Re: file system compatibility...

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. See http://en.wikipedia.org/wiki/ExFAT

Broadcasts and netmask
by CLOSE Dave 01 Aug '14

01 Aug '14

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, length 1212 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. -- Dave Close

RoR, apache, passenger deployment problems
by Pete Stieber 01 Aug '14

01 Aug '14

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? Pete
