Bu bir CentOS 5.9 makinesidir.
Kontrol ettiğim şeyler ...
- Bu dizine yazma iznim var.
- Kullanıcının duyarlı bir kabuğu vardır (/ bin / bash).
- Yolumdan çekilmeye çalıştım
~/.ssh/config
. - Bu makineye tamamen farklı işletim sistemlerine sahip diğer bilgisayarlardan scp'leme de başarısız olur.
- Disk dolu değil.
- Sshd yeniden başlatılıyor.
/ var / log / secure şunları içerir ...

Sunucuda başlayabilir , tekrar deneyebilir ve ilgili dosyadan alakalı görünen bir şey gönderebilir misiniz?
~/.bashrc
veya~/.profile
veya/etc/bash.bashrc
veya/etc/profile
STDOUT bir şey yazdırmak? bugzilla.redhat.com/show_bug.cgi?id=20527 . Sanırım Linux kullanıyor musunuz?
