    Q: Sonicwall high CPU usage

    by m1ckrz on Jun 5, 2015 at 9:47 PM


    Sp we have had high CPU usage on our Sonicwall for the past few days. At first, we thought it was a storm, so we did a full re-patch and the issue seemed to clear up. We don't utilize any end user switches; all our switches are in our server room and everything else is a direct patch.

    Since the re-patch, the CPU steadily climbed back up to hover between 75-95%, but I noticed during downtime it drops to around 20%. The process eating up CPU is tdataplanetask. My tier 3 told me if it was a storm, the usage would be constantly around 99% and would not drop back out.

    I am wondering if it has to do with overhead from our VPN. We are running two site-to-site VPNs, one of which (as I have stated in other posts) is a telemarketing branch that pipes a lot of data.

    Any suggestions on what other occurrences can cause CPU spikes like this on a firewall, and any way to isolate this issue?

    I also just ran a Capsa scan and see no alerts for TTL expiration. CPU was at around 20% this morning, but as soon as our telemarketing branch went active, CPU escalated from 20% to 90% in 3 hours.

    Q: What training should I pursue?

    by Mandelin on Jan 6, 2016 at 7:04 AM

    My boss has asked that I "put together a list of desired training you would like to have in the next 6 months? Also, a list of those vendors that would provide the training, estimated costs, where the training would be held and how that training would help you in your job. " And it needs to "tie into departmental and enterprise goals (which still need to be developed)." I have a week and a half to come up with a list that he will then whittle down the list based on what he thinks we need and he will present it to his boss.

    I am a Network Administrator (been here 4 months), I would like to become the Network Engineer (my bosses job, which he is leaving in 5 years).

    I have 7ish years’ experience in Networking and a Bachelors in Technical Management and Network Communications.

    There are at least 5 new to me systems in my current position:

    SCCM training

    AD 2012 training

    Adtran wireless training

    Nessus training

    colosoft

    I wonder if system by system training is the best approach or should I be looking in a different direction?


    Ans:

    Neally Jan 6, 2016 at 7:54 AM


    AD and SCCM go hand in hand.

    Also as Scott mentioned, the stuff you listed is fairly spread.

    AD and SCCM should be of no concern for a (true) network engineer.
    (Like at our place the networking guys know what AD is, and that's about it)

    I'd look more what you do or expected to do on a day-to-day basis. Depending which you find difficult to do, that's where I'd start. I'd also consider what is what you do right now, and what is what you want to do in 5 years.

    Yeah you said your boss might retire in 5 years, but the question is if you will be still at the same company in 5 years and if you are still interested in the same things.

    If you are really into networking, I'd recommend, as Scott, the Cisco route (CCNP, CCIE).

    I am not sure what Colosoft is, but Colasoft is a packet analyzer software, you want to add to that Wireshark for sure.
    Nessus is just a vulerability scanner.

    Really, your true choices are deep dive into MSFT and be more of a Sys Admin with SCCM and AD, or deepen your knowledge in networking with the CCNP aiming for the CCIE.

    Q: Server/Client Windows Based software to monitor Bandwidth usage?
    by Dustin82 on Jan 15, 2016 at 8:52 AM


    I have a bandwidth leak in my agency. Something is clogging the network at about 10pm daily and I think it might be a virus our scanner can't catch, problem is I have no idea what host it is and I have nothing in place on the firewall/gateway that monitors traffic. I was hoping you could let me know of a software suite that would allow me to centralize a data collection from clients installed on each workstation and each server so I can figure out where this data consumption is coming from. Is there such a product available for an Active Directory domain?

    Ans
    Neally Jan 15, 2016 at 10:26 AM

    Whole network hangs at set times every Hour

    by Rob Thompson - MendMyComputer on Jan 21, 2016 at 8:08 PM

    We have a customer running a SBS2011 network, and every hour between 7&9 minutes past people get issues opening or saving files to or from the server shares.

    In the System Event Log we can clearly see that we have an event ID 7036

    The Volume Shadow Copy service entered the stopped state.

    and then a minute or so later another event ID 7036

    The Volume Shadow Copy service entered the running state.

    We have other SBS2011 customers who also have the same events logged on an hourly basis, who report no such issues.

    Not sure where to look to remedy the situation...

    Ans:

    Neally Jan 22, 2016 at 2:48 AM
    I'd first check all the scheduled things. I think Chris is spot on.

    Everytime we had issues, especially if it was times, it was a backup or replication, or something that took over the whole network bandwidth. When it happens, do you have any bandwidth analyzer? I''d run that and that should help pointing you in the right direction (e.g. capsa free, or even just the resource monitor might help)

    Q: Track internet data upload/download with Wireshark
    by Erick9581 on Mar 5, 2016 at 1:03 AM

    Hi, I downloaded and installed the latest version of Wireshark, in the hopes I could track for a given period of time, how much data has been downloaded and uploaded via the internet. We are looking at upgrading our internet but need to know how much bandwidth we would need for upload and download. After digging around in Wireshark I realize I have no clue what I'm doing with it, so I'm hoping someone has some ideas.

    Ans:
    Neally Mar 5, 2016 at 1:17 AM
    Capsa Free does a pretty good job of tracking who has the most traffic.

    http://www.colasoft.com/capsa-free/

    In general, especially if you are looking for edge traffic, you might be better off looking for a proxy server, or most firewalls have some kind of usage tracker build in. What do you guys have as a firewall?

    Q: Network Monitoring tool

    by GiftedIT on Apr 20, 2016 at 6:39 AM

    What network monitoring tools, hardware or software, are must haves?

    What should I be monitoring daily?

    I have servers, firewall, switches, managed Ethernet, 125+ PCs.

    I want to see failures, problem before the user even detect it.

    Also, does any use smart phones. I currently have alerts configured with email notification. Should I be doing more? Something goes offline and I'm alerted via cell? I have an older cell, and checking email is cumbersome. Might hit manager up for smart phone for work use. But dread the 24/7 catch-22.

    Thoughts?

    Ans:

    faboo Apr 21, 2016 at 3:38 AM

    I use Colasoft Ping Tool. It is a simple ping utility that displays responses in graphical streaming chart.

    Q: How to scan network without providing IP range
    by AFMET on May 23, 2016 at 12:27 PM

    How do I scan all devices connected in my network. I do have spicework, but I need to scan all devices in my network without giving IP/Subnet range. I do have some IP scanners but all works when IP/Subnet provided. I want to know if theres any new switch/hub or any other devices like any wifi APs or any devices connected in my network

    Ans:

    Hi

    Whht is the best tool to identify weird traffic on my LAN? Our firewall can see a connection being made to a suspect, blacklisted, IP in China but because we run a proxy the Firewall cannot see the local IP it originates from.We have run AVG and Malwarevytes to clean/scan all the PC's. Any idea's?

    Question about Dell Sonicwall TZ600

    by TrunkMunki on Aug 20, 2016 at 2:59 AM |SONICWALL

    We currently have an NSA 250M connect to a 100/20 coax connection. With CFS, AV, Anti-Spyware, IPS, and AppControl enabled, bandwidth drops to 18 mpbs down. I'm looking at upgrading to a TZ600, but would like to know if anyone has experience with this model to know for certain if I enable those same services will it tank our bandwith as well?

    Thanks,

    Ans:

    Neally Aug 20, 2016 at 3:08 AM
    https://www.sonicwall.com/products/tz600/#compare

    Before you purchase a new SonicWall, have you run speedtests behind the modem, are you sure it is the sonicwall?

    DO you have something that can capture netflow data?

    Maybe look into Colasoft, to see if there is something that is hogging the bandwidth or of it is actually the sonicwall that gives in.

    TrunkMunki Aug 20, 2016 at 5:15 AM
    Direct to the cable modem I get the full speed, Interfaces are already set to 1Gb on both ends, nothing set to auto.

    I've downloaded Capsa and will attempt to analyze the traffic.

    Thanks
