  • 1.  ssh: Resource temporarily unavailable

    Posted Fri February 28, 2025 12:59 AM

    Hi All. I have a question about one of my servers. 

    I have been having issues with running backups on one of my servers as it keeps failing due to SSH but at some point, it connects without me doing anything at all

    See below.

    [pqaWASCPS02] / #
    [pqaWASCPS02] / # ssh -vvv s2029809@brktsmap03
    OpenSSH_8.1p1, OpenSSL 1.0.2u  20 Dec 2019

    Hi,

    There seems to be old version of openssh, openssl installed in this system which we no longer support.

    openssh is at 8.1 and openssl is at 1.0.2 version

    Is it possible to update to supported versions, openssh to 9.7 and openssl to 3.0.15 from AIX web download pack ? 

    Links to download and install

    Thanks

    Hi Sandeep.

    Thanks a lot for the prompt response.

    I have taken the box to the highest level of SSH and OPENSSL but still didn't work as it was supposed to but while still at that, at some point it worked without me doing anything at all. Later we then realized that the box had too many established connections which left the system with no free ports to establish newer connections. On our troubleshooting we find out that most of the sockets were held by WAS processes and just by restarting WAS JVMs all connection was back to normal.

    Thanks again.
