Router hacks?
by Paul W. Abrahams 20 Dec '05

20 Dec '05

Are there any known instances of people hacking into Linksys/Netgear/D-Link routers from the outside where the router owner has taken two elementary precautions: not enabling external access and changing the password? In fact, are there instances of hacking into the default configuration, which doesn't enable external access but does use a well-known password? I posed this question in another thread but I think it deserves a thread of its own. Paul

Drive failure on Suse 8 server-Raid 5
by Dana Jaeger 20 Dec '05

20 Dec '05

Hi, I have a drive failure on a Dell server 2650 running Raid 5. It has 3x26 GB hard drives. OS is SLES 8 kernel 2.4.21-241-smp. I don't know the raid driver. What process should I follow to replace this drive?

First there is the Nat box, then at least a software firewall, on all the machines. I have also set up a dmz to a "test" network with it's own firewall settings, for learning. While you can have firewalls with a similar problem (aka if someone found a flaw in the tcp/ip stack) you are a little safer by having the software run on different hardware.

Re: [SLE] Large File Transfer Problems

No insult taken and I am not a newbie by any measure. My point was that I can work around the problem with wget and ftp get, depending on the source of the file. I have have experienced the SMB (Samba) problem with SuSE 10.0 and ArkLinux 2005.2 where the file supposedly transfers but just sits there at 100% and continues transfering, never ends, and the MD5 checksum is in correct for the file if I force the process to stop. ----- Original Message ----- From: "Michael W Cocke" <cocke(a)catherders.com> To: suse-linux-e(a)suse.com Subject: Re: [SLE] Large File Transfer Problems Date: Tue, 20 Dec 2005 06:36:08 -0500 > > On Mon, 19 Dec 2005 16:57:57 -0700, you wrote: > > > I have been having some challenges downloading large files such > > as DVD iso > 2 GB.

can't ping to gateway
by Daniel Bauer 20 Dec '05

20 Dec '05

Hello, good evening Just installed opensuse succcessful (standard kde install, no changes in software selection). Installed network card with Yast, stopped firewall (clicked "start manual" and stopped it). Everything seems normal, but I don't get any connection to outside. Ping to my gateway doesn't work ("destination host unreachable"). I just entered all the same values for local ip, gateway, name-server... as in Suse 9 on same machine. Ping to local host works. I don't know which info you need, here's what is displayed when typing "ifconfig": eth0 Link encap:Ethernet HWaddr 00:08:A1:35:BF:BC inet addr:192.168.2.2 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::208:a1ff:fe35:bfbc/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:38 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1957 (1.9 Kb) TX bytes:2462 (2.4 Kb) Interrupt:9 Base address:0xb400 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:102 errors:0 dropped:0 overruns:0 frame:0 TX packets:102 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6880 (6.7 Kb) TX bytes:6880 (6.7 Kb) this is (apart from the no. of packets/bytes) exactly the same as in Suse 9. "route -n" gives the following: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 eth0 where I am wondering about the "169.254.0.0"-line, because I never typed in such a ip-number anywhere. On Suse 9 this would give me only 2 lines (192... and 0.0.0.0). Should I send the /var/log/messages of my last Suse10 session? In case: Copy text in mail or attach? What did I forget to make my network connection work? Thanks for any help. Daniel

Firefox as web browser for kmail
by Paul W. Abrahams 20 Dec '05

20 Dec '05

Recently I unearthed the solution to the problem of getting Firefox to invoke kmail for mailto: links. Now I'm confronted with the inverse problem: getting kmail to invoke Firefox to follow links embedded in email messages. Getting kmail to call Firefox is easy: the Component Chooser in the KDE Control Center. What's hard is getting Firefox to open the link. Neither Konqueror nor Mozilla has this problem. If I set the browser in the Component Chooser to mozilla or to konqueror, the cited browser is opened and displays the contents of the link. But with firefox, the browser opens an empty page. To understand this better, I issued these three commands from a shell: konqueror http://www.suse.com mozilla http://www.suse.com firefox http://www.suse.com As expected, the first two opened up the SuSE web page; the third opened a blank page. There have been a number of postings on this subject, explaining (correctly) how to make Firefox the default browser. But I can find nothing about how to get it to open the link. I looked at the firefox shell script that eventually causes firefox-bin to be invoked, and it has no references to $1 except in a function. Since I can find no one who's asked about this, I'm wondering if there was a change of behavior when Firefox was upgraded to version 1.5. So has anyone gotten this to work? If so, what's the trick?

Loading SuSE 10.0 on Dell C800
by egearing＠gmail.com 20 Dec '05

20 Dec '05

Anyone ever try loading SuSE 10.0 onto a Dell Latitude C800? I've tried, but all I get is a black screen when x loads. I think the reason is it sees the graphics card as an ATI Rage 128 when it really is an ATI Rage Mobility M4 16M. Is there anyway to get it configured porperly? Two other Linux operating systems load X OK. They are Mandriva LE 2005 w/ a generic VESA driver and also Kubuntu Linux loads X properly. Any help would be appreciated. I'm also trying to get a Belkin F5D7010 wireless NIC to work with those but no luck either so I'm hoping SuSE 10.0 will help me solve that problem. Thanks, Evan

APT, SMART or just RPM?
by Shibu Basheer 20 Dec '05

20 Dec '05

Hi, I am new to APT or SMART. What are their advantages over RPM? Do they integrate with yast? Also, which should I be using apt, or smart? How does apt know how to upgrade already installed rpm packages? Sorry for all the questions, but please someone help me choose the best package manager. Thanks, SB.

Hi suse users and developers, Im new to linux world and since suse is offering excellent GUI support Im using SUSE 10 on my intel pc box.
