Routers / Switches :: Two PCs On Same Switch Unable To Ping Each Other
Jan 13, 2012
I have two windows 2008 machines on vmware. I assign 10.0.0.1/8 and 10.0.0.2/8 to them. Both connected to same virtual switch. Now should these two PCs ping each other? In my case they dont ping. What i get is Repy from <ip address>: Destination host unreachable.
I have an ESW 520 8-Port switch with a management ip address of 192.168.10.2 /24 After I reboot it, I can successfully ping it from a pc with an ip of 192.168.10.123 for about 50 consecutive times.After that, I get a "Destination host unreachable" (this icmp message is sent by my pinging pc (192.168.10.123).This obviously seems like a bug.Whenever I reboot it, it goes through the same sequence.
Recently we have configured new site where we are unable to ping global DNS from routers and switches.Checked in the firewall ICMP is allowed.The thing we did is we made Native vlan as vlan 10 (Data vlan ) instead of vlan1. Do this is the issue for not pinging.
I have a sg300-10 switch. i update the firmware with the last one. Things are complicated when i create 2 VLAN. ( really 1 VLAN cause the first is native ).So i have the first VLAN with the interface 192.168.1.254 ans the VLAN 2 wich IP is 192.168.2.254
I'm connected with my workstation ( ip : 192.168.1.2/24 with GW 192.168.1.254 ) and i try to ping a web server on VLAN 2 ( ip : 192.168.2.2/24 GW 192.168.2.254 )
Ping is OK ! But when i try to reach any ports of the webserver : Nothing.
i have a device connected to 2960 switch. It is an access port and i could ping the device from other switches , also from outside the lan. But i am not able to ping the device from 2960 switch alone. I suspected and checked the arp table and it was showing as incomplete. I created the manual arp entry and tried pinging but no luck.
My new employer has asked me to determine any issues that could be causing performance issues our LAN. The network has two subnets and one of the first things that I noticed is that I cannot ping computers on subnet A from subnet B. I've looked into this and found a few things.-I CANNOT traceroute to computers on subnet B from subnet A-I CAN NMAP to computers on subnet B from subnet A-Computers on subnet A CAN ping other computers on subnet A and computers on subnet B CAN ping other computers on subnet B-Computers on subnet A CAN ping and access servers on subnet BI am relatively new to networking and not exactly sure where to start investigating this problem.
every time i try to acces my linksys router my IE just auto adds http:// and opens google search results. I cannot make IE not auto add that freaking http thing, on the old win XP i could type in 192.168.1.1 and it just went straight to my router login. Do i disable this IE auto http crap? i simply cannot acces my router anymore??i can ping the router, even using Cisco network magic pro I tried to reset router checked my internet settings everything works fine, this pc has a dhcp auto configuration etc.
I have created an IPSEC VPN tunnel using a Cisco ASA5520 (corporate) to a Cisco SRP541W (remote). The corporate subnet is 10.1.0.0/16, and the remote subnet is 192.168.1.0/24. From the remote subnet, I can ping anything on the 10.1.0.0 corporate network, but I cannot ping from the corporate network to the remote subnet. At first I thought this was something obvious, perhaps an incorrect acl or something easy on the corporate firewall. However, we have several other vpn tunnels established, all set up the same, and they work just fine. After looking at it a bit more closely, if I ping the remote subnet I see the hit counter increment by one each time, which leads me to believe that traffic is in fact being routed properly.Now I'm thinking that something in the remote SRP541W that is not allowing icmp traffic, but I can't find it anywhere. To be honest I have never used this type of firewall before, they have all been Cisco PIX501/506e and ASA5500 models.
Cisco SG200-26 (not PoE model). After a power failure, at restart the switch seems unable to reboot. The power led starts blinking in green, after some seconds the connected ports start blinking as well, but the the switch reboots automatically after few more seconds.I tried to disconnect lan cables, power cord, and reset to factory by pressing and holding down the proper button for 30s and more, but no success.In the small amount of time the switch's ports seem to be powered up, clients don't receive packets, don't ping each other or the switch manage address.
......................Computer 3 Router 1 points to a VPNRouter 2 access to the internetComputer 3 needs to access router 1 (VPN). Both Computer 2 and 3 are in a different room than computer 1, and router 1. Computer 2 is networked via cat5e to router 2.Is is possible to have Computer 2 and 3 share the cat5e, yet access different routers?
I have an RV042 using Quick VPN to connect to a remote network. I have port 1723 forwarded to a static IP address on a Windows 7 Pro 64 bit PC. I can establish the VPN and ping a printer but not the Win 7 PC. I can not acccess any shares on the pc via the IP address. It has Norton Antivirus and Windows Firewall. This remote PC replaced a Windows xp PC that allowed access to the shares. I have tried access with a Windows XP Pro and Windows Vista Home Premium PC. Neither have worked.
I can telnet to switch from checkpoint firewall access port and from switch directly. I can ping/traceroute successfully to the switch. Access-lists 14 & 15 are allowing the traffic I want. The router on the other side of the FW has 2 static routes and a default static route set up.
Here is some of the config from my switch:service tcp-keepalives-in
service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone
aaa authentication login default local enable line none[code].....
Not sure of checkpoint firewall config....I have run wireshark when trying to telnet and I get no syn-ack back from remote switch. Just 3 consecutive syn attempts.I have some switches I can connect to and they go right through the 3 way TCP handshake and I cannot find any differences in the configs between the successful connections and the unsuccessful connections.
I am unable to connect vivotek ip7137 camera with d link or netgear router I tried all my best made the connection with eithrnet cable , reset both machine set static ip of pc but nothing is happening?
I have an Iball Baton Router. I am not able to connect to it from my PC. However, I am able to connect to the router from my Laptop.I have tried isconnecting and renewing the ip. Can see that ip (192.168.1.102) is issued to my PC and can ping to the same. But, do not get any reply when I ping to the gateway (192.168.1.1 - ip for the router). My OS is Windows 7 64 bit.Let me know if you need any more information
From My Router that connects to Cable modem i am unable to ping website 126.96.36.199I am able to ping all other websites fines.Same website i can ping from my pc and all other switches fine.Router has only 1 ACL thats for NAT.
Running EIGRP on network. Hub router connects to remote router via EIGRP and then I have 2 static routes getting traffic to the switch behind the checkpoint firewall(Edge-1 UTM). Some switches I can access while others I cannot.
would like to know how a bandwidth gets distributed in switches.for example consider a scenariowhere i have a coreswitch A and coreswitch B connected between each other througha a 1Giga Fiber, now each of my core switche are connected to two edge switches through fiber links. all edge switches have giga ports. now if i connect a pc with giga link in th edge switch of coreswitch A and tansfer a file to a PC connnected to the edge switch in network B.. how much bandwidth would i get?how does the switch allocate bandwidth?
I have a qsee dvr that is hooked up to a switch that is connected to a wirless router/modemI have forwarded the correct ports that I need to according to qsee, ports 80, 9000 and 100I can access the dvr from any computer on the network via its local ip address, but when I try to access it via a computer off of the network via the real world ip address of the network, I cannot access it. I can ping the real world ip address of the network and it is successful.
I try to login to my router http://192.168.1.1/ I try and put in the user name and password that I think it is. Is it the user name and password you set up or one that's already there and if so where can I find it??
I have just upgraded my AIM and Skype messengers and now it won't let me sign in. I did before with my old versions. It is saying that my internet connection is bad which it is not. I have looked up ports in my Yahoo messengers, Control Panel and Bit Torrent still nothing.
