I have a hosting account with Linux shared hosting account with GoDaddy, recently my ssh access stopped working, this is the error:
Toms-MacBook-Pro:production tom$ ssh tomheather50#192.186.452.73
ssh_exchange_identification: read: Connection reset by peer
This happens on my wifi connection however if I create a mobile phone hotspot and connect through my phone's 3g network I can successfully connect with no errors....
I have contacted GoDaddy support various times over the past 2 days and they have not been much help at all, simply put they have said I should just connect through the mobile network!!
After sending a traceroute to them I got this response.
We are tracking instances of connections dropping and being
intermittent through Level 3 and their IP 4.34.191.254. I noticed
that your connection that is having difficulty is being routed through
this path while the connection that did work is not routing through.
We are reaching out to Level 3 Communications to see if they can
identify and fix this situation. We are seeing more cases like yours
pop up from both Europe and the US. In the meantime I would recommend
using a connection that does not trace through Level 3 if at all
possible.
I'm not sure what means and it staggers me that GoDaddy can not ensure i can connect through my wifi connection !
Any advice, explanation and of course help would be great please guys.
The message indicates an internet connection issue in the Level3 network (i.e. somewhere in between your wifi network/internet provider and the godaddy site). Nothing that either you or godaddy can do to fix it, only Level3 can.
The suggestion is to use an alternate path, which happens when you use the 3G's network provider (instead of your internet provider). By chance I might add - the path between some 3G providers and godadday can still go through Level3's affected network.
Eventually Level3 will fix the issue (large providers usually do that pretty fast) and things will come back to normal.
It's always a good idea to have an alternate provider, your 3G one helped.
BTW: traceroute is the tool to check which path packets go through between your machine and the server you want to reach: https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man8/traceroute.8.html

After lot of struggle, I fixed the ssh connection refused by simply running the following command.
sudo dhclient

I have created a server-side and client-side console based Chatroom. I have done the port forwarding and also added the inbound rule to the firewall settings both in client-side and server-side. It is working fine with computers on the same network but when I connect to the server/socket with different network(mobile hotspot) it doesn't work. I know my public ip address and I have it tried using it also. I am using TCP connection and a port-'55555'. I have windows 10 os on my laptop. Also tried after disabling the virus protection, it didn't work.
Can you please suggest some ideas regarding how to make it work?
This has taken me about a year to understand and get to, but I am the limit of my capability so reaching out to a StackOverflow guru please...
I would like to, if possible, secure my network model. The model is as shown in the diagram. To explain:-
All the aspects I have control of, is within the green shaded area. I cannot change anything outside this.
I run a simple application web server which is the VPN IPsec/L2tpd client. Static IP.
My router is ISP provided. It receives a DHCP Dynamic IP from the ISP.
My Digital Ocean Virtual Private Server has a static IP. It runs an NGINX reverse proxy that channels traffic through the VPN tunnel. It also runs the IPsec/L2tpd server.
A IPsec/L2TPD VPN tunnel is established and working.
A working VPN tunnel.
A cellphone that runs an app that communicates with my application server app. My cellphone receives a dynamic IP from my Network Operator.
I have three IP camera feeds served by my application server. Not a great speed but watchable in real-time.
I cannot change my ISP, or bandwidth/download/upload speed.
I cannot install VPN clients on the cellphone and I may want to access my app server through another cellphone provided by work so cannot install apps on it but does have unfettered web access through a browser.
Everything is now working, can't believe I've done it !
Anyway, my question is:-
Is there any way to secure the network so that only traffic from my mobile reaches - or rather is accepted - by my application server.
I accept IPsec/L2tpd is not great, but it is fast and I use this because I have tried OpenVPN, SoftEther and key based OpenSwan. These are waaaay to slow. The camera feeds are unwatchable and update one frame about every 5 seconds.
So with the limitations above, what can I do, what is possible? Please may I respectfully ask that you refrain from suggestions and concerns requiring a change to that which I cannot control, i accept all critique but that is not what I need here. I am asking for advice on how to secure , that which I can influence. Thank you
I cannot install VPN clients on the cellphone and I may want to access
my app server through another cellphone provided by work so cannot
install apps on it but does have unfettered web access through a
browser.
Due to the limitation that at the end, even a phone where you are not allowed to change anything but use the web, i suggest to configure proxy authentication on the nginx reverse proxy. I don't have experience with setting this up with nginx in particular but that's what should do the trick according to the network architecture and description you provided.
An example configuration on how to configure nginx for basic / client certificate auth can be found at: https://www.cloudsavvyit.com/1355/how-to-setup-basic-http-authentication-on-nginx/
I am trying to connect to a university server using a VPN client. I can connect to the client. Also, if I ping the server by name and by IP address, they both work:
ping servername
ping serveripaddress
However, I cannot access the server from the browser if I type:
\servername
\serveripaddress
and also I do not see anything in Network apart from my own computer. I changed my Workgroup to the correct Workgroup, and it still doesn't work.
Also, as my DNS suffix I use the domain name as well as the FQDN, but it doesn't work either.
I restarted after each of these changes, but it didn't help.
I read that when I have a VPN connection working and I am also able to ping the server to which I want to connect, it is most probably DNS resolution problem. But I do not know anymore what to do (I checked and tried the correct DNS suffixes).
Do you know what should I do more? I am using Windows 7.
Thank you.
It sounds like you're trying to use UNC pathing. Assuming that you're getting your network settings from DHCP, are you getting a WINS server?
I disable the internet connection and run the node server npm start, then it throws the error:
And now enabling internet connection and running the server works fine:
So, I want to confirm if this really needs to be connected to the internet while starting the server?
If it really needs internet connection, then is there any idea to run the server offline?
If I connect to the internet and run the server and there after plug out the internet connection then there's nothing goes wrong. Everything works fine. I don't know why just running the server requires the internet connection.
OMG! It's really cool! I got it working offline after hard research in my code using 127.0.0.1 instead of localhost for mongo uri.
Using localhost needed for me to connect to the internet.
And using 127.0.0.1 worked in both condition i.e. with internet connection and without internet connection.
But, really I'm totally amazed of this.
I found the really cool topic on this which made me clear about this.
If you use 127.0.0.1, then (intelligent) software will just turn that directly into an IP address and use it.
And there's no guarantee that your hosts file will actually be used for that resolution (first, or at all) so localhost may become a totally different IP address.
I've a sitecore azure deployment 2.0. Unfortunately, when I try to run this from company network I get the error below:
A connection attempt failed because the connected party did not
properly respond after a period of time, or established connection
failed because connected host has failed to respond 213.199.180.206:80
When I try below on the same machine it works:

Wondering what exactly is causing the above issue given both 443 and 80 works well via IE.
Thanks.
Definitely sounds like a corporate firewall/gateway problem. Have written a blog post with my experiences of just these types of issues. http://reservoirdevs.wordpress.com/2013/10/18/sitecore-azure-walkthrough-and-gotchas/
My solution was to try from outside the corporate network. It then worked fine.
This sounds like your firewall on your Azure machine is not set to allow incoming http traffic on port 80. Although there could be a lot of other reasons for this timeout.
