***ANSI connection via socket
Hi
I need help!!
How can i establish an ANSI connection via socket??? because the server dont let me connect with a VT100 connection
The book Core Java 2 from Sun has a good discussion on that.
There is a thread in The Water Cooler titled YAT which is a
discussion of that book. Read through it (there are about 3400+ posts).
They should have it. It would take too long for me to re-search my book.
Do a search on the Java site for ANSI or Character Map, you
will probably find documentation and tutorials on it.
Let me know if you can't find them.

Macbook can't connect via L2TP but can via PPTP. iPhone can connect to both
So I've been banging my head up against the wall for the better part of this morning trying to figure this out. Just as a note, I'm 3000 miles from my house and server, but I do have access to it for the time being via PPTP.
Before I left, I verified that I could connect with L2TP on my iphone's 3G network. I was also able to connect at the airport on my Macbook using L2TP. Sometime overnight something changed, and I can't figure out what. I noticed that my phone dropped it's VPN connection saying something like "the connection to the server dropped unexpectedly" or such. After that, I was unable to connect over L2TP on my macbook or iphone. On a whim I tried connecting over PPTP which worked! But only on my macbook. Again on a whim I tried to connect via L2TP on my iphone, and it worked?! I rinsed, lathered and repeated that process over and over again and confirmed that I could only connect over L2TP on my iPhone after connecting on my macbook over PPTP. Also, on my iphone, if I stored the password it wouldn't authenticate (probably not related).
As of this moment I am connected using L2TP on my iphone for the last hour, using it to successfully stream Pandora across US borders, but can't sustain a PPTP connection on my macbook for longer than 10 mins. And I still can't connect over L2TP. So that said here are the client and server logs (ips, domains and usernames masked....) Server and clients are in different timezones:

I made a similar post here - maybe something in there will help you.
One thing I have been able to pinpoint is that the MobileMe Back To My Mac service was causing quite a few issues with being able to connect to the VPN. Once I turn off the service, connection seems to work fine. Although, once I'm connected, I cannot access file sharing. Still waiting for some answers on that. -

NLSRTL Version 10.2.0.4.0 - ProductionOS is AIX 5.3 for Oracle 10 and AIX 6.1 for Oracle 11.
We are currently in the process of migrating some applications from Oracle 10 to 11. Our admins have setup a new development system for us with an Oracle 11 instance. Regarding performance the new system behaves more or less the same than our old, e.g. when executing SQLs we notice hardly any performance differences and those we find are slightly in favour of the new system.
But now we discovered that the time it takes to establish a database connection via SQL*Plus is longer on the Oracle 11 system. Running the following code
sqlplus -s user/pw@database <<END
quit
ENDa thousand times takes ~60s under Oracle 10 but ~140s under Oracle 11. This may not seem much but we are running a test framework consisting of a bunch of shell scripts where several thousand connections are openend via SQL*Plus to execute some SQLs, so that even this small time difference results in rather huge difference in total runtime. The SQLs themself require roughly the same time in both databases, as already mentioned above they are in fact slightly faster in Oracle 11.
To analyze the time difference I ran a trace for the connect with the following parameters in sqlnet.ora
TRACE_LEVEL_CLIENT=4
TRACE_UNIQUE_CLIENT=ONand found out that there is a time difference of about 70ms during the connect handshake:

(1) [22-MAR-2013 13:33:40:618] nscon: got NSPTRS packetAny ideas what could be the reason for this time difference? Something in our network configuration or something else?With local connections - I do not think a TCP packet send from an IP to the same IP, leaves the interface as an actual wire protocol/signal. If I'm correct, then running local connection tests will be mostly useless in checking the actual network infrastructure.
Tests 3 and 4 should be showing the same connection times as the same physical network infrastructure is used - only the direction is reversed in the tests.
I would assume that port settings on the switches and interface settings on the routers treat packets equally in both directions between 2 servers. But this could in part explain the problem if this is not the case. In a case of a router for example, the 1st test's ingress interface is the egress interface of the 2nd test (and vice versa). Configurations can differ substantially between interfaces on the same router. Likewise if there is a firewall - as different rule sets are applied in each test and these rule sets could differ.
So I would not be too quick to state that this is definitely not a network problem. But I agree that based on the small percentage difference (assuming comparable tests), it does not look like a network issue.
The next step is to determine what the delay is between the listener accepting the client connection, and the connection being serviced by a dedicated server process.
This will require listener tracing - tracing the time from when the listener accepted the connection (and parsed the TNS connection string), to handing off the connection to the dedicated server process.
As a comparison test, you can also test shared server connections. Dispatcher processes (of the db instance) register themselves with the listener. The shared server client hand off is thus done to an existing server process - no need for the Listener to make a kernel call to load and initialise an executable image.
Shared connections are typically faster than dedicated connections in this respect.
If there is a major time difference, then it means some kind of issue with the listener dealing with dedicated servers as oppose to dispatcher hand off's. As both connections would have had very similar network transit time - which means the connection time difference is related directly to dealing with a dedicated server connection request and hand off.
You can also substitute the oracle executable with a wrapper - and troubleshoot the actual dedicated server startup. I've only done this with Oracle XE 10.2 though and with local IPC connections. Unsure how robust this will be for testing purposes via TCP using 11g. -
Connect Via RMI To A Remote Service?
Has anyone connected, via RMI, to a remote service within an application module? Currently this seems to wreak havoc upon all future and current ORMI communication to and from the application server in which a model is deployed (or at least within a container). Does anyone have any idea on how to do this correctly?

Whats the difference between sending messages via socket and MQs?With JMS (and the like) your application uses a socket to connect to a central server called a "*Message Broker*". Over this connection it can send or receive messages.
A Message Broker is somewhat analogous to a database server. Multiple clients connect to it to exchange messages. As with a database a client first establishes a connection, then requests specific facilities like subscriptions.
It creates a strong decoupling between sender and receiver and handles stuff like allowing multiple receivers for the same message, queuing of messages for applications not currently running and so on.
(And don't worry, you can get perfectly good message brokers for free such as openMQ and activeMQ.) -

out.write??(Socket)???

The client already knows about the connection (since it connected to the server). I don't know what problem you are trying to solve, but it sounds like you want to give the client som kind of id, and store the connections in a map on the server, and use the client id as key in the map. -

Receiving Image via socket and creating via byte[]...
Hi Folks...
I�m trying to send a WebCam SnapShot to my Midlet running in a PDA via socket..
The method used to send the Image is:
BufferedImage img = toBufferedImage( getScreenShot( getFrameBuffer() ) );
byte[] buf = convertImage( toBufferedImage( img ) );
BASE64Encoder enc64 = new BASE64Encoder();
enc64.encode(buf);
try {
out.writeUTF("IMAGEM");
out.writeInt( buf.length );
out.write( buf );
} catch (IOException e) {
e.printStackTrace();
}So this code get a snapShot from the webCam and returns a BufferedImage. This BufferedImage is converted to a byte[], and later this byte[] is encoded in Base64 format with BASE64Encoder.
In the next step the buffer is sent to the client, the server send the message "IMAGEM", in the sequence the size off the byte[] and then the byte[].
The code that receive the Image byte[]...
private void receiveImageAction(){
byte[] buf;
try {
buf = new byte[ in.readInt() ];
in.read(buf);
Image img = Image.createImage( buf, 0 , buf.length );
viewForm.setMsg("Image created");
viewForm.setImageView(img);
} catch (IOException e) {
viewForm.setMsg( "" + e.toString() );
}catch(Exception e){
viewForm.setMsg( "" + e.toString() );
}When the connection manager receives a message "IMAGEM" the function receiveImageAction is called.
It receives the size off the byte[] and then receive the array.
When I try to create the image using Image.createImage( byte[], int, int ) the exception IllegalArgumentException is throwed...
The exception doesnt have a message...
What is wrong ?
Is the format off my image sent ?
Is my buffer been encoded correctly by the BASE64Encoder class ?Will u try with replacing this line
Image img = Image.createImage( buf, 0 , buf.length );with this line
Image img = Image.createImage( buf, 0 , buf.length-1 ); -
10.5.2 - cannot print with Samsung CLP-510 connected via Airport
After 10.5.2 Leopard upgrade, the printer Samsung CLP-510 prints only if it's connected directly to my MacBook (or my PowerBook), not if it's connected via Airport (Extreme): the printers become soon busy and give the message "Device busy, please retry...", and after some time the printer print an error page with "timeout" error.
No luck resetting the Airport.
Any workaround, please?
Thanks in advance
SalvoThese steps may help:
1. Open System Preferences and click on the "Print & Fax" icon
2. Click on the "+" button to add a printer
3. Click on the "IP" button in the toolbar
4. Choose "HP Jetdirect - Socket" from the "Protocol" option menu
5. Enter the hostname or IP of the Airport base station in the "Address" field - typically 10.0.0.1 or your base station name with ".local" on the end
6. Leave the "Queue" field blank
7. Replace the auto-generated name with something meaningful to you in the "Name" field
8. Choose "Select a driver to use" from the "Print Using" option menu, and then type in the model number for your printer to locate the corresponding printer driver
9. Click "Add" to add the printer, then try printing
If you report back with your results, it would be appreciated. -
Powerbook G4 can't connect via ethernet but connects via airport
We have a small office network connected to an Efficient Networks DSL router that's managed by our isp. The router has 4 ports and a linksys 8 port switch is connected to one of those ports. Another D-Link wireless router/switch is connected to another port.
2 i-macs connect without problem via ethernet cable. They are set to DHCP and get 192.xx private addresses. Both run 10.4.5. Another older imac running 9.2.2. also has no problems.
I recently purchased a powerbook G4 and it will not connect via ethernet to the Efficient networks router. At first it was connected to the linksys, so decided to connect it direct to the Efficient Networks router. With DHCP, it acquires a 169. internet address which is self generated (i.e. no real connection). I tried to give it a static private address (talking to the isp provider). They could see the powerbook but saw all zero's (presumable mac address). By the way the Powerbook works perfectly at home connected via ethernet cable to a D-Link router connected to a cable modem so it's not a physical problem. I even checked the ethernet cable I used in the office with another computer - no problem.
When I switch to airport in the office, the powerbook connects to the network and the internet. I get some strange warning messages showing the server's and the router's private ip addresses. I click ok, and the powerbook finds an unassigned private ip address. It's the only way it will work, but it causes problems, because I can't connect to one of the network printers. Speed also isn't great.
Can anyone give me advise how to proceed. I am no expert on this stuff so keep it as simple as possible.
TksTim,
Thanks for your help. Here's what I've done before reading your e-mail. The D-Link DI-524 wireless router is connected to the Effiicent Neworks DSL router as you mentioned. One ethernet port of the EFF.Net. router is connected to the WAN port of the DI-514.
Because I have a D-Link router at home which works flawlessly with my powerbook, I decided to connect the ethernet cable of the powerbook to the D-Link which has 4 ethernet ports. Lo and behold, the powerbook acquired a private ip address and connected to the LAN and internet!
When I connected the powerbook direct to the Efficient Networks router, it could not communicate. I believe that there must be some software incompatibility between the powerbook and the Efficient Networks router. By connecting to the D-Link, the D-Link assigned an ip address to the powerbook, and it could connect to the server, lan, etc..
Only problem is that I have a Brother network printer that cannot connect to the powerbook. My powerbook cannot find it on the network. Because there is a linksys switch connected to the efficient networks router's third ethernet port, maybe as you said, going through the D-Link via DHCP (when the Linksys is also acting as a DHCP server, might cause this type of problem. What do you think?
As a final note, other imac G5's connected to the linksys switch (which then connects to the Efficient Network's router) have no problem connecting to the lan or internet and have no problem connecting to any of the printers. When I put the powerbook on that switch, I could not connect to the internet - i.e. whether connecting via the lynksys switch or direct with the efficient networks router - same results: no internet connection whether manually or via DHCP.
So the imac G5 has no problem with the efficient networks router but the powerbook G4 hits a brick wall. The G4 likes the D-Link router. I am concerned (and I will have to check this) that if I turn off the dhcp server feature from the D-Link, that whatever software issue crops up between the powerbook and the Efficient Networks router, will rise up again, because the D-Link will act like a simple switch (just like my linksys switch), and we'll be back to square zero. In any case, no harm in trying. This may be the cause of the Powerbook not seeing that Brother printer (even though it sees another printer and other macs).
Having spent hours reading about network problems, I think it's safe to say that macs have problems with certain routers. Why a G5 works and a powerbook G4 doesn't is beyond me, but clearly software must play a role. -
When iPhone 5s is connected via USB no audio is heard
Hi There -
I've seen older threads on this issue but I don't think I've really come across any solutions. My issue started yesterday; now before reading further I have to ask that you please keep in mind that I did perform the latest upgrade on my iPhone a bit earlier in the day.
When I connect my iPhone to my vehicle sync system and announce that I'd like to connect via USB, the voice recognition repeats my request and then the music on my iPhone shows to be playing on the display in my vehicle. The problem is that though the music appears to be playing and the minutes played are being displayed there is no audio coming through. When I switch to the Bluetooth Audio option all sound comes through.
Now, as a 2nd test, we connected my sons iPhone 5s via USB (he has not taken the latest update on his iPhone) and the same issue happens with his. Voice recognition changes to the USB format as requested, music appears to be playing but no audio is heard. When we change his phone to Bluetooth Audio the audio comes through nice and clear.
I'm not entirely convinced the update caused the issue so I wanted to put this out there to see if anyone has run into this and were able to actually resolve the issue.
I know the USB cable is working fine because when I do plug it into either phone the phone makes the little connection sound and pops up a brief battery percentage box. I also know the cable is working because when we announce USB as our audio of choice the system recognize USB via the iPhone.
One other thing I tried looking for was the option on the phone to switch from Docked to Synch - I know on my iPhone 4 I was able to switch back and forth through iTunes and would also have the option if I tried to watch anything via You Tube when connected to the dock; I cannot find this anywhere on the 5s when connected via USB.
Help is greatly appreciated!!!I have had similar troubles with wifi.. some improvement removing BlackBerry desktop software & drivers & reinstalling after reboot... I used the same installer I had previously, but a fresh downloaded installer couldn't hurt...
10.3.1 SW .1779 OS .2726 WLAN .1.1 Radio .2727 -
I'm running iTunes Remote App from a couple of iPhone 5's and a first generation iPod Touch. iTunes is running on a PC - Windows 7. My home network runs two Wifi Routers, each with a different SSID. I've had no problems with the Remote app running this set up for the last 8 months but recently the App can only find my iTunes library when the iPhone/iPod is connected via one specific router, when connected to the network via the other router, no iTunes library is found. I'm also running an Apple TV and it's the same as the iTunes Library, only visible via the one SSID.
Everything else seems to work fine when connected via either router, eg Internet on the iPhones (definitely via wifi)
I've tried renewing the lease on the iPhone wifi connection, restarting everything.....several times.....
It used to work fine, this only seems to have been a problem in recent weeks
Any help or advice would be much appreciated
Thanks
IanIt turned out to be the firewall settings on our router. Her machine was sending traffic that our router interpreted as a DoS attack and blacklisted her Airport's MAC address. That's why it would work fine if she switched to Ethernet.

My Canon MX 922 does not scan. My printer is connected via cable. Wireless doesn't work either.
My Canon MX 922 does not scan. My printer is connected via cable. Wireless doesn't work either. I get an error message with multiple suggestions but none of them apply to my situation.
I am so dissatisfied with this printer. I'm sorry I got it from Amazon because now it is a hassle to return it. I will never buy another Canon.
The printer menus are confusing. I hate using it. I loved my previous Canon which finally stopped working after many years, that's why I purchased a newer Canon model. Never again. Stick with cameras.
Marcy HotzThis note won't be as angry and frustrated as the last one...
Because I still had my old printer drivers and other applications on my hard drive, I think the application was trying to connect with the old printer. I deleted all the old stuff.
I also had several scanning applications on my drive which just confused me.
When I used the actual Canon MX922 application, I was able to scan but could only save as JPG, TIF or BMP (and one more, I forget which). So I did some research on the Canon site and found out how to save documents as PDF files using the Canon IJ Scan Utility.
It works now. So I'm satisfied, will keep this maching. I just had to take some time, sit down and focus on the problem. -
Internet connection via Airport Extreme/router thats not working, why?
I have been having problems with the internet connection via Airport Extreme which I find it a bit unusual and its still driving me nuts! This is what happened:
I have lost my internet connection last Sunday evening upon my return from a weekend away from home. The last time I have used the internet connection on my macbook was the previous Friday morning. Prior to the apparent disconnection on Sunday, I have always used my internet connection wirelessly through Airport Extreme (that is connected via ethernet cable to the NETGEAR DG834v2 ADSL modem which had worked beautifully until the problem arose on my return). This wireless internet connection allowed me to surf the internet anywhere in my home.
However, upon the successful re-connection to the internet via the modem router, I have discovered several new problems. I have tried to set up the internet connection wirelessly again but instead the following happened:
1. Router (Netgear) drops ADSL connection and cannot reconnect when connected to airport via Ethernet. (which is the case when using airport wireless).
2. Router connects to ADSL fine when computer is connected to it via Ethernet. (However, router disconnects when magsafe power adapter is taken out for some inexplicable reason!)
3. Router connects to ADSL fine when nothing is connected to the router (ie. No Ethernet connections)
4. Router connects to ADSL fine when connected to airport via Ethernet and computer is connected to airport via Ethernet.
So from the above, I cannot connect to the internet properly whether wirelessly or not so I suspect it could be faulty router or could it be airport extreme? I have asked my ISP for an explanation and all they have said is that it cannot be the mis-configuration but could be to do with the power adaptors or the way plugs are set up and suggested I take out all the power plugs (and power surge protector) out to switch everything off, the macbook, router, printer and airport extreme. However, when I have re-plugged them all back in, the problems I have described above still persists!
Would appreciate any help if anyone here recognises why this is the case and what seems to be the cause of this. If so, what should I do? Though I have written back to my ISP again yesterday for more help so im waiting to hear from them...
Thanks

Question regarding ONT connection via Ethernet and Cable cards
Hi,
We recently upgraded to Fios Quation 150Mbps/65 plan. We are not getting the advertised speeds (we only get like 5mbps upload) so verizon is sending a tech to switch the ONT connection from coax to ethernet.
I have 2 questions regarding this new setup:
1. If the ONT communicates with the Fios Actiontect router via ethernet instead of coax from now on, How will the set top boxes and Tivo-esque cable card powered device I currently have connected to coax, talk to the verizon system from now on, if coax is taken out of the equation? Will fios signal still flow through the internal coax wiring of the house? And moreover, I was under the impression that coax was the way set top boxes communicated and derived independent ip addresses from the Fios router, for on deman purposes and what not. How will this work from now on?
Quiestion 2.
Right next to the wall where the ONT sits, theres's a basement office where we have a PC that connects to the Fios system via an Actiontect MoCa adapter (ECB2500C) which I assume derives it internet connection from the Fios Actiontec router which sits upstairs in the living room.
Again, with the Coax about to be disabled next Friday in favor of ethernet connection from the ONT, I assume this PC will be left without internet because of the lack of internet signal in the coax? Is this correct?
Question 2.5 If my above assumption is correct, since this office is right on the other side of the wall where the ONT sits outside the house, would it be possible to run an ethernet wire through the wall that connects straight from the ONT to an ethernet switch inside the office, from which I would derive a connection for this basement PC (properly firewalled of course) and then, from said switch, continue running the ethernet wire that would ultimately reach the Actiontec Fios router upstairs from which the rest of the house derives it's internet? and would this setup affect in any way the propper functioning of the cable boxes in the house?
I'd appreciate your input and any help you can provide so I can have a ballpark idea of what to tell the Fios guy to do when he comes on Friday.
Cheers.
Solved!
Go to Solution.It's not valid to have two devices connected to the ONT, PC and VZ Router. Must be a single device. The ONT locks onto the MAC Address of the first device it sees. Since you have TV you should have the VZ router as the internet facing router.
Other options:
1. Have the VZ Router located next to the PC in the basement and then use Wireless for all other PC's.
2. Have the VZ Router located next to the PC in the basement but run one wire upstairs and connect a switch where other PCs and devices can connect via a wire.
Hope that helps.
