 From DNS nutshell or from the "DNS and BIND" book the programme

 > check_soa peter-dambier.de

ns1.peter-dambier.de has serial number 2005050401
ns2.peter-dambier.de has serial number 2005050401

Can do.

In the IASON tools there is a hacked version

 > chk1soa ns1.peter-dambier.de peter-dambier.de

soa("peter-dambier.de","2005050401","ns1.peter-dambier.de","195.20.224.105").

 > chk1soa m.root-servers.net peter-dambier.de

error("peter-dambier.de","m.root-servers.net","202.12.27.33","no soa").

IASON compiles on most flavours of unix including Mac OS-X and linux.
