Cannot ping linux from Windows
I have set up a Linux machine in a windows network. The other day all was working well, I could ping from Linux any windows machine and from windows i could ping the Linux box. I setup samba via Webmin and was able to access the Linux shares via windows network neighbourhood.
However, today I have come in after a reboot only to find I can now no longer ping the Linux box from any Windows machine! I can ping out from the Linux machine so that side of things is OK.
If I try to access the Linux share via windows network neighbourhood, or try and cannot to Oracle (that is installed on the Linux box) I get a Timed Out error.
The Linux machine has been manually registered with the Windows DNS server, so it should resolve on teh network. I have done a idconfig from Linux and checked that the IP address specified is still in place and it is. Hostname shows that the host name is what it should be set to.
I am relatively new to the Linux world, so I am a little unsure how to proceed from here.
I have done some searches on line to try and get some info, but thus far no luck.
Can anyone suggest any ideas as to what I might try to fix this and make sure that it does not happen again.
