Hi, Running: Freebsd 6.0 I am wondering if it is possible to have acces to loopback ip in a jail. I currently have a server running a jail. In the jail, there is a database and a web server. I would like to be able to have the database only bind on a loopback address and not on the jail's ip. Can this be done and how? Thanks -Cyril ____________________________...

I'm not sure what 'iscsi loopback' even means. iSCSI is used to mount a virtual block device hosted on another system (initiator mode) or to share a virtual block device (target mode), while loopback is used to mount a local file as a device, such as an .iso image o...

Hi, I am new to DTrace. Want to capture (for specific port #s) the loopback interface (lo0) tcp message flow with the complete message body. Is this possible with DTrace? Are any examples available?

Hello List, After demystifying the cause for my /sbin/ifup-local not being executed by network scripts for an Ethernet interface (don't let NetworkManager control it or ifup-local won't be executed)... ... I have a question with hopefully a simple answer: I placed an alias/description on my interface during testing and now I want to remove it. But when I try to remove it, I'm either

Hello-- I'm trying to use extlinux to make a bootable disk image, but I've hit a wall. I've got a partitioned hard disk image with one ext2 partition in it. I've mounted the partition through a block loopback device (/dev/loop1 on the host) and chrooted into it in order to run extlinux. Within the chroot environment, /etc/mtab says: /dev/hda1 / ext2 rw 0 0 ...and within the chroot, /dev/hda1 is a device node for the loopback. But when I run extlinux, it complains: extlinux: cannot find device f...

Hi, I''m experiencing some troubles with an application in a VM (domain-1) which needs to connect too itself via the loopback interface. It seems that the connection process hang during the TCP handshake. I have a running web server in this VM which run perfectly. Logged in Domain-1, i''ve tried to reach the webserver with telnet but the same problem happens. Even pinging the loopback interface give me en error (...

I want tinc to listen locally on loopback, so that port 655 is not exposed on any system interfaces. Can't tinc make outbound connections when listening on loopback? I can't see any reason why it should. This system will never have other tinc daemons connect to it, it will only ever connect to other tinc daemons in order to establi...

Package: xen-utils-3.2-1 Version: 3.2.1-2 Severity: normal When a DomU is defined as using a file: device the loopback driver will be used to make it appear to be a regular block device. The loopback driver will by default only support 8 nodes so this is a limited resource. http://etbe.coker.com.au/2008/10/22/kernel-issues-with-debian-xen-and-centos-kernels/ If there is a problem that prevents correctly allocati...

.. what is? fellow centosians. how to you mount your loopback targets? I'm trying lvm backstore, I was hoping I would do it with uuid, but it's exposed more than once and how would kernel decide which device to use I don't know. thanks

Is there an existing RFE for, what I''ll wrongly call, "recursively visable snapshots"? That is, .zfs in directories other than the dataset root. Frankly, I don''t need it available in all directories, although it''d be nice, but I do have a need for making it visiable 1 dir down from the dataset root. The problem is that while ZFS and Zones work smoothly

Hi to the ML. I''m new to VLAN configuration, and combining it to XEN is a bit difficult. I want to use VLAN because it''s possible to "arping" from a domU to an other, and VLAN looks like; the only solution to prevent that. May be I''m wrong if someone got a solution, I may be interrested. I''ve also tryed ebtables, but nothing to prevent arp
