CentOS 5 :: Create ECDSA On Centos 5.6 Final?
Jul 22, 2011
I have a project needing ecdsa and ec support in Openssl. Unfortunatly the openssl in CentOS 5.6 Final are built without
this functionality. As my experience with CentOS are a little on the fresh side, I would like to know my options in this case.
How I can create key pair as ecdsa?
After I upgrade openssh until version 5.8p1, It's not work on command ssh-keygen -t ecdsa 256, I got feedback "unknown key type ecdsa
"...
What I have suppose to do? when I use openssl new update my server can't work properly again, so I decided to installation again.

I've used ssh for a long time, but recently I set up a new server on my LAN. Often when I try to connect to it I get a message like so:
Code:
Warning: the ECDSA host key for '<snip>' differs from the key for the IP address '<snip>' Offending key for IP in /home/<snip>/.ssh/known_hosts:14 Matching host key in /home/<snip>/.ssh/known_hosts:12 Are you sure you want to continue connecting (yes/no)? What is weird is that, in the known_hosts file, the entry for the ip address (line 14) is a "ssh-rsa" type, but the entry for the hostname is a "ecdsa-sha2-nistp256", even though they both connect to the same server. What is going on here?

I would like to install PostgreSQL 8.5 from this link [URL], but it complains that it needs rpm-4.6.0 as dependency. It seems that CentOS does not support rpm with version bigger than 4.2.2, or am I wrong?

We have a linux server (centos 5.2 final), with postfix smtp server, webmin, usermin and sugar crm
We need to backup all the data, and then perform a restore on a clean machine, without any OS installed yet.
I look into many pages that says that doing a backup on linux it's as easy as pack all the files in a .TAR file. Unpacking the tar will restore the system to it's original state. Also, i'm confused because if we perform a backup and mysql has active connections, perhaps the database would be inconsistent or corrupted. In the restore step, do i need a live CD in order to boot up linux command prompt? �Can it be from any linux version, or only centos version?

I'm trying to create a CentOS based liveCD that mounts a NFS share and executes one script there. The NFS never mounts altough while logged I can mount it with the very same command that I use in the KS.
In the %post I have :
%post --log=/tmp/post.log --erroronfail
mkdir /mnt/nfs
mount -o nolock 10.23.1.1:/csc/RemoteHome /mnt/nfs
I added the --log in order to debug, but nothing is written in /tmp/post.log. I tried redirection on the mount command with >> /tmp/debug.log but this is not written. Maybe during the post sequence /tmp is RO ? Anyway, I tried with ifup lo, service portmap start in the %post, but doesnt change (I even have a service : command not found in the live cd creator output).
Here is the remainder of the KS :
lang en_US.UTF-8
keyboard us
timezone US/Eastern
[Code]...

I installed the latest CentOS 5.5 in my PC. I added some public domain projects on it. Now how can I make another boot-able CentOS iso file with all the new projects I just added? In the other words, I try to create a boot-able CD with the CentOS and all the projects on it.

Problems with xen 3.1.2 creating and installing domU CentOS 5.5 I am trying to do a virt-install --prompt --paravirt, and the install error out while trying to download install RPMs. I have googled for xen centos virt-install and various permutations. I have found similar howtos for 5.4 and 5.3, but they resulted in the same outcome. I did find several posts with similar issues, but no solution was posted.[URL]..

I've got a remote server running CentOS and I require a new user account who would have access to sftp & ssh functions.I've got a bit of a problem creating the user since whenever I try to login with the new account through ssh (putty) I keep getting access denied.I've made different accounts with userids above /below 500; even though I'm a complete noob so no idea how I'm supposed to go about this.

I'm trying to create some PHP extensions. I have installed php-devel as well as the other preqs I thought were required. However I'm not able to find ext_skel. The file README.EXT_SKEL was installed, but not the actual program (find / -name ext_skel). My understanding was ext_skel was installed with php-devel. I know it is in the source code, but I'm not sure where to get the source for PHP 5.1.6 for my version of CentOS.
I'm running linux 5.3
2.6.18-128.1.10.el5

I am using CentOS 5.4 dvd to install. What I need is to be able to create a partition with GUI (it's druid, maybe) without formatting it. I remeber once there was a check into creating new partition form, but maybe i am confusing with fedora or other distros. Is there a way to complete job using GUI or should i create partitions: / /boot and swap with GUI and the others with fdsik?

I have a process that seems to be unexpectadly quitting. Checking the messages log I could not find anything out of the ordinary. Would anyone here know how to make a process unkillable or lock a process somehow? I read information on doing this by making a looped iso, however the process im starting requires to be able to read/write to the files in the iso so this is not going to work. For now I just niced the process to top priority but I dont really think that will work. This process is a voice server so I dont want people getting discouraged that the server will not stay up and decide not to use the free service im offering.
Would anyone else have any insight as to what I can do? Im not new to linux but im not familiar enough with how every command is used, so if at all possible please give me the commands that need to be executed.

I would like to create a customized CentOS server, or it will serve me as a server (postfis) postfixadmin, Hylafax, webmail (Roundcube for example) and may be I would integrate suger crm.
If I create it all this server and it runs perfectly. my goal is I create a compilation or for example I install this distrubution and wonder just some configuration (eg IP address or the time just) knowing that by the end of the installation I find hylafax, postfix , and all AC roundecube install it remains for me to set them up! Taking the example of Elastix cd: www.elastix.org/ or it can make all AC (but its main role is the PABX).
