Programming :: Detect A Closed Tcp Client Connection When Client Is Only Receiving Data ?
Mar 9, 2011I am writing a TCP server in C, and the server listens to incoming client connections and accepts them. It then creates a thread to handle the client. The clients are expected to only receive data from my server and not send any data. So if I use a select() call with a recv(), I believe that the recv() will just block forever since there will not be any data coming from the client. If I use a non-blocking recv(), then this will just return a 0 which tells me nothing because the client is not expected to send any data. I am not sure if I have misunderstood some socket concepts, but I need a solution to detect when the client has disconnected so that I can close the socket and stop sending data to the client. As I understand it, simple ACKs etc are not captured by the recv(), and only data sent by the client will cause recv() to return a non-zero value, so I am not sure how to know when the client has disconnected.

View 3 Replies View RelatedProgramming :: Physical Versus Virtual Mac Address And Mac Address From NIC's Firmware?
Apr 6, 2011I need a small shell based program that prints the mac address of physical ethernet adapter from it's firmware. I need this utility for license generation and appliance activation. I have tried several example but none of them is flawless, The easiest method I have found is to parse the output of "ifconfig" command but it has also some drawbacks.
1. Firstly program should differentiate between physical and virtual adapters. Physical means installed on board(wired or wireless) or installed additionally. Virtual adapters are those created by VPN or created by virtualization apps such as VirtualBox/VMWare etc. I am not interested in virtual ones.
2. In case of more them one physical adapters(wired and wireless), it should print the mac address and description(name & vendor) of both/all adapters.
3. If media is disconnected then also it should be able to read the mac address and description(name, vendor) of card.
4. This one is bit complex. I know that 'ethtool' can show you the universal mac address but it's limited to use only 2 types of drivers and won't work in all cases.

OpenSUSE Network :: Dhcp Client Does Not Receive The Dns Server Address
May 18, 2010I have installed a working DNS server on my home network. I have an unique server, devoted to dns, gateway, storage which runs opensuse 11.0 (I known that it is rather old). Two new clients require DHCP. I have installed, using yast, a very simple DHCP server, according to the following config:
option domain-name "XXX.XXX";
option domain-name-servers 192.168.0.1;
option routers 192.168.0.1;
[code]...
(I have tried to add "ddns-update-style none", and to remove the ntp-servers option, since my server is not a time server, without success). Unfortunately, even if the client (a mac running OSX 10.4) receives a right IP and gateway address, it displays neither dns server address nor default domain name. The same mac, on my office network (not managed by me), receives everything.

Server :: Send Traffic Down WAN Link Depending On Client IP Address Range?
Apr 15, 2011I am running Debian Squeeze with the following basic services running:DNS
DHCP
Samba
Squid
The server is setup with three NICs: eth0 (WAN1), eth1 (WAN2), and eth2 (LAN).The server addresses clients with an IP range of 10.0.30.1 - 10.0.30.254. Some clients will be set with reservations so they fall into the 10.0.40.1 - 254 range.
What I want to do is have any outgoing external traffic coming from the first range (10.0.30.0) to use WAN link 1, and any outgoing external traffic coming from the second range (10.0.40.0) to use WAN link 2.
I have sort of got something working. I have created a bare minimum transparent squid3 setup on port 3128, and set the iptables as follows:
Code:
iptables -t nat -A PREROUTING -i eth2 -p tcp -m tcp --dport 80 -j DNAT --to-destination 10.0.0.1:3128
iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128
iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128
I can get internet access, however obviously it only goes through one WAN link. It also seems slower than it should be. I experimented with tcp_outgoing_address, but seemed to not be my friend.
Ubuntu Networking :: NFS Client Connection On Only One Machine
Dec 13, 2010I have a number of Ubuntu machines running. Our NAS is FreeNAS. I am typing this on an Ubuntu 10.04 desktop that is successfully connects to an NFS share on the FreeNAS box every day. In addition, we have 3 10.04 server machines that also stay connected to the share successfully, Yesterday, I installed a new 10.04 server machine using IP 192.168.0.11. Everything works except connecting to the NFS share. It always returns with: mount.nfs: mount to NFS server '192.168.0.13:/mnt/amrd0s2/public-NFS' failed: timed out, giving up
Here's what I have checked: I can ping 192.168.0.13 (obviously) The NFS export mask is set to 192.168.0.0/16. The other machines are all on the same subnet as this problem machine (192.168.0.*) nfs-common, nfs-client, and portmap are all installed and running correctly. portmap is running correctly showmount -e 192.168.0.13 give the proper response:
Export list for 192.168.0.13: /mnt/amrd0s2/public-NFS/ 192.168.0.0 iptables isn't even installed (these machines are segregated in a private network behind a hardware fire all) There is nothing related to NFS is any of the syslogs. dmesg has one entry: [6.025966] FS-Cache: Netfs 'nfs' registered for caching which is insignificant. how to at least debug the nfs-client short of downloading the source and actually stepping through the code.

Jan 13, 2010I've just set up NIS on my home network (probably not necessary on this scale, but I wanted to try it out). The server and the clients are all running Debian Lenny. I've got it up and running and have my NIS users on the server logging into graphical desktops on a client machine.My problem is this: The users cannot access a lot of services that are native to the client because they're not members of the right groups (for example, they have no sound because they're not members of the audio group). I figured it would be easy; just add users to groups with the usermod command but the response I get is that the user in question is not present in /etc/passwd. If I understand NIS correctly I'm not supposed to add my users to /etc/passwd on the client machines.

General :: Networking - Changing MAC Address In A Machine (fedora 8)
Jun 24, 2010I am doing a test on MAC learning and for that ,I need to change my MAC address of linux machine while the interface is UP. To be more clear, consider eth1 in a fedora core 8 machine. And while the interface is UP. I am running a script which changes the MAC address from 10:1:1:1:1:1 to 50:50:50:50:50:50 (i.e 50 times MAC address is changed) . When I try to change the MAC address when the interface it UP, it gives me the following error :
siocsifhwaddr : device or resource busy
I know the way of changing the MAC address by bringing down the interface but I need to know if this can be done while the interface is UP.
