ssh shell/ftp access for PocketBook Pro readers - Page 9

SilverGreen93 · 02-23-2026, 05:04 AM

Not sure how to tell that, but in my authorized_keys2 on my PocketBook I have two keys:
- the old ssh-rsa key that was working before the OS upgrade
- the new ssh-ed25519 key that I generated at your suggestion above

In my Windows user .ssh home directory I have the corresponding:
- id_ed25519
- id_rsa

I don't know where nistp256 is coming from in the logs.

@orontee pointed out in another thread that the SDK for version 6.10 was recently released. Maybe a version of pbsshd can be built against that SDK and uploaded by someone (not me). You will probably want to wait for that because it is looking like you are right about this being a system software issue.

Can you provide a link to the 6.10 sdk? I might try to build it myself, there were some instructions in the readme file.

6.10 and 6.11 SDK is here: https://github.com/Sean-on-Git/PocketBook-SDK.

Thanks! I built OpenSSL 3.6.1 with success, but I cannot build OpenSSH because I cannot find libcrypt.a in either the SDK or the PB device. So how did you pass the OpenSSH configure script with LIBS="$SYSROOT/usr/lib/libcrypt.a" ?

I get:
clang-15: error: no such file or directory: '/localdata/sources/pb/SDK-B300-6.10/usr/arm-obreey-linux-gnueabi/sysroot/usr/lib/libcrypt.a

I didn't try to build with this SDK yet. You can get one from the older SDK for static linking.
