cannot ssh or ping to wireless IP using Fedora 16
 
Hello,
I am trying to ssh from my Fedora 16 machine (KDE) to a computer (ubuntu) using a wireless IP address. Other computers are able to connect to the wireless machine, but it seems that the Fedora 16 is unable to connect to any wireless IP. I have both ssh-client and ssh-server installed.
BTW, ping also does not work from Fedora to wireless, but viceversa does work, both by ping and by ssh

Any idea why Fedora does not allow this?

Thanks!

Wireless doesn't matter. Does the Internet otherwise work?

Have you checked to make sure your interface on the Fedora box is setup correctly?
Are the two machines on different subnets?
Can you ping other machines and your gateway on the Fedora box?

Possible problems, in order of likelihood.
1. You're using the local subnet IP (could look like 192.168.*.* or a few other variations) and the other computers you're testing on are part of said subnet, but the F16 computer isn't.

Solution: Find the global IP, easiest done by googling "what's my ip" (Google has an IP thing)

2. Your firewall settings (router, computer, etc) only allow ssh to connect from the local subnet, or perhaps from specified MAC addresses.

Solution: Make sure ssh is port forwarded (router) and check your local firewall settings.

3. The computer you're connecting FROM has the problem with #2, rather than the computer you're connecting TO.

Solution: See #2.

1.first check the interface is connected properly

2. check the status of ssh using
service sshd status
3.if not running start it using
service sshd start


regards

Maybe you have firewall blocking the IP the Fedora machine is on so the Ubuntu one ignores it. What are you running on the other machines?

if ping works one way but not the other, then your connection is good. As mentionned above, check your firewall settings or any other security utility (ie ipsec ...).

If what's been said hasn't worked and your still having problems; check your access point for a setting called "Wireless Partitioning" it's used in situations like public wifi access and prevents wireless clients from talking to one another.
