• Then and coming great network engineer...

  What's up guys...

  I was hoping you guys could help out me. We had a team of engineers that all leave the company in a position against management. Now I have been launched or promoted in the role of administrator/network engineer. I'm really looking forward to the challenge and am very happy for the opportunity. I've done some self-training and I recently got my CCNA and CCGD and currently my CCNP.

  My question is this... I want to make my own; the network and what I mean by that is, I want to change our routers and switches for maximum optimization of our network devices.

  Can someone tell me what type of daily maintenance checks should I do on a daily basis to ensure that our network is running optimal?

  We also lack EIGRP as our IGP and a MPLS on the WAN network. What can I check to make sure that all circuits give us all the bandwidth?

  In addition, I'm not very familiar with the Cisco ASA; How will I know that it works? What should I look for?

  Thanks in advance...

  I would recommend a good book for you: "The practice of system and Network Administration" by Leduc, Hogan and Chalup. It is full of good framework type of information which is not specific to the provider.

  In addition, I would say in general:

  1. document your network - physical and logical (Layer 2 and layer 3).

  2. know each configuration file and mean it of all lines. Save them! (RANCE is a tool free and open source.)

  3. base your performance (i.e. WAN links and use uplink switch) with a basic snmp monitoring tool. (CACTUS is a good OpenSource tool.)

  4 send your syslogs to a central tool and know what they tell you - looking messages feel and change any anomaly. On the ASA set your recording to not exceeding level 4 or 5 - level 6 (information) you will tell each connection and tcp udp only and should not be used during troubleshooting. Even if you can not read and understand each syslog at least know the typical daily volume. If typical for your network is 1000 messages a day and then one morning your 5000 find you will probably have to fix something (if your phone is not already ring). (Kiwi tool - paid version a bit more pleasant but free is available too).

  Finally... NEVER stop learning. I did this for more than 30 years and almost a day happens that I don't learn something new. Good luck!

• Slow network preferences

  Hello

  For some reason any, whenever I click on the icon WiFi at the top right that it takes a good 2-3 seconds for the menu to appear which shows the currently connected network, etc... and then when I select "Open Network Preferences" on the bottom of this menu it takes forever for interfaces to appear. For 20-30 seconds, it appears as below:

  

  Finally, all interfaces appear but it is really slow to change any settings here. It's the same if I go into the system preferences-> network. All other components are preferably fast and the rest of the operating system is fast and behave normally. It started when I upgraded to 10.11.5.

  This is what appears in the console until the interfaces to load:

  

  Network engineer, it makes me a little crazy.

  Any suggestions?

  Go to System Preferences > network > open the lock by entering the username and password > click on the gear icon > choose make active service > set the order of service

• Quick and dirty network

  I need to be able to quickly set up a network in a box of 3.5u4 ESX. The purpose of this network is to deploy a test domain. Of course, I want to make sure that the network traffic do not escape and cause problems with production systems. To do this, I created a new switch without a vmnic which are entrusted and labeled "Test VLAN. I then upgraded to the top a workstation and a windows Server 2003 and placed the two virtual machines on this newly created network. The problem is, the machine of the workstation (windows xp sp 3) sees the area windows server, but the area of windows server can not see the virtual machine from windows xp. Someone has suggestions or maybe a better way to get the same results? The network engineer is against the creation of an another VIRTUAL switch side LAN network/physical, that's why I'm trying to do it from the side ESX. Thanks in advance.

  If the XP machine can ping the server, then nothing is wrong at the networking level as the package on the server AND RETURN.  If the server cannot ping the XP machine then its something on XP don't act don't not ICMP traffic.  When you look at Windows 2003 can you manage the desktop by using computer management or map to the share admin$.

  Can the XP ping localhost box and card to himself?

  I saw this usually when there was something wrong with the network adapter or driver of filter level like Norton internet security or bullshit has installed and removed.

• which computer to buy

  I am trying to decide between the macbook and the macbook pro.  How single jack it works with a hub?  I'm keeping my computers for a long time.

  Hello

  I offer this with the small MacBook, Air and retina 15 between work and family.

  Single port USB - C works well for me. It was purchased with the understanding that my MacBook is an ultra light laptop computer machine and isn't the big complete system the retina 15 ". Wearing a prevent me from any generally required functionality which currently includes a network engineer who uses the port for console series Ethernet and 9600 baud connections.

  The big 15 MacBook is not unlike several 13 years I bought for my users. The two USB ports, and Thunderbolt will allow you to do more with the devices.

  Go to a store for all compare and manage them. Look at the resolution of the screen, compare them physically. There is no right or wrong. My two's ultimate portable computer choices. One is good to be light and a load of long battery life. The other is beautiful to be incredibly powerful, more flexible, and more pleasant for a long session with the keyboard and screen. The number 13 "retina Air models and that I bought for my users to adjust between the two that I use available at the best price.

  I do not know what hub you will use, but so far the USB - C has worked well for me. I use it with an adaptor series and Ethernet adapt otherwise a VGA display.

• HP Deskjet 3055 A does not connect to the WIFI with security

  I'm trying to configure a Deskjet 3055 A on my DD - WRT router.  I am a highly qualified network engineer, so I don't know 100% what I'm doing.

  First, DD - WRT supports WPS connection, because these are very precarious.  This means that my only way to connect the pritner to my home network is to connect to my PC and use the Setup utility (downloaded from your page drivers) I use the 28.8 version.

  My router supports the 2.4 and 5 GHz and I know the printer is only 2.4 GHz.  I disabled completely the 5 GHz network in order to connect the printer, even though it shouldn't have any effect.

  I restarted my router and reset the printers wireless network using its integrated control panel.

  In any case, after a shameful 2 hours troubleshooting, I did discover that the printer WILL NOT CONNECT to the WIFI network if any security is applied against it.  It works 100% fine with open security however, it is totally unacceptable.

  I tried both WPA Personal and WPA2 Personal, both with the same effect.

  For reasons to try, I added also the printer to my network WIFI open and tried to manually change the setting WIFI via webinterface of printers, however, whenever I try and access the wireless configuration wizard, I simply get an error message saying "Internal system error" - eventually I managed to work around this another bug that has been there for years (see http://h30434.www3.hp.com/t5/Printer-Networking-and-Wireless/Internal-System-Error-prevents-access-t...

  After installing printers web interface WIFI, the problem is always the same and it does not connect.

  HP, we were in the order of 2500 of these printers for users of our remote site.  If you don't come to the top with a quick solution/bug fixed, consider the lost business!

  Concerning

  Ian

  After playing well, I managed to find a solution for this!

  For all users who are unable to find a solution by using the other methods, here's what to do.

  Change your local network to open the safe but note your WIFI settings for your default installation.

  Connect the printer to the open network the HP software (via USB cable)

  Go to the URL of the printer, but make sure that you connect through HTTPS - if you get an internal system error, keep refreshing until it works (WHAT A JOKE!)

  Click on 'Network', then click 'Advanced' on the left.

  Enter the network settings as they need to be secured.

  Downstairs, check "in an infrastructure network, use 802. 11b / g behavior (assuming that your assisted supports g, otherwise use the b only option), then click on apply.

  Turn on your wireless security, on your router and then the printer should connect!

  I am really confused as to why this is not automatically enabled, if the printer is not working with security on a Wireless N network wireless, then have this as the default!

  HP - feel free to thank me in this post!

• You print envelopes with HP LaserJet CP1525nw color

  I tried to print envelopes on our printer above.  My document is in Word is formatted accordingly for a #10 business envelope

  Under the terms of the HP help function, I found the info on how to set up my document print options, then it would print correctly.

  The first envelope printed on the side of Rabat; I have reloaded in Tray 1 and was ready.

  The second envelope printed with success so I thought that I understood.  So, I loaded the tray paper with 5 envelopes, hoping to print them massively.  I couldn't get it work when I tried to print 4 at a time.  I got a "Paper jam in tray 2" error and I was not yet using tray 2.  I erased the 'problem' and AN envelope printed with success, then I got the same error message.

  I had 2 envelopes more printed this way, but every time I got the same error message, erasing the machine and 1 printed envelope.

  Frustrated, I cancelled the multiple print job and tried to print envelopes one by one.  Now it does not at all even if I delete the phantom paper jam every time.

  Can anyone help with this?  It makes me nutty.

  Background info: my husband (network engineer) install the printer.  I have over 20 years of experience in processing and usually have good results with appearing on printing problems.  It left me speechless!

  Thanks for any help you can provide.

  Dianne

  The CP1525 allows you to print envelopes. There are two ferries, which can be used. I will describe using only the lower tray. Normally, this tray is used for standard paper.  To use the letter envelopes, you must remove the tray and then make some changes. Remove all paper. There are supporters of blue color paper. Two are used for the width of paper. Move the cursor to the Center so that it will load the envelope with the top to the left. Put the envelope with the printable side upward and the top to the left. Slide the blue paper holders so that they touch the top and bottom. Then push the envelope completely backwards and then move the holder unique blue paper in the front to make it against the envelope. You're ready to print as much as the printer.

  I select the printer properties. I indicate that I am printing an envelope. I had also to indicate the landscape. I also had to move the appropriate print areas where I want to be. Then I added my address and the address to where they're going. I'm not sure that I have everything but it should work well.

  I only did this, but you can use two trays with one who holds a number of pages and the other for a certain number of envelopes.

• Cannot get ePrint or other features on CM1415fnw to work

  Cannot get ePrint or other features on CM1415fnw to work. I can see the printer on the network, proceed to its IP via the wireless, added to ePrint, but apps and some other features do not work. As he never printed the ePrint instructions after that I clicked on the touch screen repeatedly. He just flashed to another screen then returned to the home screen, like nothing happened. I tried print article USA today money through the Apps but it is there for 2-3mins then finally said that he can't reach the web. However, I have on the web right now writing this review from my laptop which is connected to the same wireless router. I sent an email with a few lines of text to the ePrint address, that I was able to locate on the menu diagnastoics by going to the printers IP address. The e-mail never printed but ePrint site shows as pending and that the printer is online. This whole experience has been a joke. I am a network engineer and I know that's not my network. I don't use a proxy and my wireless router and ISP are large open. No firewall or any other nonsense it hangs. It's just bad software/hardware to HP. I also confirmed that the printer has the latest version of the firmware which is 20101125.

  The idea of having this printer works with all features, it comes with would be great. Any thoughts?

  I think I solved the problem. You can't have a USB connection and a network connection to the printer at the same time. I had a USB connection to the laptop and a Wi - Fi connection to printer. I unplugged the USB and then unplugged the printer. I leave a little clear all memory volatile and plugged in. After letting it go online and get it is the IP address of the wireless router, I was able to print to it by sending my email through the connection wireless address ePrint. I am also now able to print from Apps.

  Conclusion, HP needs to fix their firmware in the next version or work with both USB and wireless/wired network connection or provide some sort of pop-up warning that connections are not supported at the same time.

• Windows Update does not load: Windows XP

  RSVP-URGENT! My primary default browser is NOT IE, but I have to use to try to get the UPDATES before it's end of life on October 16, 2014. Please confirm.

  I want to run all Windows updates on it that I can, but now when I try to do with IE, it "cannot find Web site". I ran the network of Diag tool and it says I have no problem connecting and my OTHER browser can search and navigate VERY WELL.

  I do not wish to use IE all the tim, but am forced to use Windows Update. I suspect that Microsoft's servers can be overloaded with a lot of people trying to access Windows Update because they too have Windows XP PRO and try to capture the updates as much as possible before its end of life.

  QUESTION: WINDOWS JUST CRASH AT END OF LIFE OR IT WILL CONTINUE TO WORK, BUT IT JUST WON'T BE ANY MORE UPDATES?

  I think that Microsoft need to disclose all information about this as soon as POSSIBLE! We should not have to buy new equipment, I have to do to keep my computer, and you could lose a client big and long time in this to LINUX instead of Windows.

• LAPAC1750PRO & Cisco 2960-S - LACP issues Switch

  Hello community,

  I currently have a layer 2 Cisco 2960-S switch. It has 48 port Gigabit Ethernet ports and 4 SFP ports. I have Setup 3 VLAN on the switch VLAN 10, 11, 255. VLAN 10 is for my home equipment, VLAN 11 for my Audio/video/server equipment and VLAN255 is my network of comments. It's all behind a normal router from D-Link 4 port every day. All correctly connected working processes.

  I have the LAPAC1750PRO access point, I went ahead and ran 2 Cat6 cables so I could take advantage of the link aggregation 802.3d of the Access Point. I configured the passage from what I can tell properly. The problem is that when I turn on the two links AP causes beating port and stop passing traffic. If I disable the second link (leaving the active primary link) everything is stable. Speed is decent on my laptop, and from my iPad, it's fantastic.

  Does anyone have experience using the Protocol LACP (link Aggreagtion 802.3d) with this Access Point? I really want to use this so I can get 2 Gbps throughput of this device to my other devices.

  I'll be happy to post my Cisco Configuration so if someone is paid enough in that as well.

  Thank you

  Jason

  Senior Network Engineer

  OK - I thought about it. He was not at all a problem with the switch or my setup. This is the problem...

  Here's the question – and how I fixed it.

  1 cisco switch - Configuration:

  !

  GigabitEthernet1/0/1 interface
  switchport access vlan 10
  switchport mode access
  spanning tree portfast
  channel-group mode 1 on

  !

  interface GigabitEthernet1/0/2
  switchport access vlan 10
  switchport mode access
  spanning tree portfast
  channel-group mode 1 on

  That's right - this force LACP on the unit and do not have to worry about negotiating/connections protocols.

  2. access point - if it is already configured - factory reset the unit. LACP must be enabled during active keybord with DHCP boot. After that you can configure it as you want.

  What I had to do so was by default the access point and let it be starting with LACP rebuild - I wonder if this is due to something in the firmware that, once the NIC is configured, they become hardcoded and do not change to different settings?

  Whatever it is - this problem is solved.

• SFE2000 and VLAN

  Before we begin, I want to say that I saw "' responses to my question, but never exactly what I'm looking for, so I create a new post.  I'm not a network engineer, so please forgive my ignorance.

  We are a public library.  We have a network that includes a number of branches, through the central site of the main library.  We show an ASA firewall. We have a Cisco3825 for local and a series of Cisco2800 Internet connection.  We use a system of 192.168.xx.xx, using DHCP network.  We have a number of PCs that are on the network access to the public and they are locked by using various software that prevent people to do much except get Internet.

  What we want to do is to put the public pc in their own network, always using our Internet connection, but not allowing them to see or access one of our 192. addresses.

  We bought a Linksys SFE2000 and it is my understanding that if I use it as a layer 3 switch, we can do what I suggested above.  However, I get so far and I reached my level of incompetence!  We want that all the public pc to come through the SFE2000 and although about allowing the public to use a wireless connection (but that is located).

  Can anyone offer suggestions or point me to a site that will help me?  Thanks in advance and again, sorry for my ignorance.  I look forward to hearing from anyone.

  Well, the router must have at least one interface. If the interface is used otherwise you can simply run it through the router as well.

  If you want to use the features of the ESF L3 basically configure you the VLAN as I've mentioned before. You enable L3 on the ESF, then you configure filtering on the ESF for the VLAN 'public '. Drop everything that goes in your charge of private VLAN.

  The problem is the connection to the router. We must define a new IP subnet for routing between the CPE and the Cisco. So, basically you will need a 3rd VLAN to connect with the Cisco. You can use a very small for this IP subnet if you wish. For example, add VLAN3 with IP address 192.168.99.101/255.255.255.252. The port on the Cisco configure IP address 192.168.99.102/255.255.255.252. On the ESF, set the default gateway 192.168.99.102. Who should route all internet traffic to the Cisco.

• Android access to external hard drive attached to EA6900

  Hello

  I want to have my android device (4.4.4) to connect to an external hard drive attached to my EA6900 - wireless of course.

  What is the best way to do it? Better way

  (a) you don't need to be a network engineer

  (b) access to the files is fast

  I saw someone recommended software EAS, but then they said it took TWO HOURS to make it work. Give me a break.

  Thank you

  Alex

  I have been using an application called File Manager by cheetah mobile. version 2.5.0.442 and it took 5 seconds to access my NAS from inside the network. haven't tried it outside, but I know that I can ftp from the application. I think they have a free version to try, but not sure about that. might be worth looking at.

• Dell Inspiron 13-7352 Wifi dropped unable to connect!

  I just bought this new laptop today with Windows 10 system. Everything worked fine in the first few hours but all to BLOW IT IS No. CONNECTION WIFI. There was just a Red Cross in the symbol of this wifi at the bottom right and when I click on it or plane, or the wifi mode is activated.

  I clicked on bottom of wifi, but it has no light, kept gray. I opened the setting turned on wifi but there is no wifi displayed. I go to the setting for the airplane mode screen and 'WiFi' botton was not on. I clicked on it to try to turn it on but it won't let me. the background moved to 'on' and then bounced back is disabled, gray kept Just... I activated the airplane mode and then turned off and tried repeatedly to turn on the WIFI. It just won't let me.

  And then I restarted the laptop. THEN THE WIFI has WORKS PERFECTLY... at the bottom of the wifi, once restarted, just worked so well, that I could turn it on and off with a simple click. of course different from the previous.

  HOWEVER, AFTER 2 HOURS, EXACTLY THE SAME THING HAPPENED AGAIN... I REBOOTED, IT WORKED AGAIN...

  I think that there's obviously a problem. No way I'll keep restarting my laptop every 2 hours...

  someone has an idea?

  Thank you!

  I also wanted to return the laptop after talking to Dell technical support. They asked more then $100 to repair or buy support for one year for $250. I hope I had help from my son-in-low who is an experienced certified networks engineer and we spent an hour or more on the phone to solve the problem and find the right Wi - Fi configuration.

  Here is the solution that works for my Inspiron 2015 13 7000 2-in-1.

  1. go to the Start button setting.

  2. on the definition of window go to "network and Internet".

  3. in the window "Network & Internet" open "network and sharing Center."

  4. on the window center network and sharing, find connections: Wi - Fi (name of your wi - fi connection)

  5. click on Wi - Fi and open the window state of the Wi - Fi free.

  6. on the wireless connection status window, click the properties button and open the Properties window for the free Wi - Fi connection.

  7. you will see the list of questions for this connection.

  8. attention to two points: Internet Protocol Version 4 (TCP/IPv4) and Internet Protocol Version 6 (TCP/IPv6). On my laptop, the two protocols have been verified.

  9. click on TCP/IPv6. Click OK and close the other windows.

  10. restart the laptop.

  After that my problem has been resolved and I had Internet.

  Hope this will help some of you.

• Buying a server - no help - where is the customer service?

  Hey guys, I'm a looking for a server for the enterprise network engineer, that I work. I have been trying to decide on the right server for my project and was looking for a little help to get the right plug. I tried to use your live chat twice and got ripped off and forgotten and finally talked to someone yesterday a conference call with a guy from the company and he never called me at our time pre arranged.

  So what gives doing you small businesses more?

  I bought my last Dell server and I wanted to once again, but I guess maybe I should go to HP for assistance.

  Virginia.

  Hi Talerian,

  Thanks for posting.

  Several people offered to help you here on the Forum, please give us more information.

  Also, your company will have a representative Dell are attributed to him, have you tried to contact them?  If so, please let me know their name, and I will contact them for you.

  Kind regards
