6/21/2023 0 Comments Putty ssh config![]() ![]() Key files contain more data than a password, so they are harder to crack. SSH keys provide a convenient and secure way to log in without passwords. Alternatively, if you’re using OpenSSH from another system, you can use the -v flag and look for the “Server host key” line. If you are not sure whether to trust the address you were given, you can run ssh localhost (since SC1 uses OpenSSH) on the IBM i from QP2TERM or QSHELL and make sure the fingerprint matches. If the host’s fingerprint changes, SSH will warn you and refuse to connect, in case the server is an impostor. When you enter “yes” here, SSH will remember the host’s fingerprint and keep trusting it. SSH employs a “trust on first use” model. If the ACS “SSH Terminal” link does not work for you, you can open an SSH session manually using your chosen SSH client. This option will launch an SSH client with settings to connect to your IBM i server. Connecting to your IBM i systemĪn easy way to launch your SSH client is by clicking the “SSH Terminal” option from Access Client Solutions (ACS). Please find instructions under Further SSH server configuration (advanced) later in this article. Long user profiles: If you get an error such as “access denied,” and your user profile is more than 8 characters long, you will need to set PASE_USRGRP_LIMITED=N in the SSH config file. Run sshfrom any PASE-enabled terminal, such as QP2TERM, QSH, or another open SSH session. IBM i as SSH client (for example, copying from one IBM i to another): SC1 provides the OpenSSH client.If you don’t have OpenSSH or prefer not to use it, we recommend PuTTY. Windows: Since fall 2018, Windows 10 has included OpenSSH, available via the command prompt and the ssh command.macOS and Linux: OpenSSH is included – just open a terminal and type ssh.To start SSH automatically on IPL (system restart): CHGTCPSVR *SSHD AUTOSTART(*YES) Choosing an SSH client Starting SSH server: Type STRTCPSVR *SSHD Furthermore, WRKACTJOB should show jobs running function PGM-sshd Is SSH server running? NETSTAT *CNN will show activity on port 22 or whatever port you have configured. If you don’t have the SC1 LPP, you can get it from IBM. SC1 is usually installed as part of the operating system. Where to get SSH server: SSH, SFTP, and related programs are provided by the 5733-SC1 Licensed Program Product.
