Problem

After updating SLES15 SP1 to SP2 or SP3 you might encounter the following when monitoring something via SSH:

fail: ssh: symbol lookup error: ssh: undefined symbol: EVP_KDF_CTX_free, version OPENSSL_1_1_1d

Solution

This is a SLES15SP2 issue, and as of now, there is only a workaround. Just add either of those settings in your SSH rule before your commands:

LD_LIBRARY_PATH=/usr/lib64 ssh root@$HOSTNAME$ /usr/bin/check_mk_agent  

unset LD_LIBRARY_PATH; ssh root@$HOSTNAME$ /usr/bin/check_mk_agent
