NBTSCAN(1) General Commands Manual NBTSCAN(1)NAME
nbtscan -- program for scanning networks for NetBIOS name information
SYNOPSIS
nbtscan [-v] [-d] [-e] [-l] [-t timeout] [-b bandwidth] [-r] [-q] [-s separator] [-h] [-m retransmits] [-f filename |
scan_range]
DESCRIPTION
This manual page documents briefly the nbtscan command.
This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.
nbtscan is a program for scanning IP networks for NetBIOS name information. It sends NetBIOS status query to each address in supplied range
and lists received information in human readable form. For each responded host it lists IP address, NetBIOS computer name, logged-in user
name and MAC address (such as Ethernet).
OPTIONS
A summary of options is included below.
-v Verbose output. Print all names received from each host.
-d Dump packets. Print whole packet contents. Cannot be used with -v, -s or -h options.
-e Format output in /etc/hosts format.
-l Format output in lmhosts format. Cannot be used with -v, -s or -h options.
-t timeout
Wait timeout seconds for response. Default 1.
-b bandwidth
Output throttling. Slow down output so that it uses no more that bandwidth bps. Useful on slow links, so that ougoing queries
don't get dropped.
-r Use local port 137 for scans. Win95 boxes respond to this only. You need to be root to use this option.
-q Suppress banners and error messages.
-s separator
Script-friendly output. Don't print column and record headers, separate fields with separator.
-h Print human-readble names for services. Can only be used with -v option.
-m retransmits
Number of retransmits. Default 0.
-f filename
Take IP addresses to scan from file "filename"
scan_range
What to scan. Can either be single IP like 192.168.1.1 or range of addresses in one of two forms: xxx.xxx.xxx.xxx/xx or
xxx.xxx.xxx.xxx-xxx.
BUGS
Report bugs to alla@sovlink.ru (that's autor of nbtscan). I cannot promise to do anything but I might well want fix it. Remember: no war-
ranty. At least it's worth what you payed for it.

pure-authd(8) Pure-FTPd pure-authd(8)NAME
pure-authd - External authentication agent for Pure-FTPd.
SYNTAX
pure-authd [-p </path/to/pidfile>] [-u uid] [-g gid] [-B] <-s /path/to/socket> -r /program/to/run
DESCRIPTION
pure-authd is a daemon that forks an authentication program, waits for an authentication reply, and feed them to an application server.
pure-authd listens to a local Unix socket. A new connection to that socket should feed pure-authd the following structure :
account:xxx
password:xxx
localhost:xxx
localport:xxx
peer:xxx
end
(replace xxx with appropriate values) . localhost, localport and peer are numeric IP addresses and ports. peer is the IP address of the
remote client.
These arguments are passed to the authentication program, as environment variables :
AUTHD_ACCOUNT
AUTHD_PASSWORD
AUTHD_LOCAL_IP
AUTHD_LOCAL_PORT
AUTHD_REMOTE_IP
AUTHD_ENCRYPTED
The authentication program should take appropriate actions to fetch account info according to these arguments, and reply to the standard
output a structure like the following one :
auth_ok:1
uid:42
gid:21
dir:/home/j
end
auth_ok:xxx
If xxx is 0, the user was not found (the next authentication method passed to pure-ftpd will be tried) . If xxx is -1, the user was
found, but there was a fatal authentication error : user is root, password is wrong, account has expired, etc (next authentication
methods will not be tried) . If xxx is 1, the user was found and successfully authenticated.
uid:xxx
The system uid to be assigned to that user. Must be > 0.
gid:xxx
The primary system gid. Must be > 0.
dir:xxx
The absolute path to the home directory. Can contain /./ for a chroot jail.
slow_tilde_expansion:xxx (optional, default is 1)
When the command 'cd ~user' is issued, it's handy to go to that user's home directory, as expected in a shell environment. But
fetching account info can be an expensive operation for non-system accounts. If xxx is 0, 'cd ~user' will expand to the system user
home directory. If xxx is 1, 'cd ~user' won't expand. You should use 1 in most cases with external authentication, when your FTP
users don't match system users. You can also set xxx to 1 if you're using slow nss_* system authentication modules.
throttling_bandwidth_ul:xxx (optional)
The allocated bandwidth for uploads, in bytes per second.
throttling_bandwidth_dl:xxx (optional)
The allocated bandwidth for downloads, in bytes per second.
user_quota_size:xxx (optional)
The maximal total size for this account, in bytes.
user_quota_files:xxx (optional)
The maximal number of files for this account.
ratio_upload:xxx (optional)
radio_download:xxx (optional)
The user must match a ratio_upload:ratio_download ratio.
Only one authentication program is forked at a time. It must return quickly.
OPTIONS -u <uid>
Have the daemon run with that uid.
-g <gid>
Have the daemon run with that gid.
-B Fork in background (daemonization).
-s </path/to/socket>
Set the full path to the local Unix socket.
-R </path/to/program>
Set the full path to the authentication program.
-h Output help information and exit.
EXAMPLES
To run this program the standard way type:
pure-authd -s /var/run/ftpd.sock -r /usr/bin/my-auth-program &
pure-ftpd -lextauth:/var/run/ftpd.sock &
/usr/bin/my-auth-program can be as simple as :
#! /bin/sh
echo 'auth_ok:1'
echo 'uid:42'
echo 'gid:21'
echo 'dir:/home/j'
echo 'end'
