Bug ID: 435167
Summary: IPv6: file freezes on IPv4/IPv6 hydrid network due to
nonsensical address passed to ssh
Product: kdeconnect
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: albertv...@gmail.com
Reporter: thi...@kde.org
Target Milestone: ---
SUMMARY
On a network with both IPv4 and IPv6, KDE Connect does find my Android phone,
as shown by the system tray applet and the device itself (unlike bug 427310).
Most functions work. File browsing does not and causes Dolphin and Plasma to
freeze.
STEPS TO REPRODUCE
1. Connect both the computer and Android phone to a network with both IPv4 and
IPv6
2. Ensure that KDE connect connects
3. Attempt to browse files on the phone
OBSERVED RESULT
Dolphin and Plasma freeze for a time. After some time (a minute?), Dolphin
displays a message in red at the top like "The file or folder
/run/user/1000/xxxxxxxxx/primary does not exist" (it really doesn't).
EXPECTED RESULT
KDE Connect browses my files.
SOFTWARE/OS VERSIONS
openSUSE Tumbleweed
KDE Plasma Version: 5.21.3
KDE Frameworks Version: 5.80.0
Qt Version: 5.12.2
KDE Connect Version: 20.12.3
ADDITIONAL INFORMATION
When the freeze is active, ssh can be seen in ps to run with the following
arguments:
ssh -x -a -oClearAllForwardings=yes -oPort=1740 -F/dev/null
-oIdentityFile=/home/tjmaciei/.config/kdeconnect/privateKey.pem
-oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null
-oHostKeyAlgorithms=+ssh-dss -oServerAliveInterval=30
-oNumberOfPasswordPrompts=1 -2 kdeconnect@2601 -s sftp
That "2601" is nonsensical. It's causing ssh to attempt to connect to IP
0.0.10.41. That "2601" is the first part of my IPv6 network address (as a
Comcast subscriber, I'm given a network in the prefix 2601:1c0::/26).
