Many people prefer to protect their privacy and in many respects I think the 'net would be a much better place if more people did. Just because he does does not make him a cracker, nor does it invalidate his opinions (which I happen to share despite my not using an alias or being a cracker). If a system is concerned about security, then they should take measures to follow bug lists and disable services as bugs are discovered to maintain it. If not, then they will likely not know about the fix when it is re- leased either, and their system will be open to attack anyway. I see no reason to withhold information from those who will use it for the sake of those who (most likely) will not---at least it puts the security folks and the crackers on (more) even footing.

are there any plans to provide T.Rex (http://www.opensourcefirewall.com/index.html) for SuSE? it sounds all very interesting ... just doesn't currently support my favoured distribution ... *greetz* from Vienna Hannes -- Johann Georg Hautzinger, email: trema(a)eic.at, Tel.: 531 00 1907 Erste Bank AG - OE 0423 - Orga./Entw.

Then let's have two announcements: A hole has been discovered in X which allows [basic description of the security violations]. Please disable it until a patch is available. and the standard one, with an in-depth description of the problem and patches (and expoits if you aren't idiologically opposed to them). If all the locks are broken, it would be wise to tell those living in the subdivision to stand guard with a shotgun until the lock can be fixed. Pete

Re: [suse-security] Network question

If you are using Suse 6.2 and Intel EtherExpress Pro 100 cards, we had a similar experience and upgrading the drivers to the 'newnet.rpm' (available on Suse updates area) solved it for us.

Network question
by list 01 Mar '00

01 Mar '00

Hi! I know, this is a security board, but I have a network question and I can't resolve the problem. I have tryed all thing I know and I'm a network engineer. (I know what I'm do..) I always get collisions on my eth1, internal nic. Some pc's are connected over a half duplex hub. The nic's and the cables are ok. My questions is now.. Sometimes the data stream get frozen for about 3 or 4 sec. Can I push up somethink like windows size or something else I can try to get a better result? What I can adjust for earn a fast constant data stream without these connection errors?? Thanks for you help, Chris

Fw: [suse-security] SuSE Security Announcement - make-3.77
by Magus Ba'al 01 Mar '00

Here's the way I see about new bugs, they've been there for who knows how long, maybe since the beginning or since the last update/patch. That means it could have been days, weeks or years that this bug has been there, why does it matter if you don't know for a few more days, it's not like they find it and all the sudden ALL the crackers know about it. So what if you don't know for a few more days, it gives the author time to fix the bug, and then post the new version/patch, so then inform you and all the crackers that the bug exists. What if there is no workaround other than to take down the entire box until the fix is available, then what, you're SOL? I'd rather not know about it for a few days, have an update available, then be informed so I know that it wasn't public knowledge so others could exploit me.
