I've tried to connect to a server via wget:

wget http://<user>:<pass>@serveradress

But wget responds: invalid port

I know that the server accepts incoming traffic at port 80. How can I fix this issue?

Wget interprets <pass>@serveraddress as port. To specify a username and password, use the --user and --password switches:

wget --user user --password pass http://serveraddress/

From man wget:

--user=user
--password=password
Specify the username user and password password for both FTP and HTTP file retrieval. These parameters can be overridden using the
--ftp-user and --ftp-password options for FTP connections and the --http-user and --http-password options for HTTP connections.

I prefer the --ask-password option described by Nabil Kadimi's answer. It has you enter the password invisibly on another line and avoids storing it in your shell history. –  Kevin Apr 8 at 1:23
    
@Kevin You can avoid storing it in the shell history by starting the line with at least one space (as shown by Nabil). If the password/resource is sensitive, then you should worry more about the unencrypted HTTP/FTP/whatever connection than storing it on your disk. –  Lekensteyn Apr 8 at 8:58

You have 3 options and here there are in no specific order other than guts feeling:

1/ Password is visible to anyone (using the command history)

me@machine:~$ wget --user=remote_user --password=SECRET ftp://ftp.example.com/file.ext

2/ Password is visible to anyone looking behind your shoulders

me@machine:~$  wget --user=remote_user --password=SECRET ftp://ftp.example.com/file.ext

Notice the white space before the command, it prevents saving it to your history

3/ Password is not visible to anyone including you

me@machine:~$ wget --user=remote_user --ask-password ftp://ftp.example.com/file.ext
Password for user `remote_user': [SECRET (not visible)]

don't forget to add the following option --no-check-certificate I.E: wget --no-check-certificate --user user --password pass http://serveraddress/ –  عبد النور التومي Jan 5 at 5:10

I don't think you can reliably use the user:pass@name syntax there; wget has separate command line options for those instead, so is probably naively parsing the string after the : as a port number.
