I am having a problem with the WebStorm IDE in that I cannot use its built-in FTP capabilities probably due to my OpenSUSE (Tumbleweed) firewall blocking some needed ports. I am assuming that because after turning off the firewall it suddenly works. My problem is that I have no idea what port(s) I need to open because plain ftp from both Firefox and Nautilus work without problems and I am guessing that WebStorm using some other extra protocols. My problem is that I cannot figure out how to determine what they might be. I have told YaST to log all not-accepted packets but using sudo SuSEfirewall2 log gives the following error:
Can't open /var/log/firewall: No such file or directory at /etc/sysconfig/scripts/SuSEfirewall2-showlog line 67.
I can confirm that the file does indeed not seem to exist.
