Did anyone else experience a Level 3 outage in the last couple of days? Seems like we've been affected with quite a few VPNV4 outages (one that lasted for upto 9 hrs) and didn't get resolved until they rebuilt their vpnv4 address family on their PE router(s)?

I've had a handful of clients contact me over the last week with trouble using SCP (usually WinSCP) to manage their website content on my servers. Either they get timeout messages from WinSCP or a message saying they should switch to SFTP.
After getting a few helpful users on the phone to run some quick tests, we found port 22 was blocked.
When my customers contacted Frontier, they were told that port 22 was blocked because it is used to transfer illegal files.
I called them, and got the same ridiculous excuse.
Just a friendly heads-up to anyone from Frontier who might be listening, I have a few additional ports you may wish to block:
80 - Allows users to use Google to search for illegal files 443 - Allows users to use Google to search for illegal files in a secure manner 69 - Allows users to trivially transfer illegal files 3389 - Allows users to connect to unlicensed Windows machines 179 - Allows users to exchange routes to illegal file shares 53 - Allows people to look up illegal names

Can't help to add that there are
- port 21 that allow users to give commands to examine the existence and initiate transfers of illegal files;
- ports 1025 - 65535 that allow users to create data streams to actually transfer illegal files in an (oh my) passive mode.

I wonder if their support is just confused, and Frontier is really blocking outbound tcp/22 to stop complaints generated by infected customers with sshd scanners. After all, most of their customers probably don't know what SSH is.

It's been a while since I did this, but you can select an additional port to accept SSH connections. A Google search indicates you can specify multiple ports in OpenSSH. Picking the right port to use is an exercise, though, that will depend on what other services you are running on your server.
People with sane ISPs can use the standard port. People on Frontier can use the alternate port, which shouldn't be firewalled by the provider. If Frontier is running a mostly-closed firewall configuration, then you have to be damn careful about the port you select.

Ahem, just to clarify, he is not talking about inbound on the Frontier connection, but outbound *from* the Frontier network.
Akin to the "Let's block outbound port 25 (smtp)".
This is just a really really bad idea m'kay.

Hi folksŠ we have a point and have a 63km between point A to point BŠ. We have a sigle fiber ( only one fiber) and use a fiberstore sfp+ 10GB dibi 1270/1330 module to connect these sites. All attenuation are okŠI don¹t have any trouble on fiber Š. I have received this signal on my sfp+:
Receiver signal average optical power : 0.0026 mW / -25.85 dBm
Does anyone know if have some possible to amplifier this scenario to get more 7db ? Is it possible to put any booster or any way to solve this? I think to use a optical PreAmlifierŠbut I don¹t know if is possible because my scenario have just one fiberŠor, use a ROPA- remote optical pumping amplifier) because I have 63kmŠ Does anyone have some idea?

That's easy:

I always have at least one sshd listening on port 443. For all the hotel, coffee house, customer networks blocking ssh.
You can even multiplex and run ssh and ssl on the same port:

Nothing helps promote a free and open Internet more than micromanaging your users' download activity.
Not really sure how someone comes to the conclusion that nobody really *needs* ssh for anything.

All,
Info gathered off-list indicates this may be a couple of issues in our case - possible routing leak by 18978 (check your tables!) and more specifics on our prefixes from 4795 that we couldn't see before the leak hence the apparent hijack.

Hi,
2015-03-26 15:08 GMT+01:00 Randy <amps@djlab.com>:
On Thursday March 26th 2015 at 12:18 UTC (and on-going) we are seeing more specifics on one of our prefixes. Anyone else seeing similar or is it just us?
198.98.180.0/23 4795 4795 4761 9304 40633 18978 4436 29889 198.98.182.0/23 4795 4795 4761 9304 40633 18978 4436 29889
We (as3215) are seeing almost the same path with 40633 18978 3257 3215, for some quite a lot of prefixes.
Some alerts from bgpmon: 193.251.32.0/20 271 6939 40633 18978 3257 3215 193.251.32.0/20 271 6939 40633 18978 3257 3215
We are not directly connected to 3257. Looks like 18978 deaggregated to /20 and reannounced to 40633 (LAIX).
Rgds, pierre

Same here. These Indosat guys can't seem to catch a break =/

We are AS 10326 130.215.0.0/16 and I just received a BGPmon alert as well:
130.215.160.0/20 4795 4795 4761 9304 40633 18978 4436 10326 130.215.176.0/20 4795 4795 4761 9304 40633 18978 4436 10326

common point looks like LAIX ? their routeserver go crazy perhaps? or did they change in/out prefix management information?

Hi Randy,
Assuming that your prefix is 198.98.180.0/22 (AS29889 - FSNET-1 - Fast Serv Networks, LLC) none of the mentioned more specifics are currently seen from the RIPE NCC's RIS network, see the Looking Glass widget:
https://stat.ripe.net/198.98.180.0/23#tabId=routing https://stat.ripe.net/198.98.182.0/23#tabId=at-a-glance
though there has been some BGP activity going on since 11:49:42, see the BGPlay and BGP Update Activity widget. In both cases the originating ASN was AS29889.
Cheers, Christian
