Jabber 9.2 Failback from TCP 5222 to TCP 443

Hi all,
if i check the deployment guide for J4W i see that it supports failback to https, if XMPP (TCP 5222) is not available.
http://www.cisco.com/en/US/docs/voice_ip_comm/jabber/Windows/9_2/JABW_BK_C9731738_00_jabber-windows-install-config_chapter_010.html#JABW_RF_P3E0FDE4_00
We have noticed that the feature is not available in our cloud based deployment.
Do i have to enable eny specific setting in Webex Connect Admin?
Any other experiences?
Steffen

One of us does not understand the feature.
Of course is 5222 blocked, because I want to see jabber doing a fail back to https.
Do I misunderstand the fail back?

Cisco E900 ports 1990/tcp and 5916/tcp open on the LAN. Cannot close them.

Hello,
I just bought a Cisco Linksys E900 wireless router. Can someone explain to me why the router (192.168.1.1 on my case) has ports 1990/tcp and 5916/tcp open on the LAN?? I cannot find a way to close those ports.
Just do a simple:
telnet 192.168.1.1 1990
or
telnet 192.168.1.1 5916
and you'll see those ports are open.
1990/tcp = Cisco STUN Priority 1 port
5916/tcp = I have no idea
Every client on the LAN (wired and wireless) can connect to those ports on the router. I do not want that to happen. It is unncessary and it is just not secure. I only want the router to have port 443 open on the LAN for the web mgmt interface. I do not want any other unncessary port open.
It would be great to have a response from Cisco directly.
Thank you for your time.

Thank you for your response.
The router is already updated to the latest firmware (1.0.04 Build 1).
I had to do the update as soon as I opened the box because the default firmware had an incredible serious bug: after setting up the web management interface on the LAN to work over SSL, it was impossible to access the interface because of an SSL bug in the router. The bug is in the release notes of the firmware... that alone says a lot about the very very poor quality of this router.. you can't have that kind of bug in a finished product....
I was able to close port 1990/tcp by disabling WPS in the router, although doing so was pure luck since the router's UI is terrible..
5916/tcp is still open.. since I was able to close 1990/tcp I don't think this is a defective router.. I cannot return a router to the store just because it leaves a port open, the store, sadly, will not take it back... so please Cisco, can you help with this? this product is faulty, it doesn't work as expected, it's your responsability.. please help
Reset the router manually then reconfigure the settings.

Handle Received data of Multiple TCP clients on TCP Server by displaying them into Datagrid

Hello All,
I have developed a C# based TCP server GUI application which is accepting the data from multiple TCP clients on TCP server.
The data i am receiving from TCP clients is a 32 bit data. In my application multiple TCP client data goes like this:
00012331100025123000124510321562
01112563110002512456012451032125 and so on...
Now i want those data of the TCP clients to be parsed into 4 bits first and display it in 8 columns (32/4=8) of (say) datagrid as each 4 bit represents some characteristics of the TCP client. The same thing
should work for next TCP client on second row of datagrid.
Can you give me some suggestion or an example how to go about this? Any help would be appreciated.
Thank you in advance.
Here is my code for receiving data from multiple TCP clients.
void m_Terminal_MessageRecived(Socket socket, byte[] buffer)
string message = ConvertBytesToString(buffer, buffer.Length);
PublishMessage(listMessages, string.Format("Sockets: {0}", message));
// Send Echo
// m_ServerTerminal.DistributeMessage(buffer);
private string ConvertBytesToString(byte[] bytes, int iRx)
char[] chars = new char[iRx + 1];
System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder();
d.GetChars(bytes, 0, iRx, chars, 0);
string szData = new string(chars);
return szData;

Now i want those data of the TCP clients to be parsed into 4 bits first and display it in 8 columns (32/4=8) of (say) datagrid as each 4 bit represents some characteristics of the TCP client. The same thing
should work for next TCP client on second row of datagrid
If mean it's a Windows Forms application and you want to display those bits in a DataGridView control, then please see these threads:

Stop tcp listen and tcp read

Hi all,
if i use the tcp listen and tcp read blocks with a time out of -1, how can i stop their execution if they are waiting for incoming connection or data?
The tcp read block is in a while loop and the stop button state isn't evaluated, since the read block is in wait.
some one can tell me a solution to this problem compatible with S-RIO target device?
thanks
Solved!
Go to Solution.

i try to explain better with an example.
1) run the server
2) run the client
3) try to stop the server without stopping the client --> the server never stops due to the infinite timeout on the reader.
note: the client doesn't close the connection after sending "hallo" 4 times.
the question is: is it possible to have the server waiting for data and the stop but evaluated when pushed?

Extreme Base station can't extend signal from Mini desktop ?TCP/IP settings

I have a Mac Mini connected to DSL via a lynksys 8 port workgroup switch. I had 6 rooms in my house connected to the router by ethernet wiring. Worked great for several years. Now 2 rooms cabling seems to have gone bad (mice or squirrels, maybe). To avoid rewiring the connection outlets or pulling wire again (Ugh!), we bought an extreme base station. It transmits the internet signal fine when connected to the ethernet network (roaming), but I cannot get it to allow clients to access the internet in WDS mode.
The base station is in a central location where there is not an ethernet jack. It picks up the airport signal from the Mini (with extreme card and yes, I have the MAC address of the Mini chosen).
Internet connection is "shared" on the Mini and the laptops have no trouble accessing internet within close range of the Mini. The laptops can't access the internet through the base station. I suspect it's how the TCP/IP is assigned. I have tried every possible combination in the Airport Admin Utility.
In the WDS diagrams, it always shows 2 or more Base stations, never a Desktop and a Base. Are these incompatible?

...but can't figure out how for the Mini....
When you select "Share your Internet connection with AirPort-equipped computers," click AirPort Options to give your network a name and password.
Since they are the "same" network does it matter?
If one has no encryption or is using weaker encryption it will be the weak link for others to access your entire network.
Normally, if you want to seamlessly roam between the 2 wireless networks, ensure that they are using the same network name (SSID), same encryption type, same encryption level, and same encryption password. However any wireless device connecting to the Mac mini's network will be on a separate subnet.
Now I've got to figure out how to get files off the Office Desktop from the laptops, should I set up afp for airport or ethernet?
Enable Personal File Sharing on the Desktop.

Read data from serial port or TCP port of frontend PC

Hello Friends,
I have requirement to read data from device connected to frontend PC which will provide meter reading data.
Vendor has given me two option.
1. Device can be connected to seiral port and data transfer will be done through MODBUS RTU protocol.In that case data need to capture from serial port.
2. Device can be connected to TCP port and Socket program can be provided for data transfer. In that case SAP will act as client and communicate with TCP port.
There will be multiple workstation with individual meters connected to them.
I am aware of text file interfacing through front end tools using custom code using VB,JAVA or others.
Is there any solution availble to achieve above things using ABAP other than text file , like direct communication?
I am using ECC 6.0.

Hello,
Socket programming in not available on ABAP, but you may use RFC for the same.

Jabber issues after waking from sleep

When i wake my air from sleep, jabber is offline, and tells me that it had issue, but when i pull down the tab to say i am availible it will not connect, no message no anything. but if i go to file and accounts and uncheck gmail, and recheck it. It give me a message that it will be unsecure, and connects. Is there a setting i should have that i am missing, maybe a port i should use instead?
thanks

Sign out of gtalk
go to preferences>accounts in Messages.
select gmail from the accounts
select server setting (the far right option)
make sure it is

Cisco Jabber MRA : Cannot login from internet

Dear all,
I have the following : CUCM 10.5, IM & P 10.5, VCS C 8.2, VCS E 8.2. CUCM, IM & P, VCS C are located in the internal network. VCS E is located in the DMZ. I'm sure that firewall configuration is already opened according to Deployment Guide.
I've checked UC status in VCS C and VCS E, Unified Communications services is active, traversal zone is active.
Does anybody have any idea?
Thanks.

I had a look at the jabber logs that were provided and the issue appears to be host name resolution. (atleast in this login attempt)
The client is able to successfully retrieve the collab-edge record for the "telkom.co.id" domain.
DNS query succeeded for '_collab-edge._tls.telkom.co.id.'
The client then tries to send the get_edge_config to the following address:
https://ewedge-4-uc-st.telkom.co.id.telkom.co.id:8443/dGVsa29tLmNvLmlk/get_edge_config
What's odd about this is that the request has the domain listed twice. Due to this the login is failing with a "Could not resolve host" error.
2014-08-19 16:35:47,444 INFO [0x000025a8] [ls\src\http\CurlAnswerEvaluator.cpp(108)] [csf.httpclient] [http::CurlAnswerEvaluator::curlCodeToResult] - curlCode=[6] error message=[Could not resolve host: ewedge-2-uc-st.telkom.co.id.telkom.co.id] result=[UNRESOLVED_HOST_ERROR]

These logs suggest that there is an error with the collab-edge response. For some reason it's listed with the domain twice. I would double check your collab-edge SRV to see how you have it formatted.
I hope this helps.

Switching from Named Pipes to Tcp/Ip sockets : can I use the same DB or will I loose my data?

Hi,
we use MDT 2013 in conjunction with a local SQL Express 2012 database. I configured MDT to use Named Pipes but I want to switch to TCP/IP sockets. Is it possible to change that Network Library for an existing database? Am I going to loose the contents of
the existing db? Thanks for your insights.
Paul

Just did a testrun with a test deployment share. Made a db with Named Pipes, filled in some values. Created a new db and I was able to choose between some existing databases. I chose the test db and yes all the values are in it.
Next I tried it with my main db and indeed nothing is lost. Pfjew.

SP7 tcp and 681j tcp broken for me.

Hello all,
I have this very long and storied journey that I hope you will read, as TCP is broken for me.
Facts:
Netware OES 6.5 sp7 and TCP681J domestic and Null.
TCP680b (working)
Dell 2650 server with Broadcom NiC, b57.lan version 10.41 (newest from dell and came with sp7)
PIX 515 code 8.0.2 performing dynamic and static NAT, with a DMZ
Novell DNS/DHCP
eDir 8.8 sp2
Okay here we go.
I was in a long battle with the Bordermanger people telling them that TCP was broken. Today I took my BM server out of the tree and rebuilt it from ground up. The problems I am having have nothing to do with BM as when I built this computer from scratch and just did routing, DNS doesn't work.
Okay, so I have a BRAND NEW server that I just built. I have two network interfaces, internal and external. The external is connect directly to the PIX 515 and the internal is connected directly to our internal network.
So, I turn on routing on this new server with SP7 on it, and I can not do a DNS lookup from the server. None of my DNS servers can do lookups, and none of my workstations pointing to my internal DNS servers can do lookups. My DNS servers have pointers to external DNS servers which are running. I can not even see my PIX firewall from inside my network, yet the BM can ping it just fine.
I patched to 681J and tried both Domestic and Null and got the same result.
Then I took the TCP 680b (TCP.NLM, TCPIP.NLM, BSDSOCK.NLM) and put it on the server. WOW, I CAN RESOLVE AGAIN! I can even browse the internet and get to my pix and DMZ.
So why don't I just stay this way? Because the connection to the PIX randomly drops. Again, I do not even have BM installed on this server. If I did, I would have 3.8 sp5 ir1.
Now, if I do the same thing with a POS workstation, build a Netware OES 6.5 sp7 server, everything works fine. Server hardware you ask. Maybe, but it must be specific to Dell 2650 and Broadcom NIC's because I built another server using the EXACT same hardware and got the same result. I also built this on a test Dell 830 server and it worked just fine.
I have proved this over and over and over again with my colleagues and we still don't get it; that we would be the only people with this problem.
Can someone help?

Sorry

Tom I would seriously check your filtering configs and similar as I am running SP7 OK on 2 BM servers here.
1: Are DNS Queries allowed out through
a: Your PIX IP Filters (plug a machine direcly into your PIX and see if if you can query an external DNS Source)
if a: works
b: Your Netware IP Filters (Test drop your filters and see if you can ping an external host using its dns name
What is yor DNS Configuration?
Are your DNS Servers doing route lookups? or checking your ISP's DNS.
Agreed with Massimo. a quick bit of Wireshark on your DNS Servers might prove extremely helpful.
Hope this helps

TCP Connections vs TCP Flows

Hello:
I'm trying to track activity on a CSS11800 and have been watching TCP Connections with "sh serv summary" and TCP Flows with "sh flows 0.0.0.0". However, there doesn't appear to be any obvious correlation btw these figures.
Can anyone tell me which command will provide the most accurate picture of current user connections?
Does "sh serv summary" display both inbound and outbound connections whereas "sh flows 0.0.0.0 xx.xx.xx.xx" displays inbound connections only??
We often see high numbers of TCP Connections during off hours when there is no activity occuring. Perhaps this is case of browsers being left open which maintains the TCP flow.
Thanks for the insight.
Best regards,
Dan

Hi Gilles:
We have 3 service balanced to a single VIP for one client. We have been using the TCp Conn's from "show service summary" to gauge the activity of the client.
However, this number seems to fluctuate, but never actually goes below roughly 40 per service, even when there are no active flows to the VIP. And it never correlates directly to the number of flows. Would it count 2 conn's for each flow (inbound and outbound)?
Our HTTP keepalives are running as persistant - could this affect the TCP Conn's number?? Or perhaps it's an IOS issue?
Our test environments on both old IOS and 6.10 seem to display the TCP Conn's correctly, as in the number goes up and down with the creation and teardown of TCP flows. But, it seems on a loaded production environment.
Are there any particular concerns relating to the 5.02 image?? We are planning an upgrade very soon.
Regards,
Dan

Getting huge number tcp-retransmissions 7& TCP Dup ACK packets.

Hi,
I was working with a issue, in which we were observing that the citrix application page is freezing intermittently for 5-10secs and again working without any discosnnections.
On troubleshooting I did nt observe any abnormal latency or packet loss on the GRE tunnel from source vlan till server destiantions.
The citrix traffic flows via a GRE tunnel to remote location then via plain internet flows to a internet facing citrix server behind a firewall.
On analyzing the traffic using Ethereal I have observed huge number of duplicate ACK packets and TCP retransmissions, hence i derived it has some thing to do with packet fragmentations.Hence I modified that TCP MSS size to 1400 from 1412.
Hence I modified the GRE tunnel configs as below
Router#sh run int tu 691
interface Tunnel691
description XXXX
ip address X.X.X.41 255.255.255.252
ip mtu 1500
ip tcp adjust-mss 1400
tunnel source Loopback69
tunnel destination X.X.X.X
end
Still there is intermittent issue.Can you pls help me to find out where excatly the issue can lie.

We had a similar issue and issued the following commands and everything is working well.
ip mtu 1476
ip tcp adjust-mss 1436

TCP client and TCP server...

i m doing a project in GUI form, where the client need to enter data in text field and the data will be pass to server to process, for example if client click button "ADD" then a particular data will pass to server and do sth (save data into a file), or if client click button "DELETE", the client is actually call server to delete a particular file stored in server, how can i do it using TCP socket ??

Hi,
Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

Shortly afterwards, I found that ALL my HTTP (80) sites didn't work. I went into the Server.app and found that ALL my sites were now using port 443, rather than the port 80 that they were running on.
Since I have over 100 sites, I need to know how to BULK update them back by removing the certificate they were assigned when I updated that specific cert.
How did I update the certificate? I was looking at the Alerts section of the Server.app, that told me that some were expiring. There was a Replace button and that's what I clicked. I was never warned that it would change ALL my sites from having NO certificate to the certification that I replaced.
Any ideas on how to resolve this issue quickly, without having to open up EACH site and change the certification to NONE (and thus changing the port back to 80)?

There's no bulk update via the GUI [1], which leaves shutting off Server.app and mass-editing the Apache data.
For a bulk change of 443 to 80, something like this should get you started.
FWIW, Do also confirm whether the port 80 sites are still around in the configuration data, as some web browsers are now selecting 443 whenever that's available.
[1] Yes, I'm probably ignoring scripting via AppleScript here. If I have to script something, it'll be the Apache data and not the GUI, and using bash, Python or other such and likely not AppleScript. Local preference.
