✨ New Features Js A new Chilkat class has been added: Js is a minimal, standards-compliant JavaScript engine designed to embed JavaScript inside applications with very small footprint and fast startup. It executes JavaScript code inside an application without requiring a browser or large runtime. See About the Chilkat.Js JavaScript Engine Ai Provider — […]

Starting with the v10.0.0 release (end of September 2024), Chilkat moves to standard semantic versioning. Prior to this release, for various technical reasons, Chilkat was stuck with versions 9.5.0.xx, where only xx changed. For this first leap to semantic versioning, where the major version changes to 10 (from 9), there are no backward incompatible changes. […]
This is a good discussion about Understanding Remote SSH Shell Sessions.
Clarification on the acronyms “SFTP” and “FTPS” “SFTP” is the Secure File Transfer Protocol over SSH. It is a protocol unrelated to the FTP protocol. (It is actually a subsystem of SSH.) The Chilkat SSH / SFTP component is used for “SFTP”. SFTP is achieved by connecting to an SSH server at port 22. On […]
Commands that assume an interactive user at a shell prompt should not be passed to SendRequestExec. For example, the “more” command assumes there is a shell and that the user will press RETURN when another screenful of text is wanted. It would be more appropriate to use the Unix/Linux “cat” command w/ SendRequestExec. To run […]
When a command is passed to SendReqExec that produces no output, such as “echo 1 > test.txt”, then do not try to read the channel (such as by calling ChannelReadAndPoll) because no data will be forthcoming and the channel read will timeout (as expected). The correct sequence of method calls would be to: Call SendReqExec […]
The Solution: Issue solved. The problem was, that we stepped through the code and because of that too much time elapsed between connect and authentication. As we ran the program without breakpoints it worked. The Problem: The AuthenticatePw method failed and the LastErrorText contained this information: ChilkatLog: AuthenticatePw: DllDate: Jan 31 2010 UnlockPrefix: *** Username: […]
Here’s an example that demonstrates a rough start to creating a C# console SSH shell terminal (where the user can type commands and output from the remote command echos to the console: using System; using System.Collections.Generic; using System.Text; using System.IO; namespace SshTerminalConsole { class Program { static void Main(string[] args) { Chilkat.Ssh ssh = new […]

Question: I don’t see anything in the documentation or examples to indicate that “su” is supported w/ SSH? Is it possible to login to a user account and then “su” to root? Answer: “su” is a command just like any other Unix/Linux command. It is typed at the command prompt, it does something, and a […]
Question: I have an application using your code that does several SSH and SFTP command during processing. Can I just establish a connection, authenticate passwords and the other setup steps once and then use that connection throughout the program or do I need to perform these steps in every function? If I can do I […]
We’ve discovered that F-SECURE SSH/SFTP servers will disconnect during authentication if the SSH client identifier is “SSH-2.0-ChilkatSSH_2.0.0”. This may be overridden by setting the ClientIdentifier property to mimic PuTTY by using a string such as: “SSH-2.0-PuTTY_Local:_May_15_2009_16:25:24”
