无法启动 sshd 服务器实例

无法启动 sshd 服务器实例

我尝试在远程机器上启动我自己的 sshd 服务器实例(我不是 root 用户),但是失败了:

debug1: sshd version OpenSSH_4.3p2
debug1: read PEM private key done: type RSA
debug1: private host key: #0 type 1 RSA
debug1: setgroups() failed: Operation not permitted
debug1: rexec_argv[0]='/usr/sbin/sshd'
debug1: rexec_argv[1]='-d'
debug1: rexec_argv[2]='-f'
debug1: rexec_argv[3]='sshd_config'
debug1: rexec_argv[4]='-h'
debug1: rexec_argv[5]='ssh_host_rsa_key'
debug1: rexec_argv[6]='-p'
debug1: rexec_argv[7]='55000'
debug1: Bind to port 55000 on ::.
debug1: Bind to port 55000 on 0.0.0.0.
Bind to port 55000 on 0.0.0.0 failed: Address already in use.
Cannot bind any address.

我的 sshd_config 文件的一部分:

#   $OpenBSD: sshd_config,v 1.73 2005/12/06 22:38:28 reyk Exp $

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

 # The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
 # possible, but leave them commented.  Uncommented options change a
 # default value.

 Port 55000
 #Protocol 2,1
 Protocol 2
 #AddressFamily any
 #ListenAddress
 #ListenAddress ::

如果我取消注释监听器地址并使用任何 IP,显然是我自己的 IP(172.16.13.126),它会出现以下错误:

Bind to port 55000 on 172.16.13.126 failed: Cannot assign requested address.
Cannot bind any address.

答案1

Bind to port 55000 on 0.0.0.0 failed: Address already in use.

嘿,

正如 sshd 输出的倒数第二行所述,端口 55000 似乎已被另一个进程占用。您可以尝试在文件中配置另一个端口sshd_config。此处的回复还很好地解释了如何以非特权用户身份运行 sshd:

主题:如何以特定用户身份运行 sshd?

我还没有尝试过,但是乍一看描述似乎很合理。
