Q: I have compile/link problems. A: Some common installation problems are described in the INSTALL file. If your case is not covered, please send a problem report. Q: How can I see the greeting message from the server? A: Try `debug 3'. It is disabled by default to keep the screen clear in case of several simultaneous connections. Q: Why doesn't lftp download files like this: `lftp ftp://host/path/file'? A: It expects an URL of a directory. To download a file use `lftpget URL'. Q: What is the %2F in ftp URL's? A: RFC1738 specifies that clients handling ftp URL's should interpret them as HOME relative by default. %2F stands for leading slash pointing to the root directory. Q: Why do the secure protocols https and ftps give the "PRNG not seeded" error message? A: Your system probably lacks a /dev/random-like device. Create a ~/.rnd file containing random characters and SSL will work. See also the OpenSSL FAQ about this. Q: Why does lftp say that locking fails all the time? (on linux) A: You have compiled lftp with large file support (>2G) but your kernel does not support 64-bit file-locking. Either install a better kernel (e.g. linux-2.4.x) or compile lftp without large file support (configure --disable-largefile) Q: Where is lls? A: !ls Q: Why doesn't `mirror' download files starting with a dot (or re-uploads them all the time)? I can see the files on the server using `ls -a'. A: Try `set ftp:list-options -a'. Q: ^Z doesn't work in Cygwin. A: Use "SET CYGWIN=TTY". This must be done before starting a shell, if any. Q: lftp consumes 100% CPU on MacOS X Tiger just waiting at the command prompt. A: See http://www.mail-archive.com/lftp%40uniyar.ac.ru/msg02101.html for a workaround for MacOS X bug. Q: lftp hangs in "Making data connection" state. A: Try "set ftp:prefer-epsv no". Probably a router on the path to the server does not recognize the EPSV command. Q: ssl:key-file setting is not applied to sftp and fish connections. A: Use sftp:connect-program and fish:connect-program settings instead, e.g.: "ssh -a -x -i path-to-key-file"
