Tecra 8100 cannot establish a DSL connection

• 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!

• Tecra 8100: Cannot restore my OS

  I have a Toshiba tecra 8100 with the recovery of original product CD and I can not install them. When I start my computer I have to press 'C' and let go, but nothing happens. I tried several different ways to support on hold or 'C', but no result. Even when I press F2 it will not go to BIOS settings and I tried to use "del", "F1" to "F12" and several others, I took off this forum and others.

  I need a little help here? How to install win98 on this computer Moose, I already have a boot disk (floppy) but I can not install from there. The computer completely original with no changes in memory or CPU or whatever it is internal and an original drive cdrom

  Hello huh,.

  Your laptop has a functional BIOS installed, or has something happened which caused the BIOS failure?

  If none of the usual techniques for access to the BIOS work you then I can't that assume that your CMOS chip has developed a fault or there is a problem with the motherboard you.

  Can you give more information about what happens when you press the power button.

  Kind regards

• Mac cannot establish a wireless connection with printer

  I recently bought a HP ENVY 5530 printer to use in my home network. I took it successfully up to 2 Macbooks and the installer worked for about a week.  All of a sudden, no computer can connect to the printer. Laptops use OS X 10.6.8 and other 10.9.5.

  I started in case of reset problem, printing systems, repair disk permissions and then uninstalled and reinstalled the printer software. still no luck. The results of the test the State of 5530 wireless network found no problems and it is connected to the correct network. Laptops are on the correct network as well. Laptops don't seem to be able to "see" the printer.

  Where should I go from here?

  Hi @0okm ,.

  Thank you for visiting the Forums HP's Support and welcome. Thanks for the detailed information he is appreciated.

  Looks like you all did for the printer HP ENVY 5530 and your Mac to resolve wireless printing.

  Try this fix for the router, because it seems that it is the last thing to do.

  Disconnect the power supply to your router and modem and turn off your Mac
  Wait at least 45 seconds.
  Plug in the modem and wait for it to come back online.
  Plug in the router and wait for it to come back online.
  Turn on your Mac and try to install it again.

  If this does not solve your problem here is a document on setting up the printer HP with a Mac.

  Please let me know how it goes.

  Thank you.

• Why wireless adapter cannot establish an internet connection in Windows 7?

Once there is a yellow triangle with a sign of Exclamation (!) it appears on the network icon in the bar spots. And it is not connected! I tried to ping google, yahoo etc, but not a single packet is transmitted!

  Moreover, when I checked the list of devices connected in the Netgear WiFi router configuration panel, the PC was in the list, even assigned with an IP address!

  Please help someone. I need solve this ASAP. Thanks in advance.

  Control of pls with below two things...

  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.

• Bug Safari: could not establish a secure connection & search bar problem

  I'm hosting a server wiki on one of my macs and he got a self-signed certificate (the one generated by the server application). Since a few days ago (10.11.3 upgrade could be the culprit), Safari cannot establish a secure connection, no more. Oddly enough, this kind of coincide with the search box issue as well, which has been documented elsewhere.

  I checked, the certificate is marked as "always trust" in my keychain. I can access the wiki perfectly in Firefox for example.

  What a paradox, that I have to use third party software to access a software solution Apple...?

  Please let me know if you have had the same problems and if you managed to solve it.

  Thank you

  Hey! Take a look at this. This temporary has helped a number of users here. Over time, everything should be resolved then wait for a while.

  A possible solution to the problem of address bar: disable the Safari Suggestions

  If you have problems to open Web pages, take a look at these techniques proposed by Apple of troubleshooting.

  https://support.Apple.com/en-us/HT204098

  Go to the Safari menu (at the top right of your screen next to the Apple icon), choose 'Quit Safari'

  Press the "Shift" key and while holding this button on your unique keyboard, click the icon of Safari on your Dock.

  Open Safari - Preferences - Privacy - data to remove any Web site.

  Open the menu to go with the Option (Alt) key - library - key locate Safari folder and place it on your desktop. Restart your Mac, open Safari and delete the file from your desktop.

  Also, try the following steps:

  Restart your Mac.

  Try to start:

  -Stop your Mac

  -Wait until your computer turns off and after that press the power button

  -Just after you hear the startup tone, press in and hold the SHIFT key

  -Release the SHIFT key when you see a gray Apple sign and the progress under this sign bar

  -Once your Mac boot, restart dhcpd as you usually do.

• Tecra 8100, connection to the internet via a Vodafone data card

  I'm having extreme difficulties, the tecra 8100 recognizes the card etc etc, but will not let me create a profile and when I try to connect to the internet tells me that the card cannot be found... Gray goes with it - have disabled the internal modem and told my system to use the card... Help

  Hello

  Do you have software for this card? If so, you should try to re - install the software.
  But in my opinion you should contact Vodafone support because they have more experience with own products.
