I tried to find a lot (I've already spent one complete day on this) to find the reason for following error:
000004DC: LdapErr: DSID-0C0906E8, comment: In order to perform this
operation a successful bind must be completed on the connection., data
0, v1db1
I've windows AD setup as LDAP server and using this for authentication in sftp using proftpd+ldap in Linux machines.
I've two machines (machine#1 and machine#2), where proftpd+ldap is configured. In both the machines all the required configuration (such as proftpd.conf and ldap.conf) is exactly same.
However, when I try to sftp to machine#1, it is able to do it successfully and shows no error in wireshark (tcpdump). However, when I try to sftp to machine#2, it gives me following error. Below is the tcpdump collected from LDAP server.
What I am unable to figure out is, why in failure case (machine#2) only, I am seeing bindRequest "<ROOT>" simple but not in successful case (machine#1).
There is clear indication that there is something in client (machine#2), which is causing this, but not able to figure out what?
Help will be highly appreciated.

Facing error 1067 for when trying to deliver into integration stream.
On investigation, it was found that albd service isn't coming up.
Have checked out the doc regarding this error code on IBM, none of the resolutions have helped.
What could be the possible cause?
Errors faced :
cleartool: Error: Unable to contact albd_server on host 'hostname'
albd_contact call failed: RPC: Unable to receive; errno = [WINSOCK]
Connection reset by peer
I have seen this when the ClearCase license server itself was down.
But if this is not the case here, check the Windows Event viewer for more clues on that particular instance, for example right after attempting to start the albd service.
I don't know if that is the local host or a remote one. If the local host, this technote may help: https://www.ibm.com/support/pages/troubleshooting-albd-startup-failures-microsoft-windows
If a remote host, that technote may still apply, but you may also be dealing with a network issue. Some questions may help clarify the issue in that case:
Does the issue impact multiple clients?
When did this start?
Are there any functions that work from this host? ("Cleartool quit" command, cleartool lsvob, etc.)
I'm trying to run the azure iothub sdk c sample of the mqtt protocol.
I've compiled hte project but when I run the program it returns some error about SSL routines
This i the complete error:
error:1416F086: SSL routines:tls_process_server_certificate:certificate verify failed
Info: Closing tlsio from a state other than TLSIO_STATE_EXT_OPEN or TLSIO_STATE_EXT_ERROR
I got only this error repeated five times, one for each accepted message ready to be transmitted to the IoTHub.
I've read that I need to set trust to the openssl certs in the sample directory but I've not figured out how to do this task or how to avoid this problem.
Is there someone who has already faced this issue?
This document describes in detail how to prepare your development environment as well as how to run the samples on Linux, Windows or other platforms. Please refer to the section to rebuild you code and then run to test.
Try using the TrustedCerts option. With this option you can pass to the SDK the certificate that is used to validate the server's certificate. This is typically used when either you don't have the root certificate, Baltimore CyberTrust, or your device does not have the concept of a trusted root certificate store. You can find an example of this option being used in

I'm facing trouble using parse4cn1 because apparently I have a connection issue with the server(back4app). I was working with parse4cn1 for quite some time and everything went fine until yesterday. Right now I am getting a ParseException when using it -
[parse4cn1] Request failed.
ParseException [code=100, msg=Connection to backend failed., cause=null]
**The project runs perfectly on a different pc. tried to use another network on this computer and still get the same connection issue.
It must be my computer blocking me from using this particular server. unfortunately I do not know how to check if this is true and obviously how to fix it..(am using netbeans if it matters..)
help would be apreciated!

Eventually the issue was in my codename1 simulator, apparently the default behavior of it is blocking all outgoing network connections (or at least that how it was for me). I had to simply change it to regular network activity.
We've just updated Nagios from 3.5.x to the current version (4.0.7) and subsequently added a new host for monitoring.
The new host shows as 'Down' in Nagios, and this seems to be related to the fact that pnp4nagios is not logging performance data (the individual checks for users, http etc are all find).
Initially there was an error that the directory
/usr/local/pnp4nagios/var/perfdata/newhost.com
that contains the xml setup and rrd files for the new host was missing), so I manually created this directory, but now it complains that the files are missing.
Does anyone know the appropriate steps to overcome this issue?
Thanks,
Toby
PS I'd tag this 'pnp4nagios', but that tag doesn't exist and I can't create them
UPDATE
It's possible that pnp4nagios is a red herring/symptom. Looking more closely I realise that Nagios actually believes the host is down, even though all services are up. The host status information is '(Host check timed out after 30.01 seconds)'...does this make any more sense?
It's indeed very unlikely that pnp4nagios has something to do with your host being down. pnp actually exports output and performance data to feed the rrd database and xml files (via npcd module or evenhandler command).
The fact that nagios reports the host check timed out after 30 sec means that :
- you have a problem with your host check command, please double-check the syntax
- this check command times out after a certain timelapse (most likely defined in nagios.conf) because the plugin was still running.
I'd recommend running this command from the server's prompt. You want to do something like :
/path/to/libexec/check_command -H ipaddress -args
For example:
/usr/local/libexec/nagios/check_ping -H 192.168.1.1 -w 200,40% -c 500,80% -timeout 120
See if something might be hanging. Having the output would be helpful.
Once your host check returns correct output and performance data to nagios, pnp will hopefuly do the rest.
In the unlikely event it helps anyone, pnp4nagios was indeed a red herring. The problem was that ping wasn't enabled for the host being checked, and this is the test for whether a host is up or not. Hence this was failing, despite other services being reported as working.

I'm trying to connect to a database using SQLDeveloper and I get the following error:
An Error was Encountered performing The requested operation:
IO Error: Conection reset
Vendor code 17002.
Could you please help me?
Listed are the steps that could rectify the error:
Press Windows+R
Type services.msc and strike Enter
Find all services starting with ora start these services and wait!!
When your server specific service is initialized (in my case it was orcl)
Now run mysql or whatever you are using and start coding.P
I encountered same problem with ORACLE 11G express on Windows.
After a long time waiting I got the same error message.
My solution is to make sure the hostname in tnsnames.ora (usually it's not "localhost") and the default hostname in sql developer(usually it's "localhost") same. You can either do this by changing it in the tnsnames.ora, or filling up the same in the sql developer.
Oh, of course you need to reboot all the oracle services (just to be safe).
Hope it helps.
I came across the similar problem again on another machine, but this time above solution doesn't work.
After some trying, I found restarting all the oracle related services can fix the problem. Originally when the installation is done, connection can be made. Somehow after several reboot of computer, there is problem.
I change all the oracle services with start time as auto. And once I could not connect, I restart them all over again (the core service should be restarted at last order), and works fine.
Some article says it might be due to the MTS problem. Microsoft's problem. Maybe!
I had the same Problem. I had start my Oracle TNS Listener, then it works normally again.
See LISTENER: TNS-12545 ... No such file or directory.
In your case the "Vendor code 17002" is the equivalent of the ORA-12541 error: It's most likely that your listener is down, or has an improper port or service name. From the docs:
ORA-12541: TNS no listener
Cause: Listener for the source repository has not been started.
Action: Start the Listener on the machine where the source repository resides.
