When you try to upload a plugin through the WordPress admin interface, WordPress will make a call over to a function called "get_filesystem_method()" (ref: /wp-admin/includes/file.php:1549). Sebastian Schmid's comment on the original post touches on it but not fully. You can then easily turn it back on again afterwards.There's a lot of similar responses to this question, but none of them fully touch on the root cause. Once you have both scripts, you can easily and quickly turn your firewall on and off and then test whether the problem continues after you have disabled the firewall. # Set default policies for INPUT, FORWARD and OUTPUT chainsĪny similar rules you want to set up you can add in this file, I tend to comment everything to ensure I don't have a brain fart when I return to it later. Iptables -A INPUT -p tcp -dport 22 -j ACCEPT -m comment -comment "SSH" Then create a similar file to lock your server down (I drop all the rules at the start of the script to ensure no unexpected results - note I accept all outgoing connections from my server): #!/bin/bash Iptables -A INPUT -m state -state ESTABLISHED,RELATED -j ACCEPT # Accept packets belonging to established and related connections

Personally I have a shell script in my root folder which I can run to add my iptables rules, I just update it as and when I need new rules adding then run the script, I also have one to open all the ports up to see if there is a firewall issue causing me problems (this is my personal server with nothing business critical on it, I don't recommend you open up all your ports for any length of time if there is anything worth stealing on there).īut if you are able to test, I would recommend you save this locally on the machine (root folder is a good place IMO as root should be the only one who can see the files and then set it's permissions to 700 (chmod 700 filename.sh - I call mine firewall.sh and firewallopen.sh)): #!/bin/bash A OUTPUT -p tcp -m tcp -dport 465 -j ACCEPTĪre there any (obvious) issues with my iptables setup considering the above mentioned issues? Saying that the firewall is doing exactly nothing in this state is also an answer.Īnd again, if you have any other suggestions for me to increase security (considering the basic things I do with this box), I would love hear it, also the obvious ones!

Ssh connections from the terminal are working fine though. I tried opening up the firewall to accept traffic for ports 465 (gmail smtp) and ssh port (lets say this port is 8000), but both the issues remain. I have the feeling that these are both related to the iptables configuration, because I've tried everything else (I think). Smtp (Failed to connect to server: Permission denied (13)) sending emails from my site using the Gmail.installing plugins and updates through ssh2 (failed to connect to.Getting my Wordpress to run as desired, I'm running into some connection problems. I tried to configure the server as default as possible, but I like it to be secure as well (no ftp, custom ssh port). The websites running on it are nothing special, just some low traffic projects. I recently set up a hosted server with Centos 6 and configured it as a webserver. Let me start off by saying that I'm a Centos newby, so all info, links and suggestions are very welcome!
