Re: Strange login error -- Password read timed out.

I already don't run portmapper on any of my systems except 1 NFS server. No NFS clients run even portmapper or the NFS client daemons. They are not required.

Portmapper has nothing to do with a login. Portmapper is strictly for systems using RPC. Not sure what other problems you might be facing; but it is not with Portmapper. Standard AIX/Unix security is to disable portmapper unless you have an RPC client requiring it.

Sorry; but no issues not running portmapper on 30+ systems with no issue.

xxxxxx@xxxxxx:/home/xxxxxx:> lssrc -s portmap
Subsystem Group PID Status
portmap portmap inoperative

xxxxxx@xxxxxx:/home/xxxxxx:> rpcinfo -p erpdb1
rpcinfo: can't contact portmapper: RPC: Rpcbind failure - RPC: 1832-020 Failed (unspecified error)

Again, common security practice to disable the portmap service.

Sorry, but portmap does not affect logins. Possibly an RPC application hung on your system when it could not contact the portmapper when you removed it; but no issues here...

Try it for your self, disable your portmapper and reboot. After the reboot, watch how long it takes to log in. Without the portmapper, your AIX Server may take upwards to 10 minutes before it allows a user to sign in.

Not meaning to sound like a bashing; but portmapper has absolutely nothing to do with logging into a system unless it is via an RPC service. If the connection password request is timing out on telnet connections and a login prompt is being received; then inetd is listening for port 23 and launching telnetd to provide such a login.

Just want to explain, not complain...

Can you sign-onto the console, from the rs232 connection?

Fellow AIXers,

When I try to log into my AIX system, I see this message:

Entre com o prefixo do sistema: marlon
/dev/pts/9: 3004-031 Password read timed out -- possible noise on port

Have you seen that message?



Abraços,
