Connection To FileZilla FTP Server Works, But Directory Listing Fails


Answer :

While this question is old, there's no really comprehensive answer. So I'm adding one.



In the passive FTP mode (the most common mode nowadays), the FTP server listens on port 21 for an FTP control connection. But for all data transfers, including directory listings, it listens on an additional port. The port is picked out of a configured port range.



If you open only the 21 control port on the firewall, you get the described behavior. You can connect, but you cannot list directories or transfer files.



For details, see my article on Network configuration for passive FTP mode.



You have to go to Control Panel > System and Security > Windows Firewall > Advanced Settings > Inbound Rules > New Rule and add a new inbound rule for data port range your FTP server is using.



Firewall inbound rule ports



The port range that the FileZilla FTP server is using, is configured in Edit > Settings > Passive mode settings > Use custom port rage. You can configure a narrow range (like 10 ports), to limit a number of opened ports. You should use port numbers 1024 and above (up to 65535).



FileZilla passive custom port range



FTP needds more than port 21 (and it does not need UDP). The ports for the data connections are dynamic. If the server is behind a firewall you should try active FTP mode, if the client is behind firewall you should try passive mode. If both are behind restrictive firewalls which are not able FTP as a special protocol you are out of luck.



Try changing the Transfer mode to "Active".



To address this FTP error, follow below steps:




  1. Open Filezilla, go to Edit -> Settings

  2. Click on Connection -> FTP: Choose Active

  3. Click on Connection -> FTP -> Active Mode: Select “Ask your operating system for the external IP address”

  4. Click on Connection -> FTP -> Passive Mode: Choose Fall Back to Active Mode

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
