If you tried installing RHEL 9 on Synology VMM , you probably hit this nightmare: Installer freezes waiting for multipath siblings of sda Kernel panic “Unable to mount root fs” Black screen forever I spent hours figuring this out. This guide will save you that pain and help you create a Golden Template so you only install once and clone forever. Why RHEL Fails on Synology VMM Synology VMM uses simplified KVM virtualization. RHEL assumes enterprise SAN storage and enables multipath disk detection by default. Synology presents a single virtual disk → RHEL thinks it’s a SAN disk → installer waits forever for extra disk paths → boot fails. The fix is simple once you know it. Step 1 — Create the VM with Correct Settings Create a new VM in Synology Virtual Machine Manager . Use these settings: General OS Type: Linux Version: Other Linux CPU & Memory CPU: 2 vCPU minimum (4 recommended) RAM: 4 GB minimum (8 GB ideal) Boot Mode (IMPORTANT) Use BIOS / Legac...

First of all the following value has to be unique to each install of Sterling Integrator. If you accidentally used shared location for cluster installation your second node installation not going to work. So here is how we can fix this. 1. Go to user home and move $USERHOME$/IBM/IBMSHARED to new local location. 2. Update the reference in  /home/user/var/ibm/InstallationManager/installRegistry.xml           That's it. This will fix First node IBMSHARED location and we can proceed with second node installation. How to verify? 1. Go to InstallManager tools     cd /InstallationManager/IM_Linux/tools  2. ./imcl listInstalledPackages -verbose Validate the output something like below, [Shared] Shared resources directory: /opt/ibm/IBMIMShared [Package group] Name: Sterling Integrator Installation directory: /opt/ibm/sfg Translations: Architecture: 64-bit [Package] Name: IBM Sterling B2B Integrator (com.ibm.sterling.in...

Some of the IBM Sterling B2B Integrator(SI) customers wants to avoid SSH handshake using CBC Cipher as it is vulnerable. The link  http://www.kb.cert.org/vuls/id/958563  explains that CBC Ciphers are security vulnerable and the solution is to use CTR Cipher instead of CBC Cipher. However, in SI versions 5020602 and 5020603, maverick (the third party api used for SSH/SFTP) version used is 1.4.60 which mandates that CBC Cipher should be present in Client side. Hence, disabling the CBC support using the security property supportCBCCiphers=false will result in SFTP communication failure with key based authentication. To enforce the use of CTR Cipher in SI, we have introduced two new properties : SSHServerCipherList, SSHClientCipherList a) security.SSHServerCipherList is the property to restrict the list of server side ciphers. In the SFTP Server adapter, "Preferred Cipher" drop down will pick the values specified in this property list. b) security.SSHClientCipherList is...

If you get ssh returns “Bad owner or permissions on ~/.ssh/config” then please change the permissions as follows, chmod 600 ~/.ssh/config

http://www-01.ibm.com/support/docview.wss?uid=swg21628336 Sometimes SSHKeyGrabber don't work when we trying to extract Known Host Key from Sterling Integrator UI. The work around for this is disable StrictHostKeyChecking and download the Key from Linux/Windows and Check in the key to Sterling Integrator. $ssh -o StrictHostKeyChecking=no user@sftp.host.com -p 22 Above command will save host key to known_hosts file located .~/.ssh/known_hosts Note: Remove excess content from host key and just keep the key from ssh-rsa followed the key.
