I searched for a while, but couldn't find anything similar to my problem, so hopefully I didn't miss posts...
I have a CPanel box with a few IPs and a few dozen accounts on it. My current dumbfound-worthy problem revolves around a particular client who is having problems transferring files via FTP with his account.
He hasn't registered a domain name, so he logs into FTP with his account into a Cpanel account I made for him on one of my other IPs. He just uses the IP address and the full username "username@account.com". It's ONLY being used for FTP access.
Anyway, this has worked great for months but now he's getting a funky problem where he uses an FTP client to log in and start transferring files. He will get a file downloaded up to around 1.2MB and then it hangs. There are several other people in his same building accessing the same FTP server account, as well as using other FTP accounts set up for testing... they all have had the same problem: log in fine, but the transfer stops at 1.2MB and hangs.
I am going to ask him to try setting the FTP client to "passive" and "non-passive" modes to see if one works over the other, since I found a post here about that with another issue.
I can access files on the account from here with no problems, and I have a friend testing it from his house and he gets in there fine... all with the same FTP account as the user with the problems.
I am using the ConfigServer Firewall (lfd/csf), but I don't think that's an issue here, since he's logging in fine.
Well... I'll shut up and hope someone has time and a suggestion!
Thanks HUGE for any help!
