Strange connectivity issues between workstations and Servers

linux-howto

http://serverfault.com – I have a situation whereby there are 3 sites. Site a - User site Site b - User site Site c - datacentre Site a can talk to site c fine Site b can not talk to everything in site C In particular, workstations in site b are struggling to communicate properly with site c. For example - there are servers that we can ping, tracert, even telnet on port 80 (or other app ports) to but cannot for example browse network shares on them. Microsoft Network Monitor shows connections are made during these attempts, but I cannot browse and get the following message: "\\server\share" is not accessible. (HowTos)

I have two separate physical sites, Site A and Site B. In site A, I have following:

2 CAS servers 2 Hub Transport servers 2 Mailbox servers 2 Edge servers

In site B, I have the following:

1 CAS 1 Hub 1 Mailbox 1 Edge

Currently everything is working out of site A. That is, all users are housed on mailboxes that are in site A and all inbound mail flow is pointing to site A.

I remember a few monts ago, I visit a high quality web site. If I remember, I learned that site from github.

In the site, you can build your own linux server with all featers like Ram, HDD, CPU etc.

It was very expensive site but; when you select minimal feature for all, it was free.

And this site not for just a host site. The site was like some kind of a developer site.

nginx ssl with CA 6 weeks 1 day ago

I have a Premium SSL Cert with a provider and they sent me chain.cer, site.pem and site.cer.

I have migrated a site from a external Linux server to a new IIS server. DNS settings have been updated and are showing correctly in whois, squish.net, traceroute. However, when I type in the domain, I am still looking at the old site on desktop. Mobile version via cell (not LAN) is pointing to new site.

I have an existing site at my.site.com and I would like to setup a staging subdomain (staging.my.site.com). I have my DNS setup and directing staging.my.site.com to my server, but for some reason the Web Site I created in IIS for it is not being hit. Instead when I go to staging.my.site.com it takes me to the original site.

I have got a Windows Server 2003 box running IIS6 and a website that i want to set up for HTTPS. I have added the SSL cert to the site and confirmed that the site is available internally using localhost, and although it throws a Certificate Warning, i can carry on and access the site.

However, the site is not available at all externally.

I'm struggling with getting Virtual Hosts running on my local Lion development machine.

Here's the scenario.

Having a baffling time trying to troubleshoot an issue between 3 sites on a WAN set up via site-to-site VPN.

The sites are:

NY: 10.30.1.0 (HQ) OH: 10.30.6.0 CT: 10.30.7.0

When I first started working on it, the OH and CT sites are able to communicate to NY with traffic going both ways, no problem.

After some troubleshooting on their Fortinet firewalls, I essentially added site-to-site
