General :: Cut And Paste Boot Commands From PC To ILO Remote Console?
Jul 1, 2011I downloaded rhel 5.5 CD 1 iso to my PC, and used it as a virtual CD-ROM to kickstart HP DL380 G4.Here is my questions:
1. how can I cut and paste boot commands (very long strings) from my PC to iLO remote console?
2. is there anyway I can get "boot prompt" by ssh to iLo's IP?
3. after kickstart, I want to eject the virtual CD-ROM / media, I have tried the following method in the kickstart profile, but all failed, after reboot, it still boot from the virtual CD-ROM. So how can I reject the virtual CD-ROM for rhel 5.5 kickstart?
General :: Removing Previously Type Commands At A Remote Server?
Aug 7, 2010I am ssh'ing into a remote server and then su'ing to root.The problem is that sometimes, I have not paid enough attention to the console message, and I have accidentally typed in the root password at the command prompt (when for example, I had failed to provide the root password correctly the first time - so su prompt went away).
I remember reading somewhere that a history of commands typed at the console is kept somewhere.I have 3 sub questions
Where (which folder) is the file stored?
Can I edit that file and remove the root password from it?
Being the paranoid person that I am, I wonder if there is a more secure way of logging into my server - other than ssh (or am I being TOO paranoid?)
My server is running a headless Ubuntu 10.0.4

Ubuntu :: Ssh Commands Execute Locally Instead Of On The Remote Computer?
Jul 12, 2010I can ssh to the remote computer OK, but the commands execute on the local machine, not the remote machine as they should. After much frustration I did the following hoping to clear the problem. I turned off all machines on my LAN, the hub and the router. I then rebooted everything in the reverse sequence - cable modem, router, hub, and then the computers.Then I reinstalled ssh on both machines.
sudo apt-get purge openssh-server openssh-client
sudo apt-get install openssh-server openssh-client
sshd in now running and port 22 shows on both machines. However the problem persists.
Software :: Execute Script To Run Commands On Remote Server
Jan 1, 2010I have an immutable script on server A, it executes a maintenance command on the remote servers where elevated privileges are needed. I want the developers on server A to execute the script and run it without being prompted for a password. The script contains scp root@serverB and ssh 'root@serverB', if run as root it runs great since I am using ssh keys. However, as regular users they are prompted for a password. If I do created their group on server B...etc and give the group sudo it would still ask for passwords right? Can I overcome this?

I'd like to be able to have those scripted commands available in the history file when I log back in interactively.

General :: Sync Server And Client - Wait Over A Minute For The Changes To Be Downloaded?
Oct 17, 2010I work as a part-time consultant developing webpages, both back end and front end.When developing a back end application I'm using a server running ubuntu server edition to host the application while I'm developing it.The problem comes when I want to upload my changes to the server, now I'm using Dropbox both on the client and the server, the problem is that sometimes I have to wait over a minute for the changes to be downloaded (when I'm working out-of-home that is) so I'm looking for a better alternative. My options seems to be:Some open source version of dropbox which syncs directly to my server (haven't found anyting that sounds viable though)
Mount my server via some protocol (NFS, SSHFS etc)
Push changes manually via FTP, git, svn or something else
I'd like the sync to be as transparent as possible, meaning I'd like to do as little manual work as possible.The client I'd like to connect runs either OSX or Ubuntu.The ultimate solution would be to use NFS + VPN though that would be alot of work to set up and also I don't like the security in NFS (matching UID's doesn't seem very secure to me)

Jul 1, 2011I've installed both Fedora 15 x64 and Fedora 14 x64 on an HP Proliant DL380 G4 with the HP SmartArray SCSI controller, 2x146GB UW320 SCSI drives.The server was running RH v4 with a hardware RAID 1 with uptime of 400+ days with no issues.I broke the HW RAID and made 2x volumes and software RAID. I have another identical server with 4x 146GB UW320 SCSI drives with Fedora 12 x64 and SW RAID, so I figured 14/15 should be the same process.What happens is the server runs great for a while, but when I leave it for a few hours, it becomes non-responsive. I've re-installed 15 and 14 multiple times now and also installed NRPE, which shows load increasing to the point to where the server is non-responsive. It hits high load levels (as reported by NRPE). The load levels appear to be increasing over time. Such as last night:
log off at midnight, load average 0/0/0
2:03 am - WARNING - load average: 9.91, 8.85, 6.75
3:03 am - WARNING - load average: 16.91, 15.86, 14.47

View 2 Replies View RelatedUbuntu Servers :: High I/O Wait After Every Reboot?
May 19, 2010The Machine
Core 2 Duo E4600
2GB DDR2 RAM (1 stick)
Intel ICH10R based motherboard (tried an ICH9R aswell)
4-port SATA controller (PCI Sil 3114)
O/S: Ubuntu Desktop x64 10.04 LTS (using 'desktop' because I like having a remote desktop)
The Storage Setup Disks: Assorted selection of 9 disk. 750GB, 1000GB and 1500GB Seagate and Western Digital disks. The disks are joined through a standard LVM2 configuration. I don't know the LVM term, but normally you'd call it a JBOD setup. On that LVM device, I've put a cryptsetup device, made with the LUKS tools (aes-xts-plain 256) On the cryptsetup device, I've created and mounted an EXT4 partition.
All in all, a completely standard LVM2 and LUKS setup, running EXT4. After a reboot, I proceed to unlock my cryptsetup encryption device, and then mount the EXT4 partition. All is well, the mount is accessible and everything looks fine. I then try to send a file to the mount, via Samba. After a few hundred MB written, the I/O wait goes berserk. It stays at 50% (dual core setup remember). The system becomes unresponsive to network commands (can't browse samba) for about 5-10 minutes. When it finally responds, the I/O wait is gone and everything is now fine. I can write and read hundreds of GB's of data without any issues at all. I can benchmark and stress all disks perfectly fine and no logs are showing disk errors.
I tried monitoring my disks with 'iostat -d 2' while the I/O wait was happening, and there is some slight Blk_read/s activity on 1 disk at a time. First for example /dev/sda is showing a little Blk_read/s acitivty, then it jumps to the next disk, and when every disk has show that slight Blk_read/s activity (500-800 or so) the problem is gone and the I/O wait is no more. I've tried changing motherboards, switching disks around on the controllers, checking individual disks, replacing disks and I've tried different versions of Ubuntu. The problem however persists. I could see it being a network issue, possibly a driver issue. But since the NIC is a standard RTL8111 on-board it seems unlike that the problem wouldn't be more widespread since this NIC is litterally being used everywhere. I did change my motherboard, so a faulty NIC seems unlikely twice in a row.

Apr 30, 2011I applied all updates to my Kubuntu 10.04 installation, and shutdown and went to bed. Booted up this morning and found:
[code]...
This error is returned if the module load command is used before loading a Multiboot kernel. It only makes sense in this case anyway, as GRUB has no idea how to communicate the presence of location of such modules to a non-Multiboot-aware kernel. lets re-install GRUB. So I booted up my live CD, and ran:
sudo GRUB
find /boot/grub/stage1
root (hd0,0)
setup (hd0)
quit
sudo shutdown -r now
Same error. So I started looking around, and most complaints of this particular error seem to be dual boot environments, which I found rather odd, as I have never dual booted this machine.....

View 6 Replies View RelatedProgramming :: C++ Cin Doesn't Wait For Input By Operator
Jan 4, 2010I am trying to learn C++.I implemented a simple archive program, and I am in a situation in which the user is prompted by a menu to make a choice.So I have some cout instruction to illustrate the possible choices and then
int choice;
cin>>choice;
and everything works fine.I introduced this code in a "while" loop that checks wether the choice made by the user is valid or not:
bool check=true;
int choice;
while(check)
{
cin>>choice;
if(the choice is valid) {...;check=false}
else cout<<"please make an other choice"
}
What is happening is that if by mistake the user introduces a character in place of a number, the loop repeats indefinitely because the program, when it get to the "cin" instruction, does not pauses to wait for a new input.
