Free samba netbios forwarder software for linux

Active port forwarder is a software tool for secure port forwarding. Active port forwarder uses SSL to increase security of communication between a server and a client. Originally, it was developed to forward data point to point.
However, the need for bypassing firewalls in order to connect to internally located computers influenced the further development of the project.
AF is dedicated for people, who dont have an external ip number and want to make some services available across the net.
Moreover, zlib is used to compress the transferred data.
Using one, permanent data/control channel with flow control / packet buffering provides good performance and reasonably small latency.
Running afserver does not require root priviledges, nor does it use threads or other processes.
Enhancements:
- The bug in the ip_listen function (visible on the systems without IPv6 support) has been fixed.

SMBNetFS is a Linux filesystem witch allows you to use samba and microsoft network in the same manner as the network neighborhood in Microsoft Windows.
Main features:
- you can use Samba/Microsoft network as a regular unix filesystem
- workgroup/computer/share entries are dynamically created
- windows domain supported
- user defined workgroup/link/hosts are supported
- national character supported
- you can access any computer in the world by "cd mountpoint/ip-addr" command, where "ip-addr" is the IP address of the desired computer. Do not warry that there is no file with such name :-)
- command "cd mountpoint/username:password@computer_or_ip" allows you to access "computer_or_ip" as user "username" with password "password" (this is insecure, but usefull)
- the program is multithreaded, so simultaneous access to a file/share is possible
- config file is reloaded automatically if it was changed
- sources
Enhancements:
- A bug in Samba/locale conversion that appeared in 0.3.7 has been fixed.

My Network Catalog is an indexing engine that allows Windows shares (or Samba shares) to be bound together over a local network.

My Network Catalog allows an easy centralized search of all the files available over the network.

smblansearch is set of integrated tools that help you to find and download files you need on samba shares.
It consists of:
sls_main - frontend for sls_scanner
sls_scanner - console smb-scanner
qsmbdownloader - simple smb-downloader, that supports resuming and recursive downloads.
Enhancements:
- added size filtering
- sls_main sends workgroup name to sls_scanner now. this should fix bug with smblansearch and domain

Sambascan2 is a small bash-script, which can scan for SMB-shares in a given Netz.
The project currently needs nmap, find, smbclient, sed and grep. If you know a less agressive way for scanning on port 139, please tell me, because I thing nmap is not so polite.
sambascan2 was only written to scan in public shares and not in private ones (this may change with the time).
It is possible, that the Share have a directory with other permissions than the one needed to access it. Check the permission of the wanted directory, and if Samba can access it as the public user.
Enhancements:
- This version adds the ability to scan password protected shares, using known logins and passwords for the host being scanned.

SMBGate provides a gateway and firewall with authentication managed by a Samba Primary Domain Controller. The firewall rules are set on a per-user basis.

Aps is a small tool for analyzing network traffic. It prints out a great deal of information about the relevant protocols including TCP, UDP, ARP, and ICMP.
It allows you to filter IP addresses, hardware addresses, ports, and specific protocols. It comes with a little GTK-GUI displaying packet counters for each protocol.
APS tries to print detailed info about network frames that are received from the SOCK_RAW (ETH_P_ALL) socket. I am not sure if this is the clean way, but it works fine. APS prints info about the hardware layer and the IP and TCP/UDP/ICMP header.
The tail of the packet (mostly the data) wich could not be interpreted is written on the screen as ascii/hex-dump or both (your choice).
