Unable to ssh nodes with global IP
by Abu Attar Musharih
Dear List,
My internet connection is via mobile broadband. The ifconfig lists
the ppp0 with IP address,
ppp0 Link encap:Point-to-Point Protocol
inet addr:120.165.xx.xxx P-t-P:10.64.64.64 Mask:255.255.255.255

collisions:0 txqueuelen:3
RX bytes:3867747 (3.6 MiB) TX bytes:1020544 (996.6 KiB)
I tried to remote login (using ssh) to this IP address from another
machine but failed.
The following message appears,
ssh: connect to host 120.166.xx.xxx port 22: Connection timed out
Editing /etc/sysconfig/iptables and add --dport 22 -j Accept does not help.
Could any one please provide some suggestions?
Thanks in advance,
AA

usb serial console and systemd?
by Kevin Martin
I can't seem to get systemd to spawn a getty on a USB tty. Here's what I've done:
# ln -sf /lib/systemd/system/getty@.service /etc/systemd/system/getty.target.wants/getty(a)ttyUSB0.service
# systemctl daemon-reload
# systemctl start getty(a)ttyUSB0.service
When I look at the gettys that are running, all I see are:
root 1153 1 0 Oct22 tty6 00:00:00 /sbin/agetty tty6 38400
root 1154 1 0 Oct22 tty4 00:00:00 /sbin/agetty tty4 38400
root 1155 1 0 Oct22 tty5 00:00:00 /sbin/agetty tty5 38400
root 1156 1 0 Oct22 tty3 00:00:00 /sbin/agetty tty3 38400
root 1157 1 0 Oct22 tty2 00:00:00 /sbin/agetty tty2 38400
I *do* have a ttyUSB0:
[27151.541139] usb 1-1.2: pl2303 converter now attached to ttyUSB0
But can't seem to get a getty. What have I missed (sure was easier under inittab)? Oh, and where do you set the speed, vt, etc. for the getty under systemd?

more attempts to resolve NSF issues
by Gerhard Magnus
I can ping (and ssh) the server from the client.
When I restart nfs and nfslock on the server I get this in the
server /var/log/messages:
PuteF kernel: [25572.902466] NFSD: Using /var/lib/nfs/v4recovery as the
NFSv4 state recovery directory
PuteF kernel: [25572.902504] NFSD: starting 90-second grace period
PuteF rpc.mountd[8699]: Version 1.2.4 starting
But on the client, mount /home/magnusg/Music returns:
mount.nfs: access denied by server while mounting
192.168.1.14:/home/magnusg/Music
a couple more things
(1) on the client, showmount -e 192.168.1.14 (the server)
Export list for 192.168.1.14: (shows nothing)
But on the server, my /etc/exports file contains:
/home/magnusg/Music 192.168.1.12,192.168.1.13(rw,insecure,sync,nohide)
(2) also on the client, trying to mount with mount.nfs:
mount.nfs PuteF:/home/magnusg/Music /home/magnusg/Music -v
mount.nfs: timeout set for Sun Oct 23 17:25:32 2011
mount.nfs: trying text-based options
'vers=4,addr=192.168.1.14,clientaddr=192.168.1.13'
mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting
PuteF:/home/magnusg/Music
OK, my only contact with people who use Linux these days is on this
list, so I have no idea what the current "lore" is. Does anybody
actually use NFS anymore? If not, is there any alternative to NFS
besides using ssh?
-------------------------------
Restating the problem from yesterday:
On the server, running FC15 (192.168.1.14):
(1) My /etc/exports file looks like this:
/home/magnusg/Music 192.168.1.12,192.168.1.13(rw,insecure,sync,nohide)
(2) Using the system-config-nfs "General Options tab" I have "Allow
connections from port 1024 and higher" checked.
(3) I have services nfs and nfslock running on levels 3,4,5.
(4) In /etc/sysconfig/nfs I've set these ports:
RQUOTAD_PORT=4000
LOCKD_TCPPORT=4001
LOCKD_UDPPORT=4001
MOUNTD_PORT=4002
STATD_PORT=4003
(5) In the firewall I have these ports open:
NFSV4 2049 (tcp)
4000-4003 (tcp and udp)
111 (tcp and udp)
on the client, running FC13 (192.168.1.13):
(1) I added this to /etc/fstab:
192.168.1.14:/home/magnusg/Music /home/magnusg/Music nfs
rw,auto,hard,intr,bg 0 0
(2) Services netfs, nfslock and rpcbind are running on levels 3,4,5.
When I boot the client and get to the "Mounting NFS filesystems" section
I don't get error messages -- but I do see this:
mount.nfs: backgrounding 192.168.1.14:/home/magnusg/Music
: mount options
"hard,intr,bg,vers=4,addr=192.168.1.14,clientaddr=192.168.1.13
/home/magnusg/Music remains unmounted

Creating partitions
by Miguel Cardenas
Hello
I've installed Fedora 15 to try the distro, it was a bit difficult at first
(I have used Slackware for the last 8 years) but I'm beginning to become
familiar with Fedora usage, although I have a few doubts about the
partitions.
For years I used to create 2 primary partitions, SWAP and EXT3, but now I
found that Fedora requires a different layout with more partitions like
other *nix operating systems that distribute the space in more areas for
home, root, usr, etc.
I would like to keep simple my disk, and reading the Fedora installation
guide found that there are only 3 partitions required, SWAP, BOOT (ext3) and
ROOT / (ext3)... I still don't like the idea of an independent boot
partition but let's do it in the Fedora way... so, I want to know if this
layout may work for me... I want to ask before doing it to save hours of
installation just to try and see the results...
#1 PRIMARY type 0c (Win95 Fat32 LBA)
#2 EXTENDED
A - SWAP type 82
B - BOOT /boot type 83 (linux ext3)
C - ROOT / type 83 (linux ext3)
And one additional doubt... Fedora worked fine on this laptop but just
bought a new one, it comes with Windows7 preinstalled and want to keep the
original system backed up... Do you think it is safe to use Clonezilla for
any modern hard disk? My doubt is because I have a relatively old IDE disk
(80Gb) that after restoring a Clonezilla backup it does not boot anymore, I
guess it is due a possible different geometry interpretation by my installed
linux and the Clonezilla bootable linux, since the disk is ok and works
always perfect...
So, do you think it would be a good idea to backup Win7 on a SATA 500Gb
disk, no datafiles yet, just the operating system, I want to keep it for the
license...
And, after the backup, during the Fedora installation, it asks how to use
the hard disk, there is an option to shrink a used partition, but would it
work with Win7? As far as I know a NTFS partition can not be shrinked... is
it possible? can you comment something about this?
Thanks for your help!

Best FOSS alternative for skype?
by Marko Vojinovic
Ok, I just lost enthusiasm in further use of skype. Being closed source was
bad enough already, but I tolerated it due to its good-enough quality,
reliability and free-of-charge use for skype-to-skype calls. But now that
Microsoft is taking it over, I suddenly lost faith that these good features
will still be there from now on (not to mention Linux support).
Thus the question: is there a FOSS VoIP app that provides roughly the same
quality, reliability and free-as-in-beer service?
I do know that there are such VoIP apps, but I am not familiar with the
quality of service, availability and accessibility of each of those. I am
willing to migrate and start persuading my existing skype contacts (which are
scattered all over the globe) to migrate to a FOSS solution as well. But I
cannot do that if this alternative does not provide functionality that at
least matches that of skype. It has to be up to the task.
So which one is on the top of the list, in your opinion?
TIA, :-)

bluetooth problems F15
by Genes MailLists
F15 - I notice that on my laptop - sometimes - not always - bluetooth
stops working after a wake from sleep. It works most of the time, and
always works on a fresh reboot - but I usually sleep my laptop unless
I'm rebooting a new kernel.
Bluetooth works again by restarting:
systemctl restart bluetooth.service
I have standard F15 bluez.x86_64 version 4.87-7.fc15.
I note that there are newer versions (4.96) but not for F15 for some
reason.
The "bug" looks similar to this one
https://bugzilla.redhat.com/show_bug.cgi?id=716509
but this has had no activity since the original bz 5 months ago.
Anyone else aware of issues or resolutions?
Thanks ..

This sounds like its on the client machine - was hoping for logs from
the NFS server ..
