[RSowndarya]

Hi, i'm using devel branch of libyang,sysrepo,libnetconf2 and netopeer2. while building netopeer2,observed the error as below:

Could suggest me a solution for this?

[michalvasko]

There is no error, unfortunately. Can you maybe run the script manually for it to print something?

[RSowndarya]

hi Michal,

As suggested i have added print and run the script manually. But it didn't get print.

[michalvasko]

Okay, that complicates it. What Linux are you on, what shell are you using?

[RSowndarya]

Hi michal,

Build issue got resolved now. I have tried ssh callhome with example_configuration provided with devel branch. After authentication, timeout occured and observed few errors too in server.

Could you please help on this.

What libssh version are you using?

[RSowndarya]

using libssh 0.9.5

[michalvasko]

Build issue got resolved now.

Actually, could you mention briefly what the problem was? Maybe there is something to improve.

As for the SSH error, it is quite strange so I am asking again, what platform are you on, are you cross-compiling? What crypto backend library is your libssh using? Ideally, it should be OpenSSL, there are some problems with grypt, for example.

[RSowndarya]

what platform are you on, are you cross-compiling?

Linux 5.13.0-30-generic . No we are not cross-compiling

Ideally, it should be OpenSSL, there are some problems with grypt, for example.

Yes, openssl only, its version is 3.0.0

[michalvasko]

Then I suggest you turn on debug messages and maybe see something relevant there, for server its -c SSH. However, this is a libssh issue so I will likely not be able to help and you should ask them.

[RSowndarya]

Hi Michal,

Thanks for the suggestion. I will check by enabling the debug messages.

What crypto backend library is your libssh using? Ideally, it should be OpenSSL, there are some problems with grypt, for example.

Any specific libssh version we need to use for devel branch ?

[michalvasko]

Not really, starting from 0.9.5 it should work, but we are always using (and testing with) recent versions, currently 0.10.5.

[RSowndarya]

Hi Michal,

We are facing issue frequently during netopeer2 build. Please find the error log as below:

**_-- Installing missing sysrepo modules... -- Generating a new RSA host key "genkey" if not already added... CMake Error at cmake_install.cmake:141 (message): scripts/merge_hostkey.sh failed: 127

Makefile:99: recipe for target 'install' failed make: * [install] Error 1_

Could you please share your comments on this ?

[michalvasko]

You said you fixed this previously but have not replied how exactly. I cannot comment anything as there is no error message.

[RSowndarya]

just rebuild done for the specific module at that time it got fixed. No other particular fixes we done.

[michalvasko]

What specific module? You had the exact same error before and you fixed it somehow.

[RSowndarya]

What specific module?

sysrepo and netopeer2

[michalvasko]

I do not understand but it does not matter, without more information I am not able to help.

Issue got fixed after copying libs to expected path.
