I have a netcomm nb16vw router which supports cable, adsl2+ and 3g internet. The router has 4 ports.
I would like to tcpdump all traffic that my router does when it makes a firmware update.
So I have taken a HP ProCurve 1800-8G switch and mirrored port 7 to port 8.
I have connected:
Internet connection in port 6
routers WAN port in port 7
Linux host running tcpdump in port 8
I suppose the router have a dhcp client on the WAN interface.
However I don't see any activity.
In our MD's house, we have fibre optic connection given by the ISP upto Distribution box inside the house where the fibre optic cable is connected to HUAWEI-ECHOLFIE HG865 terminal .From the RJ 45 port in that device , the ethernet cable goes to the DLINK 8 port switch.
I have a Cisco 2950 switch which has one of its ports connected to an Internet router provided by my ISP; I have no access to the router configuration, but I manage the switch.
If I leave all switch ports with their default setup (auto-negotiation of speed and duplex mode), this link always connects at 100 MBit/s, but in half-duplex mode.
I've tried replacing the cable, and also moving the link
Hi I'm quite new to networking and need some help with a home configuration...
I have an 8 port TP-Link SG3210 layer 2 802.1Q tag capable switch and a Cisco 1801 router.
I set up 3 Vlans on the switch and assign ports to each.
I want to make computers on each Vlan 'see' each other.
Can I set up a single port on the switch as a trunk port out to the Cisco 1801, and use the Cisco to route betwee
I have a 4 servers connected to a HP 2848 switch with uplink to a router (Linux or Cisco - doesn't matter). Total traffic is about 300Mbps with 60-70Kpps.
The problem is with a a port, connected to a router: per TCP connection speed is not more then 20Mbps.
I have the following scenario:
EX2200 Switch whit
ge-0/0/6 set as an access port on VLAN 80
ge-0/0/0 set as a trunk
port connected to a catalyst switch and various vlans allowed to pass includin vlan 80
On the Catalyst Switch.
port #3 set up as a trunk port that receives traffic from the EX switch.
port 42 is set up also as a trunk port that connects to a cisco router.
Port #46 is where t
I'm having a bit of trouble understanding which networking solution to use for my problem:
I have a home network which includes several computers behind a router either directly through the router or through switches.
The router I am using has DynDNS set up on it, I can VPN to my desktop via Hamachi, I can RDP via Windows 7 RDP, and I can do other sorts of fancy tricks.
The one last thing I wou
I have my router connected to the Internet. From the router, I have an ssh tunnel setup like this:
ssh -f tunnelserver.net -L 2000:proxy:8888 -N
This opens the port 2000 on localhost from my router. Now I want this port to be accessible from within my LAN, but it is closed. How can I open it?
I have GatewayPorts yes in /etc/ssh/sshd_config, if that matters.
