ssh 不适用于通过 TCP/IP 连接的网络

ssh 不适用于通过 TCP/IP 连接的网络

我有一台主机,连接到一个从机,IP:10.105.186.10

我 ping 该 IP:

jcl023es@debian:~$ ping 10.105.186.10
PING 10.105.186.10 (10.105.186.10) 56(84) bytes of data.
64 bytes from 10.105.186.10: icmp_seq=1 ttl=109 time=211 ms
64 bytes from 10.105.186.10: icmp_seq=2 ttl=109 time=210 ms

我做ssh:

jcl023es@debian:~$ ssh -p23 [email protected] -lroot
ssh: connect to host 10.105.186.10 port 23: No route to host

我的IP配置:

eth0      Link encap:Ethernet  HWaddr c8:9c:dc:b2:0b:47  
          inet addr:10.208.185.120  Bcast:10.208.185.255  Mask:255.255.254.0

我不明白路由表是如何工作的。我有这个:

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
default         10.208.185.252  0.0.0.0         UG        0 0          0 eth0
dhcp_sede_sur.l 10.208.185.252  255.255.255.255 UGH       0 0          0 eth0
10.105.186.0    *               255.255.255.0   U         0 0          0 eth0
10.208.184.0    *               255.255.254.0   U         0 0          0 eth0

所以有什么问题?为什么我不能 ssh 我的奴隶?我的是直接有线连接...

编辑:对我来说,接口是由其地址、掩码和网关定义的。大豆,我知道这 3 个(我的机器的),并且我知道从站的地址。似乎使我的接口与要连接的从属地址位于同一网络中还不够...“没有到主机的路由”消息是否与路由表有关?
