how to open ports
by Florian Winger 16 May '02

Hi everybody, I´m using an openmcu server on Suse 8.0, because I want to hold multi video conferences. I´m able to connect to this server, but there´s no transmition of sound and video. So I scan with nmap -p 1-65535 [localhost] and look there only the lisenport 1720 is open. All other ports which should be open are closed. Is there any possibilty to open the ports by hand? I don´t care if all ports are open, cause I only use this Server in my LAN which is protected by a different firewall. By the way I already removed all firewall packages on the localhost with yast2.

AW: [suse-security] SuSEFirewall2 - Primary Domain Controller

I guess its the same Problem i have with W2K-Server and an NT4 PDC, when they are in the same subnet, all is ok. But when they are in different subnets, they get no securityinfo from the PDC. I can access the shares, ping it by name. When i try to join the Domain, it gives an Error. When i'm in the same subnet and join domain, everythings ok. When i then change the subnet back, then W2K only gets the S-Numbers instead of the names from Users. I haven't found a fix for this Problem yet. My solution was a second Network only for the Servers, to connect W2K with NT4 in the same subnet.

Well, not really solved yet ;( Working with names works now, but my w2k Client still cant find my PDC (when i wanna join my domain), but it can ping it "ping pdc". do i have to enable some ports for internal routing?

SuSE Linux' imap packages were compiled without RFC1730 support, so SuSE Linux is not vulnerable to this bug per default. - dhcp A format string bug was found in the DynamicDNS (DDNS) code of ISC's DHCP server software. New RPMs are currently being build. - imlib Due to packaging failures we have to re-release the imlib packages which should be available within the next days. This update addresses missing dependencies and affects applications like xcdroast. - perl-Digest-MD5 A bug was found in the UTF8 interaction between perl and perl-Digest-MD5 which leads into failures while verifying the MD5 hash. New RPMs are currently being build. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.

The PDC and Domain is in lmhosts. Under NT4 it only works with this Entry on the clients in another subnet, but W2K does not. The only thing i could not try is to change the name of the Domain.

You're not seriously telling me you didn't find anything on Google, are you? Try http://www.google.com/search?q=pop3+proxy+linux&sourceid=opera&num=0&ie=utf- 8&oe=utf-8. As for SMTP, try postfix.

SuSE Security Announcement: shadow (SuSE-SA:2002:017)
by Sebastian Krahmer 16 May '02

16 May '02

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: shadow/pam-modules Announcement-ID: SuSE-SA:2002:017 Date: Thu May 16 12:00:00 MEST 2002 Affected products: 8.0 Vulnerability Type: local privilege escalation Severity (1-10): 5 SuSE default package: yes Other affected systems: No. Content of this advisory: 1) security vulnerability resolved: write() disruption in shadow utils problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The shadow package contains several useful programs to maintain the entries in the /etc/passwd and /etc/shadow files. The SuSE Security Team discovered a vulnerability that allows local attackers to destroy the contents of these files or to extend the group privileges of certain users. This is possible by setting evil filesize limits before invoking one of the programs modifying the system files. Depening on the permissions of the system binaries this allows a local attacker to gain root privileges in the worst case. This however is not possible in a default installation. The bug has been fixed by ensuring the integrity of the data written to temporary files before moving them to the appropriate location of the system. There is no workaround so we recommend an update in any case. It is necessary to update the shadow package as well as the pam-modules package in order to prevent the truncation attacks. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. i386 Intel Platform: SuSE-8.0 ftp://ftp.suse.com/pub/suse/i386/update/8.0/a1/shadow-4.0.2-88.i386.rpm a4e0d03ecf7707eb7ca1f0422cae89f1 ftp://ftp.suse.com/pub/suse/i386/update/8.0/a1/pam-modules-2002.3.9-31.i386… 70322584f014ac3e2dc2dad0beecdefb source rpm: ftp://ftp.suse.com/pub/suse/i386/update/8.0/zq1/shadow-4.0.2-88.src.rpm 33af2433d9a8822202e9f6ebdc6d3e2c ftp://ftp.suse.com/pub/suse/i386/update/8.0/zq1/pam-modules-2002.3.9-31.src… 1bc5bbd169ffe5c35caa0a4ce681dcc0 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - leafnode The permissions of "/etc/leafnode" have been corrected. Please update to the newly available packages if you use leafnode. - xf86, xmodules, xloader Incorrect permission checks in certain X11 functions allow local attackers to read or write shared memory segments they should not have access to. Corrected packages will soon be available on our ftp-servers. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion. All SuSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SuSE's announce-only mailing list.

secumod+problem+2.4.18
by João Seabra 16 May '02

16 May '02

Hi all I installed secumod (compiled for 2.4.10-4GB). Im using kernel 2.4.18 (installed and compiled by me). When I do a insmod -f secumod.o (because I get a warning about kernel version mismatch 2.4.10-4GB!=2.4.18) profs=1 the module is inserted but nothing happens. Users are still able to see each other procs. I tryed to compile secumod for 2.4.18 but I get alot of warnings and errors about the includes. Any ideas? Thank you very much Best Regards, João Seabra

SuSEFirewall2 - Primary Domain Controller
by mario ohnewald 16 May '02

16 May '02

Hallo! I have SuSE7.3 and the SuSEFirewall2 with 3 Interfaces, ppp0/eth0 192.168.0.99 --> DSL/Internet eth1 192.168.1.254 --> Network1 ---> pdc, webserver, mailserver, Clients eth2 192.168.2.254 --> Network2 ---> Clients My PDC is in Network1. But i want to use my PDC for Network2, too! I can´t ping any Machine Names. (except of the M$ Machines in the same subnet) So what do i have to change in my firewall config except of Point22? Do i need a wins or DNS to get the name broadcasts working? Cheers, Mario Ohnewald p.s. I hope i have explained it well enought!

ipsec and route
by ic_admin 15 May '02

15 May '02

Hi List, I have a problem with freeswan/ipsec and route since I installed SuSE 8.0 on my ISDN-Gateway: I added a new route before I start the software but this route didn't work when I start ipsec. And after I stop ipsec my route isn't available/visible anylonger. I have to restart the network to get back my old settings. This happens always I add a new route independent of the way I do this (with yast or the 'route add -net' command). Any ideas or has somebody the same problem? Thanks and regards Ruediger

libpcap - SuSE 7.3 different versions...
by Marcin Gryszczuk 14 May '02

14 May '02

Hi All.... I have just found out (by total accident) that libpcap on SuSE 7.3 distribution differs from that which is on suse ftp server in 7.3 distro director. In CD distribution I have 0.6.2-86 and on suse ftp is 0.6.2-100. Is it some security update or something? But I can not found any announcement about it and there is no libpcap update in SuSE 7.3 update directory as well. Am I missing something or is it common situation? Best regards to all...

> But his logs say his station was pinging the remote host, not > the otherway around. ok, i reread the original post by geordon vantassle. i'm sorry, i just scanned through it without reading the message carefully ... as far as i understand this post, there was a traceroute-attempt from 192.168.1.1. it reached 192.168.1.20 which then tried to ping 207.26.131.137. geordon also said, that a box wasn't alive at the time. i don't get which box wasn't alive - 192.168.1.20 or 207.26.131.137? geordon, if 192.168.1.20 wasn't alive and tried to ping 207.26.131.137, then don't panic but be carefull - maybe someone spoofed an ip-address and became part of your local net. if 207.26.131.137 wasn't alive, then there's just another box on the internet switched off ... do you know, who initiated the traceroute? regards, stefan

I have been seeing this since I started SFW2 and conect via ppp. Not sure why it's there, tried looking for clues as to why, who but found nothing meaningful. Figured it might be me and my isp (Well, I gotta think of something) Even tried to see if it time sync'd with anything going on with my box ie; sendmail, autofetch, etc. Usually I just copy error messages into google and find what I need to know but that didn't work this time. Any suggestions? I'd be happy just to stop seeing it reported but stopping it entirely, if feasible, would be cool also.

AW: [suse-security] smpppd

Hi, if smpppd is triggered via inetd, then there may be the possibilty to use tcpd to log and control, which source IP adresses could trigger smpppd. Just as an idea.

Mai 2002 13:29 An: suse-security(a)suse.com Betreff: [suse-security] smpppd Hi; is there any way to get informations about which app has triggered smpppd and how to xclude the one app from access but not the other? There's something that connects me to my ISP each time i log in and i don't want to follow the t-a-e-method. Besides that: it would be great for logging...
