Programming :: C/C++: Broadcast Receives No Answer - Can't Find Right Answer
May 18, 2010How can I set the outgoing port for the socket? In wireshark, my outgoing port is 1024, and i want to set it to 6800 (or a similar port) I see the outgoing broadcast-message in wireshark, but no answer. There are three ECU's in the LAN, which should answer. The following code is a mixture of C/C++ and jointed from different articles:
[code]...
In wireshark I can only see the outgoing message. But the "recvBuffer" (in the lower part of the code) contains the same content as the sendBuffer. Is it right, that I need a sender and further more a receiver? Or should I receive the broadcast-answer on the same socket on which I send the bc?
CentOS 5 Server :: Home DNS Server Refuses To Answer Requests

Server :: Getting Modem To Answer On The Correct Ring
Aug 2, 2010I am having issues getting the modem it the dial-in server I have set up to answer on the correct ring. I have the /etc/inittab set:
Code: S1:2345:respawn:/sbin/mgetty -n 7 -x 6 -D ttyS2 yet I have to play with 'init q' and minicom to get it to answer on ring 7. Then a reboot destroys the setting and I have to go through the whole hassle again and it goes back to answering on the first ring.
This is not acceptable. This dial-in server is only a very back door into my network. It is only turned on when needed. Most of the time it is not powered up. When it is turned on it is by a non-tech person with out the ability to jump through the hoops to get it to answer on the correct ring.
Ideally I want this modem to just listen to the line after it stops ringing to check for a data signal and if it does not find it just hang up. If it finds a data signal then establish a connection and all that. That way it does not interfere with answering machine on the line. Google has yielded very little info about setting up dial-in servers. Modems are not used very much any more.

OpenSUSE Install :: Authoritative Source On 11.3 Kernels?
Nov 20, 2010OpenSuSE 11.3
2.6.34.7-0.5-desktop i686
Installation used default options. Discovered that my "standard" Desktop kernel isn't likely PAE enabled... Have had various FF windows open for a long time even with no network connection which resulted in memory leaks (understandable). Eventually the machine slowed to a crawl with numerous FF processes running (each about 8% of CPU) and 4GB memory map (4GB physical RAM) exhausted but surprisingly the 2GB swap was totally untouched. Searching the Forums there are numerous anecdotal opinions that PAE should be or was enabled automatically at least for Desktop kernels. Viewing the OpenSuSE repository, there are kernel-pae packages for this kernel version which aren't installed.
So before I start installing packages willy-nilly, is there an authoritative published source that documents what is is in an OpenSuSE kernel package, and what combination of packages plus if necessary additional manual configurations to achieve desired goals? BTW - I'm somewhat surprised that today PAE is not automatically included in today's kernels considering how cheap hardware is... I don't know if PAE typically should be a noticeable performance hit on low resource machines(like netbooks) and would be necessary for anything configured with more than 4GB total (physical plus swap) memory.
General :: VPS Does Not Answer Any DNS Request?

May 6, 2011Im a bit stuck with a simple script that im practicing with... im trying to get my head around some simple scripting. Basically i want to write a script that will work as below: It will ask the user to enter their userid. If its correct it will say 'Correct' If its the wrong id (But the ID exists in /etc/passwd) then it will say 'incorrect' If its not a valid userid it will say 'doesnt exist'. What i have so far is:
[Code]...
# If the user enters their own userid they will get a comment saying 'correct' $LOGNAME) echo "Correct";;
# If they enter another users ID (That exists in the /etc/passwd), then they get a message to say 'incorrect userid used'. Im not sure what i need to do here to get it to check the /etc/passwd to see if the input exists in there.... im guessing some kind of simple 'if' statement to say ---- "if 'input' exists in /etc/passwd then echo "incorrect userid used"
# If its entered incorrectly and not a valid ID then they will get this comment. Again, im guessing this part would be similar to te above option..... *) echo "not a valid ID";;
Ive managed to work out how the basic Case staements work, but to add a conditional statement based on the input, i just cant figure out. I have tried looking on google, and found some help but it doesnt really explain how i check the input against the /etc/passwd.
Networking :: BIND - Remove "Authoritative Nameservers" In UDP Message?
Jan 28, 2011We have our Microsoft AD DNS servers replicating to our Sidewinder - which uses BIND for its DNS server. We ran into a situation where reverse lookup requests to the Sidewinder returned back a truncated UDP packet to the DNS client. When we added another DNS Microsoft Domain Controller, it added that name in the authoritative nameservers section of the UDP message which put it beyond the 512 byte limit. It was at about 500 bytes before we added the domain controller - then it moved to 529 which caused BIND to set the truncation flag bit in the UDP header causing the DNS client to come back in TCP mode to get the full message.
Microsoft DNS doesn't send back the "Authoritative nameservers" section in its UDP responses to reverse lookups - they probably learned that the hard way and took it out and only send back the Question and Answer section. Is there a way to modify BIND to not send the "Authoritative nameservers" section in its UDP responses and only the Question and Answer?

Ubuntu :: Can't Seem To Find Answer?
Aug 23, 2010I've been googling around and can't seem to find my answer. I've got an old ATI 9700 pro that I'm removing from my system. I'm replacing it with an Nvidia GeForce 6200. What do I need to do to switch these in Karmic? I tried switching the cards, but I only get a white screen with the pointer on the new card. I can't do anything else. I'm guessing I have to uninstall the open source ATI driver first. How do I do that?

The modem has been installed as dev/tty/USB0I did compile Gobi loader 0.7 and it did run make and make install without error. The gobi rules are correctly installed and I did copy the firmware in the respective directory. The problem is: did I copy the right firmware? Is there some other problem. How can I diagnose if the firmware is the correct one (I unpacked the windows ones on a windows machine and there are 6)?

Security :: Users Subverting Security On Purpose / Kerberos Only Answer?
May 12, 2010I have an environment with multiple projects that have a variety of government and commercial sponsors. We have been satisfied to this point with a netapp serving nfs/cifs and keeping a tight reign on nfs exports.Some of these projects have started asking us to provide access restricted sub-folders of the project space based on different groups that contain a user subset of the primary group.
We have a linux machine that serves as a version control front end to the netapp, mounting the project spaces via nfs. People are now mounting their project space via sshfs to this "front end" and sharing the root password of this sshfs client with everyone in their project, in turn creating a security hole to access the so called restricted sub-folders. I know all the obligatory responses referring to irresponsible user behavior but would like to see how others have addressed something like this where user behavior seems out of control.
