Ncat not working after upgrade from F17 -> F18

[Suvayu Ali]

Hi,

Has anyone else noticed ncat is not working after upgrading to F18?  I
am presuming it is because of some firewall issue, but I don't know how
to debug this.

This is a typical output:

$ nc -vvv www.google.com
Ncat: Version 6.01 ( http://nmap.org/ncat )
NSOCK (0.0030s) TCP connection requested to 173.194.32.114:31337 (IOD #1) EID 8
NSOCK (10.0130s) Callback: CONNECT TIMEOUT for EID 8 [173.194.32.114:31337]
Ncat: Connection timed out.

My usecase is to check if the Gmail imap servers are up before I sync my
email.  So a test like the following command gets stuck.

$  nc -vvv imap.gmail.com 993
Ncat: Version 6.01 ( http://nmap.org/ncat )
NSOCK (0.0030s) TCP connection requested to 173.194.70.108:993 (IOD #1) EID 8
NSOCK (0.0210s) Callback: CONNECT SUCCESS for EID 8 [173.194.70.108:993]
Ncat: Connected to 173.194.70.108:993.
NSOCK (0.0210s) Read request from IOD #1 [173.194.70.108:993] (timeout: -1ms) EID 18
NSOCK (0.0210s) Read request for 0 bytes from IOD #2 (peer unspecified) EID 26

Can someone help?

Thanks,


PS: I do not know if this is relevant, the new F18 kernel does not work
    for me so I am booting with the last F17 kernel 3.6.11-1.fc17.x86_64
