Routers / Switches :: Still Not Able To Telnet / SSH To Switch?
Mar 14, 2011
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.
We have recently purchased SG 300-52Port Cisco Switch to support our Network but they constantly having some bizarre issues or I assume bugs, i.e. we cannot Telnet nor SSH to the switch now, whereas we were able to SSH before, we have set them up for Remote Log Services to get some syslogs and reports but no report have been generated nor logs,
I have done some testing through Wireshark and there are absolutely no reports / logs.We have some real issues with this switch and it’s hard to believe that this is a Cisco Product,
SG 300-52 Port Gigabit Managed Switch Firmware Version (Active Image ) : 126.96.36.199 Firmware Version (Non-active ) : 188.8.131.52 Boot Version : 184.108.40.206
......................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 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.
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 have more than 20 SF 300-24P 10/100 Managed Switch switches deployed and running in my office network. All these switches have web configuration utility enabled. We would like to enable telnet too. But for this I know I have to visit site to site, connect the switch manually with a laptop and enable telnet option. I am looking for how can I enable telnet in these switches using web-based switch configuration utility.
I have a Modem/Router combo and am trying to plug an 8 port switch directly into it and then have wireless AP's and other hardwired devices plugged into the switch. Normally, when I plug a switch into a router it requires no set up. This one on the other hand, will not work.
ISP Cable in Smart box. 4 cat 5 cables from various rooms in house to feed cable ready TV's and one from my computer room. Can I connect all cat 5's to switch that is connected to cable modem located in Smart box and connect Wireless Router to cat 5 in the computer room and expect router to work properly?
I have a dell powerconnect 2848 switch and setting up a vlan 3 an make port 1 mngt, port 48 uplink to layer 3 switch and tag vlan 1 and 3 to port 48 with cli commands for this setup. and also to untag ports 2-10 for computers
192.168.1.1 is a Linksys WRT610N acting as a router and DHCP server for addresses .100 to .150 192.168.1.2 is TEW-639 with DHCP turned off and connected to the Lynksys via one of the LAN ports.
I then have a FosCam camera with IP 192.168.1.010, connected either wirelessly or via a wire on a LAN port to the TEW-639W.
Here is my problem: If the FosCam is connected wirelessly to the TEW-639W I am unable to see it from any device connected to the Linksys. If I connect the FosCam via a wire to a LAN port on the TEW-639W then I can see it from a device connected to the Linksys device.If a device is connected to the network via the TEW-639, I can see the FosCam whether it is hardwired or wirelessly connected to the TEW-639. What am I doing wrong?Why can I not see the wireless connections on the TEW-639 from a Linksys connected device?,The setup is that the internet comes in and is connected to the Linksys, which then via LAN cable and LAN ports on both devices is connected to the TEW-639, which is then connected to the camera.
I am migrating an a group of workstations that run a fire system from one software to another. The current workstations run the following info:123.123.123.xxx 255.255.255.0The new workstations run:100.100.100.xxx 255.255.255.0There is a central switch location using a GE-DSG-244 Layer 2+ Managed switch. There are two remote location using GE-DS-82 Managed Switches.The two networks must remain isolated, yet use the same fiber communications. The central switch connects to the two location using MM Fiber. From my research I believe I need to use the 802.1q standard to allow port trunking between the two switches.
I have got my ccna voice lab configured and is up and running, my switch is configured with 2 differents Vlans (Data & Voice) and the fa 0/1 is configured as trunk port connecting to the CME router. I can telnet or ssh to all the devices on the network but only the switch in not accepting the request the only message I am getting is "request timeout".
I work in a school department and wanted to hardwire two computers in my class using a workgroup switch. I only had one data port in my class. The tech guy told me the switch could cause the entire network to crash. Is that true? I thought a switch was just a passthrough device.
I went out and bought a linksys 5 port workgroup switch. I tried to hook my internet into it and my other computers into it , THINKING, I would be able to get internet on all. No go. I can get inter net on one, as you can tell. but all others nothing. and to make matters worse i got win 2000, win xp pro, and linux that I like to get online.. I have : renewed IP's assin Ip's refresh, purge dns. rebooted. all and rebooted in diferent orders. double checked connections, tested all lines. The network is on a rj45 ethernet .
I'm doing some tesing in SFE2000P linksys switch about the TACACS authentication. I have configured the switch accodringly to point my ACS server with key string. Now, I'm able to login into the switch with TACACS account in HTTP/HTTPS only and but, not with the TELNET access.
Still Switch is authenticating with the local user account only, when in TELNET access method.
I have an SG300 authenticating telnet login to a RADIUS server. It allows me to log in at Priv level 1. when I try and enter Priv 15 mode, I'm prompted for a password which I don't appear to be able to set anywhere or know.
If I remove RADIUS and go back to Local authentication, telnet logs me in at Priv15 immediately.
I want to remotely access Cisco 500 switches via TELNET and WEB BASED from a server. I dont know the ip addresses for Cisco 500 switches which are configured as backbone which the ip address assigned on the network is static ip address. Specifically I want to get their configuations inorder to get their specified assigned vlans on the network. I know the ip addresses for their specified cisco 500 switches' gateways. I know that cisco 500 switches can be accesses through web. Is there other ways to solve the problem apart from going onsite and connect to the cisco 500 switches using network cable since cisco 500 swithes dont have console ports?
