I have changed my php.ini limits /usr/local/cpanel/3rdparty/etc/phpmyadmin/php.ini /usr/local/cpanel/3rdparty/etc/php.ini /usr/local/lib/php.ini Code: max_execution_time = 30 max_input_time = 60 memory_limit = 128M log_errors = On log_errors_max_len = 1024 ignore_repeated_source = Off report_memleaks = On track_errors = Off register_argc_argv = On post_max_size = 2500M gpc_order = "GPC" auto_prepend_file = auto_append_file = default_mimetype = "text/html" include_path = ".:/usr/lib/php:/usr/local/lib/php" doc_root = user_dir = extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20090626" zend_extension = "/usr/local/IonCube/ioncube_loader_lin_5.3.so" extension = "suhosin.so" extension = "pdo.so" extension = "pdo_sqlite.so" extension = "pdo_mysql.so" extension = "sqlite.so" extension = "ixed.5.3.lin" suhosin.request.max_vars = 2048 suhosin.post.max_vars = 2048 suhosin.cookie.encrypt = Off suhosin.memory_limit = 128M suhosin.session.encrypt = Off suhosin.get.max_value_length = 2048 suhosin.get.max_name_length = 2048 suhosin.request.max_varname_length = 2048 enable_dl = Off file_uploads = On upload_max_filesize = 2500M allow_url_fopen = On default_socket_timeout = 60 smtp_port = 25 sendmail_path = "/usr/sbin/sendmail -t -i" sql.safe_mode = Off mysql.allow_persistent = Off mysql.max_persistent = -1 mysql.max_links = -1 mysql.default_port = mysql.default_socket = mysql.default_host = mysql.default_user = mysql.default_password = mysql.connect_timeout = 60 mysql.trace_mode = Off session.gc_probability = 1 session.gc_divisor = 100 session.gc_maxlifetime = 1440 session.cache_limiter = nocache session.cache_expire = 180 Worried if I changed them to too large values? post_max_size = 2500M upload_max_filesize = 2500M I just wanted to be able to upload more higher size .sql file then 100-200MB because I had such database without having to split it or pack it. What happens if specifyed too high value? In means of security and server physical load/status. Total processors: 8 (2xQuad core Intel(R) Xeon(R) CPU E5405 @ 2.00GHz) RAM: 32GB (16x2GB) Interface is running bond mode 6. Anything else I should pay attention in php.ini? I also noticed simply editing /usr/local/cpanel/3rdparty/etc/phpmyadmin/php.ini gets overwritten in time. And by question I don't use port 25SMTP. Only php.ini has it set. Other then that WHM has changed outgoing port into 26 and 587, so is firewall. 25 should be blocked. what mail is going out using that port and can I change it?
