Hahaha. Thanks but no thanks ;). If Sify took over the entire internet and was the sole provider of internet connections even then I wouldn't opt for them :/ Sify is the most Linux unfriendly ISP I've /ever/ seen
:(
Well yes and no.
It is unfriendly in the sense that it does not have the appropriately skilled customer support for Linux and has a very old linux dialer. There were a few issues regarding a new dialer protocol which momentarily locked out linux users but that has been resolved.
Also, there's alternate dialers written for linux (i've written one too, called antidialer) if you don't like the sify stock dialer.
Other than that I don't see anything linux unfriendly in any manner. I have been using sify for almost 3 years now without too many complaints. It has an almost completely hassle-free setup with no additional equipment required at all. Just connect to their LAN and you're done.
Issues with Sify Internet that are not limited to linux users: 1) Sify terms and conditions consider more than 6 hours as commercial usage. They haven't taken action against anyone on it though. Otherwise i would have been disconnected ages ago ;-) 2) Their services is slightly poorer than others during the rainy seasons (especially during thunder & lightning) since their broadband service is wireless based (LANS connected to the backbone wirelessly)
Maybe you could mention a few more to support your statement of them being linux unfriendly.
