• What does that mean 'APEX server has a vulnerable temporary Diffie-Hellman public key?

  Hello

  I use Oracle Cloud Services and I have already created and deployed a java (.war) via two managed servers.

  Now I use cloud services, but the concept should be the same: I would like to have access to the APEX (https://my_dbaaas_ip/apex/pdb1/), but I get the following security message:

  «The server has vulnerable temporary public Diffie-Hellman key...» »

  I also checked to calculate Service (network, safety rules) and port 443 is open and I also created a tunnel via ssh...

  Someone had the same warnng to access the APEX to develop the java application?

  Thank you very much

  I think it's a problem of security defined by the Chrome browser...

  Now only accessed via a different browser and it worked!

• Server has a weak and ephemeral Diffie-Hellman public key

  Seems 45 Chrome and Firefox 40 block ciphers DHE

  Today, we get the following errors when you browse the vRO Web Interface (and the Configuration interface)

  Tested with the device of the two vRO 6.0.1 and 6.0.2 versions

  Everyone knows this?  And is there no work around better than using the '-cipher-suite-blacklist = "parameter in Chrome?

  I have raised a support ticket with VMware, but thought it would be an idea to post here as well.

  Chrome:

  

  Server has a weak and ephemeral Diffie-Hellman public key

  ERR_SSL_WEAK_SERVER_EPHEMERAL_DH_KEY

  Hide details

  This error can occur when you connect to a secure (HTTPS) server. This means that the server tries to establish a secure connection, but because of a disastrous misconfiguration, the connection would be not sure at all!

  In this case, the server must be fixed. Google Chrome will not use unsecured connections to protect your privacy.

  Learn more about this problem.

  Firefox:

  

  The secure connection failed

  An error occurred during a connection to vro-device - hostname:8283. SSL has received a low ephemeral Diffie-Hellman key in the handshake message exchange the server key. (Error code: ssl_error_weak_server_ephemeral_dh_key)

  The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

  Contact the web site owners to inform them of this problem.

  You can try to change the two server.xml file in: / etc/vco/app-server and/etc/vco/configuration in the update of the file server.xml "ciphers" attribute by removing TLS_DHE_... ciphers. Then, restart the vco-server, vco-configuration services server vco and vco-configuration services

• low key public ephemeral Diffie-Hellman in vCenter Assistant support 6.0.0.0 Build 2632669

  I have install the vCenter Assistant support, no problem. But when I used Chrome (v47) to access it, I had a small "Ephemeral DH public key" error I tried to give him a certificate signed by our Windows 2008 R2 Enterprise internal CA, but not joy. IE will not work, but Chrome. What can I do to get rid of this error blocking (in addition to switch to IE, which is not a good solution)? I saw a note to update some files server.xml in VCOrchestrator to the same question, but I can't find a comparable file on the device to support Asst. As far as I can tell, our CA used a model that uses the Microsoft Enhanced RSA and AES Cryptographic Provider, sha256, 2048-bit keys - what is weak on this subject? What did I miss?

  Someone at - it ideas?

  I would love to see a response from the support, but I think that the only option is to wait for an update of the device.  I did a little research and it looks like a problem with the OpenSSL version delivered with SLES 11.  OpenSSL v0.9.8 does not support TLS 1.1 or 1.2 (TLS 1.2 - SUSA Blog |) The communities of SUSE) and there is no simple mechanism was updated to the version within the unit. No matter what kind of cert you put on the system, he will always support the resulting weak encryption methods Chrome report the site.  I tried to limit the list of encryption algorithms to only ECDHE, but Chrome still did not like it.

• not checking ephemeral Diffie-Hellman key to CAUSE low mail SSL

  Nice day

  I made an update of mozilla any last night and for some reason, thunderbird will not send email from 2 of my accounts that are located on the same server. He tells me that it is connected to this server, but never offers anything from him. It worked well until this recent update that was made. Any help is appreciated.

  The error means that your e-mail provider's server is not properly configured and exposes you to the attack of the impasse. Thunderbird strives to prevent this.
  https://weakdh.org/

  To work around the problem, you can install this add-on.
  https://addons.Mozilla.org/en-us/Firefox/addon/disable-DHE/

  Note, this will allow you to connect to the server in a secure way, but there isn't the underlying problem of the server is still vulnerable.

  See this article if you have problems to install the add-on for Thunderbird.

• 38.1.0, getting new mail is no longer works. Bug CAUSE deadlock/weak Diffie-Hellman for key 1185060 SOLUTION mitigation requires the TLS/SSL security key length > = 1024

  That's about all. After the upgrade, I can no longer receive mail. I can send, but it does not put a copy in the "sent" folder and I get an error.

  "There was an error saving message in sent. Try again? »

  But the message on the other end.

  I checked the same email on my phone and Webmail accounts. No problem.

  I deleted the account and tried to add it back, but get an error:

  "Invalid username or password"
  "Setup could not be verified - is the name of user or wrong password?

  The user name and password are correct. Yet once, nothing changed with the account mail and it market in Webmail and on my iPhone.

  Any help would be greatly appreciated!

  Same problem here. In my case, I control the server. So I had my software update server admins and install a 2048-bit key instead of the old key of 768 bits. (By the way, for those who have their own server faced with this problem, you must switch to cPanel/WHM 11.5 to be able to upgrade the key. Older versions store more 768 bit keys for SSH.)

  Now, most of my accounts work. However, one account is always the error.

  When I check the error console, I find the following:

  Timestamp: 22/07/2015 08:44:35
  Error: An error occurred during a connection to [domain]: 143.

  Cannot communicate securely with counterpart: no common encryption algorithm.

  Hi all

  Can I confirm with expert from Microsoft, it's windows foundation server 2012 may not be the first domain controller (which means that the first AD in the forest)? It must be attached to the root of the forest as a domain controller.

• Problems sending/receiving mail - error number: 0x800CCC0E - "the connection to the server has failed..." »

  De : Briangie

  I've been out of town for a few days. I was using a public Wi - Fi connection to my laptop. The first part of the week worked fine, but now using the same wireless connection, I receive the following error message. Has happened since yesterday afternoon 03/10/08 and today is 05/10/08. What is the problem? Help, please!

  The connection to the server has failed. Account: 'mail.charter.net', server: 'mail.charter.net', Protocol: POP3, Port: 995, secure (SSL): Yes, Socket error: 10060, error number: 0x800CCC0E

  From: Gary van

  In Windows Mail, go to the tolls, accounts, select the account mail.charter.net, properties, advanced. Change the port number for the incoming (POP3) server from 995 to 110. Make sure that the adjacent SSL option is not checked. Click OK.

  As a general rule, the owner of the SMTP server must be the same that provides your Internet connection at the moment.

  The workarounds available when sending abroad are the following:

  1. use webmail to send (via your browser).
  2. ask your ISP if they have one port other than '25' for SMTP. I do not think that
  Charter of fact. Cable companies are very difficult to accommodate travellers.
  3. If you frequently use the same connection away from home, replace the SMTP Protocol
  Server in this respect. It's a little tricky, but if you want to go this route.
  I can provide more details.
  4. If you frequently send to multiple locations, get a free Gmail account,
  Configure it to POP access and use for your shipment of household chores.
  Gmail uses port 465 for SMTP, which is not blocked as is port 25.

• vulnerability of Diffie-Hellman < 1024 Bits (dead end) on the VPN

  Hello world

  Scans of external provider shows a vulnerability for Diffie-Hellman< 1024="" bits="" (logjam)="" on="" the="" vpn ="" on="" our="" cisco="" asa="" running="">

  No idea how can I fix on Cisco ASA 5520?

  Concerning

  Mahesh

  IT depends on how the analysis was done. If only they check your turned to the public outside the address and then only having do not SSL services on it will make the vulnerability "disappear".

  If you need the service out of all interfaces, you need to upgrade so that the SSL services are patches they are seen on any interface.

  Or you could simply not patch and accept the risk.

• The OCSP server has no status for the certificate

  From just today, whenever I try to access www.fanfiction.net, I get this error message from FF: -.

  "Secure connection failed".
  An error occurred during a connection at www.fanfiction.net. The OCSP server has no status for the certificate. (Error code: sec_error_ocsp_unknown_cert) "

  I already tried removing the Cert8.db and Secmod.db and uncheck only the two OCSP parameters d ' option in advance. Neither work. The site is accessible to any other browser so it's really Firefox question.

  Need advice on how to fix this ASAP.

  the issue seems to have been fixed by the site already, you can go ahead and give security.ssl.enable_ocsp_stapling to true.

• X3650M5 does support stop automatically if this server has worked in the temperature of overheating?

  X3650M5 does support stop automatically if this server has worked in the temperature of overheating?

  Hello
  Basically, Yes to your question.

  For more details;

  IMM2 Web GUI access via browser and see environmental specifications tab in the server properties menu.
  There are two types of threshold, "Higher criticism" and "upper Fatal".

  If goes on "Higher criticism", then a soft stop will be initiated, where the next depends on your operating system of his behavior causing shutdown graceful or not progressive.
  If more higher jumps "Upper Fatal", then a hard stop will be engaged, which is not a normal shutdown of the typical operating system perspective.

  Kind regards

• HEX 0x8BBB0011 as the connection to the server has been disconnected

  Hello

  I use a shared variable of the network to control a loop in FPGA in cRIO 9073. 1 for a month, the program was runing without any problem, but suddenly, the VI is thrwoing an error

  "HEX 0x8BBB0011 connection to the server has been disconnected.

  The error or warning occureed while writing the following shared variable

  \\NW-cRio\NW Library\NW_Force_cal

  \\169.254.106.130\NW Library\NW_Force_cal ".

  A screenshot of VI is fixed, the NW_Force_cal is highlighted.

  After the VI has been shut down and restart the VI took over running without problems. This kind of unpredictable behavior is very difficult to manage, I lost data in real time during 12 hours of recording because of this problem.

  Please suggest a solution for this problem.

  Thank you

  The error has explained the issue.  The network had problems that led to the server being offline.  How to solve this problem is to understand what is meant by "real time".  It's just another way to describe a deterministic calculation.  In other words, the program ensures that everything will happen within a predetermined period.  Order things to be deterministic, they must be controllable.  The most obvious way to break the determinism is to prompt the user for entry.  As we cannot guarantee clearly not the user will respond within a given period, can no longer call the deterministic program.  In this case, we have a more subtle break of determinism.  Relying only on a network will break determinism.  It is not simply a way to ensure that the network is not getting hit harder than usual.  In this case, the network was down for a period of time long enough to raise an error.

  Here's where we get to fix things.  Once the error has been generated, the code to do with it?  The wire of the error is not used for anything else.  I expect to raise an error and stop the program.  Clearly this isn't the desired behavior.  So, why we do not use the wire for an error handling?  In case of error, you can connect the data locally.  When you cover the network, you can clear the log to the host PC that you usually use to collect your data.  This command removes the dependency of your network for the code works.  With the help of a more robust code solves the problem with the relatively easy error management.  Unfortunately, there is absolutely nothing anyone here can do to ensure your network never loses connectivity.
