Console - root command prompt displayed twice after hitting enter
Dear All,
I hope you can help me.

I have a pair of E2900's I've inherited. Both running Solaris 9. Both have LOM> consoles. The problem I'm experiencing only occurs when connected to the /dev/console tty. Whenever I hit 'Enter' for a new line, I receive two new lines: -

Code:
myhost#                    <--- Hit Enter here
myhost#
myhost#                    <--- Hit Enter here
myhost#
myhost# tty               <--- Hit Enter here

/dev/console
myhost# myhost#

I have tried searching all other places for help, I suspect either my LOM is setup incorrectly or my inittab is.

Code:
myhost# myhost# cat /etc/inittab

ap::sysinit:/sbin/autopush -f /etc/iu.ap
ap::sysinit:/sbin/soconfig -f /etc/sock2path

Your /etc/inittab looks fine. I do not think that is the problem.

Anything look strange in either my /etc/profile or /.profile then...

/etc/profile...


Code:

something similar on my SF4800 and SF-e4900 consoles as well.

I don't think this is related to something present in .profile[s], else it would have caused the same behavior at normal prompt ( which is not the case. )


What I have been using to eliminate this during major upgrades is "CTRL-j" which simply sends single enter and everything works perfectly okay.

Yes, that seems to work. A permanent fix if anyone know's one would be better. Seems like its the old carriage return & new-line being sent when only one of them is required. I wonder if any of these stty settings might be the culprit: -

Code:
myhost# myhost# stty -a

speed 9600 baud;
rows = 0; columns = 0; ypixels = 0; xpixels = 0;
csdata ?
eucw 1:0:0:0, scrw 1:0:0:0
intr = ^c; quit = ^\; erase = ^h; kill = ^u;
eof = ^d; eol = <undef>; eol2 = <undef>; swtch = <undef>;
start = ^q; stop = ^s; susp = ^z; dsusp = ^y;
rprnt = ^r; flush = ^o; werase = ^w; lnext = ^v;
-parenb -parodd cs8 -cstopb hupcl cread -clocal -loblk -crtscts -crtsxoff -parext
-ignbrk brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl -iuclc

I compared your stty output with the one from some of my servers. The only difference I could find - besides erase - is, that you have local mode off (flag -clocal) and it's on here.

This is the output from a V490 console via RSC:

Code:
# stty -a
speed 9600 baud;
rows = 0; columns = 0; ypixels = 0; xpixels = 0;
csdata ?
eucw 1:0:0:0, scrw 1:0:0:0
intr = ^c; quit = ^\; erase = ^?; kill = ^u;
eof = ^d; eol = <undef>; eol2 = <undef>; swtch = <undef>;
start = ^q; stop = ^s; susp = ^z; dsusp = ^y;
rprnt = ^r; flush = ^o; werase = ^w; lnext = ^v;
-parenb -parodd cs8 -cstopb hupcl cread clocal -loblk -crtscts -crtsxoff -parext
-ignbrk brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl -iuclc
ixon -ixany -ixoff imaxbel
isig icanon -xcase echo echoe echok -echonl -noflsh

I just recalled this sort of behavior is usually started after a longer period of activity on the Consoles.

I'm not sure about this, but it happens likewise .

I just tried one of the consoles on SF-e4900 and its working fine now and I still remember that we had to use the same key-sequence for the whole of night in a upgrade.

hergp:

Can you please check if this time based scenario is there with v490's console as well?
