simple question for you unix experts!

[reaper]

okay.. here is what i am trying to do.  i would like unix to automatically log what i do via telnet to a router.
i sort of have this working - minus my invisibility feature

i type router1.exp , and it logs me into the router, and if i were to type at a blank prompt, the output would go to the file i specified

.exp logs in to the routers and send standard input back to the keyboard, so if i go router.exp>>log the output from the router goes to log.  can i use | or & to get this to work somehow!  there has to be something

[console]

We can't know how unix works because it is incomprehensible.

   j/k


man tee

    tee - read from standard input and write to standard output and files


Hope this helps,

awesome, i got it working with expect:

set lfile argv
log_file -noappend /var/log/$lfile
expect "CISCO2611SCHDY01#"
interact
log_file

so if i wanna log into a router, and have it logged. i type routerX date , and it logs me and creates a log named as you choose

but i'm trying to learn unix better, and tee sounds very useful

but i might need tee for stuff i don't have scripts for !

i don't think tee, pipes, or redirect will work. looks like i have to mess with stdout. we will see how much community college paid off, i took for c classes there!

# redirect stdout to a disk file
    import sys
    saveout = sys.stdout
    outfile = open('output.txt', 'w')
    sys.stdout = outfile

    # output stuff
    print 'hello world'

    # restore stdout
    outfile.flush()
    outfile.close()
    sys.stdout = saveout:

if you are using system V based (like Solaris), you should be able to type script <filename>, then everything you type gets re-directed to that file.
been awhile since I wrote an expect script....

what were you using expect for, servers or network stuff?  i love expect it makes my life so much easier : ) . if i type script <file>  the commands i type got to a file - which would be good - but i also need output to go to the file, as well as the screen.  i do have "automatic" logging working now, it's really just typing script <logfilename>  (the script logs from an expect command creating the filename from the argument).

what i want to do is have it create the log file based on the time and the device i'm logging into - i'm suprised there isn't an expect script out there for this (if there is i haven't found it).  i don't think any of these scripts are to portable, obviously because their unique to each device, but i would like to have a template script, that automatically logs via hostname & time.

that would be really nice, because if you are going to log into a router more than once, just create an expect script by altering one or two lines, then when you change stuff, it will be logged - you could also automatic config backups this way.  i guess you could use tftp or ciscoworks or something, but automatic login, and logging is nice via expect
