Jun 2, 2011I'm having an issue where a server in CA (1000/full) and in VA (100/full) have very lopsided data transfer.
CA -> VA with iperf shows ~20Mbps
VA -> CA with iperf shows ~93Mbps
If we change the CA server to 100/FULL, transfer speed is 93Mbps both ways.
Some tuning was done to TCP window scaling parameters, but it won't correct the issue, just improve the CA -> VA numbers to what is listed above. I will say, turning TCP window scaling OFF will lower the transfer speed both ways to < 20Mbps.
The only clue I have when looking at wireshark dumps is that the window scale going OUT would never go past 10240 (scale is 8, so 2^8 x 40bytes). In the opposite direction, the window size will go above 3MB (scaled).
It is not a bandwidth problem as iperf with UDP shows 93Mbps both ways. Local transfers (CA 1000/full to CA 100/full) show full speed both ways, so I feel it is strictly related to TCP window scaling.
RedHat 5 64-bit on both sides. Any ideas why it won't scale above 10240?

Mar 18, 2010I have a server with 4 NICs in it. for HA and speed I have bonded 3 of them together (eth0-eth2) in my wonderful unmanaged 10/100 switch. 192.168.1.3. eth3 is cross connected via the patch panel to another system so that file transfers can be a 1000/FULL. I have created a 172.1.1.0 network between the 2 hosts. Problem is that once i connect the cross over NIC thes rest of the network cant see the server. I am sure it is a routing problem and added ip route add 172.1.1.0/24 dev eth3 172.1.1.0/24 dev eth3 proto kernel scope link src 172.1.1.0 192.168.1.2/24 dev bond0 proto kernel scope link src 192.168.1.2 169.254.0.0/16 dev eth3 scope link metric 1005 169.254.0.0/16 dev bond0 scope link metric 1006 default via 192.168.1.2 dev bond0

Apr 3, 2011I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.

Networking :: Connection Destroy Time With Net Filter Connection Tracking?
May 13, 2011When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
View 3 Replies View RelatedNetworking :: Use The Laptop With The Wireless Connection To Share The Internet Connection?
Feb 4, 2010I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.

Networking :: Shows Connection But Not Connected / "connection Information" Shows A Varying Percentage Of Connection?
May 26, 2010I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work. I've now restarted several times, and each time I restart, the wireless works for about 1 minute, then stops working. If I try to disconnect and reconnect it will not reconnect (until I restart, that is).
iwconfig shows the correct ESSID and ifconfig shows an address, and "connection information" shows a varying percentage of connection.
Networking :: Test Thespeed Of The VPN Connection Or The RDC Connection?

Ubuntu Networking :: Internet Connection: 'Work Offline' - "No Network Connection"
Oct 31, 2010I have the "Work Offline" problem: when I boot up, the icon on the toolbar tells me I have "No network connection". This is not quite true, since I can access the first page of any website - only subsequent pages are inaccessible. I get a message saying that Firefox is offline. However, when I uncheck "Work Offline" in the File menu, it makes no difference to this behavior.
The problem is on my Ubuntu Dell desktop, which is connected to the internet with cable broadband via a D-Link router (wired connection). It has worked fine up till now. I use Ubuntu 10.04 and Firefox 3.6.11. I am writing this on my Ubuntu Dell laptop which is wired to the same router, so I assume the problem is not the router. I have tried various strategies suggested in threads on these forums, including editing about:config, changing "allow" to "deny" in some lines of /etc/dbus-1/system.d/NetworkManager.conf and changing from Automatic (DHCP) to Automatic (DHCP) Addresses only, but no luck so far. The contents of ifconfig are:
eth0
Link encap:Ethernet HWaddr 001:aa0:91:a7:51
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets: 0 errors: 0 dropped: 0 overruns: 0 carrier: 0
collisons: 0 txqueulen: 1000
RX bytes: 0 (0.0 B) TX bytes: 0 (0.0 B)
[Code]...
If I comment out "auto eth0" as well, it makes no difference. If I uncomment both lines ("auto eth0" and "iface eth0 inet dhcp") then I lose the internet connection altogether.

May 17, 2010I am trying to build cross-toolchain for arm. I dont want ready-to-use solution. I want my own . I want to build toolchain manually, but I cannot compile gcc. When I invoke "make" I get the following error:
Code:

Make fails...my arm-linux-gcc is actually can be built. When I do the following:
Code:
make all-gcc
make install
I get my arm-linux-gcc in ~/Progs/cross-compilers/result/arm-linux. So I can compile kernel , but I want user-space , so I do:
Code:
make all-target-libgcc
Make fails when it tries to build libgcc (AFAIK I need libgcc to build glibc). But why does it fails? I have header files like "stdio.h" on my gentoo box. Maybe compiler somehow wants files like "stdio.h" for my TARGET (arm-linux)? But AFAIK these are files are Standart C Library header files, and glibc did not even compiled yet, so I dont have these headers for my TARGET...
I found description of this error here:[URL](gcc part). But when I add additional flags -Dinhibit_libc -D__gthr_posix_h, then make fails when it tries to compile ../gcc-4.4.2/gcc/crtstuff.c with the same errors.
Programming :: Cross Between Strace And Gdb
Dec 6, 2010I want to run a program under ... something like strace, something like gdb. Let's call the something Fred. Every time I run a particular program under Fred, it detects when a system call is about to take place or a signal has occurred, and traps to Fred, which decides dynamically how to respond, whether the stimulus is a signal or an attempted open(), close(), read(), write(), socket(), connect(), listen(), select(), ioctl(), time(), or whatever. Although strace does this marvelously, what I'd like Fred to do is use code that I supply to doctor up what the subject program sees. In the case of write(), it should be able to modify what actually gets written. In other words, a hard shell environment around the program which completely mediates between the subject program and the outside world. I'll start with the source code for strace and gdb if I have to. But has this been done already?

View 1 Replies View RelatedDebian Programming :: Cross Compiling With Qt
Dec 11, 2014I am trying to cross-compile my Qt application for armhf on Jessie, so what I did was install qt5-default:armhf, but when I tried running qmake I found out that it contains also an armhf version of qmake so I was not able to run it.Then I installed the amd64 version to have at least a runnable version of qmake, but it was only to find out that qmake contains only hardcoded paths, so I could not use it for the armhf libraries, well I could but I had to run qmake (amd64 version) and afterwards open the makefile and change all paths from amd64 to armhf.
But as this is not so convenient I was wondering if there is a normal way to do this, I know you can compile the source yourself but I had quite a lot of problems with dependencies there. Is it possible with the standard repository binaries or should I just go back to compiling the source myself? Maybe I can compile only the building tools without building all the libraries I already got from the repository.
