Hi, Wouldn't 'UseDNS no' in /etc/ssh/sshd_config do it?

I have installed SLES11 SP1 and have configured the Terminal Server concept using IUCV as transport for logging in. Works great but for one 'tiny' little thing. When logging in the orginial login pgm is called (ssh) and ssh uses DNS servers to do lookups of ip-addresses. If no answer from DNS server(s) the timeout is longer than the timeout from iucvconn, thus resulting in a timeout from iucvconn when trying to login = No login. For us the main purpose for IUCV Connect is then there is some network problem, firewall or bad config or...., and in this case it is impossible to login via IUCV. :(( So we can only use it when we don't need it..... Any suggestion ??? (Besides my own script solution to check DNS at network start and disables DNS by creating an empty /etc/resolv.conf) ___________________________________________ Tore Agblad Volvo Information Technology Infrastructure Mainframe Design & Development, Linux servers Dept 4352 DA1S SE-405 08, Gothenburg Sweden Telephone: +46-31-3233569 E-mail: tore.agb...@volvo.com http://www.volvo.com/volvoit/global/en-gb/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ Brabant Water N.V.
