Juniper CLI - make your work faster
In this next lines you are going to read about some commands that can make your work with Junos easier
(Simple RegExp and Junos examples)
This list is mainly for thought memorizing.
1. show interfaces in two lines list with MTU
before:
[edit]
user@switch# run show interfaces terse
Interface Admin Link Proto Local Remote
ge-0/0/0 up up
ge-0/0/0.0 up up eth-switch
ge-0/0/1 up up
ge-0/0/1.0 up up eth-switch
ge-0/0/2 up down
ge-0/0/2.0 up down eth-switch
... output truncated
after:
[edit]
user@switch# run show interfaces terse |except "\."
Interface Admin Link Proto Local Remote
ge-0/0/0 up up
ge-0/0/1 up up
ge-0/0/2 up down
... output truncated
3. show ipv4 address on your switch or router, show only interfaces:
{master:2}
user@switch> show interfaces terse |match "inet "
ge-0/0/12.3212 up up inet 10.32.1.41/30
ge-0/0/13.3200 up up inet 10.32.1.245/30
ge-0/0/13.3202 up up inet 10.32.1.1/30
ge-1/0/1.107 up up inet xx.yyy.zz.1/30
ge-1/0/13.3201 up up inet 10.32.1.249/30
ge-1/0/13.3203 up up inet 10.32.1.5/30
...
{master:2}
user@switch> show interfaces terse |match "inet " |trim 44
10.32.1.41/30
10.32.1.245/30
10.32.1.1/30
xx.yyy.zz.1/30
10.32.1.249/30
10.32.1.5/30
...
You could then save it to text file (add | save filename ad the end of command
show interfaces terse |match "inet " |trim 44 | save ipv4.txt
) and transfer your linux.Then do some things with it. For example calculate subnet address from ip address with ipcalc i.e.
So. I did a batch file
from file like this:
10.32.1.41/30
10.32.1.245/30
to file like this:
ipcalc 10.32.1.41/30 | grep Network >> networks.out
ipcalc 10.32.1.245/30 | grep Network >> networks.out
with this two commands:
sed -e 's/^/ipcalc /' ipv4.txt > networks.sed1
sed -e 's/$/| grep Network >> networks.out/' networks.sed1 > networks.sed2
chmod a+x networks.sed1
bash networks.sed1
hopefuly gives you
4. just another tidily output for sflow interfaces (EX4200 Junos 10.0S10)
show interfaces terse |match "eth-switch|aenet" | match "ge|xe" | no-more
ge-0/0/0.0 up up eth-switch
ge-0/0/1.0 up up eth-switch
ge-0/0/2.0 up up eth-switch
ge-0/0/3.0 up up eth-switch
ge-0/0/4.0 up up eth-switch
ge-0/0/5.0 up up eth-switch
ge-0/0/6.0 up up eth-switch
ge-0/0/8.0 up up aenet --> ae6.0
ge-0/0/10.0 up up eth-switch
... And you need to throw it edit it with spreadsheet or via bash or something else.
Remove text after space, then add string to beginning of line.
sed 's/ .*//;s/, .*//' sflow01.txt | sed s/^/"set protocols sflow interfaces "/
(Simple RegExp and Junos examples)
This list is mainly for thought memorizing.

How to install xerox workcentre 3210 on ubuntu 11.10
You have two possibilities
A) run shell script from extracted WC 3210 Linux Driver or longer manual method. Manual method doesn't install -for me- unnecessary files, icons, applications.
1. Download WC 3210 Linux Driver from this webpage.
2. Extract downloaded file to your desktop.
3. find these two extracted files wc3210.ppd (/home/jozef/Desktop/Linux/noarch/at_opt/share/ppd/wc3210.ppd) and rastertosamsungspl (/home/jozef/Desktop/Linux/i386/at_root/usr/lib/cups/filter/rastertosamsungspl)
4. try to install new printer from menu
4a. run (X)ubuntu menu -> System -> Printing)
4b. add printer - Network Printer - select your xerox 3210
4c. from window Choose Driver select "Provide PPD file" and select wc3210.ppd
5. your ubuntu screams this:
and you will go to next step
6. Run terminal (Ctrl+Alt+T)
7. copy file rastertosamsungspl from step 3 to /usr/lib/cups/filter/ as root:
sudo cp /home/jozef/Desktop/Linux/i386/at_root/usr/lib/cups/filter/rastertosamsungspl /usr/lib/cups/filter/
That's all

juniper ex8200 and bgp full table, :-( [j-nsp] TCAM full on EX8200?
I created three scenarios for customer. One of that was ex8208 with acting also like bgp full view router. But after reading this I am going to consider it
http://www.gossamer-threads.com/lists/nsp/juniper/31959?nohighlight=1#31959
Ex8208 has may have some problem with full routing table. :-(

New ubuntu 11.10 - tomorrow 13. oct 2011
"Oneiric Ocelot" is the code name for Ubuntu 11.10, scheduled for release on 13 October 2011. See the Oneiric release schedule.
[j-nsp] JUNOS and 128.0.0.0 martian (JFYI), IANA
INANA allocated new addresses. These are martians for Juniper.
for example
https://apps.db.ripe.net/whois/lookup/ripe/inetnum/128.0.0.0-128.0.7.255.html
Take a look at RFC5735 which obsoletes RFC3330.
So if you have it as martians, you possibly cannot route to that remote subnets. Also transit ISPs should change this if they dont route them.
Workaround - Deleting Martian Addresses:
http://www.juniper.net/techpubs/en_US/junos10.2/topics/usage-guidelines/routing-configuring-martian-addresses.html#id-10349412
source: http://puck.nether.net/lists/juniper-nsp/0319.html
UPDATE!!!:
https://apps.db.ripe.net/whois/lookup/ripe/inetnum/128.0.0.0-128.0.7.255.html
IANA changed it. there was mail.ru now there is nothing
for example

Couple updates about it.
martians are per table in Junos, so if you run internet in vrf (yes,
there are such people!) you need to use that command per routing instance.
RIPE NCC was awared about this issue and now reallocate blocks to those
who got addrs from 128.0.0.0/16
