There is also a seperate FREESCO FAQ system at http://freescofaq.hopto.org/ with a lot more FAQ's, so I suggest you check that out too.
FREESCO can generate a so called 'report.txt' 1). Login as root via console, telnet and issue the command:
report
This will create a file called report.txt in the router directory of your FREESCO.
An alternative method is to login as admin via the web control panel via a browser on a client 2)and click the 'System' link under Info. The system information will appear in the main window of the control panel, where you can use copy/paste to save this information in a text file. This article describes the various ways to generate a report in more details.
Finally, post your report.txt as attachement in the appropriate section of the FREESCO forums and add a description of your problem and stuff you've already tried.
Mainly because the 2.0 kernel is small enough to fit on a floppy and still have enough room for all the other goodies that are packed into FREESCO.
Switching to a 2.2 kernel maybe feasible, but this requires a rebuild of all the binaries and basically a complete rebuild from the ground up for FREESCO. Don't expect a release with the 2.2 kernel any time soon!
The 0.3.x series has reached a stable level and development of the above mentioned FREESCO, based on a 2.2 or even 2.4 kernel will begin shortly after the last 0.3.x release.
This is due to a damaged packet arriving at your machine. This packet didn't quite make it intact across the Internet / your network and the router sees this and tells you. There is nothing you can really do about it and it doesn't cause any problems. It is not a sign that someone is hacking your computer (allthough it can be).
If you frequently gets lots of these messages, it may mean that you have some bad network cabling, network interface or a bad Internet connection.
About evey hour the BIND4 name server dumps messages like this in your system log file:
named[3565]: XSTATS 824681342 824600158
RQ=6 RR=2 RIQ=0 RNXD=0 RFwdQ=0 RFwdR=0 RDupQ=0 RDupR=0
RFail=0 RFErr=0 RErr=0 RTCP=0 RAXFR=0 RLame=0 Ropts=0
SSysQ=2 SAns=6 SFwdQ=0 SFwdR=0 SDupQ=5 SFail=0 SFErr=0
SErr=0 RNotNsQ=6 SNaAns=2 SNXD=1
The first two numbers for each message are times. If you subtract the second number from the first number, you'll find out how many seconds your server has been running. (You'd think the name server could do that for you.) The NSTATS message lists the types of queries your server has received and the counts for each. The XSTATS message lists additional statistics.
The statistics under NSTATS and XSTATS are explained in more detail in this article.
This is 'by design'. The telnetd of FREESCO can only handle a single client connection at a time.
Installing the OpenSSH add-on package will allow you to login as many times as you want AND in a secure way (did you know that the telnet protocol sends the root password in readable text over the (hostile) internet link?). Additional bonuses of OpenSSH are the once-you-know-it-can't-imagine-living-without-it port forwarding/tunneling capabilities.
Higly recommended!
