Re: Not able to read a RSS feed from a WordPress website
Hi Dave, The server hosting WordPress was blocking the IP address of server running ColdFusion because it was seeing too much traffic for the news feeds from the server running ColdFusion. I just wish the hosting company which was running WordPress had told me this before. I appreciate all your assistance and time. Packets can leave which server? Your CF server? The relevant question here (to me) is: what happens when you ping the WP server from the CF server console? What happens when you run a traceroute to the WP server from the CF server console? Anyway, I appreciate all your assistance and time. You're welcome! Good luck!

Re: Not able to read a RSS feed from a WordPress website
Thanks Dave. This is no longer a programming issue, though. It has nothing to do with reading and displaying the RSS feeds at this point. Instead, it has to do with fixing the connectivity problem between the two machines. People on a mailing list are not going to be able to help you do this effectively. And, you should be able to demonstrate to a network administrator somewhere (your organization, the hosting company where your CF server is) that this is not a CF problem but rather a networking problem. I agree, but here is where it becomes strange. They(hosting company where your CF server is) claim packets can leave the server, but then they are getting lost on the route so tell me to check with the hosting company where the wordpress website who say that they are not blocking any requests from the machine running CF server. I need to dive into it and solve it. Anyway, I appreciate all your assistance and time.

Re: Not able to read a RSS feed from a WordPress website
Thanks Robert, but don't think they(hostingcompanyA) would block a particular IP address(server running CF which belongs to hosting company B) Yes, they would if they detected something funny coming your server... like a bunch of pings or form bots or something... for that matter a bunch of unexpected reads of the RSS file your reading could have set off some kind of alarm that caused them to block the IP. It depends on them and what they see as an intrusion. A lot of hosting companies are great professional companies that can really analyze threats... a lot of them are some guy with a server or two in basement too and anything odd they see they block. Yes, it's possible they blocked you intentionally if they saw a lot of unexplained requests coming from your server. I checked with the hosting company(hostingcompanyA) who host the website my machine running CF is trying to access and they told, they are not blocking the IP address of the server running CF. try displaying it in a browser that shows the same external IP address as your server How do I do that? If the server is at a separate location (hosting company), you may have to ask them for help with this. Yes, that is with hosting company B and they say we are not blocking the website your CF server is trying to read. Honestly, at this point with what you know this does not sound like a job for a programming issue and it may not be best for a programmer to be troubleshooting it. You should get a network engineer to take a look. Hosting company B says we are not blocking the website your CF server is trying to read. They say all is well with the machine running CF server. We went with a hosting company because network engineers in our organization did not have time for such things. Reading the RSS feeds and getting them to display is my task.

Re: Not able to read a RSS feed from a WordPress website
Thanks Dave, Just to clarify: from the machine running CF, if you use a browser, can you get to the site correctly? No, I cannot access the site from the machine running CF. If the server admin can't tell you why a machine he or she manages can't get to a remote server, you need to replace your server admin. I am not the decision maker who can replace server admins. The server admin told me they do not restrict outbound traffic nor there are any rules in firewall blocking that site. I already checked the localhosts file and nothing in it also could be stopping it. Well, the CF service was restarted and so was the server, so if the DNS entry changed, CF should have updated its cache. 1. Should I change the below line in C:\ColdFusion9\runtime\jre\lib\security\java.security #networkaddress.cache.ttl=-1 to something like networkaddress.cache.ttl= 14400 2. Also, does CF9 cache a positive lookup forever? Meaning if http://www.testsite.com/?feed=rss2 was on IP address A.B.C.1 when CF cached it, it will not update its cache when the feed's IP address changes to A.B.C.10 If you can't get to the site from a browser on the machine running CF, I wouldn't bother messing with CF - the problem isn't with CF. If you can get to the site from a browser on the machine running CF, but CF itself can't get to it, there's probably some sort of DNS caching issue within CF itself.

Re: Not able to read a RSS feed from a WordPress website
Thanks Russ, you need to do some basic tests, which your server admin should have already done. for a start ping the domain from the cf server, does this work and do you get the right IP, if not then it is a dns issue. make sure that someone has not created an entry in the local hosts file. I did a ping and the request timed out. All data packets were lost. The server admin told me they do not restrict outbound traffic nor there are any rules in firewall blocking that site. I already checked the localhosts file and nothing in it also could be stopping it.

Just to clarify: from the machine running CF, if you use a browser, can you get to the site correctly? No, I cannot access the site from the machine running CF. It's possible the issue is not on your side. It could be on the side of the site you are trying to read from. You can't display the site in a browser on the CF machine... try displaying it in a browser that shows the same external IP address as your server. It's possible your IP has been blocked by the firewall on the sending side. If that's the issue it will have to be fixed on their side.

Looks like the CF server can't connect to that host on that port. This could be all kinds of things, but it probably doesn't actually have anything to do with CF itself. Perhaps the CF server is on a network segment that can't access this server. Perhaps the DNS entry changed for the WP server, and the CF server hasn't updated its cache.

If you can get to the site from a browser on the machine running CF, but CF itself can't get to it, there's probably some sort of DNS caching issue within CF itself.

Re: Not able to read a RSS feed from a WordPress website
you need to do some basic tests, which your server admin should have already done. for a start ping the domain from the cf server, does this work and do you get the right IP, if not then it is a dns issue. make sure that someone has not created an entry in the local hosts file.

Are you using a browser from the machine running CF? No, the machine running CF cannot access the website. I get a message that the request timed out. But, the server admin cannot tell me what could be causing it. 1000's of people can access the website properly from their computers. Just to clarify: from the machine running CF, if you use a browser, can you get to the site correctly? If the server admin can't tell you why a machine he or she manages can't get to a remote server, you need to replace your server admin. Well, the CF service was restarted and so was the server, so if the DNS entry changed, CF should have updated its cache. 1.

Not able to read a RSS feed from a WordPress website
Hi All, Below is the code which was working fine till yesterday for reading a RSS feed from a Wordpress site running Wordpress 3.9.1 -- cftry cfset rssUrl = http://www.testsite.com/?feed=rss2; cffeed action=read source=#rssUrl# query=entriesNews properties=info timeout = 180 ul cfoutput query=entriesNews startrow=1 maxrows=3 cfset tempTextNews = #title# cfif len(tempTextNews) gt '75' lia class=NewsEvents href=#rssLink# target=_blank#Left(tempTextNews, 75)#...more/a/li cfelse lia class=NewsEvents href=#rssLink# target=_blank#title#...more/a/li /cfif /cfoutput cfcatch type=any !--cfdump var=#entriesNews# --- !--cfdump var=#info# --- News Feed Temporarily Unavailable /cfcatch /ul /cftry -- http://www.testsite.com/?feed=rss2 is a valid RSS feed and I confirmed that with http://validator.w3.org/feed/ www.testsite.com is something I am using here for posting instead of the actual website which provides the feed. If I use a browser, I can see the feeds. Using a feed reader in Google Chrome browser, I can notice the feeds load correctly. If the above code is loaded in a page called testfeed.cfm, I get the message News Feed Temporarily Unavailable. We are using ColdFusion 9 on a Windows server with IIS. The details of error are Detail: Check if the specified host on the port is accessible. Message:Connection refused by the specified host on the specified port. StackTrace: coldfusion.syndication.FeedReader$ConnectionRefusedException: Connection refused by the specified host on the specified port. at coldfusion.syndication.FeedReader.getInputStream(FeedReader.java:394) 1. What could have caused a working WordPress RSS feed which was parsed correctly by ColdFusion till last week to stop suddenly? 2. How can I resolve the issue? Any suggestions would be appreciated.

What could have caused a working WordPress RSS feed which was parsed correctly by ColdFusion till last week to stop suddenly? 2. How can I resolve the issue? Looks like the CF server can't connect to that host on that port. This could be all kinds of things, but it probably doesn't actually have anything to do with CF itself. Perhaps the CF server is on a network segment that can't access this server. Perhaps the DNS entry changed for the WP server, and the CF server hasn't updated its cache. Etc, etc, etc. Dave Watts, CTO, Fig Leaf Software 1-202-527-9569 http://www.figleaf.com/ http://training.figleaf.com/ Fig Leaf Software is a Veteran-Owned Small Business (VOSB) on GSA Schedule, and provides the highest caliber vendor-authorized instruction at our training centers, online, or onsite. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:359246 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
