ctrace is an IPv4 traceroute tool that supports many features missing
in standard 4.3BSD traceroute(8). It is programmed entirely in perl.
The primary difference between ctrace and other traceroute tools is
its ability to trace routes in multiple protocols. ctrace also has
some additional nifty features:
* Automatic round-trip-time (RTT) averaging, which makes output
cleaner and more intelligible.
* One or more packets can be launched per TTL/hop. By way of contrast,
4.3BSD traceroute(8) forces at least two. This capability makes
ctrace faster.
* 4.3BSD traceroute(8) emulation in most output, so it will hook in to
existing parsers.
* The ability to skip an arbitrary number of hops, saving you time
that would be normally wasted tracerouting your own network.
* Fine-grained control over trace packet headers, assisting in
bypassing burdensome packet filters.
Corkscrew is a simple utility to help tunnel SSH connections through
web proxies.
Add the following line to your ~/.ssh/config file (replacing HOST and
PORT with your web proxy settings):
ProxyCommand /usr/local/bin/corkscrew HOST PORT %h %p
Dante is a circuit-level firewall/proxy (socks implemented) that can be
used to provide convenient and secure network connectivity to a wide range
of hosts while requiring only the server Dante runs on to have external
network connectivity.
Once installed, Dante can in most cases be made transparent to the clients
while offering detailed access control and logging facilities to the
server administrator.
DeleGate is a general purpose protocol proxy system for protocols that use
TCP/IP. This software includes support for HTTP, Gopher, FTP, SMTP, NNTP,
POP, Telnet, Wais, Whois, etc.
A light-weight DHCP Relay Agent.
Why not the ISC DHCP Relay Agent?
- If your RA has multiple interfaces, you get multiple requests for
each request:
DHCPREQUEST for 10.199.14.216 from 00:10:dc:d1:e6:39 (foo) via 10.199.14.1
DHCPACK on 10.199.14.216 to 00:10:dc:d1:e6:39 (foo) via 10.199.14.1
DHCPREQUEST for 10.199.14.216 from 00:10:dc:d1:e6:39 (foo) via 10.10.3.5: wrong network.
DHCPNAK on 10.199.14.216 to 00:10:dc:d1:e6:39 via 10.10.3.5
This RA sends only one request, coming with the IP address of the
LAN the request came from.
- If your RA has multiple interfaces, the outgoing interfaces to
the WAN needs to be active in the DHCP relay otherwise answers
are not picked up.
This RA uses a unicast socket for returning answers.
- If your RA has non-ethernet interfaces (GIF-tunnels for example,
which VPN back to the central network), the answers are not picked
up by the RA.
OpenConnect server (ocserv) is an SSL VPN server. Its purpose is
to be a secure, small, fast and configurable VPN server. It implements
the OpenConnect SSL VPN protocol, and has also (currently experimental)
compatibility with clients using the AnyConnect SSL VPN protocol.
The OpenConnect protocol provides a dual TCP/UDP VPN channel, and
uses the standard IETF security protocols to secure it. Both IPv4
and IPv6 are supported.
Ocserv's main features are security through provilege separation
and sandboxing, accounting, and resilience due to a combined use
of TCP and UDP. Authentication occurs in an isolated security
module process, and each user is assigned an unprivileged worker
process, and a networking (tun) device. That not only eases the
control of the resources of each user or group of users, but also
prevents data leak (e.g., heartbleed-style attacks), and privilege
escalation due to any bug on the VPN handling (worker) process. A
management interface allows for viewing and querying logged-in
users.
gogoc is gogoCLIENT, which is needed to connect to Freenet6 tunnel.
Freenet6 Tunnel is an IPv6 access service which enables thousands of people
from all over the world to experience the best solution for a smooth and
incremental deployment of IPv6. Freenet6 Tunnel users can get IPv6 connectivity
from anywhere, including from behind any NAT device or from outside of their
home network.
GQ is a GTK-based LDAP client. Features include:
- browse and search modes
- LDAP V3 schema browser
- template editor
- edit and delete entries
- add entries with templates
- export subtree or whole server to LDIF file
- use any number of servers
- search based on single argument or LDAP filter
Grdesktop is a GNOME frontend, for the remote desktop client (rdesktop).
It can save several connections (including their options), and browse the
network for available terminal servers.
Grsync is a GUI (Graphical User Interface) for rsync, the commandline directory
synchronization tool. It makes use of the GTK libraries and is released under
the GPL license, so it is opensource. It doesn't support all of rsync features,
but can be effectively used to synchronize local directories and supports
remote targets in a limited way (read: manual).
