- Adguard DNS works on one of my WiFi networks and on my cellular plan, but not the other one. Anything that could be causing this? I entered the dns server the same way for both of them in settings. This is on my iPhone btw.
| To those who've asked me how to prepare for networking interviews... Posted: 01 Jun 2019 01:49 PM PDT ...and to those who've been blindsided by interviews in the past: Every time someone asks me how to prepare for a networking interview, I'm at a loss for where to start. There are so many factors that can affect what you'd expect to see in an interview. That said, there are some common bits, but giving people the same pieces of advice over and over again makes me feel like this. I decided to update my YouTube channel with actual content for the first time in...geez, six years? Wow. We've gone through two revisions of the CCNA since then, I think! In any case, here's a video on networking interviews. It definitely doesn't cover everything, but it certainly covers the most common pieces of advice I give. This is the result of years of in-person interviews and phone screens, and from a slide deck assembled by /u/HoorayInternetDrama. (That's right, I didn't forget about that slideshow you sent me almost a year ago!) I'm definitely open to feedback on the content (production quality sucks, I know, working on that). Feel free to chip in with other morsels you think you would be useful to the community, also! Mods: I'm 99% sure this doesn't break Rule #5, but I don't want to break rule #3 either. My primary goal here is to have a post to reference when folks ask about networking interviews - not just at an entry level, because I see lots of engineers who should know better make the mistakes I mention. Hopefully the comment discussion can add more context than my video alone. That's the idea, anyway. :P [link] [comments]  |
| I created a free application that has some useful network tools. Posted: 01 Jun 2019 04:03 PM PDT I'm a network engineer by trade, but I created an application called Igloo to facilitate learning Python for SDN and whatnot. It has some granular commands for TCP settings on Windows boxes, as well as simplified IP route/address configs and a built-in TCP port scanner. There are also simple command sets available for configuring Windows client VPNs, creating/deleting local firewall rules, and lots of other neat things. My upcoming additions for the app will be automated server configurations and more network-related tools, like automated crypto configurations for the ASA. I'm also working on SSH client capabilities. Igloo definitely has kinks to work out, but I'm working on it continually to make it better. Feel free to lambast it or offer your suggestions. I hope that someone finds it useful. [link] [comments]  |
| Looking to get a cabling certification Posted: 01 Jun 2019 07:05 AM PDT I am wondering which certification would be the best at the most affordable price. I have been looking at BICSI and obtaining a level 1 cert. [link] [comments]  |
| Posted: 01 Jun 2019 11:02 AM PDT I'm not sure if this is the right configuration for the patch panel wiring legend, anyone can verify? Trying to set up B wiring configuration and asking if the picture seems right and if the next one up would be the same as the one I started ... Thanks in advance! [link] [comments]  |
| Router on a stick (ASA) with dhcp pools on 3750 L3 Switch? Posted: 01 Jun 2019 03:44 PM PDT Happy that I have things running as far as I do... ASA interface gig 0/1 desc TRUNK no nameif no sec-level no ip address interface gig 0/1.10 vlan 10 nameif LOCAL sec-lev 99 ip address 172.20.10.250 255.255.255.0 interface gig 0/1.20 vlan 20 nameif MGMT sec-lev 100 ip address 172.20.20.250 255.255.255.0 interface gig 0/1.40 vlan 40 nameif Printer sec-lev 99 ip address 172.20.40.250 255.255.255.0 Switch 3750 ip dhcp excluded-address 172.20.10.200 172.20.10.254 ip dhcp excluded-address 172.20.20.200 172.20.20.254 ip dhcp excluded-address 172.20.40.200 172.20.40.254 ip dhcp pool VLAN10 network 172.20.10.0 255.255.255.0 default-router 172.20.10.250 dns-server 1.1.1.1 domain-name Local.com lease 30 ip dhcp pool VLAN20 network 172.20.20.0 255.255.255.0 default-router 172.20.20.250 dns-server 1.1.1.1 domain-name Local.com lease 30 ip dhcp pool VLAN40 network 172.20.40.0 255.255.255.0 default-router 172.20.40.250 dns-server 1.1.1.1 domain-name Local.com lease 30 I set up gig 1/0/1 as switchport access vlan 10 switchport mode access spanning-tree bpduguard enable The connection between laptop & g1/0/1 is green. the dhcp server is on, I have debugging on and not seeing anything. The laptop connected to 1/0/1 is giving me an 169.254.x.x address I know its a bad idea to set up an ASA as a dhcp server which is why I'm attempting this. I'm wondering if I'm doing this all incorrectly. I'd rather not have to set up everything as static IP's. I do have an old server running 2008 but I don't want to fight it and get it running again, and there are not many devices to be concerned with. [link] [comments]  |
| Hub and Spoke w/dual WAN BGP Design Question Posted: 01 Jun 2019 09:47 AM PDT Hi all, I'm not a BGP expert by any means, so I wanted to know if there's any BGP config I can use to solve my problem. I have a Hub and Spoke IPSec network. Each spoke has two WAN ports, which has an IPSec tunnel to redundant hubs (two IPSec tunnels per WAN port). Traffic originating from the spoke is routing packets through its WAN1 IPSec tunnel, when the hub is has WAN2 in its route table. The hub is a firewall which, by default, denies asynchronous routing. Is there any BGP setting (except changing the weight for specific interfaces) that can allow the Hub and spoke to negotiate a preferred interface, or tunnel, when they peer? Not sure if this is relevant but the Hub is seeing both of the spoke's interfaces as a BGP neighbor. Thanks in advance [link] [comments]  |
| Asav+ anyconnect on AWS AGAIN!!!!! Posted: 01 Jun 2019 02:47 PM PDT I have asav running on AWS , nothing complex, standard interfaces (inside ,outside, management ). however when a user connects to the anyconnect client they cant reach my internal network btw( int network is connected to AWS over DXGW -direct connect. ) I can of course reach the internal network from the asav inside interface..just not from the anyconnect address pool. I figure its routing. I have an aws route-table associated to inside interface that points to vgw to get to internal network..(btw is already associated with dxgw) . I'm thinking the issue im running into is how does my network know where to reach my anyconnect address pool. My the anyconnect pool subnet is pulled from the supernet block of the vpc. So I can not add a more specific route than the default local route of the vpc. If I were to use a subnet outside of vpc supernet , that subnet isn't advertised over from our csp to our interna network( since it's only configured on the asav). I need to allow my anyconnect network to talk to my internal network. I feel like Ive worked through the basics (SG'asav static routes ,etc) but with no success. Any one ever done this? would greatly appreciate the help. [link] [comments]  |
