Hi all,
I'm trying to share some folders like /home and /var/mail with differents security flavors between some machines in a virtual network using VirtualBox. My virtual network is compunded of :
- my NFS server, also called nashome, IP address : 192.168.10.5. It's a Debian Squeeze Virtual Machine, using nfs-utils 1.2.2
- my email server, also called servicesext (external services), IP address : 10.1.2.10. It's a Debian Squeeze Virtual Machine, using nfs-utils 1.2.2
- my kerberos (MIT) server, also called serviceint (internal services), IP address : 192.168.10.4. It's a Debian Squeeze Virtual Machine
- my user computer, also called posteA, IP address : 192.168.10.50. It's an Ubuntu 10.10
NFS shared folders constraints are following :
- /home must be accessed using kerberos identification, I have to mount it on servicesext and posteA
- /var/mail is filled by exim4 so I can't use kerberos authentication, only sys flavor, I have to mount it on servicesext only
/export/home and /export/mail are bind mount :
mount --bind /var/mail/ /export/mail/
mount --bind /home /export/home/
All Squeeze machines have been updated at the same time and tests have reproduced using nfs-utils 1.2.2 with and without debian patches, and also with nfs-utils 1.2.3. Each time the same result.
1. Each time, when a share folder is set with sec=krb5 as security flavor, client is blocked and mount command never ends. For example (/etc/exports) :
/export -fsid=0,insecure,no_subtree_check 10.1.2.10(sec=sys:krb5) 192.168.10.50(sec=krb5)
/export/home -sec=krb5,rw,nohide,insecure,no_subtree_check 192.168.10.50 10.1.2.10
/export/mail -sec=sys,rw,nohide,insecure,no_subtree_check 10.1.2.10
- Using my servicesext (10.1.2.10) machine, I can mount nashome:/mail :
# umount /mnt/nfs4; mount -t nfs4 nashome:/mail /mnt/nfs4 -vvvv
- but when I try to mount nashome:/home, mount command never ends (see logs below)
# umount /mnt/nfs4; mount -t nfs4 -o sec=krb5 nashome:/home /mnt/nfs4 -vvvv
2. Instead of using sec=krb5, I will use old expression gss/krb5 : the following does not work
/export -fsid=0,insecure,no_subtree_check 10.1.2.10(sec=sys:krb5) 192.168.10.50(sec=krb5) gss/krb5
/export/home -sec=krb5,rw,nohide,insecure,no_subtree_check 192.168.10.50 10.1.2.10 gss/krb5
/export/mail -sec=sys,rw,nohide,insecure,no_subtree_check 10.1.2.10
3. And an amazing thing, if I remove all authentications except gss/krb5 I can mount nashome:/home (see logs below). Mounting on posteA works only if I remove it's IP address 192.168.10.50 from second line.
/export -fsid=0,insecure,no_subtree_check gss/krb5
/export/home -rw,nohide,insecure,no_subtree_check 192.168.10.50 gss/krb5
#/export/mail -sec=sys,rw,nohide,insecure,no_subtree_check 10.1.2.10
Following are logs files for mount and syslog on servicesext, nashome syslog, and servicesint Kerberos KDC logs for step 1 when mounting nashome:/home

- servicesint Kerberos KDC logs :
nothing new, credentials are in cache.
Did someone already encountered that kind of problem? I've tried a lot tutorials in internet but each time when I use a security flavor like sys with an other share with gss/krb5, mount command never ends when mounting gss/krb5 share. Following /etc/exports doesn't work unless I remove the first line. Once the first line removed, I can mount using krb5[i][p] security flavor.
/export *(rw,fsid=0,insecure,no_subtree_check)
/export gss/krb5(rw,fsid=0,insecure,no_subtree_check)
/export gss/krb5i(rw,fsid=0,insecure,no_subtree_check)
/export gss/krb5p(rw,fsid=0,insecure,no_subtree_check)
Thanks for any help, advices, best practices, tips...
