old nfs client, new nfs host, incorrect mount option?
by Tom Horsley
I've got a system running centos 7 hosting lots of filesystems
available for NFS mounting.
I've got a gazillion virtual machines that need to have their
fstab edited to mount these filesystems.
I've now discovered that mechanically editing the fstab doesn't
work. On most of the VMs, if I say something like this:
bob:/builder /bob/builder nfs rw,bg,hard,rsize=8192,wsize=8192 0 0
then everything "just works", but as I go back in time, when I get
to a machine running fedora 11, I get the highly informative
"incorrect mount option" message. With lots of experimentation,
I eventually found that I could change the type from "nfs" to "nfs4"
and the mount would work.
Is there a guide somewhere for which idioms to use for which version
of linux I want to mount in? Is there any way to automate adding
these fstab entries correctly? I thought the nfs server was supposed
to automatically fall back to old protocols if the client didn't know
something, am I missing some sort of configuration on the centos 7 host?

Postfix-Server behind a DSL-Router
by Peter Ulrich Kruppa
Hi everyone,
please do excuse my unspecific subject - I don't really know what my
problem is yet.
I set up a Postfix-Server on my Fedora 21 box, which is connected to
the internet via
some Netgear Router. My private LAN is 192.168.10.0/24 with the Fedora
box fixed on
192.168.10.1 . My Netgear thing has got a fixed IP and hostname, let's say for
mydomain.com .
Now I can
- send myself mails from my Fedora box
- send mails from my Fedora box to the outside p. ex. my googlemail account
but I can't receive mails from outside.
When I do a
# tcpdump -n -i any tcp port 25
on my Fedora I can see many messsages like
10:34:09.338691 IP 212.227.17.11.64945 > 192.168.10.1.smtp: Flags [S],
seq 3273717964, win 14600, options [mss 1418,sackOK,TS val 1273019143
ecr 0,nop,wscale 9], length 0
10:34:10.339378 IP 212.227.17.11.64945 > 192.168.10.1.smtp: Flags [S],

ecr 0,nop,wscale 9], length 0
[...]
Any good ideas, what else I can do to analyze my problem?
Thanks for your answers

Stuck Maximised
by Jonathan Allen
Dear Fedora List,
Going to maximise thunderbird on a graphic screen session, I accidentally
clicked on the box next door and it maximised to being absolutely full
screen, with no top bar and all the normal desktop stuff obscured. I can
still switch tasks using Alt-Tab, in which case the top bars and the
desktop (I'm using Xfce) reappear for the other task(s).
How can I get thnderbird back to have a normal task appearance?

FC 20 Latest kernel update breaks tap-to-click function of TK820 trackpad
by Paul Erickson
Updating FC20 today to kernel version 3.19.3-100.fc20.x86_64 breaks the
tap-to-click function on my Logitech TK820 keyboard/trackpad. Returning
to kernel version 3.18.9-100.fc20.x86_64 fixes the problem.
Any thoughts?

testing snapper f21 btrfs
by Neal Becker
I have a default btrfs install of f21.
sudo btrfs subvolume list /
ID 257 gen 32476 top level 5 path root
I copied /etc/snapper/config-templates/default to
/etc/snapper/config/default, and edited /etc/sysconfig/snapper to
SNAPPER_CONFIGS="default"
BTW: there is NO documentation about this installed with the rpm, I'm not
even sure I did this correctly.
snapper list-configs
Config | Subvolume
--------+----------
default | /
[nbecker@nbecker2 linearizer]$ sudo snapper -c default list
Type | # | Pre # | Date | User | Cleanup | Description | Userdata
-------+---+-------+------+------+---------+-------------+---------
single | 0 | | | root | | current |
So am I all set up to be able to use snapper to snapshot, rollback, etc?
I see rollback is supposed to be able to change the volume that is booted,
but I'm afraid to try it.

unbound - how will private zones work in f22?
by Neal Becker
I know the plan is to use unbound to provide a local dns server in f22.
I believe my situation is common. I have f21 on my laptop, which I take
between home and work.
At work we have local dns info that is not public. Right now, NM is working
fine. At work, NM sets up resolv.conf:
# Generated by NetworkManager
search all.my.local.domains more.of.my.local.domains ...
nameserver 10.x.x.x
When I'm at home, NM sets things up ala comcast dns.
So, moving to f22. How will all this work?
Will NM still setup 'search' as provided by dhcp?
And I'm guessing NM will set
nameserver 127.0.0.1?
And then how is unbound setup to forward certain domain requests to go to
the local server provided via dhcp?

Firefox version 37.0.1 crashes on redhat.com
by Jim Lewis
I hope this is not off topic for this group. I decided to let Firefox
upgrade (?) itself to the latest version, 37.0.1. Nothing seemed wrong at
first, but when I tried to go to redhat.com it crashed. I filled out the
dialog thing, restarted Firefox, and went there again. Crashed again. Has
anyone else seen this? I have Firefox version 35.0 on another machine and
it does not crash on that website.

dnf and "RPMDB altered outside of yum"
by R Mercado
Hello List,
I installed dnf on my desktop (Fedora 21) a few days ago and haven't
removed yum.
Today I run yum as I had forgotten about dnf and got the warning "RPMDB
altered outside of yum".
Is the use of dnf a valid explanation of the warning I got?
Is there advice as to whether to remove "yum" or alias yum to point to
dnf?
Thanks,
RM
