QUESTION
I'm trying to upload a file to a couple devices at the same time but without success so far. What I'm trying to do is to create 2 workers that follow up a csv containing a list of ips but it duplicates the same task:

QUESTION
I'm working on a script that pulls data from a CSV file and connects to multiple hosts to run commands. The script acts like it's connecting to all of the different devices, however in reality it's only connecting to the first device in the list. What do I need to change to get this working correctly?
Example CSV file:
...ANSWER
Answered 2022-Mar-25 at 15:30for device, info in fetch_hostnames().items():
This for loop is unnecessary, as this is already performing the action to each one of the hosts:
results = exe.map(run_verification_commands, hosts)
Every time run_verification_commands is called, regardless of what was being passed to it, because the for loop is going against the original data, it will always grab the first host.
This can be resolved by instead passing in the data when you set up the concurrent futures:
QUESTION
Is there a way to login with Netmiko to a Cisco device and stay logged in? I have a Python script that should connect every 5 seconds to a Cisco device, but it would be better to login once and stay logged in, and just pull the data from the Cisco device by sending commands via script.
Thank you in advance
...ANSWER
Answered 2022-Jan-23 at 12:42Are you aware of the keepalive parameter? You should also pay attention to the timeout in the device and allow for a noise margin.
QUESTION
I'm new to Python and Netmiko. I;m trying to use netmiko to login to aruba switches. while i pass on some commands using send_config_set, it is erroring out saying "failed to enter configuration mode" am i missing anything here.
...ANSWER
Answered 2022-Mar-19 at 18:55You can use the sample code I wrote below. It will be enough to update the prompt section.
QUESTION
I have been doing some network automation, now I am working with for lops to be able to do not only one at time, so when I ran the code below I see the first router it is successful but the second one has the error netmiko.ssh_exception.NetmikoTimeoutException: Timed-out reading channel, data not available.
So I am testing with 3 routers, the first goes well but the second one never works.
...ANSWER
Answered 2022-Feb-25 at 17:44That was my bad. The code is working fine. I just forgot to add the priv 15 in the other 2 routers.
QUESTION
hopefully this is a quick an easy on! I am trying to do a search for a hostname on a device and then use that hostname to dictate the config that is sent to it via netmiko. I think I'm failing because the output is not on one line. As a test at the moment I am just trying to print the output as follows:
...ANSWER
Answered 2022-Jan-11 at 03:50(?=...)
Matches if ... matches next, but doesn’t consume any of the string. This is called a lookahead assertion. For example, Isaac (?=Asimov) will match 'Isaac ' only if it’s followed by 'Asimov'.
(?<=...)
Matches if the current position in the string is preceded by a match for ... that ends at the current position. This is called a positive lookbehind assertion. (?<=abc)def will find a match in 'abcdef', since the lookbehind will back up 3 characters and check if the contained pattern matches.
Demo:
(?<={).*(?=})
It means to match strings beginning with
{and ending with}
QUESTION
I'm pulling data from a network switch and it comes out as a string like this.
...ANSWER
Answered 2021-Dec-06 at 22:47Going by the conversation on the chat, text parsing seems to be the only way forward. I copied the entire text and saved it on to a file because I assume you have the output of the command stored in a file. For the sake of length of answer though, I tried with running only a few ports instead of all 48. Also Note that this works only if every column has atleast one row with data. This fails if there is a column for which no port has any data
Instead of using readline, I used read() so that I could split it at \n. This essentially removed the \n at the end of each entry in lines when using readlines()
QUESTION
I am trying to use Netmiko and work in 'configuration terminal' mode. Why there only 'enable' mode function and not 'configuration terminal' mode.? (i.e : net_connect.enable())
My program should do these steps:
- login
- change to enable mode
- change to configure terminal
- insert restricted license ( in configuration terminal mode )
- run '_shell' to change from CLI to regular Linux bash.
Editing I tried the following command to enter config_mode and got 'ValueError'.
...ANSWER
Answered 2021-Dec-03 at 13:58Why there only 'enable' mode function and not 'configuration terminal' mode.?
There is a configure terminal mode in netmiko, using conn.config_mode() sends configure terminal to the remote device.
However, you can use send_config_set() which enters configuration mode by default and exits it after the last command was sent. An example of using send_config_set()
