Strange issue using pipes with ssh as root


Hi,

has anyone seen this before, when running an ssh command as normal user via ssh i get results:

ssh picolo 'ls -d /var/sadm/pkg/* | egrep "Prod|Dev|UAT" |cut -d\/ -f5;uname -r;grep -v "^#" /opt/Tivoli/lcf/dat/1/DMXAdaptiveFileSystem.dat'>>sshnotroot
and it creates file
more sshnotroot
Prod
5.10

/ | - | - | - | - | 20 | - | -
/tmp | - | - | - | - | 20 | - | -
/opt | - | - | - | - | - | - | N
/export/opt | - | - | - | - | - | - | N

and now if i run as root (keys havebeen copied and i get directly ssh hostname /bin/ksh -t ) and it gives me root shell

root@goku$ ssh picolo 'ls -d /var/sadm/pkg/* | egrep "Prod|Dev|UAT" |cut -d\/ -f5;uname -r;grep -v "^#" /opt/Tivoli/lcf/dat/1/DMXAdaptiveFileSystem.dat'>sshwithroot

Try breaking up the problem in pieces. For instance, forget about the egrep, cut, etc and try to do a simple ssh with ls/echo command as root.
You could also make ssh more verbose, so it prints more what is going wrong.
Any aliases set up for both root and non-root users?

Hi,

In the first case it logins to picolo server using user@picolo
The second one use root@picolo .

Try to ssh into the picolo server using root user without any command to see if you get any errors.
Also try to log to picolo and run : ls -d /var/sadm/pkg/* | egrep "Prod|Dev|UAT" |cut -d\/ -f5;uname -r;grep -v "^#" /opt/Tivoli/lcf/dat/1/DMXAdaptiveFileSystem.dat form the server console.

Good Luck

Thanks for the suggesstion chaps, but i have tried all this. I've ssh'd in debug mode even trussed the process but i cannot see any reason why it is not working for root. I wonder if it is a bug? Will keep investigating.
