TCP 流量无法从虚拟 PC 上托管 Solaris 10 的 Windows 上的来宾路由到主机
我启动计算机并立即向 VPC 来宾操作系统 (Solaris 10) 发出 ping 命令。我使用 ping -t 10.3.6.63 (windows) 命令,以便 ping 在 Windows 计算机上继续。
这就是我收到的“来自 10.3.6.63 的回复:目标主机无法访问”。
我登录到 Solaris 桌面,发现我的域名未解析,现在处于“未知”状态。我从来宾计算机 ping 我的主机,并立即在主机上成功执行 ping 操作。如果我继续让 ping 继续,连接将保持稳定,并且我可以从主机连接到来宾计算机上的某些服务。
如果我禁用 ping 服务,连接最终将终止。例如,我的 Oracle 客户端会说连接被拒绝。
我重新发出 ping 命令,注意到我再次收到“Reply from 10.3.6.63: Destination host unreachable”。
这次我无法从来宾操作系统执行 ping 操作。因此,我运行 arp -d uspqlnb339 (主机 PC 的域名),然后从来宾操作系统重新发出 ping 命令;它成功了并且 ping 开始工作。
是什么导致该网络路径被破坏?
我在来宾帐户上运行 snoop,确实看到为我的主机提供服务的 DNS 服务器出现了很多故障。例如
“DNS R Error: 2(Server Fail) unkown -> uspqlsv131 DNS C _
nfsv4idmapdomain Internet TXT ?”
也许这是一个 DNS 问题。有什么方法可以在 Solaris 10 上关闭此功能吗?
I boot the machine and immediately issue a ping command to the VPC guest OS (Solaris 10). I use the ping -t 10.3.6.63 (windows) command so that the ping continues on the windows machine.
This is what I get "Reply from 10.3.6.63: Destination host unreachable."
I log in to the solaris desktop and realize that my domain name was not resolved it is now at "unknown." I ping my host machine from the guest machine and immediately I get the pings to succeed on the host machine. If I continue to let the ping continue the connection remains stable and I can connect to some services on the guest machine from the host machine.
If I disable the ping service the connection will eventually die. My Oracle client will say connection refused for example.
I re issue the ping command notice that I get "Reply from 10.3.6.63: Destination host unreachable" again.
This time I cannot ping from the guest OS. So I run an arp -d uspqlnb339 (domain name of host PC) and then re-issue the ping command from the guest OS; it succeeds and the pings start working.
What is causing this network path from being disrupted?
I run snoop on the guest account and I do see a lot of failure from the DNS server serving my host machine. For example
"DNS R Error: 2(Server Fail) unkown -> uspqlsv131 DNS C _
nfsv4idmapdomain Internet TXT ?"
Perhaps this is a DNS issue. Is there any way to turn this off on Solaris 10?
