Finally, open a text editor, paste the information from the clipboard into the editor program, and save it as a text file.

Once the problem occurs, please right-click inside the terminal window and choose Select All, then right-click again and choose Copy to transfer the information to the clipboard.With trace options enabled, you will notice debugging information displayed in the terminal window that isn't normally there by default when SecureCRT is attempting to establish a connection, and at certain times throughout the lifetime of the connection. If you open the File pull down menu again you should see a checkmark next to Trace Options, indicating that troubleshooting output is now enabled. First, open SecureCRT's main File pull-down menu and select Trace Options.It's often useful to see trace options output which provides debugging information that may help us better understand the problem that you're experiencing. Version 7.3.x is about 8 years old itself! So the 'Unknown file format' error would suggest that SecureCRT v7.3.7 is having a problem reading the RSA 2048 key files generated by ssh-keygen. Ssh-rsa AAAAB3NzaC1yc2EAA.(about 240 characters total).I2CaZhwiCbKHpFwd generated the id_rsa2048 file with the same user as whom I'm running SecureCRT, and I've confirmed that there are no weird ACLs that would stop me (running SecureCRT) from reading these/my files. Here's a redacted copy of the contents of id_rsa2048.pub: 'Identity.pub' and 'Identity') and must be Note that the public key and private key file must have the 'The private key file could not be found: On connecting the first time, I do get the proper Server host key recognize/change/accept dialog once and then on all connection attempts SecureCRT fails with: Ssh-keygen -b 2048 -t rsa -f id_rsa2048 -N Ĭonfigured a session in SecureCRT for PublicKey (only), selected to a Session keyfile, choosing the file 'id_rsa2048'.

That is, a decade ago VanDyke stated that SecureCRT can read SSH key files as generated by ssh-keygen, but I'm still getting 'Unknown file format'. I've seen this discussed many years in the past, but the advice received back then doesn't seem to work.
