Just want to say Thanks!!

Just want to thank everyone for their help. I finally got the virtualization going. I know you guys that do this for a living may not feel this way, but in the eyes of this guy, this is AWESOME!! Been doing linux as a hobby since Slackware 1.0, then moving to RH 2.x. I have a little website but it's a hosted site. Back in the early days, I previously tried doing it from home. Upgraded to a 'business' class connection, static IP, etc. I remember one time driving from Charlotte, NC back to Lexington, SC at 8:00PM to reboot the server, and back to Charlotte. I now use my home server for testing new features. A php upgrade by my hosting company a few years about killed me. It took weeks to correct the deprecated functions. Hopefully now, I can stay a little ahead of the game. Now its set it an forget, unless there is a hardware issue, kernel update, version update, or me doing a reboot after an uninstall or something, I can spend my little free time on other things. Things have come a long ways because of people like you. Tip of the hat to you!!

Alternative GUI

Hey All, I'm considering moving from CentOS 6 to CentOS 7. I'm not interested in dealing with Gnome 3. I've heard good things about Mate, a fork of Gnome 2. it appears that Mate is available in the EPEL repository associated with CentOS 7. Have any of you tried Mate on CentOS 7? In your experienced opinion what would I be giving up by abandoning Gnome 3 and installing Mate instead? -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Virtualization Networking

Hello, I'm a little confused on which networking option I need to choose when setting up a VM. I set up two VMs this past weekend both with NAT. Both able to were access the internet. The first one, I created in my / file system but didn't really have the space so I deleted it. The second one, I created in /home/kvm, but deleted it as well when I couldn't access it FROM the internet. I had a full backup scheduled for that night and deleted it as well. I have one of those free domains/DNS from no-ip.com, centos7vm.ddns.net I plan to use as the host name. I want to be able to access this VM from the internet. So, how much in the network setup for the new installation do I need to do? Do I need to go with NAT or bridged? I did four installations last night and could get any of the access the internet with ym. Must have been dumb luck the first two times. I think it maybe something in iptables from one of the previous installs causing the problem. In ifconfig, I still have virbr0 and virbr1. Didn't have those before. Here's my iptables: # Generated by iptables-save v1.4.7 on Tue Sep 27 22:17:35 2016 *mangle :PREROUTING ACCEPT [29980:14598541] :INPUT ACCEPT [4740:1518258] :FORWARD ACCEPT [25240:13080283] :OUTPUT ACCEPT [6749:1743387] :POSTROUTING ACCEPT [30207:14647456] -A POSTROUTING -o virbr0 -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill -A POSTROUTING -o virbr1 -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill -A POSTROUTING -o virbr0 -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill -A POSTROUTING -o virbr1 -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill COMMIT # Completed on Tue Sep 27 22:17:35 2016 # Generated by iptables-save v1.4.7 on Tue Sep 27 22:17:35 2016 *nat :PREROUTING ACCEPT [1130:73984] :POSTROUTING ACCEPT [20:1245] :OUTPUT ACCEPT [245:19366] -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -p tcp -j MASQUERADE --to-ports 1024-65535 -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -p udp -j MASQUERADE --to-ports 1024-65535 -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -j MASQUERADE -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -p tcp -j MASQUERADE --to-ports 1024-65535 -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -p udp -j MASQUERADE --to-ports 1024-65535 -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -j MASQUERADE -A POSTROUTING -o eth1 -j MASQUERADE -A POSTROUTING -o br0 -j MASQUERADE -A POSTROUTING -o eth0 -j MASQUERADE COMMIT # Completed on Tue Sep 27 22:17:35 2016 # Generated by iptables-save v1.4.7 on Tue Sep 27 22:17:35 2016 *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :IP4BOGONS - [0:0] :f2b-default - [0:0] :f2b-dovecot-pop3imap - [0:0] -A INPUT -m set --match-set blacklistnet src -j DROP -A INPUT -m set --match-set blacklist src -j DROP -A INPUT -s 127.0.0.1/32 -j ACCEPT -A INPUT -m set --match-set block src -j DROP COMMIT # Completed on Tue Sep 27 22:17:35 2016 And my ifconfig: eth0 Link encap:Ethernet HWaddr 44:37:E6:53:1E:E2 inet addr:192.168.1.110 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::4637:e6ff:fe53:1ee2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:601486 errors:0 dropped:0 overruns:0 frame:0 TX packets:601818 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:412662650 (393.5 MiB) TX bytes:508284675 (484.7 MiB) Interrupt:20 Memory:fe500000-fe520000 eth1 Link encap:Ethernet HWaddr 00:1B:21:AF:6D:22 inet addr:192.168.0.111 Bcast:255.255.255.255 Mask:255.255.255.0 inet6 addr: fe80::21b:21ff:feaf:6d22/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:260 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:53372 (52.1 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:44216 errors:0 dropped:0 overruns:0 frame:0 TX packets:44216 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:26786210 (25.5 MiB) TX bytes:26786210 (25.5 MiB) virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:162 (162.0 b) virbr1 Link encap:Ethernet HWaddr 00:00:00:00:00:00 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:244 (244.0 b) Currently, the are no VMs installed or running.

mount.nfs: an incorrect mount option was specified
by Tim Dunphy 03 Oct '16

03 Oct '16

Hey guys, My NFS server has been working really well for a long time now. Both client and server run CentOS 7.2. However when I just had to remount one of my home directories on an NFS client, I'm now getting the error when I run mount -a mount.nfs: an incorrect mount option was specified This is the corresponding line I have in my fstab file on the client: nfs1.example.com:/var/nfs/home /home nfs rw 0 0 I get the same error if I try to run the mount command explicitly: mount -t nfs nfs1.example.com:/var/nfs/home /home mount.nfs: an incorrect mount option was specified This is the verbose output of that same command: mount -vvv -t nfs nfs1.example.com:/var/nfs/home /home mount.nfs: timeout set for Sun Oct 2 23:17:03 2016 mount.nfs: trying text-based options 'vers=4,addr=162.xx.xx.xx.xx,clientaddr=107.xxx.xx.xx' mount.nfs: mount(2): Invalid argument mount.nfs: an incorrect mount option was specified This is the entry I have in my /etc/exports file on the nfs server /var/nfs/home web2.jokefire.com(rw,sync,no_root_squash,no_all_squash) I get this same result if the firewall is up or down (for very microscopic slivers of time for testing purposes). With the firewall down (for testing again very quickly) I get this result from the showmount -e command: [root@web2:~] #showmount -e nfs1.example.com Export list for nfs1.example.com: /var/nfs/varnish varnish1.example.com /var/nfs/es es3.example.com,es2.example.com,logs.example.com /var/nfs/www web2.example.com,puppet.example.com,ops3.example.com, ops2.example.com,web1.example.com /var/nfs/home ansible.example.com,chef.example.com,logs3.example.com, logs2.example.com,logs1.example.com,ops.example.com,lb1.example.com, ldap1.example.com,web2.example.com,web1.lyricgem.com,nginx1.example.com, salt.example.com,puppet.example.com,nfs1.example.com,db4.example.com, db3.example.com,db2.example.com,db1.example.com,varnish2.example.com, varnish1.example.com,es3.example.com,es2.example.com,es1.example.com, repo.example.com,ops3.example.com,ops2.example.com,solr1.example.com, time1.example.com,mcollective.example.com,logs.example.com, hadoop04.example.com,hadoop03.example.com,hadoop02.example.com, hadoop01.example.com,monitor3.example.com,monitor2.example.com, monitor1.example.com,web1.example.com,activemq1.example.com With the firewall on the nfs server up (as it is all the time other than this short test), I get back this result: showmount -e nfs1.example.com clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host) This is a list of ports I have open on the NFS server: [root@nfs1:~] #firewall-cmd --list-all public (default, active) interfaces: eth0 sources: services: dhcpv6-client ssh ports: 2719/tcp 9102/tcp 52926/tcp 111/tcp 25/tcp 875/tcp 54302/tcp 46666/tcp 20048/tcp 2692/tcp 55982/tcp 2049/tcp 17123/tcp 42955/tcp masquerade: no forward-ports: icmp-blocks: rich rules: rule family="ipv4" source address="xx.xx.xx.x/32" port port="5666" protocol="tcp" accept So I have two problems I need to solve. 1) How do I open the firewall ports on the nfs server so that clients can contact it? I'm using firewalld on the nfs server. And 2) why am I getting an error saying that "an incorrect mount option was specified"?

Unbound, dns64 and CentOS 7
by Jason Bailey 03 Oct '16

Hi all, Is anyone using unbound to do dns64 on CentOS 7? A quick 'unbound -h' shows both 'validator' and 'iterator' modules, but no dns64. Was it just not included or is there a supplementary or alternative package I need to install? I had it working on CentOS 6 and don't recall any special setup, so when I realized the dns64 module was missing from unbound in CentOS 7, it kinda caught me off guard. jb
