Are the codes for SSH or Telnet available as a DLL?
No. adding SSH or Telnet code on DLL would take quite a lot of rewriting. Also, PuTTY itself don’t have faith in DLLs (they make installation susceptible to errors). Though we can’t ignore the fact that a little cleanup won’t hurt anyone.
Is SSH-2 supported in PuTTY?
Yes. SSH-2 is supported in PuTTY since v0.5. RSA and DSA Public key authentication in SSH-2 is a new feature of v0.52.
Is local echo supported on PuTTY?
Yes. v0.52 has adequate support for local echo.
In v0.51 and earlier, if you locally type a line, and until you don’t hit Return, the line is not sent to the server. This means you can correct the line if there’s any mistake before the server sees it. This meant local echo and local line editing could not be separated from each other.
But now, from v0.52 and above, they are separate options and by default, PuTTY will automatically decide to enable them or not. This decision is based on the user’s selected protocols and hints from the side of the server. If the default selection is not what you desire, you can enable or disable these functions as you like. These selection options are in the terminal panel under the ‘Line discipline options’ section.
Can I store my settings in PuTTY so the same process does need not to be done every time?
Yes, session profiles with names can be saved separately with all of PuTTY’s settings in them. The default settings used for new sessions can also be changed.
Is full-screen mode supported in PuTTY?
Yes, as a new feature of v0.52, PuTTY supports a full-screen like a DOS box.
What is the Unix port for?
Unix port is for little purposes. The terminal is very useful to someone who prefers PuTTY’s terminal emulation to xterm. Unix Plink might not have as many features but is free of the complexity involved in OpenSSL which makes OpenSSH installation tedious. There’s a common practice where users generate numerous SSH keys on Unix and then copy all of them to PuTTY. Eventually in this process, Unix PuTTYgen allows automation of the conversion process.
Can PSCP or PSFTP perform file transfer in ASCII mode?
Unfortunately as of now, files cannot be transferred in ASCII mode.
This has always been a restriction in SCP and SFTP file transfer protocols that files could be transferred only in binary format/mode. But that changed with the current draft protocol spec which proposed a means to implement ASCII transfer in SFTP protocol. SCP still faces the issue. PSCP/PSFTP may implement this change anytime soon.
What are the ports in PuTTY?
The latest version of PuTTY tools runs on Windows, Mac and Unix systems.
As of v0.77, the supplied PuTTY executables run on all Microsoft OS from WindowsXP up to Window10; and we will surely see and update soon for Win11 support. PuTTY provides 32-bit and 64-bit Windows executable files.
