請問一下是在哪個環節發生問題 是openssh? env? bash?
ls /proc/self/fd/的 0 1 2 都存在,可是卻回應找不到
直接echo ok>/proc/self/fd/2也是同樣錯誤
我在舊的系統(2.4.20 SSH-1.99-OpenSSH_3.5p1)上是有輸出ok的
我對opensus10.0 及ubuntu 6.10和centos5.0上都是以root測試,也都是如此情況
opensus10.0 SSH-1.99-OpenSSH_4.2
centos5.0 SSH-1.99-OpenSSH_4.3
ubuntu 6.10 SSH-2.0-OpenSSH_4.6p1 Debian-5ubuntu0.1
還需要什麼方面的訊息判斷的請跟我說
ssh 10.254.254.2 'echo ok>/dev/stderr'
bash: /dev/stderr: No such device or address
root@MyBOX:~# ssh 10.254.254.2 'ls -ashl /proc/self/fd/'
