Regarding klishd error - Can't create KTPd session (Alpine 3.23.2 os)

[Sivaram Naik]

Hi All,

I am new to Klish and working on to bring-up Klish CLI environment with client and Klishd daemon by sysrepo as DB (with help of klish-plugin-sysrepo plugin).

In spite of debugging for more than a day along with usage of M365 Copilot help,  not able to narrow down on issue or resolution where Copilot ended up suggesting for clean install after initial XML formats and .conf files correction though I might have missed to  explain all context to Copilot. 

Error:

 klishd-listen: Service process for client was forked: 2350
 klishd[2350]: Can't create KTPd session
 klishd[2350]: Close connection 6
 klishd-listen: Service process 2350 was terminated: 255

Environment/context:

  Linux OS: Alpine-3.23.2
  Klish : https://src.libcode.org/download/klish/klish-3.1

  libfaux 2.2.0
  klish‑plugin‑sysrepo 3.1.0

  libyang

NOTE: In same host and same sysrepo DB libraries, netopeer2 client and server setup works all for Netconf setup.

Checked similar errors on this group and followed below mentioned steps as well, however issue remain persists.

some config files corrected from Copilot.

Any light on this about what I am missing or steps to narrow down this issue is highly appreciated.

Thank you very much.

Hi

Probably it can't find XML configs.

It searchs for the schema in /etc/klish and ~/.klish dirs.

Your klish.conf and klishd.conf is totally wrong. The sourcecode tree contains examples for that files. Don't rely on Copilot etc. May be it works for well-known and widely used software but not for specific ones.
