Free simpserver 2.1.0 software for linux

diskfree project is a shell script designed to be run periodically from cron to let you know how much disk space youve used, what directories have grown, which directories have shrunk, etc.
Installing
1. If you have Bash installed, then edit line 1 and point it to Bash. If you dont have Bash installed, but have the Korn shell installed, edit line 1 and point it to that (typically #!/bin/ksh).
2. Decide which directories you want reported on or if youre paranoid, remember to use the -p option. If you want something other than the default then use the -d option
3. Decide who should get the report. If it should go to root, dont do anything. If it goes to someone else, use the -m option (-m someone@somewhere.net)
4. Decide where you want the files this script creates to be put. If /tmp is OK with you, do nothing. If you want them elsewhere use the -l option (-l /var/log)
5. Decide how frequently you want the report run (daily, weekly, monthly, etc) If you want it run daily, then create on entry in your crontab like:
00 00 * * * /some/path/diskfree
If you want to run it monthly as well, I suggest you also add this to crontab:
00 02 01 * * /some/path/diskfree -e monthly
And quarterly would appear in crontab like:
00 04 01 */4 * /some/path/diskfree -e quarterly
6. Save your crontab.
7. Copy diskfree.8 /usr/man/man8
8. Wait for the script to run TWICE, then check your email and review the report
9. Send comments, bugs, suggestions to dhunley@columbus.rr.com
Enhancements:
- Altered the output to put the df output first and the details second.

gperfmeter displays performance statistics for a given hostname.

If no host is specified, statistics on the current host are metered. You can display performance values in a solid or line strip chart.

The performance data automatically scales to accommodate increasing or decreasing values for the host machine. The gperfmeter preferences sheet provides a simple interface for accessing all of the application resources.

Download Sentinel++ is an Anti-leech, download limiter / file manager, that uses tokens to verify downloads instead of HTTP_REFERER or IP which can be spoofed or changed.
The install is as painless as possible with only one file to upload and execute. The install automatically creates the sub-directories and files, all you need to do is follow the on-screen instructions for permissions.
Security has been the focus throughout development, even the install program is built on the latest recomendations for security. Logging is done with text files and can have errors and alerts sent via email or stored in a txt file.
Downloads can be limited to a certain transfer size per time frame, which can be further broken down into smaller intervals, all with only a couple settings. This helps spread out the limitation to different timezone and prevents all available bandwidth being used in a short period
Main features:
- Completely free (free as in speech);
- Multiple language capability (all text is in config file, no hardcoded messages);
- Download counter file;
- xhtml/css compliant message output, fully customizable;
- Install script for easy setup;
- All user supplied input securely handled;
- Uses tokens to validate download requests. A superior method than .htaccess or http_referer which can be spoofed or limit users with firewalls;
- Tokens are good for a day by default, but can be set to expire at any time in 1 minute increments;
- A log is kept of invalid token attempts and information on tracking down the source;
- All errors and warnings can be written to a log file or sent to an email address;
- Supports unlimited directory structure of downloadable files (no need to specify where a file is located);
- Option to turn off bandwidth protection;
- Option to turn off any error/log report;
- Robust error handling;
- Ability to specify the total amount of transfer (bandwidth) allowed, over the total amount of time;
- Ability to specify interval lengths for download cut-off so all the allowed bandwidth does not go to one time zone / day /hour;
- Ability to put in a ratio of download clicks to actual bandwidth used;
- Log of all download details kept;
- Download log can be auto-archived;
- Ability to specify the download log size before archive;
- Ability to specify the download archive size before deleting;
- Ability to have a warning issued (email or log file) about the archive file reaching its maximum;
- Download count can be tracked in a Mysql database;
- Flood control on user clicks. Ability to set the number of times a user can click on a link in a given interval;
- Ability to allow specific offsite downloads via tokens;
- Pre-made example download page that is xhtml/css compliant;
- Pre-made file manager that displays all files, directories, sizes, downloads, dates, authors and descriptions for each file
- Ability to deny link sharing between browsers.
- Alternative install locations for secure files
- Logs automatically rotated, no on-going maintenance
- Ability to have multiple files with the same name
- Turn-Key install operation. Ready to begin secure downloads in 5 minutes or less;

socklog cooperates with the runit package to create a small and secure replacement for syslogd. socklog supports system logging through Unix domain sockets (/dev/log) and UDP sockets (0.0.0.0:514) with the help of runits runsvdir, runsv, and svlogd.
socklog provides a different network logging concept, and also does log event notification. svlogd has built in log file rotation based on file size, so there is no need for any cron jobs to rotate the logs. socklog is secure, small and reliable.
Enhancements:
- With this version, the socklog-conf program creates the socklog service directories in /etc/sv/ instead of /etc/socklog/, and names them socklog-unix, socklog-klog, etc.
- Additionally, it creates a ./check script in the socklog-unix service directory, which is utilized by runits sv program when starting or checking the service.

SimpServer is the first lightweight instant messaging security gateway for Unix systems. Install SimpServer on a Unix system and configure IM clients on your local network, and conversations with Simp-equipped parties will be automatically encrypted. SimpServer can indeed accept simultaneous remote connections and thus secure local and/or remote clients.
With SimpServer, corporate environments can now benefit from centralized instant messenger encryption. Linux fans can now secure their MSN conversations. SimpServer is beta and is free for any use.
Main features:
- This version of SimpServer supports MSN Messenger, ICQ, Yahoo! and AIM encryption using the Diffie-Hellman key-agreement scheme. It does not currently support authenticated modes such as the RSA modes of the Windows version, nor does it support other IM protocols. That limitation brings an important advantage: SimpServer can be used as a security server for multiple IM clients, not only the one on the local machine, but others on the network. It is indeed possible to configure clients to use SimpServer as a proxy server, which will secure all outgoing IM flows.
-
-As for the Windows version, the Unix edition can be highly customized: messages can be colored depending on their cryptographic state and contact names can be prefixed during conversations (MSN) to quickly see if the conversation is secure.
