Некоторое время я испытывал очень странное поведение SCP: всякий раз, когда я пытаюсь скопировать файл, вывод SCP содержит несколько подчеркиваний, и файл не копируется.
$ scp test.txt 192.168.0.2:~
job@192.168.0.2's password:
________________________________________
Когда я создаю SSH-соединение с помощью Midnight Commander и копирую файлы, он работает.
Некоторая информация о моей машине:
$ ssh -V
OpenSSH_5.8p1 Debian-1ubuntu3, OpenSSL 0.9.8o 01 Jun 2010
$ uname -a
Linux squatpc 2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:05:41 UTC 2011 i686 i686 i386 GNU/Linux
И я бегу Kubuntu 11.04.
Изменить: немного больше информации, как требуется в комментариях:
