D-Link DIR-601 :: Loosing Telnet Connection When Leaving Session Idle For Only Few Minutes
Mar 4, 2013
Not sure where the best place to drop this question. It is a DIR-601 router. I have it configured in the virtual servers list as; internal system ip, public port/private port both 23, protocal tcp with inbound filter, allow all and schedule set to always. I have a second system with a different public port. I can connect to either one but after a short amount of idle time it appears to just drop the connection.
im loosing connection every few minutes , tried ipconfig /release , ipconfig /renew and im getting this error every time : An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out. After typing ipconfig /all DHCP address is 255.255.255.255 and this IP 192.168.100.10. Tried other things like flushdns / netsh commands and nothing want to work. My connection works only after i restart my modem. Modem type Ubee 3236. The modem is new got it 4 days ago. And also why i cant access the modem configuration page by typing my default gateway in browser ?

I have a big problem with my Cisco 1841 and the WIC-1AM-V2 in Slot 0.I got the task, to test if it is possible, to build up a connection (Dial on Demand Routing) to a remote modem, which is connected to a console port of another Cisco 1841, with the integrated modem card over POTS from the CLI of the router. My router will only dial out to the remote modems and only if its needed.I am connected to the router with the integrated modem card over a console cable on the console port. The remote modem is also connected to the console port of the remote Cisco 1841.
I found out, with my Dialer Profile configuration, it is possible to build up a connection. I configured a dialer list, that specifies that all ip traffic is permitted an interesting for my dialer interface. So a telnet or ping brings up my dialer, which brings up my Async interface. With the "show line" command, I can see that the TTY line, connected with the Async0/0/0 Interface is in use for 5 minutes, because of the "exec-timeout 5 0", which is configured on the remote router. Now the problem is, in this 5 minutes, I can not use a remote telnet on this line with my loopback interface, because the line is already in use and I get a "connection refused". The first telnet I use runs in a timeout, because the remote host is not responding. When I dial out directly from the modem card and not from the CLI with the AT-commands, I get also the connection and with a return i get the login prompt. I will post my actual config, so that you can see maybe a mistake I did or which command I must use, to get a working connection. [code]
I have an SG300-20 here for testing (firmware: 1.1.2.0, boot version: 1.0.0.4, language version: 1.1.1.6 English). Everything seems to work on it, except, that if I choose Radius authentication by mac address only, then the switch does not honor the Idle-Timeout and Session-Timeout attributes from the Radius server (freeradius).
The setup is the following: I have a no name access point plugged in to switch port gi1. The port gi1 is set up for Radius authentication by mac address only. The access point itself is authenticated, no problem with that. If I connect through the access point by (say) a mobile phone, it is authenticated, no problem. The radius server does send the Idle-Timeout and Session-Timeout attributes, I checked it by running "freeradius -X", both are set to 30 seconds. Then I turn off the wireless card in my mobile phone and check the dot1x users by "show dot1x users". My mobile phone's mac address remains there for 5-10 minutes, so the Idle-Timeout and Session-Timeout does not work.
Another way I could resolv this problem is by explicitely asking the switch to reauthenticate the user. Unfortunately there is no CLI command to do just that, I can do however a reauthentication on a port using "dot1x re-authenticate gi1" (for example). But it does not work as it is expected: the switch uses the stored mac-address to reauthenticate the user, so nothing changes on the port (unless something changes in the radius server). I think it should work like the following: remove the authenticated user from the port, and whenever that mac address makes some network traffic, then reauthenticate as if it were a completely new connection. BTW: it would work for me also if I could just remove an authenticated user from a port, but I did not find a command to do that.
As a last resort I can simply shutdown the port, bring it up again ("shutdown" and "no shutdown" in the interface config), then all users are removed from the port and they all mush reauthenticate. But it causes a network outage for a couple of seconds for all users on that port, on a busy access point it is quite disturbing, and it is not an elegant way to do this.
So my actual question is: is there a way to remove an authenticated user either automatically (Idle-Timeout and Session-Timeout) or manually from this switch?
I enclose the relevant part of the running config.
My new EA 2700 disconnects from the internet if the desktop is idle for more than 30 minutes. needs to be unplugged for a few minutes then it will reconnect. This is an unacceptable situation and this thing will be tossed if it cannot be fixed. Can this be reset so it won't disconnect? or do I need to replace it with a product from another company?
We installed a DIR-615 Vers. E1 FV. 5.00NA and since then i-Pods and i-Pads keep dropping wi-fi connections. All wireless PC's and printers are working fine. We have configured the wireless as:Mixed 802.11 n,g and b. Auto channel csan enabled, using channel 6. Wireless security is WPA-Personnal. WPA is configured as Auto, TKIP and AES with a pre-shared key.
I have just purchased a DCS 2121 (I assume that it is a similar model to the DCS 920 in US).I have this setup:
- Connected the DCS 2121 wireless to my Belkin Router with a fixed IP address. Firmware version 1.4 is installed on the camera.
- I have a Synology 209 NAS server with surveillance station that I have connected to the Camera.
I all works fine for 5 minutes to a couple of hours at which point the DCS 2121 loose connection to the Router and does not try to reconnect. If I turn the Cam on and off it will reconnect - and then loose connection again af a short time.This is totally frustrating since the purpose of the Cam is to work as a surveillance cam - it kinda loose its value by not being connected...
Bought a Dir-600 from challenger, used it for 3 months and started expericing the common problems of loosing internet connection highlighted by many users here and in other forums. Would always have to do a modem / router power cycle to get it going again.Slightly after 3 months... the thing went dead. Can power up but no response. Cannot detect the modem.Got a one-for-one exchange at Funan. Used the 2nd one for less than 2 months. It just went dead on me! Same problem...
Any issues with pasting scripts into a Nexus 7K and having the scripts get all messed up even though they are logically correct? I've had this issue over the years with IOS devices and the console port and tweaking some of the line feed/character delays fixes the issue but that was always with the console port and not a telnet session. Telnet has always worked flawlessly on IOS.
I've determined that if I tweak my line feed delay up to 1000ms it seems to work fine, but it just doesn't make sense to me that I have to do that.I have a customer with 3300 ACL lines that need to be put into a Nexus as part of a migration from 6500 to Nexus. And yes, I've already tried to convice them to offload these VLANs behind an ASA!
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode 3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.
we are facing issue for unstability of EIGRP neighbor with ISP router.Both router are connected via 3750 switch.There is no misconfiguration or physical media issue.I found the SDM template on the middle switch is desktop default, does this will impact ? [code]
I have a DIR-615, hardware version: C1, firmware version 3.12NA and my issue is that it keeps dropping my VPN connection after 12 minutes. Sometimes it'll go longer than 12 minutes but on average right at 12 minutes of my connection, it drops. This happens whether I'm using the wireless or hard wired to the router. As a test, I ran a continuous ping on a computer on my internal network and also to a computer on my corporate network. When I'm VPN'd in, both pings are successful. Once the router kills my VPN session, the pings to my internal network are successful. So the router isn't rebooting or anything like that. My VPN session will automatically reconnect, but I'm stumped.
I'm trying to hook up a dap-1522 to an SMC8014WG wireless router. All goes well for about 10 minutes then the SMC drops all wireless connections except the connection to the 1522, and loses internet connectivity.There are several other wireless devices connected to the SMC but none of them causes it to go down.
I bought a DIR-600 a couple of months ago. Days later started experiencing problems, connection would drop, and only way to restore connection was to reset the router.It has its password configured, a secure wireless connection also configured, and Wan Ping is disabled.Yesterday I called D-Link support, and they asked me to update firmware (from 2.03 to 2.05). I did, but problem still here.Today I realized that there is a log section, and when I entered this is what I found?
LAN connection gets disabled by itself on idle. Sometimes BSODs.A few days ago I tried connecting a MBlaze modem to my laptop (Windows 7 Ultimate 32 bit) to access internet. But it resulted in instant BSOD everytime.I deleted the modem software after that & didn't try to connect it again.But now, whenever I connect using my LAN broadband, connection works fine as long as I am continuously browsing something. But as soon as I stop browsing and it goes in idle mode in about 10-15 minutes, the connection gets disconnected. In the adapter properties, it shows that the driver is working properly. If I try to disable or uninstall it it doesn't give a response. The only solution to this is a forced shutdown & restart, after which it works fine untill not idle. I am not able to download anything because of this.I tried many things like reinstalling the network adapter driver, unchecking the power management feature, resetting the connection, etc. but nothing is working.
My nephew's XBox (he's an on line gamer, and quite a serious one for that matter...) seems to boot him off line when someone uses the phone or goes on line on another computer. The house is quite far from the exchange so the average down speed is only 1.75-2 Mbps. This connection is through a BT Infinity R/S/F and I wanted to know if we could just add another R/S/F device and subnet the games console into it's own DMZ with full bandwidth access and then the normal broadband & phone on a different subnet also with full bandwidth access?
I recently started having trouble with my VPN clients loosing connection.I can create the conenction, work with it for a while, and then loose connectivity.Timing seems to be dependent on the activity over the connection.More activity, the conenction stops working sooner.
The cleint doesn't disconnect, I just can't access anything from the client.Disconnecting and reconnecting the client fixes the problem, temporarily depending on how much data I'm transferring.This works 90% of the time.The other 10% if I wait 30-45 minutes, and try again.. It works...with the same results...
It was originally isolated to a Win 2003 server that I was using as the client.It is now happening on my Win XP client as well.I'm using the AnyConnect client ver. 2.5.2014 with the VPN service on the UC520.Which I beleive, is similar to the ASA 5500 series VPN device.I am running ver 8.1.0 on the UC 520, and I can't remember if this started after upgrading to the new software.
We are using the cisco sa540 router and shrew VPN to connect to our buiness network, mostly to connect to the workstations with RDP. Now we wonder if it posible that the connection will disconnect automaticly after an idle time of for example 30 minutes. And if so, how can i configure it?
Ok, so if i open Utorrent and let it download for 10 minutes i loose my internet connection. I usually will disconnect my cat5 cable and plug it back in and it doesn't work so i would open up the CMD line and try to reset the network connection but it doesn't respond so the only way i can reset it is to restart the the computerI've tried reinstalling Utorrent but i still keep loosing my connection, yet all the while I am able to run netflix on my PS3 so my internet connection isn't going down.
I have ASA 5510 with 8.2.4 and 8.0.x OS and all seem to have common problem of idle TCP connections not timing out. The host to host connections are coming over VPN tunnels. I have default timeouts on all the firewalls. I have tried changing global timeouts and as well as host specific timeouts using MPF but doesn't work at all ! The problem is when TCP connections are sitting idle in conn table for days and when connection limit of 50,000 conns reach the firewall starts behaving unpredictably dropping packets or unresponsive! I need the unused idle connections to timeout which is NOT happening either by changing global values or MPF.
my linksys e3000 router loses connection quite often. E.G. we lost power last night and i tried resetting the router but it didnt work so I had to uninstall and then reinstall the router. A few other times it would lose connection for no apparent reason.
I have recently changed my router from Netgear to TalkTalk because of an intermittent signal, no problem with my desktop ethernet or laptop wireless or tablet but I keep loosing connection with my WII internet connection for Netflix.
My macbook keeps loosing it's wireless connection after being idle, when I start up I have to find my router and highlight it and connect and if it's idle it losers it's connection all the time.I tried resetting the router to default and started over I also tried every imaginable way of saving my password and connection but I can't find a way I've been into the routers security,trouble shooting,wireless, what's not holding it's connection to my MACBOOK? my iphone 5, ipad, and roku all hold
We are in a hotel that allows us to use their router with a Hawking 300N expander. We seem to lose connection each time their router gets a new IP address. The router seems to lose connection frequently. Is there a setting in the expander that will allow the expander to "follow" the DHCP address of the router without having to take it down and go thru the setup each time.
I have several computers and printers connected to a WRT120N router which is connected to 10mpbs DSL. The computers are all running WIN7 and are hardwired to the router. On the one PC, it keeps losing network connection. I've tried upgrading the router's firmware, reset, etc. to no avail.
I think it may be related to the same IP address being assigned to multiple machines connected to the router. Is there a way to set specific IP addresses to each item connected to the router to see?
My IP provider has upgraded my broadband speed in early Jan. They require ADSL2. It seems to coincide with this date that I keep loosing my internet connection on a regular basis, say every 2 days or so, but not consistent. The cure is to unplug the linksys WAG200G ADSL home gateway. Plug it in again and all is well, until the next time. On the box it says the until is ADSL2/2+ compliant.
I've recently upgraded from a WAG54GS to the WAG320N. It seems to work OK for a period then looses the connetion to the Internet - DSL light on but not the Internet light. Normally I need to re-set the router to re-connect (either through the back switch or through the setup page)
