Mac OS X to Ubuntu SMB connection fails from 1 IP address only
Posted on 2011-02-27
I have a cloud based Ubuntu 10.10 server running smbd for a single shared directory. I am Linux n00b, but have successfully installed SMB and several other services.
I can connect perfectly to it from any location except my home IP address. argh. Using my Mac laptop from another Internet connection works fine. So I know it is not an issue with the laptop.
Connecting from any machine behind my public IP address fails.
Here is what does work from the machines that can't connect to the samba share :
• SSH into the server
• Ping server
• resolve host name
• ftps into server
There are no firewalls in place on either end. I can also connect to a SMB share I have running on a Mac server here in my office remotely so I know that my ISP is not blocking port 139 at all. I have also confirmed with the cloud server host that they are not performing any filtering.
There are no allow.hosts or deny.hosts entries.
I am at a total loss as to why just connections from my IP address on multiple computers would not work.
Is there some kind of max connections or max failed attempts in a configuration file that would cut me off?
