Our 404 error logs show a lot of /SysVol http requests on our Windows Web Server 2008 for our website. It only has a webserver role and I believe that SysVol requests are meant for Domain Controllers? What's causing this and what would be the best solution to deal with these 404 requests?
I'm using code that access employee records via Active Directory (ldap) and the server is not trusted for delegaton in case this is related to the problem.
Are these requests coming from external IPs ? They are probably trying to p0wn you
The sysvol share generally gets created and shared out when a server is promoted to a domain controller. I'm assuming that your web server is not a DC and not in an Active Directory domain?
As for how to deal with it, if you're behind a firewall, you could block everything except ports 80 and 443 for instance. I hope that your webserver is behind a firewall. Seeing traffic like that isn't all that unusual considering it's on the internet.

I'm trying to upgrade a websocket connection ws:// to wss:// using a nginx reverse proxy https://github.com/nicokaiser/nginx-websocket-proxy/blob/master/simple-wss.conf
but I seem to be having trouble with the certificate part. My server is located on the same network as the client. So Ideally I would want my users to log in to "https://example.com" and then the client makes a connection to "wss://192.168.1.xxx:xxxx".
As of now the browsers are blocking it because of NET::ERR_CERT_COMMON_NAME_INVALID. I don't really know to produce a self signed certificate that the browsers will trust on the local network. Googling only gives me answers on how to do it if my server would be accessed using a domain name but I will always connect to a local network IP. Help is appreciated!
To anyone coming across this I managed to solve it using this post outlining the architecture https://support.plex.tv/articles/206225077-how-to-use-secure-server-connections/
What ended up happening was that we set up a url pointing to a server running nginx which parsed the subdomain and redirected the connection to that url. For example: wss://192-168-1-142.mydomain.com redirects to ws://192.168.1.142 which makes the browser trust the connection
Does this work?
Your post is a year old now and browsers have become stricter since then. Usually, a browser will produce 'mixed content' errors if you access HTTP content from a HTTPS page, and the only way to get round this is to change the site settings to allow insecure content, which is scary for users in the face of a big warning message.
If accessing an HTTPS web address redirects to an HTTP local IP address, won't the browser still complain about mixed content?
I have a similar situation to you. I am writing a Progressive Web Application (PWA) to control network music players on a home network. The players only support HTTP but a PWA requires HTTPS for services workers to work and to allow the app to be 'installed'.
My solution is to run a local server on the home network which can talk to the players over HTTP. Then I can access this server over HTTPS from my browser so that the browser itself is not making any HTTP calls.
This works fine if the server is on localhost because localhost is a special case where security rules are relaxed. But if the server is on another machine, how can I create an SSL certificate since (1) it seems that local IP addresses are not allowed in the Subject Alternative Name (SAN) section of the certificate, and (2) I won't know in advance what the IP address of the server will be.
If your workaround works, then the local server can use HTTP instead so I won't need a certificate. The local server can register itself with a web server, and then the browser can connect over HTTPS to the web server, which would redirect to the IP address of the local server over HTTP.
But does this trick work?
I am very confused with proxy server, and proxy and this word proxy. I saw everywhere people are using proxy program, proxy server. Some of them using the proxy websites to unblock the websites. There are lot of things like reverse-proxy like that..
When I read one article about nginx I ran into one pic it says proxy cache. So what's proxy cache?
And how can I write a proxy program? What does that mean ? Why we need to use a proxy program?
Anybody can answer my question as simple as possible, I am not much in to this area.
A proxy server is used to facilitate security, administrative control or caching service, among other possibilities. In a personal computing context, proxy servers are used to enable user privacy and anonymous surfing. Proxy servers are used for both legal and illegal purposes.
On corporate networks, a proxy server is associated with -- or is part of -- a gateway server that separates the network from external networks (typically the Internet) and a firewall that protects the network from outside intrusion. A proxy server may exist in the same machine with a firewall server or it may be on a separate server and forward requests through the firewall. Proxy servers are used for both legal and illegal purposes.
When a proxy server receives a request for an Internet service (such as a Web page request), it looks in its local cache of previously downloaded Web pages. If it finds the page, it returns it to the user without needing to forward the request to the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from the server out on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it on to the user.
To the user, the proxy server is invisible; all Internet requests and returned responses appear to be directly with the addressed Internet server. (The proxy is not quite invisible; its IP address has to be specified as a configuration option to the browser or other protocol program.)
An advantage of a proxy server is that its cache can serve all users. If one or more Internet sites are frequently requested, these are likely to be in the proxy's cache, which will improve user response time. A proxy can also log its interactions, which can be helpful for troubleshooting.
In my LAN I have two web servers, one Apache Linux Server (Debian) and one Microsoft Web Server (IIS7).
Apache has three webpages, i.e., apache01.com apache02.com and apache03.com and IIS7 has microsoft01.com and microsoft02.com
My question is:
To access from outside LAN to any domain, what is better? NAT port 80 to IIS7 or to Apache?
And then, How to delay from Apache/IIS7 to IIS7/Apache the domains it doesn't manage?
I've never done this, so I ask because it could be a lot of thinks I'm not seeing.
I don't need a full procedure, only a guidelines to continue researching.
Thanks
The solution, here
The key is IIS URL Rewrite Module and Reverse proxy
If I log in to our web server using RDP, I can't access any of the sites we run on that web server via their external url. For example, say my web server hosts www.example.com, when I log in to the web server, bring up a browser and try to go to www.example.com, I can't see it.
However, one of our sites was configured in some way to work like this, if I try to go to that url, it works as you might expect.
Unfortunately, this was done by our server hosting partners, who we are no longer in contact with. Does anyone know how this can be achieved?
You can do it in many way..
It depends on your network configuration, but it could also be a simple row in hosts file or a static dns record or a specific route for that ip address.
if you're using IIS you should also set the website to "listen" on the loopback interface in the bindings menu.
or, for IIS 6:
I am hosting two web pages in my server. One is running on Apache and the another one on Glassfish. By now I solve the redirection problem making the Glassfish server to listen on a port distinct than the 80. The problem is that I think my web users have a firewall blocking those ports so they can´t access the GlassFish web. Which way would you recommend me to take in order to make a URL request-based redirection? I want to make the glassfish web a subdomain of the Apache one, being both running at the same IP.
If I have not been sufficiently clear with my question, please let me know
Thank you for your time.
Have you tried modifying the domain or using subdomains? If one application is eg. at http://subdomain1.yourdomain.net and another at http://subdomain2.yourdomain.net it should do the trick without any problems. Or try http://yourdomain.net for your main program and http://yourdomain.net/somecontext for sub program. That looks meaningful also for the service user.
