For Roll-your-own it's hard to beat a combo of MIMEDefang/SA/Clam (MD is a milter, so sendmail or postfix needed). The MIMEDefang developer also started a company which sells CanIT Pro, an appliance version of the above with additional features/web interface/support Ironport (reassuringly expensive) has worked great here at work. ~JasonG

Are we talking virus protection ? You might want to look at something like amavisd-new or clamav in SMTP proxy mode. http://www.ijs.si/software/amavisd/ http://www.clamav.net/ Amavisd-new together with clamav and SpamAssassin will block a big chunk aof spam and viruses. Some vendors like Barracuda and IronPort do this as well, if you're willing to pay. Cheers, Phil

SIP trunk silliness after peering change
by Adam Greene 05 Nov '09

05 Nov '09

Hi, Does this make any sense? We (ASN 11579) peer to (2) WBS routers (ASN 19080). We lost our link to the primary WBS router. After that, calls coming in over our Bandwidth.com SIP trunks were fine in one direction only. Callers could hear us, but we couldn't hear them. After 45 minutes, things righted themselves. Later on the primary WBS link came back up and went down again 5 minutes later (not WBS's fault, we brought up and took down the BGP session). Again we experienced the one-direction-only problem with Bandwidth.com, but this time it lasted 2.50 hours. Again things eventually righted themselves without our intervention. Traces from us to Bandwidth.com were fine during the outage. We were unable to get a trace from Bandwidth.com to us during the outage. Maybe the only way to figure out what is going on is to get that return path trace during an outage. Has anyone else experienced issues of this nature (extended outage of voice in one direction only) specifically with Bandwidth.com SIP trunks as a result of simply changing one's peering with one's upstream provider? Thanks, Adam

HE.net, Fremont-2 outage?
by Tico 04 Nov '09

04 Nov '09

Hey guys, I can't get through to Hurricane Electric, and they seem to be having an outage at their Fremont-2 facility again (as of 17:30 UTC or thereabouts) -- ticket system is unanswered, phones go to voicemail, all equipment is unreachable. Does anyone here have a presence at 48233 Warm Springs Blvd, that can provide any information about this? I got hit by the ATS failure last month, so I guess it's possible that that equipment may have flaked again. -t

Anyone having complaints about connectivity from people in asia?
by Drew Weaver 04 Nov '09

Packet loss, latency, etc? We have 6 connections and there doesn't seem to be any real theme between source/dest IPs except everyone complaining appears to be in Asia (pakistan, etc). -Drew

ip options
by Luca Tosolini 04 Nov '09

04 Nov '09

Experts, out of the well-known values for ip options: X@r4# set ip-options ? Possible completions: <range> Range of values [ Open a set of values any Any IP option loose-source-route Loose source route route-record Route record router-alert Router alert security Security stream-id Stream ID strict-source-route Strict source route timestamp Timestamp I can only think of: - RSVP using router-alert - ICMP using route-record, timestamp But I can not think of any other use of any other IP option. Considering the security hazard that they imply, I am therefore thinking to drop them. Is any other ip options used by: ospf, isis, bgp, ldp, igmp, pim, bfd? Thanks, Luca.
