Port Has Not Finished The Transmission - How To Reuse (56789)
Jun 21, 2011
I am dropping a FIN packet in the server and sending the following request from the client
curl --local-port 56789 http://servername
At this point a session is created for the port no 56789.
Immediately ,(the port has not finished the transmission yet) , I am sending another request using the same port as following.
curl --local-port 56789 http://servername
Now the following error occurs .
curl: (7) bind failure: Address already in use
My question is how to reuse the same port (56789) again in this situation?

i have a 5500 series WLC connected to a switch through a trunk port with 2 v WLClans. the connection works fine, but sometimes it loses connectivity. it works again rebooting the wlc.
When the problem presented, i checked the cpd neighbors on switch and it didn't show the wlc, and i checked the cdp neighbors on WLC and this shows the switch in its neighbors list. i also checked the port counters on WLC and the receiver counters keep increasing, but the transmission counters remains in the same value. then i can see that only the TX side on the controller is down, if i restart the WLC the problem disappear temporarily.
Is there a misconfiguration or a wlc bug related to this behavior?
The switch is a Catalyst 3560
The WLC controller code is 6.0.188.0

The coaxial"or any other metal cable" was using for transmission signals(before fiber optic) the coaxial need repeater every 2 or 3 Kilo meter,because the signal will be attenuation when pass through the cable,when we transmission electricity to far places ,we use transformer to rising the voltage to 10000 or 100000 volt

We have a rather strange issue, and I'm not sure it's really a problem with the ACE or not. We created an HTTP parameter map called "TCPreuse" and applied it to a virtual server. A show conn detail displays "[ conn in reuse pool : FALSE]" for all connections pertaining to this virtual server. The rserver in question is Linux(Ubuntu) + Apache.Next we applied the HTTP parameter map to another virtual server - this time IIS7 + Windows Server 2008. There are plenty of entries "[ conn in reuse pool : TRUE ]" when I do a "show conn detail".What could the web servers be doing differently that would cause the connection reuse to work on one virtual server and not the other?

I need to implement VSS on 6500 equipped with Sup720-10GE and WS-X6704; considering that this last 10G card doesn't support VSL, I need to realize VSS interchassis connections on Supervisor 10G interfaces, but I only have X2-10G-LR. Considering that the 2 6500 are in short distance (few meters): is it possible to use 10G long range optics and, if yes, do I need some additional patch?

I try to make session-reuse working on an ACE-4710 Version A5(1.0) without success. Actually, I am facing the problem of the high number of backend HTTP connections that must pass through a firewall. I want to reduce this amount of open sessions with real servers by allowing the ACE to establish permament TCP connections with each rserver. However, it does not work as I expected. I still see individual TCP sessions established and closed after each GET - 200OK exchange. The parameter-map I have to enable this feature is as follows :
parameter-map type http PERF_YHA_HTTP_PARAM
persistence-rebalance
set header-maxparse-length 65535
set content-maxparse-length 65535
server-conn reuse
Note : I use PAT, on the backend, as required by the session-reuse feature
My questions are the followings :How many sessions the ACE would establish with a specific rserver ? only one ? one per TCP option set ?How much time a backend session would last if kept idle for a certain time ?What End Points must share the same TCP options to make sure session-reuse works ? Client to ACE ? ACE to rserver ? all together ?

I recently bought the Dlink DIR-655 router and I have a Dlink DNS 323 nas. I have them connected and working. When I send data from my PC to the DNS 323, i'm doing about 6MB/s. when I'm sending data from DNS 323 to my PC, i'm doing about 30MB/s. all 3 devices have the 1000 Mbps enabled and Jumbo frames is enabled on the DNS 323 and my PC. is this normal?

I am trying to lower the transmission power on my WAG160N. I thought it should be an option in my advanced wireless settings of the web based setup page, however there is only transmission rate, n transmission rate and cts protection mode.

For an N300 model F9K1002V4 router, how can I tell if it's transmitting in N mode? I have two newer laptops that are capable of receiving the 802.11N signal but are only receiving at 54mbps. The router is set to transmit at b/g/n rates.

I would like to connect my 1841 to the equipment that has RS-422 interface in order to transmit data. I have to buy one WIC-1T to support it. However, I am not sure that this module will be able to support RS-422 or not (As I can see there is DB25 which is the interface of RS-422, but I realize that RS-232 also has 25 pins.)

The LSRefreshtime is 30 minutes in OSPF as per rfc 2328, So the router LSA will start after this time(30 minutes). By using router lsa only the Link State Database will be updated. Suppose the datatransmission is started when it(router) is switched on. by using Link State Database only the routing table will be updated.

Is is possible to run Transmission or Google Chrome only using OpenVPN? Other applications should use default connection (eth0) since I am connected to Intranet which won't be accessible if all traffic is routed through VPN. I am using Ubuntu 12.10 and some Premium VPN server (similar to HMS VPN)

1. Does Linksys WAG320N support USB printer? Can I connect a printer to USB-port and send some text to print from notebook via wi-fi?
2. The fact is that I have a cheap, simple chinese WiFi-ADSL-modem ZTE, which has 3 modes - low / medium / high for WI-FI signal. So, the signal is transmitted by ZTE at LOW-level is equivalent to signal, which now sends my WAG320N. When I turn ZTE on high-level, then the range of wi-fi signal increases much, comparing with the range given by WAG320N. So, where can I turn on high-mode in my WAG320N?

I have had a DIR-655 for years, and this is a treat - channeling everything from IPTV, to a fast fiber connection, transfers - no sweats.
Then I had to setup a router for a friend, and recommended the DIR-615.
Setup the router, and max it would connect with was 150mb - I changed the settings accordingly: auto channel scan channel width: auto 20/40mhz
So this "opened" up the 300mb speed - however only for 5 mins, then it falls down to 150mb.
My laptop (lenovo) connects to the dir-655 just fine at full speed, and this is also the machine I used for testing the dir-615.
It's ax Hx firmware, FW: 8.04
What I can conclude by using inssider, and xirrus wifi inspector is that it generates 2 channels - and then after 5mins of connectivity looses a channel, and then the speed drops.
I got a new router from the dealer, same issue. Then a friend of mine lent me an ancient dir-615, and interestingly enough this had the same configuration option of "Transmission rate" in the wireless settings page! Just like the dir-655. and also connects at 300mb...

If I send video file(overall bit rate is 17.5Mbps) to client with 2.4Ghz band, it always freezes and go repeatedly around 1 second interval. the distance around 10m away without any wall, open space actually.
But same condition with above, cheaper wireless router no problem at all. It happens only with EA4500. And there are no any parameters setting menu actually.

I have had trouble to verify the support wireless speed and band that CISCO891W-AGN-A-K9 supports. I saw on a vendor website that it supports a max wireless transmission speed of 54Mbps but this seems low for what is supposed to be the current model wireless router which is supports 802.11n. What the maximum supported wireless speed and whether 5Ghz is supported? Plus I am thinking about purchasing it for my home wireless network (upgrading from an 871W).

I've got an AIR-AP1142N-E-K9 access point, i've got the Radio0-802.11n(2.4ghz) enabled and the 5.0ghz disabled.
i've got my client real close to the AP and i only get a connection speed of 72Mbs.
Shouldn't i get 150mbs? Maybe some wrong configuration?

the only way i can get 300mbps from this router is by having these settings, it seems the only valid settings to get 300mbps from the router are the following:
Network Mode: mixed
Channel Width: auto (20mhz or 40mhz)
Channel : 1
if i leave the channel to auto it won't show up as 300.on top of that it doesn't want to stay at 300mbps for very long, sometimes its max rate in inSSDer is only 144 or 156mbps. its the weirdest thing, i think this version of the firmware seems to forget to check for how fast its wireless transmit speed is.When it reboots it only transmits at 144 or 156mbps. i have to go in the basic wireless page and just save the settings to reset it to 300, i don't even have to change anything, it resets its max rated speed back up to 300mbps.and more importantly, are the devs aware of this problem for the e1200 v2 ?

I'm trying to modify the power transmission control of multiple Lightweight Access Points (1131 AG E K9) at one single time on WLC 4400 or WCS.It is effectively possible to configure the power transmission per LAP and in global on WLC 4400 but i need to configure it per group of LAPs =i.e group X of 10 LAPs will have a power Threshold of X -dBm and group Y of 15 LAPs with Y -dBm.

I have been disappointed by the range of the EA4500 compared to previous routers, but I am most puzzled by it's behavior. I may get an "excellent" connection close to the router (one room away) and speeds up to 65 Mps, but after a few minutes of surfing the web the signal strength and speed can drop substantially.
The problem is the worst at a distance (one floor down in our house, maybe 30 feet away in total) where the signal strength may start at "good" and a speed of perhaps 30 Mps, but then after 3-4 minutes drops to "poor" and maybe 5 Mps.

I've been using a WRT120N on a local area connection.The WRT120N acts as a gateway and also to connect to the PPOE connection, via a bridged adsl modem.I've noticed that the LAN port 1 was flashing although the network cable was disconnected from the physical port. I've restarted a few times but to no avail as well. Ever since that, I've noticed that connection through cable are unstable and hard.Now, I'm not able to reset or upgrade the router's firmware.Is there any other way to be done so that I can get this router working as normal again.

I am having difficulty following the logic of the port-translation. Here is the configuration on a 5505 with 8.3,So I would have thought the outside access-list should reference the 'mapped' port but even with 3398 open I cannot remote desktop to the host. If I open 3389 then I can connect successfully.

On the supervisor card of a cisco 6500 series, according to the following link, [URL] it only has 2 uplink ports on the card. Would I be correct in assuming that I only have those to ports that I can configure IP addresses on?
The cisco that is being devlivere is coming with a 48 port switch and 24 port fibre switch. Could I change any of those ports into a router port and configure IP addresses on those?
The supervisor card is a ws-sup-720-3b the 48 port switch is a ws-x6748-ge-tx the 24 port fibre switch is ws-x6724-sfp

I'm trying to enable port security on several 4507R's. When I try to configure a range of ports the switch will randomly put 1 or 2 in err-disable. It's different every time I apply the config to the same group of ports. However if I do them one at a time it seems to work. But I really don't want to configure 6 fully populated switches one port at a time. We also have a lot of 3750's and they gave me no problem using a port range. [code]
