About
These are some of the non-paid software & utilities I've written from '93. I chose to include here software that could be useful/reused regardless of its complexity or quality.This page was created long before cloud based repos like github and bitbucket were founded, and contains mainly software from that era. All software in this page is free (as in speech & as in beer) with source code available.

scsi_rescan Bash - display and rescan scsi hosts and attached devices
Usage:/\ -- \/ Usage: scsi-rescan.sh [options] http://www.sivann.gr Options: -i interactive prompt for rescan -mExample:issue device rescan for all matching -l list devices (default with following options) -g also show generic scsi devices -v also show model/vendor -p also show iscsi username/passwords -s also show /sys device path -w wider output than 80 columns -r no-header Dislpays a list of: *scsi hosts *driver name per host *block & generic devices per host *iscsi session IDs per host *iscsi initiator and target names per iscsi session id. You are given the option to rescan for new devices for a selected scsi host. Uses /sys without any external dependencies. EXAMPLES: #just list devices in a wide terminal: #scsi-rescan.sh -l -g -v -p -w # ##list devices and interactively prompt for rescan #scsi-rescan.sh -i # ##rescan all SATA ports of VIA controller (sata_via kernel module) #scsi-rescan.sh -m sata_via

scsi-rmdev.sh Bash - remove scsi device from system
- Umounts device
- runs blockdev flushbufs to flush outstanding i/o
- removes device
runcached Bash Python C - Execute commands while caching their output for subsequent calls
Includes 3 interchangeable implementations in bash,Python,C, choose the one you prefer. Usefull in zabbix.GIT Repository is here
runcached (Run Cached) ------------------------------------------------------------------------------ Execute commands while caching their output for subsequent calls. Command output will be cached forseconds and "replayed" for any subsequent calls. Original exit status will also be emulated. After cacheperiod has expired, command will be re-executed and a new result will be cached. Caching depends on command and arguments executed and the path of the runcached executable. Cache results are stored in /tmp You can use runcached to run resource-expensive commands multiple times, parsing different parts of its output each time. Those commands will be run only once for each cacheperiod. Usage: ====== Python: runcached.py [-c cacheperiod] C: runcached [-c cacheperiod] Bash runcached.sh Example: ======== 1) The following runs the date command each time you call it, but produces a new "date" every 5 seconds. runcached.py -c 5 date 2) Query multiple parameters of mysql which correspond to the same time, but run the query once. UserParameter=mysql.globalstatus[*]/usr/local/bin/runcached.py -c 20 /usr/bin/mysql -ANe \"show global status\"|egrep '$1\b'|awk '{print $ 2}'
netchat C - scripted chat with a remote tcp port
This is like "expect" with basic support for scripted chat. Sometimes tcl and perl based "expect" implementations failed mysteriously while interfacing with a Siemens HiPath communication system so I wrote this in C.It's very easy to use and works great for chatting to routers, switches and so on via telnet or other ports.
Writes are delayed to accomodate for slow devices. It does not support ssl. Can be called from scripts, php, cgi et.c.
Script files start with hostname and port on first line and each subsequent lines start with WAIT: or SEND:
Netchat understands these commands: WAIT:<string> waits for <string> (2 seconds timeout) SEND:<string> sends <string> INTERACTIVE: control is given to terminal example input script file: ------------------- 10.1.1.1 23 WAIT:sername: SEND:joe\n WAIT:ssword: SEND:doe\n SEND:who\n SEND:exit\n -------------------
callstats CPHPSQLITE - Phone Call stats for Siemens HiPath OpenOffice ME
Collect & display call statistics for HiPath OpenOffice ME through the web. It may work with other Siemens HiPath devices. Here's a screenshot], which is self-explanatory. Colors are randomized on each page loadIt has 3 parts:
- a software collecting logs from the network to a text file in /var/log (netlog),
- a php command line binary which appends new entries from the text log to an sqlite database
- the web frontend which supports lots of queries
- sqlite 3.x
- Apache (tested with 2.2)
- PHP 5.2.x (or later) with sqlite3 PDO support, and command line php binary
netlog C - IP/tcp_port logger. Log data from a tcp source to file.
It is being used by the callstats program above. The same functionality could be achieved with netcat (/usr/bin/nc -d -k -l [port]) but netcat sometimes stopped logging for no apparent reason. This one worked without issues for several years.
ntd PHP - Network Topology Discovery
- Uses SNMP to query CDP,ARP and other tables from auto-discovered routers and switches.
- Queries ieee.org for MAC Manufacturers
- Creates html, text and graphical (graphviz: PNG and SVG) representation of results
- Shows correspondance of IP/MAC/Switch Ports/VLANS/Switch-Switch connectivity
- Distinguishes CDP neighbors from other connectivity
ipredirectd C - redirect tcp port to same/other server/port and manipulate data based on regular expressions
This was created in 1999, it is similar to netcat, but has these extra features:- supports multiple clients
- supports full logging of network traffic
- supports 2 separate regular-expression based filters/manipulators for client->target (server) and target->client data
Example toclient.pat file:
#syntax:<reggex pattern><tab><replacement> <title>Google</title> <title>Lalala</title> Connection: keep-alive Connection: closeipredirectd Usage:
IpRedirectd version 0.4 , Spiros Ioannou 1999-2010 Usage: ipredirect [-d[d]] [-m ] localport targethost targetport -d debug connections -dd debug all traffic -ddd debug also this software -xfork at most n children -m manipulate traffic using to{client,target}.pat
GPS to DTMF MatlabASMCPicBasicBCB - video geotagging: record GPS NMEA information as audio in video files
A circuit that converts NMEA data to audio. That way GPS information can be recorded to the audio channel of a video camera. Such a device can provide the necessary functionality to create your own geotagged videos resembling the "Street Level Zoom" services of Google and MS.
sivterm.zip BCBWIN32 - serial vt100 term
Sivterm was a simple freeware Win32 RS-232 terminal used to replace the buggy hyperterm. Sivterm does not provide file transfer but it's adequate for line monitoring or testing. It can also be used as a console for routers, switches or unix boxes as it implements proper vt100 emulation. Supports all COM ports, viewing port signals as status leds (TD RD CTS RI DSR RLSD), manipulation of DTR and RTS signals (useful for dumb terminals which always expect DTR to be raised to start talking, like some UPSs). It also features a data monitor that can use several representations (ascii, hex, etc). No install needed. SendStrings and Log was never implemented. [screenshot]The MP3-O-PHONO Project C
This page is about a device (1999) that plays mp3 files from a CDROM. It's a transformed Intel-based PC running Linux and custom software, with an LCD and keypad. It was featured on slashdot and also got some press attention.XGRK CX11 - Write greek in the X-WINDOW System
X11 keyboard "driver". Probably the first multi-OS multi-keyboarard driver of its sort for greek. It enables to change keyboard mapping with alt-shift or meta-shift combinations or by clicking on the displayed flag image. You will be able to write greek in X programs like netscape, xedit or xterm without the need for a special keyboard or driver. Tested with many hardware platforms & unices including Solaris, IRIX, HP-UX, Linux, FreeBSD, OSX e.t.c.
findrefs.vb VB - Find uncited references/citations in MS Word documents
A collection of visual basic word macros I wrote which do the following:- FindUnrefedTablFigures: find uncited/unreferenced tables and figures
- FindUncitedRefs: find uncited/unreferenced references (citations)
- SortRefsByOrderofAppearance: sort references in citation order (order of appearance in text). Backup first for this one.
- other vb macros
TimeTrack WIN32BCB - track automatically where your time is spent

upsesp2 C
Read UPS status with ESP2 protocol. For UPSes like Liebert/Emerson GXT2, NXe, others maybe.upsesp2 version 0.4, 05-Apr-2010: Usage: upsesp2 <serial device> or upsesp2 <serial device> <UPS parameter> example: upsesp2 /dev/ttyS1 LOAD_WATTS The 1st syntax will report a list of supported parameters
upschk C
UPS monitor daemon, for unix- (or POSIX)- compatible OSes. Works with Advance-Intelligent UPSes such as X power Piconet and Micronet, Megatec, Falcon SG, et.c Tested only with the X Power Micronet. This code has been tested with linux & Solaris 2.7. It should compile on other unix boxes with little or no modification. I wrote this in a couple of days to replace the original idiotic java monitoring software (winpower,http://www.ups-software-download.com) that takes up more than 40MB of memory just for monitoring and another 40MB while configuring(!). Moreover, it didn't work at all. The upschk daemon worked fine so far for numerous power-failures.usage: upschk [ -vdi ] -v:verbose mode -d:daemon mode (forks in bg) -i:interactive mode: send cmds to UPS
videograb-0.7.tar.gz C
