Don't try to use ping to test your QEMU network configuration! Regular user running VM does not have enough privileges to send ICMP packets.

Internet Access Problem
I am running Bullseye and attempting to use QEMU/KVM virt-manager, on the computers on my LAN rather than Oracle VM VirtualBox. I particularly would like to be able to run Windows 10 as there in one application that I need for my molecular modeling research that is not available for Linux. I followed the How To (HowTo.txt, attached) without any warning or error messages. However, when I pinged yahoo.com. I got the result: Reply from 169.234.75.136: Destination host unreachable. It is my understanding the internet should be reachable from Windows 10 from the default connection. The default virt-manger xml file and the host i pa results are also attached. I would appreciate any sort of insight as to what might have gone wrong. Thanks in advance. -- Stephen P.

Internet access problem with ppp(oe)
Hi, Problems with internet connection. Neither browsers nor apt cannot access internet right after booting up to X. After booting up there's two pppd-processes, which need to be killed, and then only after running "pon dsl-provider" (prints "Plugin rp-pppoe.so loaded") internet connection works. I'm quite green with debian and with linux, so that workaround was found simply by an accident.. The problem was evident right after Etch installation (netinst dvd-image). Network manager (an icon the side panel) notified that there was a network connection, and that there were updates available, but still the browsers couldn't access the web. "ps x | grep ppp" shows 3736 ?Ss 0:00 /usr/sbin/pppd call provider 4587 ?Ss 0:00 /usr/sbin/pppd call dsl-provider 5227 pts/1S+ 0:00 grep ppp Running etch, vdsl-modem, ppp confed with pppoeconf. Have two entries in /etc/ppp/peers/. (and don't know if both of them should be there) Also, Firestarter is running and showing eth0 (type is ethernet) and ppp0 (type is internet) and ppp1 (type is dialup). -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Internet access problem with Debian Sarge + BSNL Dataone
Hi, Kindly help me get my first browsing experience in Debian linux. I have tried various list-archives recommended by Google still have not been able to get around fixing this. Email below is rather long. I have explained my installation and shown the logs before asking my questions at the bottom. I have installed Debian GNU/Linux, Sarge 3.1r0a on my PC along with Kernel version 2.6 686. I also have the dataone broadband service from BSNL (in bangalore, INDIA). I logged in as root and started ADSL/pppoe configuration as root (/usr/sbin/pppoeconf) and answered the questions. Entered user-name and password - but I didn't get a question for which I could enter the DNS server names in response.. To clarify further, I did not additionally install rp/pppoe or any other software on top of the installation. eth0 contains a LAN card. This was detected during installation and the driver was automatically loaded. The ethernet connection is active and ifconfig on restart/startup is as follows: eth0 Link encap:Ethernet HWaddr 00:05:5D:4B:1E:85 inet addr:192.168.1.34 Bcast: 192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::205:5dff:fe4b:1e85/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:140 errors:0 dropped:0 overruns:0 frame:0 TX packets:175 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:11877 (11.5 KiB) TX bytes:15003 (14.6 KiB) Interrupt:209 Base address:0xc400 When I run pon and then plog I get the following output. plog output (copy-pasted from /var/log/syslog) Dec 23 21:57:23 localhost pppd[4727]: Plugin rp-pppoe.so loaded.

The primary reported in the log output doesn't ring a bell at all... After the first time I ran pon the file /etc/resolv.conf contained the primary and the secondary nameserver addresses as per the log above (218.248.255.145 & 61.1.96.69). When these were edited to be 61.1.96.69 & 61.1.96.71 (the correct values supplied by ISP), the log still showed the same output and nameservers were the same (they get reset!). Some other information... debian:~# route -n Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 debian:~# ping 218.248.255.145 PING 218.248.255.145 ( 218.248.255.145) 56(84) bytes of data.

If not, then how to correct this problem and verify if it has connected properly ? Once pppoe connects is there something extra that needs to be done to access the web from my desktop ?

I had problems connecting linux to iprimus dialup routers, and was informed by iprimus that the "do not support linux". The problems I had were constantly breaking dialup connections and problems establishing reasonably long lasting TCP connections (no RST or FIN packets. The stream just stopped). I would suggest turning on debugging on your PPP connection. Go pppconfig and under your connection choose advanced, and then switch debugging on. >From the debug info in syslog I saw constant CCP negotiation errors and problems (Compression Control Protocol). I fixed this by forcing off BSD and deflate compression on the connection. Edit /etc/ppp/options and add in these lines bsdcomp 0 deflate 0 noccp restart ppp and make sure that the CCP errors no longer appear in your ppp debug output. Although this removes the compression, it won't slow your link to much as you think as the modems will still have their LAP-M or whatever its called. Basically when iprimus says "we don't support linux" they mean, "we don't debug our dialup routers, if windows dials OK, then its OK, right!" Let us know how you go. Kind Regards Crispin Wellington

Hello Debian, I have recently installed Debian onto an old P75 of mine and am using it as an internet sharing server I am using a modem connection and using firewalling with masquerading I am also running exim and squid the problem is that it connects and masquerades without any problems clients can browse the internet and send emails but for no apparent reason HTTP access becomes unavailable after awhile it seems to occur after using email but not always I can ping FQDN without problems i.e. www.yahoo.com but can not browse web sites this is also the case from the server using lynx it hangs "waiting for response" is there any clues as to the cause of this problems I would appreciate any assistance thank you Darren Walker mailto:[EMAIL PROTECTED] http://home.iprimus.com.au/drwalker
