Impossible to establish a network connection on PC

• Questions of ESXi 5.1 ISCSI--> cannot establish a network connection (continued)

  Hello world

  I had a problem there not too long ago (thread link below) where my ESXi hosts could not establish a connection with an IBM DS3500 on start up and "rescan", however their connectivity worked correctly without any problem after commissioning and when a "rescan" finished. We determined that the most likely cause was the unit IBM itself. However, I wasn't completely satisfied.

  In order to deepen the question and dismiss my guests being the problem, I created a unit ISCSI myself with two new hosts of ESXi 5.1 (version 1157734).

  ESXi signals that it cannot connect to the initiator ISCSI (network error) - but it can run virtual machines and browse data stores?

  The configuration is the following:

  Test environment:

  2 x ESXi 1157734 hosts

  1 x server Freenas ISCSI (ZFS R10)

  At the start of my ESXi hosts in the test environment, download the same error as our production environment. They also put on the same error message (in the event log) when I "rescan" map of the ISCSI software. However, once the scan is finished, I can't see any error message and everything continues as it should (Round robin, active active). I can get a brilliant flow also. It's as if the errors are almost... false positives?

  Example of the error message (test environment):

  Connection to the iSCSI target

  IQN.2011 - 03.org.example.istgt:iscsi on vmhba35

  @ vmk2 has failed. The iSCSI initiator couldn't

  establish a network connection to the target.

  error

  ESXi hosts are configured as follows:

  Test environment:

  • (ESXi hosts) Two network cards for ISCSI, one for VM traffic
    • NIC1: 10.20.20.2/24, NIC2: 10.30.30.2/24
  • (Freenas) Two network cards installed on the ISCSI device (dedicated to ISCSI traffic)
    • NIC1: 10.20.20.1/24, NIC2: 10.30.30.1/24
  • ESXi is set to round robin, which works properly (I can max on both ports at the same time)
  • Two VMKs are related to the ISCSI Software initiator and defined to dynamically discover the two ISCSI addresses
  • Unity of ISCSI and the hosts are not on the VLAN, the switch is dedicated to ISCSI traffic (However in the production, the two networks are separated by VLAN.) I removed the in the test environment to simplify everything)
  • The vSwitches (who hold a single VMK for ISCSI) are fixed:
    • "Promiscuous" mode: reject
    • Change of MAC address: accept
    • Forged passes: accept
    • The traffic shaping: disabled
    • No NIC teaming (obviously)
    • Each VMK inherits the settings of these

  Quick points:

  • My hosts use VMware approved NIC in my test environment. My production environment runs on full VMware hardware approved
  • Can I use ping of vmk join each each VMK ISCSI initiator
  • I can use the nc-z target_ip 3260 command to check connectivity to the port
  • The ISCSI test has two network adapters, each on 1 Gbps ports
    • I can get around 800mbps per port when copying lots of files (both ports are active)
    • I see no error in copying a large number of virtual machines around, or backup files
  • I only see errors on start up and "rescan".
  • I have two network adapters on each host ESXi dedicated for ISCSI. Each NETWORK card has a single VMK. A single mapped port on ISCSI, the other is mapped to port B (I used to have two VMKs by nic, but I removed that in order to simplify everything)
  • I have updated the firmware on our switch of production. No results
  • I've used 4 different switches in order to avoid a network problem. No results
  • I tested ESXi versions 5.0, 5.1 (799733 & 1157734), all have the same mistakes
  • The ISCSI ports are on different networks according to the VMware (I was told not to put on the same network VMKs)

  Any ideas? It's starting to drive me up the wall. Any help would be greatly appreciated

  I've seen several times in recent months and was beginning to think it is specific to the HP P2000 units because it's the only time wherever I saw him! I now believe that ESX/iSCSI rather than issues of driver or table.

  On my last install, I found that errors occur as soon as the table is connected, i.e. before any storage is displayed.

  Single host ESX, no guests. 2 Intel adapters to 2 HP past by dedicated HP P2000 1 GB table with all 8 wired ports.

  All roads are good, all lights are in the State expected.

  It did not affect the use of the storage in question to any site, so there has been no need / a momentum of any further investigation.

  B! 886y annoying however!

• OfficeJet Pro 8710: Impossible to establish the wireless connection between my laptop and OfficeJet Pro 8710

  I'm tryng to connect wirelessly between my laptop and printer but I am unable to do so.

  My laptop finds the printer and when I go to add the device I invite me to "Enter the WPS PIN code for your printer". So, I printed out the Configuration Page of the network and it gives me the "wi - fi direct password", which I suppose is the password that is required to establish that it connection (I may be wrong in my explanation). However, when I type the password on my laptop it does not establish the connection. I said "try to add the printer again, or check with the manufacturer for addiitonal installation instructions.

  Any insght and assistance is greatly appreciated.

  Thank you.

  Hello

  You should searh for your wifi network at home and connect your printer and the laptop to the network. Direct WiFi option is really only for configurations that do not have a modem/router.

  You may need to disable the option Wireless directly on your printer to help the wireless configuration.

• Impossible to establish a VPN connection with a router configured as a Cisco server using client VPN 5.0.00.0340

  Hei guys,.

  Please help me on this one because I'm stuck enough on her...

  I am trying to connect to a Cisco 3700 router configured as a VPN server by using a VPN client and the VPN connection does not settle.

  This is an extract from the log:

  130 12:48:30.585 07/01/11 Sev = Info/5 IKE / 0 x 63000001

  SEND to > ISAKMP OAK INFO (NOTIFY: INVALID_HASH_INFO) for 200.100.50.173

  I enclose the whole journal extract... The message "BOLD" is quite obvious, you mean, but I'm 100% sure, in the login entry, I typed correctly the group password: pass

  My topology is very basic, as I am setting this up only to get a clue of the operation of the Cisco VPN. It is built in GNS3:
  -2 3700 routers: one of them holds the configuration of the VPN server and the other would be the ISP through which the remote worker would try to establish a VPN connection. I am also attaching the configuration file for the router configured as a VPN router.

  Behind the second router there is a virtual XP machine on which I have installed VPN client...

  My connection entry in the customer is to have the following parameters:
  Host: 200.100.50.173 , //which is the IP address of the VPNServer
  Authentication-> authentication-> name group: grup1 password: pass / / I'm quite positive that I typed the correct password... even if the log messages are linked to a misidentification.

  I use public addresses only, because I noticed there is a question about behind the NAT VPN connections and is not not very familiar to the NAT.

  Another aspect which can be of any importance is that "allow Tunneling of Transport" in the tab Transport to the input connection is disabled

  and the VPNServer router logs the following error message when you try to establish the connection:

  * 01:08:47.147 Mar 1: % CRYPTO-6-IKMP_NOT_ENCRYPTED: IKE 200.100.50.34 package was not encrypted and it should have been.
  * 01:08:47.151 Mar 1: % CRYPTO-6-IKMP_NOT_ENCRYPTED: IKE 200.100.50.34 package was not encrypted and it should have been.
  

  You have no idea why I can't connect? Y at - it something wrong with my configuration of VPN server... or with the connection entry in the VPN client?

  Thank you

  Iulia

  Depending on the configuration of the router, the group name is grup1 and the password is baby.

  You also lack the ipsec processing game that you would need to apply to the dynamic map.

  Here is an example configuration for your reference:

  Hope that helps.

• Problem to install Oracle 11 g - impossible to establish a remote connection

  In short:

  I just installed Oracle 11 g and created a data base and the headset, but I'm unable to connect remotely with a customer database.

  My environment:

  Oracle 11g is installed on a VirtualBox (4.3.18) Red Hat Linux 6.5 VM.  The host operating system is Mac OS X Yosemite.  Linux VM is assigned a static ip address and the host and vm have host entries to resolve this name server:

  192.168.58.152 rhel65opdev-vm

  I am able to ping rhel65opdev-vm from these two places.

  Host: 64 bytes from 192.168.58.152: icmp_seq = 0 ttl = 64 time = 0,287 ms

  VM: 64 bytes of rhel65opdev-vm (192.168.58.152): icmp_seq = 1 ttl = 64 time = 0.027 ms

  I am also able to ssh into the Linux vm without problem.  If I try to telnet to the virtual machine on the port of configured database:

  = > telnet rhel65opdev-vm 1521
  192.168.58.152 by train...
  Telnet: connect to address 192.168.58.152: connection refused

  I have another Red Hat 6.5 virtual VM from where I'm modeling this new machine, which has the same version of Oracle on it, installed and working (which I myself installed without problem, but a long time ago).  I am able to connect remotely to this base since my Mac using Toad and SQLDeveloper without problem and I can telnet to port of database and there is no problem.

• Impossible to establish a wireless connection on the Satellite

  Hi all

  I am desperate because I implemented an env wireless in my house, and all my machines work fine except the toshiba one.

  In fact I see the network wireless only in Intel tools, then I click the button connect and get connected a second and the GET disconnected (but wireless is always visible from the laptop.

  Where do you think the problem?
  Router wireless card or the problem is in the toshiba.

  Note that I'm able to make the system operational wireless on another without any problem.

  Thank you for your quick feedback on this issue.
  Best regards.

  Hello

  Not easy to say what could be wrong or what might help.
  You must see this:

  -> try to update the WLan card driver
  -> check the WLan card driver and advanced properties tab more you could disable option economic power.
  -> try to use own windows Wlan connectivity
  -> disable the encryption on the router and try to connect without any security option.

  I found the problem (s), even if I am always left with a few questions.

  During this process, I have disabled the firewall, but that did not help. However, I noticed 'tweaks' accessed via the tab 'Advanced' in 'Microsoft Firewall' which looked like, they must be checked in order to access the internet. I checked these and reintroduced the firewall. After I got things working, I unchecked them and things still worked so I obviously don't understand what these parameters.

  The solution:

  (1) I have to go straight from the modem cable to the computer. I can't have a cable modem, router wireless, computer, even if using hard wire, and even if this same configuration works with another computer. Also, I can't use a cable length to go from modem to the computer. So, it seems to have had a problem of cable length. Power problem? Only connected to this computer devices are the mouse, the keyboard and the Ethernet. Would not this be fixed with an upgrade of the power supply? Or is it due to the quality of the Ethernet hardware on the motherboard? It's a Dell Vostro 200.

  (2) in back and forth between configurations while following the problem, you must think to unplug the modem to reset between each configuration. You may have stumbled upon the solution, otherwise he's not shot. Also, I unplugged the cable from the modem when you reset data cable - do not know if it was necessary. I wanted to limit the degrees of freedom that I had a lot, as it was.

  I can establish an internet connection via internet explore using a router at home, but whenever I try to connect using firefox, it said that it is impossible to connect.

  One possible cause is security software (firewall) that blocks or limits Firefox without you informing on this subject, possibly after the detection of changes (update) for the Firefox program.

• Impossible to activate the laptop on Windows 7 computer wireless network connection

  I'm not able to activate my wireless network on Windows 7 laptop connection. I have Atheros AR928X Wireless Network Adapter and I am unable to connect wireless. I was able to connect a few weeks previously, but now my Wireless Network Connection is still "NOT CONNECTED", I called my local router support and they said that everything is good on both sides and that my settings of the adapter or the driver must be on off somehwere. Help!
