the path of the lib file. Is there a way I can specify the path of the JAR in the ant build XML

问题 I hava a .sh script which glues many other scripts, called by jsch ChannelExec from a windows application. Channel channel = session.openChannel("exec"); ((ChannelExec) channel).setCommand("/foo/bar/foobar.sh"); channel.connect(); if I run the command like "nohup /foo/bar/foobar.sh >> /path/to/foo.log &", all the long term jobs(database operations, file processing etc.) seems to get lost. checking the log file, only find those echo stuffs(before and after a long term operation, calculate
