I changed the code this way:
if [ ! -e
/usr/include/linux/.done_dl_patch_iptraf-netdevice-fix
]; then
bzcat $DL_DIR/src/iptraf-netdevice-fix.diff.bz2
| patch -p0 || exit 1
touch
/usr/include/linux/.done_dl_patch_iptraf-netdevice-fix
fi
It's already in CVS.

Dear Heiko, I tried to compile last development sources (from absolutely clean state in first pass) but iptraf is not compiling again. In log I found: > patching file /usr/include/linux/if_fddi.h > Reversed (or previously applied) patch detected! Assume -R? [n] > Apply anyway? [n] > Skipping patch. > 1 out of 1 hunk ignored -- saving rejects to file /usr/include/linux/if_fddi.h.rej Is it colision with other options? What I should check? Can You explain, what it mean?

Yep, I am beginning to suspect that this is not needed because I have VLANs...
I'll test this asap, but unfortunately it is offsite, with real users
connected :-)
Thanks,

I'm sorry, but is the line above really present in your dhcpd.conf file ?
I suppose the config should be similar the following:
--------------------------------------------------
max-lease-time 72000;
default-lease-time 60000;
subnet 192.168.123.0 netmask 255.255.255.0 {
range 192.168.123.50 192.168.123.100;
option broadcast-address 192.168.123.255;
option domain-name "ebac";
option routers 192.168.123.1;
}
subnet 10.0.0.0 netmask 255.255.0.0 {
range 10.0.0.100 10.0.0.200;
option broadcast-address 10.0.255.255;
option domain-name "lan";
option routers 10.0.0.1;
}
--------------------------------------------------

Correct, but if your vlans have different ip addressing schemes (I mean they are in different networks) you can just define 2 subnets in dhcpd.conf As far as I know dhcpd will serve the network from which it gets a request. -- Sincerely, Serge Leschinsky |

Hi again,
let me explain the problem I experience:
I have two ranges on my dhcp server, that should be distributed to clients on
the two vlans:
shared-network LAN {
subnet 192.168.123.0 netmask 255.255.255.0 {
range 192.168.123.50 192.168.123.100;
default-lease-time 60000;
max-lease-time 72000;
option broadcast-address 192.168.123.255;
option domain-name "ebac";
option routers 192.168.123.1;
}
subnet 10.0.0.0 netmask 255.255.0.0 {
range 10.0.0.100 10.0.0.200;
default-lease-time 60000;
max-lease-time 72000;
option broadcast-address 10.0.255.255;
option domain-name "lan";
option routers 10.0.0.1;
}
}
Both ranges are on two VLANs on the same physical NIC:
vlan100 Link encap:Ethernet HWaddr 00:10:F3:12:52:7D
inet addr:10.0.0.1 Bcast:10.255.255.255 Mask:255.255.0.0
vlan103 Link encap:Ethernet HWaddr 00:10:F3:12:52:7D
inet addr:192.168.123.1 Bcast:192.168.123.255 Mask:255.255.255.0
Unfortunately, hosts in both VLANs get addresses from the same pool....
Thanks for your input!
Frank

Frank, VLANs can be considered "virtual network cards" with separate IP subnets. A client would only be on one or the other VLAN, never on both at the same time. dhcpd should not have any issues with this nor would you need to reconfigure you clients. I run DL with VLANs myself. Or I might have completely misunderstood your email.... Regards, John Jore ________________________________________ From: dev...@li...

The vlan-tag is certainly stripped off the packet before it is passed to dhcpd, so dhcpd has no way of knowing which vlan the request came from.

You can figure out the snapshot behaviour, and thus files to backup, quite easily by doing 'ls -ltr' before and after lets say three successive snapshots. File timestamps rule here.. vswp file equals memory size of the VM. You shouldn't need to back it up. The 18:11 files below seem to make nice incremental backup set. Personally I try to make things as easy as possible. How? First time backup everything when the VM's power is off. Have a separate file of backed up files; "ls -l > somefile". Next backups will also be full backups, but excluding those very huge flat vmds files. As you see below, everything else is reasonable size, and backed up easily. Include "ls -l > somefile" in all backups. That way, too, you have a kind of time machine in your backups. All you need is the first backup and the last, or any other desired later backup. > lw3-000001-delta.vmdk 29-Feb-2008 18:11 16803840 > lw3-000001.vmdk 29-Feb-2008 18:09 215 > lw3-000003-delta.vmdk 29-Feb-2008 19:11 671115264 > lw3-000003.vmdk 29-Feb-2008 18:26 248 > lw3-499cb83e.vswp 29-Feb-2008 18:12 805306368 > lw3-Snapshot1.vmsn 29-Feb-2008 18:07 18482 > lw3-Snapshot2.vmsn 29-Feb-2008 18:11 806409071 > lw3-flat.vmdk 29-Feb-2008 16:54 12884901888 > lw3.nvram 29-Feb-2008 18:12 8684 > lw3.vmdk 29-Feb-2008 15:37 393 > lw3.vmsd 29-Feb-2008 18:11 815 > lw3.vmx 29-Feb-2008 18:23 1633 > lw3.vmxf 29-Feb-2008 15:27 258 > vmware-1.log 29-Feb-2008 16:54 121364 > vmware-2.log 29-Feb-2008 18:12 29777 > vmware.log 29-Feb-2008 19:06 56517 > > >> VMware offers Consolidated Backup addon, which is supposed to aid >> commercial backup software vendor products in doing (essentially) the >> same. > > IIRC, Consolidated Backup is not an option for 3i. > >> It is your choice to deside how you do it. > > Unless I choose 3i. :-) True again.. > - BS > > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Microsoft > Defy all challenges.

> I use a "Parallel Compile Jobs" of 2 or 3, depending how I feel on that day.
As a test, I compiled DL 1.3 on a VM. The difference in elapsed time
was not as great as I expected.
My desktop is a Intel 2.8 HT with 1GB memory. The compile took 8.6
hours ("time make unpack prepare build install iso dist").
I gave 4GB of memory and (4) 3.0Ghz Xeon CPU's to the Guest VM OS.
I increased "Parallel Compile Jobs" from 1 to 5 and timed it again.
With no other guests running, that timed compile took 7.75 hours.
I expected the VM to compile much faster.
FWIW, my desktop OS is Ubuntu 7.10, the VM OS is CentOS 5.1.
Now I'm curious what my home 2.33 Core 2 duo w/ SuSE 10.3 will do...

Hi ! I'm beginner in Linux. I use D-L since 2006, and works fine. I put version 1.2.14 two days ago. My internet provider ask a small aplication (IP-static, user and password) for connect. You can see connect method at http://acces.czone.ro/install_linux.html, and need PHP 5.1.2, and Zend 2.6.2 or 3.0.0 Also, he change TTL to 1, but I resolve that in firewall.rules. I use DL only for router. I launch the provider script under windows, behind router, and works till now. I tried to install PHP 5.1.2, but I didn't success. Could you implement the new version of PHP into the next release? |

I'd love to be wrong! :-) You are not wrong, but check this: http://www.vm-help.com/esx/esx3i/Import_RCLI_Appliance.html You are supposed to import a Debian based VM and execute it. It work with any ESX 3.5 edition. In that VM (RCLI, remote CLI) you can do management scripting etc. There are even things you can only do with this appliance/VM, like storage Vmotion. So even Virtual Center Windows guys/gals need this. >> In my mind VMware made a mistake by going to .net-only management for >> ESX3.

I really like 3i because of how small it is and the higher security (less to hack). I only have one server to install this on, so I need to connect one NIC on this server to our internal network and another NIC to our DMZ. I will only allow management from the internal network, and the guest OS's will only have access to one NIC or the other - never both. Because of that I want the most secure hypervisor possible. The possibility of a Linux kernel exploit someday allowing the DMZ to hack into ESX and get at our internal network concerns me.

Actually, the Linux, Service Console, is at that time running as a VM inside vmkernel. It kind of "turns the glass upside down" during startup.

For daily tasks, you get, with the full ESX, WebUI, which includes VM console, too. It reduces Windows requirement. At least somewhat. In my mind VMware made a mistake by going to .net-only management for ESX3. Sad mistake. > And the VMware infrastructure software (expensive features we're not > buying now) requires a standalone Windows server running a SQL-server or > Oracle database! Triple Yuck!!! You can use the built-in, or free editions of those, but yes, I understand.. Choosing Windows could only be a marketing decision.. Sad. Again.
