[Xorp-hackers] XORP beginner question: xorpsh has some connect problem

[frank hu]

Thanks for the kind help!

It still has the same error even after I switched to use
"xorp_install.bash" script. My bad in my earlier email not clearly saying
the usage of "sudo" in "chmod" and "chown". I did run "chmod" and "chown"
as super user. otherwise, the command will just fail.
I tried to use xorp_install script and found that it has some extra info.
It tried to add the user "lanforge" to the group "xorp". I didn't see
that it was documented anywhere in xorp.net. So is it really necessary?  I
also saw the script tried to add the user "xorp" to the root group. Is that
necessary as well?

.... many errors...

I checked the unix socket file /var/tmp/xrl.iE6G21.

$ ls -l /var/tmp/xrl.iE6G21
srwxrwxr-x 1 root xorp 0 2011-12-06 08:39 /var/tmp/xrl.iE6G21
$ cat /etc/group | grep xorp
root:x:0:xorp
xorp:x:1001:feng,root,xorp,lanforge
feng at feng-desktop:~$
"

Anyway, I figured out a possible way to get xorp to work.... Instead of
running xorpsh as a normal user "feng", I tried to run it as a normal user
"xorp" and then it gave me the CLI interfaces..

"
$ su xorp
Password:
$ pwd
/usr/local/xorp
$ ./sbin/xorpsh
