I have just set up an FC 13 box for a small network application. At the core, the application is supposed to receive some data over a multicast on my local network. However, for some reason, I am not being able to receive any multicast data on this machine. Other machines, on the same network (connected on the same layer 2 switch) are receiving the multicast just fine. I have tried the following things:
1. ensure that I am joining the multicast on the correct interface: the machine has only one ethernet card. Also, after starting my application, I use netstat -g to check for group membership. The multicast subscription shows up fine.
2. ensure there is no error in the program: the program works fine on my person linux machine
3. ensure that the multicast is actually available: it is available on all other local machines. I also wrote my own small broadcaster. data from this broadcaster (running on the same box) is available to other machines but not to my own listener program.
4. no firewall/filtering settings on the layer2 switch
5. TTL setting on the broadcast: have tried changing it from 1 through 5 with no effect. Note that even if the broadcast is coming from the same machine, my machine does not pick it up while other machines on the network do so.
I suspect this has to do with some settings on the network card itself. Below is the output of /sbin/ifconfig on the card:
eth0 Link encap:Ethernet HWaddr 00:08:A1:67:BBA
inet addr:192.200.20.32 Bcast:192.200.20.255 Mask:255.255.255.0

When I try to compile some Java code on Ubuntu 10.10 (kernel 2.6+) using make and a Makefile.
I get an error indicating that the make utility cannot execute the java compile command (javac).
The error reads: /bin/bash: line 6: .: /usr/local/jdk1.5.0_18/bin/javac: cannot execute binary file
I am executing make as root. I have enabled permissions on all directories in the path /usr/local/jdk1.5.0_18/bin/javac and on javac itself.
I get this error whether using a jdk installed via ubuntu apt-get, or whether I install the jdk myself. And I get it using either Java 1.5 or 1.6
My machine has an 80386 processor. I notice the make utility is built for i686-pc-linux-gnu
However, I can manually compile using javac.
I can compile calling javac from within a bash script.
I can compile using the java compiler gcj from the command line: gcj --main=HelloWorld HelloWorld.java -o HelloWorld.exe
But I cannot compile java code from the makefile. Any reasons why I might be getting this error?

View 5 Replies View RelatedWe purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.
The first file is a "key" of second file. In the second file, the first word is the key of each line. Each key and sentence in second file ONLY have one line. The Second File have many lines with key, but not all the key is shown on file1, but file1's key MUST in the second file. How can I get the result like this: (Need to sort by the key from File1)

View 3 Replies View RelatedI'm confused about "hard link" feature. I've been learning from my UNIX Academy DVDs training that hard links to a file can be many and each of them is an effective filename for the associated data. So let assume that we have some very sensitive data in a file and we want it to be deleted and file has 20 links. I "delete" a file, but in fact I deleted only one "name" of it. My understanding from the training that data is still there until we delete the last associated hard link. But how can I find the names of all of them? If we have the names, they can be removed one by one. Or may be there's command that can trace all the "names" and remove them at once?

I'm trying to write a shell script which finds bits of data from a text file. at the moment i'm using grep and basically i need a function which will look through the text file and take the data out of it. the file has days, months, years etc and i want it so i can type feb 06 and it finds all of the data for feb 06.
the problem i have is i can type feb and all the information comes back for feb, but i can't get it more precise e.g. feb 2009 and it finds just feb 2009, it seems to ignore that latter half. I've tried experimenting with egrep and having two inputs but i can't seem to fuse them together, it only takes the first input.

basically the situation I'm in is someone mistakenly expanded an NAS without unmounting the drive on the server. This corrupted the superblock and its apparent that all the backups are no good. The drive in question was expanded from about 800gigs to 1.8TBs, its done via an NAS.
At this point I'm most concerned about getting the files off the drive, I can deal with resetting the file system but I really need those files. This happened within a week of me joining this group so I'm kind of doing damage control here, backups were not taken of this particular drive.

View 1 Replies View RelatedI manually rotated my catalina.out file, and now the file jumps to 30+Mb and when I try to view it, less tells me it might be a binary file. It sure appears to have binary data in it, about 30meg of it.
I did the rotate via a copy:
copy catalina.out to another file
cat /dev/null > catalina.out
I have tried using echo:
echo "" > catalina.out
...also with the same result.
This application isn't something I can just bounce when necessary. It kind of appears that the original file is still there - sort of. But is it not readable text anymore.
