Anyone know how to allow users other than root to wall messages to other logins? wall "test" only displays to other users if doing it from root. Do i need to be in a certain group? -- Karl Hiramoto <karl(a)hiramoto.org> Work: 978-425-2090 ext 25 Cell: 508-517-4819 Personal web page: http://karl.hiramoto.org/ AOL IM ID = KarlH420 Yahoo_IM = karl_hiramoto

The biggest problem usually isn't the messaging client itself, secure or insecure. The biggest problem is the users who don't understand the technology under it. Inside of Stratus we've done a lot of education to get users to understand that IM is a completely insecure medium and that no business information is to be transmitted over it. Once you explain to Suzy accountant that when she pasts the financials into the IM window and send it to her coworker that they shoot out the door, zip half way across the country and then come back and anybody in between can read them, it suddenly hits home... I only wish that Trillian supported Jabber. I deployed a Jabber server and it worked, but the clients for windows were so crummy that nobody used it.

If the policy is "no instant messaging clients", I don't think I'd load jabber, then argue the finer points. Especially if disciplinary action is noted for violations. If nothing else, make the case for an INTERNAL server, but GET APPROVAL before using it. Jabber has much to recommend it for such a server. > They sight a concern that it is an insecure network link to the outside > world that could allow hackers, worms, trojans, viruses, etc ... into > the otherwise protected network.

Again, I'd get approval first, but IRC can do much of what you want. There are plenty of Win clients and servers for it. - Bob _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

Salvage flashdisk

Tim, Here is one software I have heard was good, but have never used, Photorecovery. It is offered for XP or Mac OS 10. The demo is free. http://www.lc-tech.com/photorecovery.htm If you try it and it works, please let me know.

Instant Messaging Software
by Simoncini, Matthew 19 Mar '04

19 Mar '04

Hey guys, I work at a large company in Natick that has recently decided to disallow instant messaging clients from being used on corporate PC's. They sight a concern that it is an insecure network link to the outside world that could allow hackers, worms, trojans, viruses, etc ... into the otherwise protected network. Whether I agree with this opinion or not I guess is irrelevant as I don't have a strong enough voice to change anything. What does affect my team is the ability to easily communicate with each other on a "live" or instant platform within the company firewall (we have no interest really to communicate outside the firewall yet). I was wondering if anyone could point me in the direction of an Open Source alternative to an instant messaging platform? For starters I'm just looking for software to run on a server (either Linux or Doze) and the associated clients to use on primarily XP or 2000 desktops. I'm doing some research on Source Forge and other sites to see if I can find something myself, but would prefer a suggestion from someone who's already implemented something like this. Thanks in advance. Matthew

Yeah, I tried that and the camera comes back with "Card Error". Oh well, I think this card is fubar.

Most cameras have a very simple format utility that will write a new partition table to the disk, and won't try to be smart about it like your pc. Also it my be the case that you have reached the write limit for the flash card. Compact Flash has a fixed write limit before the cells start to go bad. More to the point a given cell can only be switched from a 1 to a 0 n number of times (blank flashes are all 1's not 0's). -Matt Quoting "Keller, Tim" <Tim.Keller(a)stratus.com>: > I've got a 32mb flash disk that's gone bad.

Hi, One thing you can check out is a project from RPI called lily http://www.freegroups.org/lily-twiki/bin/view/Lily/ and http://www.lily.org/ There is information about how to set up your own server and there are clients for a ton of platforms.

Re: [Wlug] Network configuration with OpenLDAP

Since I have never managed a multiuser *nix evironment I believe the best thing for me to do is follow the KISS principle and attack the problem one piece at a time. The first step is to setup a robust multiuser environment that allows clients to authenticate onto the network via linux shells. These users will initially login either at the console or remotely via SSH. Ideally a VPN will be eventually be added to the mix. The next step will be to setup samba to allow clients to authenticate onto the network via windows. Finally setup ldap and migrate the authentication services to it. >I was also looking into this at my work.
