I would like to create a simple bash script, that will enable me to connect to a list of defined linux servers and execute a command there.
I looks like this code...
I am running the script under a regular user not root.
How shall I modify the script to go through all the servers?
i'm trying to build a web server but I keep having a problem. Everything loads fine until I get to the "Install base system" part of the installation and it puts up a red screen warning me that the install has failed. My uncle gave me his ubuntu discs and even some different hard drives, but I keep getting the same problem at the same point of the installation. Here is the rundown of everything i did.
System #1 -
ASUS P5G41-M m/b with 4GB memory
Intel Core 2 quad q9300 cpu
two western digital 640GB hard drives
I was testing it out to run a raid 1 just to learn how to make a software raid array. its my first try at making a raid array. The first time i used ubuntu server 10.04 32bit and the system failed at the install base system point. I then used boot n nuke to clean the drives and tried 10.04 64bit. it failed at the same exact point. my uncle gave me 2 western digital 1.0TB hard drives and I tried again. I got the same results. At that point i gave all the hardware back to my uncle and he gave me a server board to try out because he bought it and hasnt touched it. so I built a second system.

I am trying to sync or copy some files from my local home directory to my external passport drive. My passport drive has been acting weird , I was having a hard time mounting it, but finally I did it. It was mounted using FAT (for compatibility reasons)Now I am trying to copy the files but in a smart way, using this script with --modify-window switch.Is that a bug? Is the --modify-window switch missing on Ubuntu or maybe different?

The details is below:

We have pcA, pcB (using Linux OS kernel 2.6.26.5) connect together. We need to modify the source code of kernel at B in order to if A sends the packets with destination IP address as C, pcB still receives this packet and send to transport layer (that means, it bypass the routing lookup process at kernel).
The solution I used as the following code...

From a Windows client, I can connect to it without any login (I enabled anonymous) and I can download from it, but I am unable to modify it or upload files. Unless there is a better way to transfer files between the computers, how can I enable writing on the FTP server?
View 3 Replies View RelatedI have a multi user system for my roommates and myself that has separate folders for each of us. I've got user authentication working with samba, but unless I set every file and folder readable/writeable by all users, I can't browse it or edit the files.This isn't ideal as the shares are open to other users access, so I'm hoping there's a way to keep folders at 750 and files at 660 while allowing samba users to browse, delete and edit.Also, the samba share is actually a mounted NFS share from another server. Both the NFS server and the Samba server have the same users/uid's. When a file is created from a Windows host via the Samba client, the NFS server's permissions do show that the correct user owns the files, but since the files aren't mode 666 but 640 I can't edit or delete the file.

1. Type: LoadModule rewrite_module /libexec/mod_rewrite.so
2. Find the <VirtualHost> section in the httpd.conf file.
3. Find a line in the <VirtualHost> section of the httpd.conf that looks like this: AllowOverride None
3. Replace that line with this line: AllowOverride FileInfo Options
4. On a new line, type ServerAlias *.[URL].
5. Save the httpd.conf file and close it.
I have a few ubuntu servers which have samba shares on the network and for the most part have had little trouble with them. Recently we purchased a few iMac's for one of our deptartments and, while we're able to access the shares, all the files on them are read-only and we are unable to delete/modify files using the iMacs. This is not an issue with any of our windows machines (W2K, WinXP, Vista).

Fedora Core 14 On Gnome 2.32.0
(Linux xxxxx 2.6.35.6-45.fc14.i686 #1 SMP Mon Oct 18 23:56:17 UTC 2010 i686 i686 i386 GNU/Linux)
We have a small cluster of 20 HP systems, all running CentOS 5.3 in an NFS-root environment. Half are quad-socket, quad-core Xeon E7340 @ 2.40GHz (total 16 cores), the other half are 8-socket, quad-core Opteron 8354 (total 32 cores). All systems have a Mellanox Infiniband adapter ("Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE] (rev a0)")
With kernel 2.6.18-128.1.6.el5, infiniband works fine on all systems.
With the update to kernel 2.6.18-164.11.1.el5 (and both types of node running the same NFS-root image), the 16-core Xeons still work fine. Infiniband no longer works on the 32-core Opterons. Specifically, either the ib0 interface fails to appear, or it does appear but when configured with an IP address, doesn't actually work. In either case, loading the IB kernel modules takes a long time, but I haven't instrumented the load script yet to see which module, if any, is at fault. More errors listed below.
However, if I tweak the BIOS of the 32-core systems to reduce the per-socket core count to 2 (so effectively 8-socket, dual-core, down to a total of 16 available cores), Infiniband starts working again. Putting it back to 32-cores makes it fail. Booting the older kernel makes it work again. In summary: old kernel, IB works on all systems. Newer kernel, IB only works on 16-core systems.
Updating the IB firmware from 2.5.0 to 2.7.0 (latest available) doesn't help. I also did a full 'yum update' to make sure that libmlx4, openibd all other associated packages were up-to-date. Doesn't help either.
Some errors that appear on 32-core nodes:
ib_query_port failed (-16) for mlx4_0
ib_query_port failed (-16) for mlx4_0
mlx4_core 0000:04:00.0: SW2HW_MPT failed (-16)

My first post here. I've been using Ubuntu to run our internal mail server for a while now on Ubuntu server 9.04 and ISPconfig 2. I've read a lot of threads on poeple that have difficulty connecting to their server using SSH from outside the LAN and it is not the same problem I have. Well, not entirely the same.
My problem is that my authentication fails from outside the LAn, but I can connect to the SSH port from outside my LAN. The other threads pointed towards checking the router port forwarding etc, but I can see my SSH log in asking for my username and password. So, at this stage I know the port forwarding worked, otherwise I wouldn't even see the log in prompt.
Has anyone see this before where you can connect, but the authentication fails? I can use the correct username and password from inside the LAN, but using the same credentials from outside fails.

We are trying to consolidate some servers to run as virtual machines on our F13 host.After booting into SystemRescueCD, we take a dd of /dev/sda (we initially did a dd of sda1 before realizing our error)We transferred this image (EDI.img) to our F13 VM host. and created a new virtual machine using the graphical Virtual Machine Manager using "import an existing disk image" and the same EDI.img file as the storage volume.
Unable to boot, I've done much googling to find the registry entries of MigrateIDE.reg - which I've manually added to the image's registry via chntpw -e /mnt/windows/WINDOWS/system32/config/system.Another forum's posting advised to boot from the XP iso and allow this installation process to "repair" the existing installation. I'm still sitting at a blank screen with minimal CPU activity. Can anyone point me in the right direction on how to migrate a physical XP machine to be a virtual machine running under F13?

How to resolve this apache2 problem I keep getting, I have installed a debian LAMP server with ispconfig3 and everytime I reboot apache fails to start, I don't know and I have done some research but nothing seems to work, which leads me to reinstall everything from scratch again, I think I have reinstalled at least 10x or more.
When ever I reboot I get the following error
Code:

Attempting to install 10.04 Server on an IBM Series X 232 server. Its an old server with dual p III's, 4 small drives and an adaptec controller with a RAID 5 array. The server is currently running CentOS 5.5.
The CD I am installing from is known good. I verified it after I wrote it and verified it again during the install process. The system boots from the CD, I accept the defaults, then it fails at "adding additional components".
This morning my system has a problem which is beyond my ability to understand: Firstly, the system does not boot automatically, after a fixed delay, from the grub menu. I have to press 'enter' against a chosen boot option. Secondly boot then fails. A lot of messages flash past the screen (which appear to be a trace) and end showing the following (partial example):
Code:
Killed
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn't have requested /sbin/init.
No init found. Try passing init= bootarg.
at this stage I can move around the directory structure using 'cd', but no other commands seem to work.I tried the recovery boot option - same result. Is this a symptom that my boot drive has failed? No, that can't be true, or I would not be able to see the grub menu, would I? I can't find a similar situation after a Google search; what recovery procedure I should use? Correction: I must have had brain fade: I see there is quite a long thread on this very topic on the forum. I'm going to examine that first before I ask for more help.
I have a freshly installed, updated Fedora 11 installation for which the VMWare Tools fails. It can't compile what it needs, either. It's running under ESXi 3.x.
