Help with timeout

hi

my script is pretty much working except for the time out

Code:

# $language = "python"

# $interface = "1.0"



def main():

        crt.Screen.Synchronous = True

with open('/Path/to/file/hosts2') as hosts_:

        for host in hosts_:



                crt.Screen.WaitForString("nfs]# ")

                crt.Screen.Send("ssh -oStrictHostKeyChecking=no root@" + host + '\r')

                crt.Screen.WaitForString("word: ")

                crt.Screen.Send("Mypassword" + chr(13))



                szOutput = crt.Screen.ReadString(["# ","word:","ssh: "], 10)

                #szOutput = crt.Screen.WaitForStrings(["]# ","word:","nfs2 # "], 3)

                index = crt.Screen.MatchIndex



                if(index == 0):

                        crt.Screen.Send("echo timeout0" + chr(13))



                elif(index == 1):

                        crt.Screen.Send("mount /rhelrepo;subscription-manager clean;/rhelrepo/scripts/rleon_fix.sh" + chr(13))

                        crt.Screen.WaitForString("]# ")

                        crt.Screen.Send("exit" + chr(13))



                elif(index == 2):

                        crt.Screen.Send("Password2" + chr(13))

                        crt.Screen.WaitForString("]# ")

                        crt.Screen.Send("mount /rhelrepo;subscription-manager clean;/rhelrepo/scripts/rleon_fix.sh" + chr(13))

                        crt.Screen.WaitForString("]# ")

                        crt.Screen.Send("exit" + chr(13))



                elif(index == 3):

                        crt.Screen.Send("echo timeout" + chr(13))

     

                else:

                        crt.Screen.Send("echo timeout" + chr(13))





main()

I am able to attend the 2nd password if the 1st one fails.

But if the host does not connect or can not resolve and falls back to the prompt

Code:

nfs]#

then it does nothing.

I tried in several sections and the timeout just doesnt continue.

I am also not able to echo the hostname into the error file.

Code:

crt.Screen.Send("echo" + host + ">> error" + '\r')

I am missing something .. but i cant figure out it.

Any help or ideas are welcome.

Hi rleon,

You are currently waiting for the stings:

Code:

"# ","word:","ssh: "

The timeout should be triggered if none of these strings appear for the timeout duration. I believe you're running into a problem where the strings you are waiting for are not specific enough, and are accidentally matching rather than timing out.

With a prompt of "nfs]#", it is possible that you are accidentally matching the string "# " in your ReadString.

Perhaps adding your full prompt to the ReadString and handling the case explicitly will give you better behavior.

Code:

ReadString(["# ","word:","ssh: ", "nfs]#"], 10)

…

…

elif(index == 4):

Does handling the case of finding your prompt explicitly give you the needed functionality?

Thanks

i changed the code to

Code:

szOutput = crt.Screen.WaitForStrings(["# ","word:","mbp:nfs #"], 3)

And it still doesnt work

What i noticed was if i cat a file .. it does continue.

So its falling some where but i cant figure out where.

is there a way i can turn on debugging?

rleon,

To get a better idea of what may be happening I will need to review a log file from a connection attempt.

PLEASE DO NOT POST YOUR LOG TO THE FORUMS!

Can you take these steps and send me the resulting log file for analysis?

Video Link: Trace Options Debug Logging in SecureCRT

- Launch SecureCRT and open SecureCRT's main "File" menu and select the "Trace Options" menu item.

- Open the "File" menu again and choose "Log Session..."
--> Specify a path to your Desktop folder and a name of the log file, such as SCRT_Log.txt.

- Now attempt your connection/script again.

- When the script fails, open SecureCRT's "File" menu and look at the "Log Session" menu item. If it has a check-mark next to it, click on it to turn off logging.

- Go to your Desktop folder and locate the SCRT_Log.txt file. Please send the SCRT_Log.txt file to me as an attachment via email. Please don't paste the contents into the body of your message -- please attach it! Send the email to Support@VanDyke.com with "Attn: Eric Forum Post 13388" in the subject line.

It would also be beneficial to include a copy of your full script. You will likely need to rename the script to end in .txt before sending it to ensure it get delivered.

I figured out what the issue is but i don't know how to fix it .

In my top block

Code:

               

crt.Screen.WaitForString("nfs]# ")               

crt.Screen.Send("ssh -oStrictHostKeyChecking=no root@" + host + '\r')                

crt.Screen.WaitForString("word: ")                

crt.Screen.Send("Mypassword" + chr(13))

I am waiting for word from the host i am connecting to.

Code:

crt.Screen.WaitForString("word: ")

Since it times out .. fails I never get word - therefore it never goes into the if statements.

Would the only fix be to do another if statement?

Hi rleon,

It looks like you were working with my co-worker Brittney in this thread. She has provided a link to an updated example script that may fit your needs.
