Re: file system compatibility...
by JD
Just would like to chime in that you can use
the exfat filesystem which is supported by Windows and Linux.
The Exfat filesystem addresses some of the limitations of the vfat
filesystem.

Broadcasts and netmask
by CLOSE Dave
I have a Fedora 20 machine which is receiving UDP broadcast packets at
regular intervals on a high port. No program is presently listening
for these packets. If I run, "tcpdump -iany port 29531", I see each
of the packets arriving just as I expect.
But if I then use Ncat as a surrogate for an application, "nc -lup
29531", I sometimes don't see anything! Why not? (More details
below.) What obvious thing am I missing?
The machine has ten Ethernet ports, two Broadcom BCM5716 and eight
Intel 82576. The Broadcom ports are using the bnx2 driver, the Intel
ports use the igb driver.
Connecting the cable from the broadcast sender to any one of the ports,
I get the exactly same behavior. Without assigning the port an address,
tcpdump shows that the UDP broadcast packets are received but they are
not forwarded to an application. For example,
# ifup eth2
# ifconfig eth2
eth2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::92e2:baff:fe32:f8a8 prefixlen 64 scopeid 0x20<link>
ether 90:e2:ba:32:f8:a8 txqueuelen 1000 (Ethernet)
RX packets 3892 bytes 3552566 (3.3 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 652 bytes 230557 (225.1 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device memory 0xdc7c0000-dc7dffff
# tcpdump -ieth2 udp port 29531
tcpdump: WARNING: eth2: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth2, link-type EN10MB (Ethernet), capture size 65535 bytes
14:40:14.343946 IP 172.17.5.1.60142 > 255.255.255.255.29531: UDP,
length 1212
14:40:15.349595 IP 172.17.5.1.60142 > 255.255.255.255.29531: UDP,

14:40:16.360263 IP 172.17.5.1.60142 > 255.255.255.255.29531: UDP,
length 1212
# nc -i2 -lup 29531
Ncat: Idle timeout expired (2000 ms). QUITTING.
(The destination MAC address is FF:FF:FF:FF:FF:FF.)
When I assign the port an address, the result seems to depend on the
netmask I assign. For any netmask from 1 to 19, applications see the
broadcast. For netmasks from 20 through 32, they don't.
# ifconfig eth2 172.17.17.254/19
# nc -i2 -lup 29531
p%�{"00":24,"01":"13/10/15 00:34:36","04":0,"05":0,"06":3,"08":0,...
# ifconfig eth2 172.17.17.254/20
# nc -i2 -lup 29531
Ncat: Idle timeout expired (2000 ms). QUITTING.
For all netmasks, tcpdump still shows the packets being received.
(Obviously, tcpdump doesn't care about the port's address.) But I don't
understand why the drivers treat the broadcast differently based on
the netmask.
Of course, this behavior might not be unique to Fedora but that's the
environment I'm using. If this is known network behavior in general,
I'd sure appreciate some pointer to a reference.

mount permanently USB Hard Disk
by Angelo Moreschini
Hi,
I have problem to permantly install a USB memory on my computer.
1. ==============
the result of the command ls /dev/sdd* releve the USB Hard Disk in this way:
brw-rw----. 1 root disk 8, 48 Aug 1 14:44 /dev/sdd
brw-rw----. 1 root disk 8, 49 Aug 1 14:44 /dev/sdd1
brw-rw----. 1 root disk 8, 50 Aug 1 14:44 /dev/sdd2
brw-rw----. 1 root disk 8, 53 Aug 1 14:44 /dev/sdd5
2. ==============
the result of the command blkid is this:
.........
/dev/mapper/fedora_zorro-home: UUID="fbff88ad-4e0e-4de4-b370-df5992a8ecbe"
TYPE="ext4"
/dev/sdd1: LABEL="FEDORA" UUID="4458827258826312" TYPE="ntfs"
PARTUUID="39886053-01"
/dev/sdd5: LABEL="REPOSITORIES_subversion" UUID="F6808D39808D00FB"
TYPE="ntfs" PARTUUID="39886053-05"
/dev/sde1: UUID="6CF4-C3AA" TYPE="vfat" PARTUUID="da752cd9-01"
3. ==============
in this way I modified the file /ectc/fstab of my computerin this way :
#
# /etc/fstab
# Created by anaconda on Thu Jun 19 17:41:33 2014
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/fedora_zorro/root / ext4 defaults 1 1
UUID=c3a4694f-d933-4079-a0e8-863320229f64 /boot ext4 defaults
1 2
/dev/mapper/fedora_zorro-home /home ext4 defaults
1 2
/dev/mapper/fedora_zorro-swap swap swap defaults
0 0
#UUID=4458827258826312 /mnt/fedora ntfs default
0 2
#UUID=F68D8D39808D00FB /mnt/svn-repo ntfs default
0 2
==================
but ......
==================
but when I remove the comment from the last two lines of the content of the
file /etc/fstab then the computer start only in EMERGENCY MODE..
I should like appreciate to know what is wrong in the last two line that I
added to the file /ect/fstab..
and also to know I have to change them to have a correct working of the
computer
thank you
regards
Angelo

RoR, apache, passenger deployment problems
by Pete Stieber
I'm trying to deploy a sample ruby on rails application on Fedora 20.
The application runs locally using WEBrick. I have the
mod_passenger-4.0.18-4.fc20.x86_64 package and the associated ruby gems
installed. I'm very new to this so I'm sure I'll be asking some stupid
questions.
The first thing I notice is complaints in /var/log/httpd/error_log when
restarting apache with passenger setup. I've attached the relevant
error_log content. I googled, but couldn't find a clear answer.
Can someone help me out?
