I have a dedicated web server, and back in August had a hardware upgrade to a new server (which caused the IP addresses to change). At the time I was at a summer trailer and accessed with an Air Card through the LTE network. When trying to connect via FTP to sites on the server through Dreamweaver, it would connect, but would not show me a file list or do anything, then it would just disconnect. I was able to FTP to and from other sites not on this particular server through the LTE network. The trailer park I was at had wifi access through Cogeco, and I was able to FTP to the server through their network. I thought maybe it was an issue with the LTE network, but now I am home and on my regular Rogers cable internet connection, and I am still unable to access the server via FTP (HTTP, SMTP, POP are fine) and now I do not have the Cogeco wifi to use. I am assuming it is some kind of a DNS issue - any ideas how I could get this resolved?
Solved! Solved! Go to Solution.
In case anyone else experiences this odd problem and is searching here for a solution - I managed to get around this problem by enabling shell access on the accounts and using SFTP instead of FTP. Still have no idea why FTP doesn't work, but SFTP, like all other service, works fine. Thanks again to gdkitty for all your help.
I have tried both actually, and neither works. I thought if for some reason Rogers was using an old DNS table for FTP that accessing the new IP would work, but it doesn't.
You are able to ping that address? (so you have visibility of it)
So it does initially connect? just wont retreive anything?
You could try putting what you are connecting to it with (ftp software, or dreamweaver) into passive mode. I know it helped sometimes with some older FTP servers i used to connect to.
Yes, I can ping it. That's right, it connects but won't retrieve anything, and then disconnects. I have tried passive mode, and non-passive mode and IPV6 mode - nothing works. The only thing that has worked is connecting over a non-Rogers network.
Hmm.. that is wierd.
I dont really have any to try connecting too from home to really test from my rogers connection.
Ultimate test would be to YOUR FTP but i am sure you dont want to pass out that info 🙂
I know its not them blocking FTP all together, etc.. as i was able to connect from work, to my own FTP server at home on rogers today, and coppied a 300mb file.
No, it is not blocking FTP for me altogether either - I am able to FTP to other sites, just not to this particular server (which is the one I partiularly WANT to FTP to!) Could there be something in the router (that would also be in the Air Card?)
In testing through ftptest.net, it connects to the server as it does through Dreamweaver and when trying to get a directory list it shows:
Error: Could not establish data connection: No route to host
Well obviously Port 21 is open and configured because I can connect to other sites, and non-Rogers ISPs can connect to the server. Could it be something that is blocking me because I had connected to the server before on a different IP address and now trying to connect to a different IP.
No, I don't want to publish FTP credentials here, but let me see if I can get a friend who I believe is on Rogers to see if he ca connect to see if it is a general Rogers issue, or if it is just Rogers and me.....
Its possible the its server side blocking it.. depends on their FTP config... but i wouldnt think so.
Did a little lookup.. appears that some firewalls, dont like the MLSD command (its a directory listing command)... so that COULD be it.
Now, you are on a rogers gateway? In gateway mode? or using a 3rd party router, in bridged mode?
I am wondering if its getting stuck, for some reason, on through the NAT on the gateway (why just ONE, i dont know).
I GUESS I am on a Rogers Gateway. It is the router/modem that was supplied and set up by Rogers. And before that I was using the Rogers Mobile Hotspot which also had the same problem. I was able to access the sites fine prior to changing to the new server with a new IP address. I don't know if the NAT router/firewall would clock it because of the IP address change?
