Public bug reported: ---Problem Description--- Novalink provides a tool called mkvterm. Mkvterm takes an lpar id argument and creates a vty-server device on device nodes /dev/hvcs*. HVCS is a device driver for the IBM Hypervisor Virtual Console Server (hvcs). Mkvterm then uses socat to connect.
Socat is not behaving as expected. When escape=0x1d is passed, you have to hit enter for socat to close (expected behavior is Ctrl-] closing the connection). In addition, Ctrl-C closes the connection. When using the up and down arrows, junk is printed. Password is also visible. The follow commit fixes the above issues, please add: https://repo.or.cz/socat.git/commit/5ebf36038f39 ---uname output--- Linux neop91.pok.stglabs.ibm.com 5.4.0-173-generic #191-Ubuntu SMP Fri Feb 2 13:54:35 UTC 2024 ppc64le ppc64le ppc64le GNU/Linux ---Steps to Reproduce--- Fixes to other issues required to reproduce. Mentioned in other bugs. Configure a vty-server and try to connect with socat: /usr/bin/socat STDIO,raw,echo=0,escape=0x1d /dev/hvcs[minor num] Add You will see that the password is visible. In addition, the up and down arrows do not work, junk is outputted. In addition, Ctrl-] does not close the vterm. Ctrl-C closes the vterm, and it should not. ** Affects: socat (Ubuntu) Importance: Undecided Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) Status: New ** Tags: architecture-ppc64le bugnameltc-205805 severity-high targetmilestone-inin2004 ** Tags added: architecture-ppc64le bugnameltc-205805 severity-high targetmilestone-inin2004 ** Changed in: ubuntu Assignee: (unassigned) => Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) ** Package changed: ubuntu => socat (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2056485 Title: Multiple issues found on Ubuntu 20.04 against socat To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/socat/+bug/2056485/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
