password encryption?
by Mariann 13 Jul '00

13 Jul '00

Hi, Still experimenting with Samba 2.0.7 This question is about password encryption. It says in the SMB-HOWTO-6.html to set encrypt passwords = yes smb passwd file = /etc/smbpasswd in smb.conf, which I did via swat. Then it says to make some changes in HKEY_LOCAL_MACHINE\system\currentcontrolset\services\rdr\parameters on a WinNT machine. I tried to find this on a Win2000 box, with no success. Does anyone know what's the equivalent for this in Win2000 regedit? The reason I started playing with encryption was that is asks me for a username and password when trying to access a share on the Linux box from the win2000 one. Even though I enter a valid linux username and password it doesn't let me in. cheers, Bodri

> Bodri, > Not sure about 2.0.7, but with earlier (2.0.4 I think) there was no need to change the NT registry unless you wanted to remove the use of encrypted passwords and use plain-text. I would have expected this to still be the same (but could be wrong!!) so make sure you need to before doing so.

1. did you remove the share from smb.conf? - samba will show a share that is defined even if the directory has been deleted. 2. Did you restart samba? - /etc/rc.d/smb restart Cheers Peter aka the pleb who had to learn more about smb filesharing than he ever wanted to know...... _______________________________________________________________ Peter Nixon Systems Engineer Jigsaw Technology Pty Ltd URL: http://www.jigsaw.com.au <http://www.jigsaw.com.au/> Address: 21 Boomerang Place Seven Hills NSW 2147 Australia Phone: 02 9672 4222 Fax: 02 9672 4211 Email: peter(a)jigsaw.com.au _______________________________________________________________ -----Original Message----- From: Mariann [mailto:mariann@lineone.net] Sent: Thursday, 13 July 2000 7:48 To: suse-security(a)suse.com Subject: [suse-security] samba207 Hi, I'm using Samba 2.0.7 and I'm experimenting with shares at the moment. I created a share on my SuSE 6.4 box and accessed it from a Win2000 machine. Than I deleted this share entirely, and expected that I wouldn't be able to see it anymore from the win2000 box (after refreshing the view in windows explorer) but the opposite happened. What could be the explanation and the solution for this? advTHANKSance Bodri

ipchains: unknown ICMP requests ...
by Patrick Frisch 13 Jul '00

13 Jul '00

Hi there, we're using ipchains as firewall. Everything seems to be fine, but now and then, we're getting ICMP requests (PROTO=1) from low ports (1-8) to our webservers at ports 0 or 1. I can't figure out, what's the matter with this requests, it doesn't seem to hurt anyone, that the requests are blocked by our firewall. Is there any intelligent DENY-rule for this sort of requests ? bye, P. -- Dr. Patrick Frisch A.I.S. Angewandte Informations-Systeme GmbH Tel.: +49-234-9734-542 Fax.: +49-234-9734-520

fdisk fails with disks >32GB: no RAID
by Security 12 Jul '00

12 Jul '00

Hello, I have to set up a backup server with software RAID 5 on three Maxtor IDE 60GB discs with SUSE Linux 6.4. (2.2.14). Raidtools are installed. Problem: fdisk displays only 53000 cylinders. That seems to be "cylinders modulo 65536". checking startup messages and /proc shows correct parameters for all three drives. I know, IDE is slow, but the important point is security of large data, not speed. Does anyone know a quick solution (newest beta-kernel would do fdisk right, but is very unstable!) Thanks for all help, Bernhard

Thanks for your help. Here is the solution for large disks: 1. upgrade to Kernel 2.2.16 from SUSE 7.0a (on SUSE FTP-Server!) 2. mk_initrd 3. lilo 4. cfdisk -z /dev/hdabc 5. install RAID 5. I´ll try this now... Bernhard

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: tnef < 0-124 Date: Mon Jul 10 19:19:16 CEST 2000 Affected SuSE versions: 6.3-6.4 Vulnerability Type: remote compromise SuSE default package: no Other affected systems: all unix systems using this package ______________________________________________________________________________ A security hole was discovered in the package mentioned above. Please update it as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s). Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue. Please note that we provide this information on an "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package. _____________________________________________________________________________ 1. Problem Description Tnef extracts eMails compressed with MS-Outlook. The compressed file includes the path name to which the decompressed data should be written. 2. Impact By specifing a path name like /etc/passwd and sending a compressed mail to root an adversary could gain remote root access to a system by overwriting the local password database. The same could happen if a mail virus scanner, like AMaVIS, process' a malicious mail. 3. Solution Update the package from our FTP server. It's also possible to use the '-x' option of tnef to specify the outputfile. ______________________________________________________________________________ Please verify these md5 checksums of the updates before installing: AXP: cc4983da1084c911998ddcc589050ec2 ftp://ftp.suse.com/pub/suse/axp/update/6.3/ap1/tnef-0-124.alpha.rpm ae9b2d0e3231ee9ce35ee2fe0bd7788d ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/tnef-0-124.src.rpm 451485d86daa2b45ae897dc88bf8a61b ftp://ftp.suse.com/pub/suse/axp/update/6.4/ap1/tnef-0-124.alpha.rpm 4bd689ba7abb7235b84570a90b3875d8 ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/tnef-0-124.src.rpm i386: 5909688f8568eb1f14591c1428235777 ftp://ftp.suse.com/pub/suse/i386/update/6.3/ap1/tnef-0-124.i386.rpm 5c02ff06d98030541afb10c178a206f3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/tnef-0-124.src.rpm 58fa8e976df90aa09c30bf8fd5f6b2b5 ftp://ftp.suse.com/pub/suse/i386/update/6.4/ap1/tnef-0-124.i386.rpm 1a99d0cd8315ae3a1990781b7977c4c6 ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/tnef-0-124.src.rpm PPC: 3be0b423e678923f27c42f8c59c09ab4 ftp://ftp.suse.com/pub/suse/ppc/update/6.3/ap1/tnef-0-124.ppc.rpm 5f7f8c3c025c2f114aa115532e250723 ftp://ftp.suse.com/pub/suse/ppc/update/6.3/zq1/tnef-0-124.src.rpm b37d6374a7b0147dbd6bf9889ec68367 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/ap1/tnef-0-124.ppc.rpm 695fcd009a345638f049200dc0d6279d ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/tnef-0-124.src.rpm ______________________________________________________________________________ You can find updates on our ftp-Server: ftp://ftp.suse.com/pub/suse/i386/update for Intel processors ftp://ftp.suse.com/pub/suse/axp/update for Alpha processors or try the following web pages for a list of mirrors: http://www.suse.de/ftp.html http://www.suse.com/ftp_new.html Our webpage for patches: http://www.suse.de/patches/index.html Our webpage for security announcements: http://www.suse.de/security If you want to report vulnerabilities, please contact security(a)suse.de ______________________________________________________________________________ SuSE has got two free security mailing list services to which any interested party may subscribe: suse-security(a)suse.com - moderated and for general/linux/SuSE security discussions.
