First of all its NFS3 for sure, if I put nfsvers=4 parameter and try to mount -a I get:
mount.nfs: mounting ubuntuserver:/media/huge failed, reason given by server: No such file or directory mount.nfs: mounting ubuntuserver:/media/externi-disk failed, reason given by server: No such file or directory It's not firewall. Mine server is on 192.168.0.1, and client is 192.168.0.2. Here is an ufw rule: sudo ufw status: ... To Action From -- ------ ---- Anywhere ALLOW 192.168.0.2 Next I did a zenmap port scan, from client to server, here you are: PORT STATE SERVICE VERSION 21/tcp open ftp vsftpd 2.2.2 22/tcp open ssh OpenSSH 5.3p1 Debian 3ubuntu7 (protocol 2.0) | ssh-hostkey: blabla (DSA) |_2048 blabla (RSA) 80/tcp open http Apache httpd 2.2.14 ((Ubuntu)) |_html-title: Site doesn't have a title (text/html). 111/tcp open rpcbind | rpcinfo: | 100000 2 111/udp rpcbind | 100003 2,3,4 2049/udp nfs | 100021 1,3,4 33800/udp nlockmgr | 100005 1,2,3 50000/udp mountd | 100024 1 50001/udp status | 100000 2 111/tcp rpcbind | 100003 2,3,4 2049/tcp nfs | 100021 1,3,4 38914/tcp nlockmgr | 100005 1,2,3 50000/tcp mountd |_100024 1 50001/tcp status 2049/tcp open rpcbind 3128/tcp open http-proxy Squid webproxy 3.0.STABLE19 | http-open-proxy: Potentially OPEN proxy. |_Methods supported: GET HEAD 3389/tcp open microsoft-rdp VirtualBox VM Remote Desktop Service 3390/tcp open microsoft-rdp VirtualBox VM Remote Desktop Service 8000/tcp open ssl/http TwistedWeb httpd 8.1.0 (Twisted 9.0.0) |_html-title: Sign in -- Sage 9091/tcp open http Transmission BitTorrent management httpd (unauthorized) |_html-title: Site doesn't have a title (text/html; charset=ISO-8859-1). | http-auth: HTTP Service requires authentication |_ Auth type: Basic, realm = Transmission 50000/tcp open rpcbind 50001/tcp open rpcbind As you can see everything is open, ports 50000 and 50001 on server are the ones for NFS. I've also added on server hosts.allow: ALL: 192.168.0.2, and on client ALL: 192.168.0.1 On every other version of ubuntu this worked fine, and I haven't been changing any configuration on server. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/891825 Title: NFS client doesn't mount or mounts slow on startup on 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/891825/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
