I have Ubuntu 10.04.4.

I downloaded and installed scala (.tgz archive), unpacked into /opt, set rights for read and execute in bin for all users. Also updated PATH in /etc/environment

When I run program just with scala command, though name is autocompleted it is not run:

root@ubuntu:/home/user# scala
  The program 'scala' is currently not installed.  You can install it by typing:
  apt-get install scala

But if I use full path to executable it works.

Executables from scala/bin is in PATH (autocomplete works). What am I doing wrong?

root@ubuntu:/home/user# which scala
root@ubuntu:/home/user# whereis scala
scala: /opt/scala-2.9.2/bin/scala /opt/scala-2.9.2/bin/scala.bat /opt/scala/bin/scala /opt/scala/bin/scala.bat
root@ubuntu:/home/user# echo $PATH
${SCALA_HOME}/bin:${JAVA_HOME}/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
root@ubuntu:/home/user# echo $SCALA_HOME
/opt/scala

root@ubuntu:/home/user# cat /etc/environment 
JAVA_HOME="/usr/lib/jvm/java-7-oracle"
SCALA_HOME="/opt/scala"
PATH=${SCALA_HOME}/bin:${JAVA_HOME}/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

It took some time while I tried to find solution over the net. Nothing helped. The story: I have Ubuntu 10.10 (Amazon EC2 instance). ProFTPD Version 1.3.2e (latest via apt-get). I changed nothing on server and ftp clients, but suddenly my clients (filezilla 3.5.3, TotalCmd) ceased to connect via FTPS to server.

Log from Filezilla:

Status: Connecting to 7x.xxx.xxx.xxx:21...
Status: Connection established, waiting for welcome message...
Response:   220 ProFTPD 1.3.2e Server (XXX) [7x.xxx.xxx.xxx]

Response:   234 AUTH TLS successful
Status: Initializing TLS...
Error:  GnuTLS error -9: A TLS packet with unexpected length was received.
Status: Server did not properly shut down TLS connection
Error:  Could not connect to server

Here is from ProFTPD tls.log:

May 04 14:28:32 mod_tls/2.2.2[1057]: TLS/TLS-C requested, starting TLS handshake

Proftpd tls config:

</IfModule>

Clients verified on ftps://ftp.secureftp-test.com:990 (test server for FTPS), connection is ok. Then I tried adding TLSRenegotiation none and other options I found over the net - for no result. Tried reboot - no result.

Tried: openssl s_client -connect 127.0.0.1:21 -starttls ftp:

What can be done else? I want my ftps back. What is typical behaviour in similar situations if no exact solution?

linux ftp ssl ftps proftpd
