I get an Ubuntu 12.04.5 source (linux-source-3.13.0) and have a check on centos7, (for I don't known how to build and install kernel on ubuntu). I found the problem maybe fix by the following patch (Ubuntu 14.04 includes), "NFSv4: test SECINFO RPC_AUTH_GSS pseudoflavors for support", https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=66b0686049 the following two patch needs apply with the above, https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=8445cd3528b https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=57bbe3d7c11 thanks, Kinglong Mee On 3/14/2017 16:47, Houlinfei wrote: > hi Kinglong: > At client, > > # cat /proc/version > Linux version 3.13.0-32-generic (buildd@phianna) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #57~precise1-Ubuntu SMP Tue Jul 15 03:51:20 UTC 2014 > # cat /etc/issue > Ubuntu 12.04.5 LTS \n \l > > thanks, > houlinfei > > On 3/14/2017 13:41, Kinglong Mee wrote: >> On 3/14/2017 11:52, Houlinfei wrote: >>> hi Kinglong: >>> There has no firewall.
