Gateone opens/closes up to 84? New terminals - no CLI

[iamzam]

Installed gateone on centos 5.7 server (rackspace). I installed python 2.7 parallel into /opt/python2.7 and left the Centos default python 2.4 in /usr/bin...

gateone starts fine:

cd /opt/gateone; python2.7 gateone.py [I 111028 23:28:16 gateone:1572] Listening on https://0.0.0.0:443/ [I 111028 23:28:16 gateone:1253] Using google authentication [I 111028 23:28:16 gateone:1288] Loaded plugins: bookmarks, help, logging, playback, ssh [I 111028 23:28:21 gateone:685] WebSocket opened (user@gmail.com).

when i connect to the web interface (firefox 7.0.1) i immediately see scrolling up from the bottom right:

Closed term 1:Gate One Closed term 2:Gate One etc.

up to Closed term 30:Gate One

Sometimes it will go up to 41 this latest time it went up to 86.

on stdout I see: [I 111028 23:31:40 web:1359] 304 GET / (2.2.2.2) 11.32ms [I 111028 23:31:40 web:1359] 304 GET /static/gateone.css (2.2.2.2) 1.10ms [I 111028 23:31:40 web:1359] 304 GET /static/gateone.js (2.2.2.2) 0.70ms [I 111028 23:31:41 web:1359] 304 GET /static/help/help.js (2.2.2.2) 0.72ms [I 111028 23:31:41 web:1359] 304 GET /static/bookmarks/bookmarks.js (2.2.2.2) 0.73ms [I 111028 23:31:41 web:1359] 304 GET /static/logging/logging.js (2.2.2.2) 0.87ms [I 111028 23:31:41 web:1359] 304 GET /static/playback/playback.js (2.2.2.2) 0.87ms [I 111028 23:31:41 web:1359] 304 GET /static/ssh/ssh.js (2.2.2.2) 0.70ms [I 111028 23:31:42 web:1359] 304 GET /style?theme=black&container=gateone&prefix=go (2.2.2.2) 28.79ms [I 111028 23:31:42 web:1359] 304 GET /style?colors=default&container=gateone&prefix=go (2.2.2.2) 15.37ms [I 111028 23:31:42 gateone:685] WebSocket opened (user@gmail.com).

At one point i did see an exception on stdout:

I just noticed the closed issue 16 which is like mine, but chmod 775 on ssh_connect.py doesn't fix the issue for me.

I do have noscript/adblock/requestPolicy plugins installed but if I try in chrome i get:

A communications disruption can mean only one thing...

clicking the + key to open a new terminal gets:

NaN: New Terminal

[liftoff]

You have "dtach = True" but do you have dtach installed?

[iamzam]

I didn't, but i installed it and now i get these errors:

oops, if i scroll up a little after it's done refreshing i see:

^L File "/opt/gateone/plugins/ssh/scripts/ssh_connect.py", line 34 except OSError as exc: # Python >2.5 ^ SyntaxError: invalid syntax

and at the bottom of the screen:

[EOF - dtach terminating]

If I set dtach = False i get the same behavior, but no error in the browser and on stdout:

[root@iamzam gateone]# cd /opt/gateone; python2.7 gateone.py [I 111029 20:44:20 gateone:1572] Listening on https://0.0.0.0:443/ [I 111029 20:44:20 gateone:1253] Using google authentication [I 111029 20:44:20 gateone:1288] Loaded plugins: bookmarks, help, logging, playback, ssh [I 111029 20:44:25 gateone:685] WebSocket opened (user@gmail.com).

same in /var/log/gateone/webserver.log

This is the result of running Gate One using Python 2.5. You need to run it using 2.7. I.e. python2.7 gateone.pt

Ok, great!
I was able to get this working on centos 5.7:

in /opt/gateone/plugins/ssh/scripts/ssh_connect.py i replaced this:

#!/usr/bin/env python

with this:

#!/opt/python2.7.2/bin/python2.7

I guess this would work as well:

#!/usr/bin/env python2.7

as long as:

ln -sf /opt/python2.7.2/bin/python2.7 /usr/bin/python2.7

For future reference for people with centos 5 who can't upgrade python because it's used by things like yum:

I installed python2.7.2 into /opt/python2.7 like this(as root):

wget http://python.org/ftp/python/2.7.2/Python-2.7.2.tgz
tar zxvf Python-2.7.2.tgz
cd Python-2.7.2
./configure --prefix=/opt/python2.7.2 --with-threads --enable-shared
make
make install
echo "/opt/python2.7.2/lib/" >> /etc/ld.so.conf.d/opt-python2.7.2.conf
ldconfig
wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg
sh setuptools-0.6c11-py2.7.egg --prefix=/opt/python2.7.2
/opt/python2.7.2/bin/easy_install pip
ln -sf /opt/python2.7.2/bin/pip /usr/bin/pip
pip install virtualenv
ln -sf /opt/python2.7.2/bin/virtualenv /usr/bin/virtualenv

pyOpenSSL-0.13 wouldn't install so i installed 0.12:

/opt/python2.7.2/bin/easy_install http://pypi.python.org/packages/source/p/pyOpenSSL/pyOpenSSL-0.12.tar.gz

then:

pip install tornado

i'm not using kerberos so didn't install that.

then:

unzip gateone.zip
cd gateone.zip
/opt/python2.7.2/bin/python2.7 setup.py install

then configure /opt/gateone/server.conf:

sso_service = "HTTP"
locale = "en_US"
pam_service = "login"
syslog_facility = "daemon"
disable_ssl = False
session_logging = True
session_dir = "/tmp/gateone"
cookie_secret = "ODk5YWJmzOW0NDkYTk5NDxMOWQ1cMmI4NDU3MzFlOTMxO"
syslog_session_logging = True
address = "0.0.0.0"
port = 443
user_dir = "/opt/gateone/users"
log_file_num_backups = 10
logging = "info"
dtach = False
certificate = "certificate.pem"
keyfile = "keyfile.pem"
sso_realm = None
log_to_stderr = False
log_file_max_size = 104857600
session_timeout = "5d"
command = "/opt/gateone/plugins/ssh/scripts/ssh_connect.py -S '/tmp/gateone/%SESSION%/%SHORT_SOCKET%' --sshfp -a '-oUserKnownHostsFile=%USERDIR%/%USER%/known_hosts'"
embedded = False
debug = False
js_init = ""
auth = "google"
log_file_prefix = "/var/log/gateone/webserver.log"
pam_realm = "server"

then:

cd /opt/gateone; python2.7 gateone.py &

Thanks for the excellent software!

Many thanks iamzam! :-)

I had the same problem as you. See my screenshot -> http://i.imgur.com/OHsKw.png

The problem resolved after changing a hashbang from: #!/usr/bin/env python to #!/usr/bin/env /usr/local/bin/python2.7

My environment:

• CentOS 5.2
• Python 2.4.3 (/usr/bin/python)
• Python 2.7.2 (/usr/local/bin/python)

Regards, Scottie

Thanks for posting this HOWTO and I'm glad it is working for you now!
