scplogs
Description of problem:
scp file from client to server failed with error "SCP client said 'lost connection'" ,but scp file from server to client successfully.
But the scp works well between rhel host and fedora.and works well between the old openssh version.
Version-Release number of selected component (if applicable):
Client host（A）:(the version of openssh is upgraded from 6.4 to 6.6.1)
openssh-server-6.6.1p1-3.el7.x86_64
openssh-6.6.1p1-3.el7.x86_64
libssh2-1.4.3-8.el7.x86_64
openssh-clients-6.6.1p1-3.el7.x86_64
Server host（B）:(install openssh while install the os)
openssh-server-6.6.1p1-3.el7.x86_64
openssh-6.6.1p1-3.el7.x86_64
openssh-clients-6.6.1p1-3.el7.x86_64
libssh2-1.4.3-8.el7.x86_64
Third host（C）:(install openssh while install the os with the old profile)
openssh-server-6.4p1-8.el7.x86_64
openssh-clients-6.4p1-8.el7.x86_64
libssh2-1.4.3-8.el7.x86_64
openssh-6.4p1-8.el7.x86_64
How reproducible:
Always
Steps to Reproduce:
1.Transfer the file from client host（A） to server host（B）,"lost connection"
2.Transfer the file from server（B） to client（A）,successfully.
3.Transfer the file from host A to host C and C to A ,successfully.
4.Transfer the file from C to B ,"lost connection".
from B to C,successfully.
Actual results:
Transfer the file from client host to server SCP client(6.6.1) said 'lost connection'
Transfer the file from client to serever(6.4 or 6.6.1 upgrade from 6.4) successfully.
Expected results:
Transfer the file from each other host successfully.
Additional info:
summary:
scp server version
6.4 <-->6.4 works well
6.6.1 <--> 6.6.1 don't work
6.4 -> 6.6.1 don't work
6.6.1->6.4 works well
so set keywords:Regression
I'm not able to reproduce your issue, it works for me as expected. Please provide a better reproducer and your configuration. Do you have anything special in ssh_config, sshd_config?
The problem is in /etc/profile.d/abrt-console-notification.sh:
[root@ibm-x3650m3-07 ~]# scp file localhost:file-2
root@localhost's password:
lost connection
[root@ibm-x3650m3-07 ~]# mv /etc/profile.d/abrt-console-notification.sh .
[root@ibm-x3650m3-07 ~]# scp file localhost:file-2
root@localhost's password:
file 100% 30 0.0KB/s 00:00
[root@ibm-x3650m3-07 ~]# cat abrt-console-notification.sh
# If shell is not connect to a terminal, exit immediately, because this script
# should print out ABRT's status and it is senseless to continue without
# terminal.
tty -s || exit 0
...
scp is run via shell on a remote side: /bin/bash -c "scp -v -t ."
and when a session is not interactive, bash is run without connected tty. call 'exit 0' is probably not the right solution in this case
