Add BGPQ3 to Arista EOS #69

Open dudster83 opened 2 years ago

dudster83 commented 2 years ago

Hi I'm trying to install BGPQ3 directly on Arista EOS device. The last version I could find for bgpq3 is 0.1.35 which requires the EOS to be 64 bit If i'm trying to add this on the switch I get the following error

SW1EOS#extension bgpq3-0.1.35-0.el7.x86_64.rpm % Error installing bgpq3-0.1.35-0.el7.x86_64.rpm: RPM install error: Transaction check failed: libc.so.6()(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64 libc.so.6(GLIBC_2.14)(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64 libc.so.6(GLIBC_2.15)(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64 libc.so.6(GLIBC_2.2.5)(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64 libc.so.6(GLIBC_2.3)(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64 libc.so.6(GLIBC_2.3.4)(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64 libc.so.6(GLIBC_2.4)(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64 libc.so.6(GLIBC_2.7)(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64 libnsl.so.1()(64bit) is needed by bgpq3-0.1.35-0.el7.x86_64

I did found a version that works on 32bit EOS but its missing some attributes - 0.1.31

bgpq3 version: 0.1.31 Copyright(c) Alexandre Snarskii snar@snar.spb.ru 2007-2015

I'm missing the -F attribute to use bgpq3 -F "permit %n/%l le 24\n" AS-NV >/mnt/flash/pl-bgpq3/pl-cellcom-v4.txt Or the -s to get this numbered for EOS as it requires it as a syntax

Is there any version newer than 0.1.31 that will work with 32bit EOS?

Strictly saying, it's not bgpq3 requirement but rather it's rpm built for x86_64 arch. You may try this one instead: http://snar.spb.ru/prog/bgpq3/bgpq3-0.1.36.1-0.i686.rpm however, no guarantees: I'm not a big fun of Linux and it's the first RPM I ever built..

Thanks for your quick reply, i'd tried to use the rpm you'd provided but there's still a dependency on libc.so.6(GLIBC_2.28) I'll try using the 0.1.31 version and manipulate the output with some bash commands thanks

Another try: http://snar.spb.ru/prog/bgpq3/bgpq3-0.1.36.1-static1.i686.rpm this time it's statically linked, so libc shall not be a dependency.

Hi Alexandre , I'll give it a go on another machine I have I'd just finished deploying the solution i needed with the limitations I had by manipulating the output

bgpq3 -4 -P -A -l AS-NV-IN | awk '{print substr($0, index($0, $4))}' > /mnt/flash/PL-BGPQ3/RAWFILE-AS-NV-IN.txt sed '1d' /mnt/flash/PL-BGPQ3/RAWFILE-AS-NV-IN.txt > /mnt/flash/PL-BGPQ3/SRC-PL-AS-NV.txt

I'll update this post later for any future interest

it didn't work either as an extension to Arista EOS. I'm currently using the old version of bgpq3. if in the future anyone will happen to test it on EOS, it would be great. A great useful tool. Thanks Alexandre!
