From any other PC doing SSH to my Ubuntu 11.10,is failing.



My network setup:



Telenet ISP (Belgium) > Fiber cable <enter image description here > RJ45 cable straight > to Ubuntu PC



Even the SSH is running:

Other PC: retrying over and over

Follow up:



-- checked cable

   -- using cable tester and other detectors 

   -- no problem found in cable 

   -- used random 10 cables



-- adapter is not broken 

   -- checked it using circuit tester by opening the system 

      (card is new so its not network adapter card problem)

   -- leds are OK showing



-- used LiveCD and did same ping test was having same problem



-- disabled ipv6 100% to make sure its not the cause



-- disabled iptables 100% so its also not the issue



-- some more info

Step 1: BUG for network card driver r8169



Step 2: get the latest build version

Step 3: build / make



$ cd /var/tmp/driver

$ tar xvfj r8169.tar.bz2

$ make clean modules && make install



$ rmmod r8169

$ depmod

$ cp src/r8169.ko /lib/modules/3.xxxx/kernel/drivers/net/r8169.ko



$ modprobe r8169

$ update-initramfs -u

$ init 6


Voila!!

All was wrong only this fixed finally: (the default driver of Ubuntu 11.10 which shifts are not correct was causing this)



Step 1: get it



http://152.104.125.41/search/default.aspx?keyword=RTL8111



http://152.104.125.41/downloads/downloadsView.aspx?Langid=1&PNid=5&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false#RTL8111B/RTL8168B/RTL8111/RTL8168<br>RTL8111C/RTL8111CP/RTL8111D(L)<br>RTL8168C/RTL8111DP/RTL8111E<br>RTL8168E/RTL8111F



Step 2: cat README



# tar vjxf r8168-8.aaa.bb.tar.bz2

# ./autorun.sh  (as root or with sudo)





Step 3: lsmod | grep r8168 



note that: not 8169 was conflicting.





Works perfect now.
