Re: Unclassified Disk Sanitizers
C'mon kids, why waste money just to destroy data? It's easier than all that Drop disk in question in a free unix box, then: dd if=/dev/urandom of=/dev/daWhateverdisk If you're really paranoid, put it in a while true, run it all night It takes longer than a blowtourch but get the drive just as hot and delicious without the open flame - Jared Lovell On Thu, 21 Feb 2002, Sadler, Connie J wrote: Does anyone have recommendations for freeware or shareware that effectively erases disks for unclassified but sensitive information? This would be used for all machines retired to school programs, etc We need one for Windows and one for UNIX, if one tool can't clean both types of disks Anybody have experience with this? Thank you!

Re: sftp server
Set the user's shell to something that's not a shell. Some systems have a /sbin/nologin, or you can use /bin/false or something equally harmless. It's proabably gotta exist in your system's list of valid shells (/etc/shells). hope that helps. - Jared Lovell On Thu, 31 Jan 2002, Geeking Out wrote: Greetings, I have someone with which I wish to automate file transfers. I wish to do this securely. I thought that running ssh on the box with key exchanges would do this just fine since i can then use sftp. However, if I install ssh on the box, and I give the client access, they can also log into the box and get a shell. Is there a way in which I can limit them to sftp only?

Re: Ftp box - questionable
Yeah, it probably means that someone has anonymous ftp running for no good reason Consider not allowing anonymous connections, you'll see the number of failed (occasionally, sucessful) attempts to d/l sensitive files drop considerably. Better yet, don't run ftpd at all - Jared On Thu, 17 Jan 2002, Dr Bado wrote: Can someone decipher this??

Re: Secure network-filesystems
NFS over SSH tunnels works for me Not extremely fast, but encrypted traffic rarely is. Since SSH is free or nearly free, it's worth a shot before using anything expensive and/or restricted to a single OS. NFS and SSH is a winning combo if your environment is mixed (alll mojor UNIXes, NT/2000), and adds the benefit of proper authentication. Hope this helps. - Jared Lovell On Fri, 11 Jan 2002, Philippe Seidel wrote: Hello, I just want to set up a central file server offering both public shares and private stuff (home directories and stuff like this) on an OpenBSD box. Everything well, until I realized that both samba and NFS will pass everything unencrypted through the network. Now my question: Are there any free (speech or beer) network-filesystems offering both optional encryption (for the public shares it just gives away computing time) as well as also optional secure (kerberos?) user authentication available both for *nixes (meanpart Linux) *and* Windows 9x? Eventually two different systems, one for the *nixes and one for the windows-machines. Someone in this list just mentioned NFS+, but I didn't find anything at a short google search. What about an encrypted SMB share? Or this mysterious thing I saw in the Linux kernel... Coda? Thanks in advance, Philippe

Re: Which Proxy Server...
Apache (www.apache.org) w/ mod_proxy works fine for http. Apache builds under most anything. For the others, I'm not sure you want a proxy server so much as a NAT service. I've never heard of a telnet proxy, since it's interactive (ie, not stateless file serving like http). Hope that helps. - Jared Lovell On Fri, 14 Dec 2001 [EMAIL PROTECTED] wrote: Dear users, I am planning to upgrade my Proxy Server. It runs on IBM AIX(Unix Like) operating system. I tried to search Proxy Server for Unix on Internet. But the results were not much and also their performances were unknown.
